commence test and tune!

[jminor]

I'm starting to set-up my Vmax for the season. This I'm sure will be the first of many set-ups until I'm happy! I just put a .720 camo track under it and re-installed my psi's after I took off the easy steer! (all you psi owners who have tried this will know what I mean) So now I'm ready to address clutching. Yammiegod if your out there or anyone else! What I have is the 97 weights in there now but the former owner (Big Bob) got one of Yammiegods setups, blue spring 8bu-00's and some helix, I can't remember the cut but I could check. Will this setup work with the quads as good as it would with the stock setup or do I have to throw more weight at it?Thanks all!

[YAMMIEGOD 3:16]

DUDE, FIRST LET ME SAY DON,T EVER BE AFRAID TO ASK ME QUESTIONS, FOR HELP, OR GIVE YOUR OPINION. YOUR ONE OF THE GOOD GUYS ON THIS SITE AND ARE VERY BRAND LOYAL. NOW., FIRST MY STOCK 800 FAST TRAIL SET-UP IS PROBLEY WHAT BOB GAVE YA. HAUCK BLUE, STOCK WEIGHTS 8BU, 49-43 HELIX. THIS SET-UP ROCKS IN A 800 STOCKER. THE 87 WEIGHTS ARE 8BU-10 WHICH ARE NOT AS AGRESSIVE AS THE DRAG RACE FRIENDLY 8BU-00. MAYBE WE CAN BUILD A SET=UP OFF OF THEM THOUGH FOR YOUR 2000 F.T. RUNS.NOW QUADS. IF YA RUN 8BU-00 WITH QUADS. YOU MUST RUN 17.2 RIVETS IN TIP AND INNER. RUN SAME HELIX @ 100 DEGREE WHICH IS 1-9. RUN HAUCKS BLUE PRIMARY BUT YA MIGHT NEED ENGAGEMENT SHIM. NEED TO BE AT LEAST AT 4800-5000. GOOD LUCK AND POST RESULTS. 3:16 (tony)

GOOD LUCK AND POST RESULTS. 3:16 (tony)


Would love to hear how it worked out jminor. Please keep us posted.

I will give mother nature a call and she will dump a few feet of snow for ya soon. ;)

[jminor]

Thanks Guys and especially you Tony! We are all out to showcase our Vmax4's at the end of the day. Hey, I own a 05 Rx1 and thats all good but when it comes down to it my "go fast machine" is going to be the Vmax! It's easier to throw money at the 4 stroke to make it go fast but its not as rewarding. I know we are all on the same page... now you guys know. I tried my V4 on the grass with stock weights and the helix you recomended for the set-up to Big Bob very quickly. Basically just a roll on hole shot, 100'. First reaction is it needs alot of weight in the primary! First run for fun, had a good feeling it would fall on its face and it did. No big deal, it is what it is. I am leaning toward seeing what I can do with those weights for top end over the 8bu's as well. They say there not as agressive and smoother all the way through right? What if I loaded some weight to them and tried the heavier spring? Would it be easier to squeeze top end over the 8bu's? I need snow, thats all there is to it. As for the jets, stock at the moment, but I suppose i should get them right before WOT!!

[jminor]

RDL when I figure this out to the point where I believe in the setup I will definately share, I've gotten so much from this site. I've cruised alot of snowmobile sites but when it comes to taking people at their word this is the only site I trust!

[YAMMIEGOD 3:16]

THE TEST RUN YOU MADE WAS WITH THE 97 800 8BU-10,s ? WITH MY HELIX AND THE HAUCK BLUE ? 3:16 (tony)

[jminor]

Not the hauck blue just the helix.I think that helix is too much for the stock setup which I know is not the way you intended. What if I try the hauck blue without the shim? I'm not looking for crazy holeshot, but more the 30 mph. and up pull. I also wonder are the
8bu-00's heavier than the 8bu-10's? Maybe I'll put your 00 setup on the 10 setup. Do you think the smoother curve of the 10 may help me get more top end?

