    Default Aaen Quads

    I see this is the first post here.
    Many members on this site are big fans of the PSI quad pipes for the Big Max. I have no problem with this fact. I just want people to be well informed before they go searching for a pipe that's getting hard to find that might not be everything they've dreamed of. I've got a set of Aaen quads on my 95 800 that were installed by the dealer in late 94. I bought the sled in 01 with about 6500 km on it. The engine explodes at 6000 rpms and pulls like a freight train until 9000 rpms. The power is always on tap with a squeeze of the throttle with clutching being the only changing factor. An e-mail to Aaen informed me that the shift out speed should be at 8750 rpm. Mine shows 8800 on my tach. They also recommend engagement at 4500 rpms. Obviously individual clutching setups for personal applications will change things accordingly. Aaen is very helpful about answering questions. Also remember a little known fact, Olaf Aaen started out as a factory Yamaha pipe builder/tuner. He use to build their factory race pipes!
    I'm very happy with mine and not looking for a different set.

    I agree on the Aaen pipes. I had a set of trail pipes and they worked very well. I have a high rpm version and they perform great also.

    On my big bore 880 ( inline - 4's old one) I ran aaens on the trail, sled would run 112 mph with stock gearing and 94 oct. in 1000'. 5.69 seconds in 500' with 20/40 gearinging at 89 mph with a pro action skid pulled down at 9000 - 9100 rpm. The same sled would run 5.39 seconds @ 97 mph @ tony specific rpm 8750 with psi's.

    Wow..Big difference...I know I have a time slip to go with this..When I had a 800 stock engine with PSI quads I ran a 5.70 @ 89 mph in 500' at Marilla NY...It seems the PSI's realy make that BB work,very intresting..

    Can you guys confirm these pipes run at 9000 RPM? Trying to decide if I can used them without a 180 box

    The ones i'm looking at have stingers so they are Trail I think?

    Mike, Aaeen pipes run at a max. 9000 rpm with a ported motor, then drop off hard if reved beyond this. If motor is stock, clutch for 8800 rpm the HP curve is pretty flat between 8750 and 9000 rpm this will give you a little room. Std 8BU box and 90* firing works great with these pipes.

    Thanks