[YAMMIEGOD 3:16]

DUDE, HAUCK BLUE WILL WORK FINE WITHOUT SHIMS. STOCK SET-UP WILL PUKE WITH THAT HELIX, AND IT SOUNED LIKE IT DID!! ANYWAYS ENGAGEMENT SHIMS ARE ONLY TO FINE TUNE ENGAGEMENT. WITHOUT SHIMS, YOU STILL SHOULD BE AT 4500. BUT DON,T GO ANY LOWER. THE 8BU-00 ARE HEAVIER THAT THE 8BU-10. THEY ARE ALSO WAY MORE AGGRESSIVE . RUN THE 10,s IF YA LIKE WITHOUT ANY SHIMS IN PRIMARY, JUST THE HAUCK BLUE WITH A 49-43 HELIX AT 2-6 OR 70 DEGREE. ALSO TAKE TOP GEAR DOWN ONE TOOTH. YOU MIGHT LIKE THAT RIGHT AWAY. might be a nice all- around set-up. 3:16 (tony)

Do you mean 2-6 / 80 degree? or 2-5 70? I think the engagement was 3000-3200 I don't remember exactly but yeah it was a pooch!

[YAMMIEGOD 3:16]

that was problem, engagement wayyyyyyyy to low. I MEAN 1-6 @ 70 DEGREE. THERE IS NO #5 ON YAMAHA SECONDARY LOCATIONS. !! 3:16 (tony)

[jminor]

I'm going to try a set of heavy hitters that I kept from a viper I sold. The weights weigh 48.7 but are fully adjustable. that's very close to the weight of the 8bu-00's stock plus like I say I can load weight to them. Do I need to change the cover on the primary or is the 97 V4 the same as the srx/viper? Also the spring that came with the HH's is alot longer than the blue Hauck but I think I still try the Hauck.

[Skinner]

Josh

Just got a set of T-weights from Hauck with the orange spring for higher engagment. Do you add weight to the heavy hitters by adding different or additional screws? I would like to know how those weights shake out for ya. I will weigh the weights alone tonight and see how they compare to your 48.7 gms. Pat tells me to load these weights up but this motor is fully modded. I have to double check my notes but I think 48.7 is just about the weight of a stock 8bu.

[YAMMIEGOD 3:16]

8BU,s ARE 48.7 grams. 8bu-10,s are 45.7 grams. I HAVE NEVER TRYED HEAVY HITTIERS SO I CAN,T HELP YA WITH SET UP. I BELIEVE SOMEBODY SENT DEAN A HEEL CLICKER SET-UP FOR THE VMAX 4 ON THE TECH PAGE. YOU WILL NOT NEED TO CHANGE COVER FOR HAUCK BLUE, DON,T KNOW ABOUT HEEL CLICKER SPRING. !!

[jminor]

48.7 grams is the weight of my heavy hitters with screws in them already (more like bolts) My question is the cap doesn't matter for the weights just the spring right? I have a feeling I'm going to have to put more weight into these because compare a viper motor to a Vmax4 with psi's! I think more weight is in store! What is the difference between the orange spring and blue one?When Hauck says to load them up whats he talking 54-58 grams? Is that with quads?

[YAMMIEGOD 3:16]

DUDE , PRIMARY CAP OR COVER HAS NOTHING TO DO WITH WEIGHTS. PRIMARY SPRING ONLY. A VIPER MOTOR COMPARED TO A VMAX 4 WITH QUADS, DAY AND NIGHT UNLESS YOUR VIPER WAS A BIG BORE WITH TRIPLE PIPES. DUDE REMEBER A VMAX 4 WITH PSI QUADS YOUR PROBLEY LOOKING AT 170+ hp. ALSO SOME OF THOSE SET-UPS I GAVE YA WERE FOR THE STOCK 800 TWINS. NOW ORANGE HAUCK AND BLUE HAUCK DEFFERECE IS ORANGE HAS A HIGHER RATE AND TOTAL FORCE. THIS WILL AFFECT YOUR ENGAGEMENT AND SHIFT OUT RPM. THE TERM LOAD THEM UP MEANS RUN HEAVY WEIGHTS. ! 3:16 (tony)

[jminor]

Everything you said I know and agree with thats why I say the 48.7 from the viper isn't enough and I might end up around 54-57? I'll try the weights as they are at first with the blue spring. Is the orange a higher engagement over the blue?

[Skinner]

Josh

I run an orange spring with one shim in my improver, (800). Stock cover with no spring bind, 17.2mm rivets in both holes, stock 8bu weights. Quad Aaens.
Engagement from what I remember last year is at 5300. I used the blue spring for a trail set-up, to low of engagment for drags. By the way, did ya get your tubes? Its easier to go hunting in Russia than to send parts to Canada.

Skinner

[YAMMIEGOD 3:16]

THATS EXACTLY WHAT I RUN IN MY 96 800 INPROVER ON ICE, JUST WHAT DAVE WROTE. ONLY THING I MIGHT TRY DEFFERENT PRIMARY SPRING THIS YEAR. !! 3:16 (tony)

[YAMMIEGOD 3:16]

AND MINE IS WITH PSI OUADS!!!!! 3:16 (tony)

Tony,
Ya loo'kin for higher or lower engagement?
I need to talk to you about the jetting in my 00 SRX, will call ya later

Skinner
did'nt get the tubes yet.Why hunt in Russia, have you seen the Canadian beaver! Do you think I'd run out of top end with that setup in 2000'? I think I'll try to get that weight onto those heavy hitters. If it doesn't work Ive got a set of 8bu-00's on my shelf and I'll run your guys setup. After all it comes recommended by two of the best!! Also like Tony says maybe I should run that clutch setup and gear differently than you guys.

[Skinner]

Josh

I think the clutch set-up would be OK, I would probably try running the stock gears for 2000 ft. I think if you run a smaller gear on top, you will flatten out long before 2000 feet. Watch your tach, you wanna make sure your pullin all the way through. Would love to hunt canadian beaver, think ya could get me a tag???:D

Skinner

[jminor]

Skinner just don't make a mistake and snag a muskrat!! Just got home to find the lowering tubes, will try them in the next few days and let you know. Thanks again. As for gears, if anything I was kinda leaning to going up one on the bottom, but will run the stockers for now and see.

[jminor]

what do the 17.2 rivots put the total weight up to guys? My gut feeling is I need 53-55 grams per then I think that helix of yours will perform Tony!!!

[jminor]

Tony, Skinner, anyone with the 17.2 rivots do you know the total weight!?? Tomorrow I should be able to try the heavy hitters @ 48.7 grams but the feeling of spinning it on the sled stand feels like its very light.

[vmax4rules]

I list 2 different 17.2 rivets in my chart.

90261-06035-00 (5.0 grams each)

90261-06033-00 (4.5 grams each)

I think the 4.5's were what came extra for tuning from the Factory.

[racer7x]

Here is some info I found, on the tech page ...near the bottom are the rivets.
http://www.vmax4.com/tech10.htm

[YAMMIEGOD 3:16]

THE 8BU,s ARE 48.7 EMTIE. YOU HAVE THE QUADS ON THIS OR STOCK EXHAUST. I BELIEVE YOUR CORRECT AROUND 52 GRAMS LOADED. KEEP IN MIND, THIS IS THE PSI QUAD SET-UP ONLY TO LOAD 8BU. JUST A REMINER. I ALWAYS USED THE 5.0.!! A 800 STOCK VMAX 4 HAD MORE WEIGHT THAN 48.7. I BELIEVE 13.9 BACK. 13.3 TIP. THIS IS STOCK. ! 3:16 (tony)

[Skinner]

Josh
Pulled apart a 8BU clutch, stock
Weighed on a gram scale

Weight alone = 49.7 grams
13.9 mm rivet = 3.5 grams
17.2mm rivet = 4.2 grams

Total weight = 57.4 grams

Made sure the weight was clean, scale is calibrated

[jminor]

Holy shit. I've only got 48.7 weights in there now I don't think I can get that much weight on those heavy hitters!

[jminor]

3:16 I've got the quads as well.

[YAMMIEGOD 3:16]

OPPS. STOCK 8BU-00 WERE 17.2 INNER 13.9 TIP. THIS WAS STOCK IN 800. I WAS THINKING SRX !! ANYWAYS YOU WILL OVER REV AS WE SPEAK WITH THOSE HEAVY HITTERS UNLESS YOU CAN LOAD THEM !! 3:16 (tony)
dude, you have quads on this !!

[YAMMIEGOD 3:16]

DUDE, LOOK, LOAD THE 8BU-00 WITH THE 5.0 RIVET IN BOTH HOLES WITH THE QUADS. RUN THE 49-43 HELIX @ 1-9 OR 100 DEGREE TWIST. USE SILVER SECONDARY SPRING. ITS YOUR CHOICE ON WHAT PRIMARY SPRING TO USE, BUT DON,T RUN UNDER A 4500 ENGAGEMENT. YOU WILL PUT ALL OTHER SET-UPS AWAY AFTER YA RUN THIS. HANG ON !! 3:16 (tony)

[jminor]

I'm game and will let you know. Thanks 3:16. I have to look at what I've got there now. It's your set-up for a stock 800.Do you know off hand? I know its a hauck blue, I think that's the right helix I've got and I'm not sure of the rivots and secondary spring. Any clue from memory?

[YAMMIEGOD 3:16]

MY STOCK 800 SET-UP WAS STOCK WEIGHTS WITH STOCK RIVETS UNCHANGED. RPM @ 8350. USE HAUCK BLUE PRIMARY AND 49-43 HELIX @ 1-6 OR 70 DEGREE. THIS IS STOCK PIPE SETUP. WAY BEETER THAN STOCK. ACTUALLY THE BEST SET-UP FOR A STOCK 800 OUT THERE. NOW WHEN YA GO TO QUADS, YOU MUST ADD WEIGHT TO PRIMARY, SO YA LOAD 8BU-00, RIGHT UP, ALSO YOU MUST ADD SECONDARY TWIST BECAUSE YOU NOW NEED TO RUN AT 8650-8800 AREA. ALSO KEEP IN MIND YOUR ADDING ALOT MORE WEIGHT TO PRIMARY SO THAT WILL DROP RPM, THIS IS WHY YA NEED TO GO UP ALOT ON SECONDARY TWIST. there really is not a huge defferece in these set-ups except adding weight to primary and secondary twist for added hp gain 3:16 (tony)

[jminor]

what are the stock rivots and the secondary spring colour?I'm just wondering so I know what to get/change.I have a silver secondary that I tried in my viper, same one as you call for in your setup?

[YAMMIEGOD 3:16]

DAVE (skinner) POSTED STOCK RIVETS THAT CAME IN STOCK 800 UP ABOVE (17.2 13.9) THE SILVER SECONDARY SPRING IS SILVER MARKED AND IS STOCK SPRING IN 800 SECONDARY !! 3:16 (tony)

[Skinner]

The only way to really know its to weigh them. Ya never know who had their mitts in em unless you bought it new.
Recomendation:
Take the weights out and see how close they are to the weights I posted above. If they are off, drilll them out and go to your dealer and get

13.9 rivets: Yamaha part #90261-06034-00 (3.5 grams outer hole )
17.2 rivets: Yamaha part # 90261-06033-00 (4.2 grams inner hole )
This will get ya back to stock
I ran 17.2 mm rivets in both holes last year (piped), that also worked well

You should be able to load those heavy hitters more than stock 8Bu I would think. Just bought a set of T-weights from Pat Hauck for my Pro stocker, Pat told me to run them in the stocker as well (BONE STOCK)
and recommended 65 grams per weight. I personally think that is a little heavy, will try it this winter. Pats been runnin V-4's along time, don't hurt to check it out. I might have an extra orange primary spring if your using this set-up for speed runs

Happy Thanksgiving
Skinner

[jminor]

skinner I've got the blue spring I should be good with that for now. Maybe I have to order heavier bolts for the weights because looking at the kit I got theres nothing there to put me to the mid 50's. I'll try the 8bu setup and work on the heavy hitters. Mine is also piped. I BOUGHT THE LAST NEW SET FROM PSI!!!!!:bum:

[Master of Faster]

You can load those HH's right up if you decide to use them, I'm at about 60grams in my RX-1 with the 48gram base weights with plenty of room to move.

But if you end up running the 8BU's and don't need those HH's let me know, I'll give em a good home.

[jminor]

If I don't use them in the V4 I'll be putting them in my RX-1!!!

[Master of Faster]

OK, just thought I'd run that by ya. They're a good weight, I'm lookin for another set to try in a Viper.

[VMAX535]

How's 49/43 do you guy's use Hauck, Dalton, Bender, Yamaha???? Is one better then the other?

Thanks,

Dan

[jminor]

I ran them in my wifes viper and I reccomend it for sure. My friends bone stock vs mine w heavy hitters in a radared 1000' 91.7 stock 96.6 w heavy hitters!!

I run a Dalton in one and a Bender in my other V4, no difference except the Dalton is gold in color.
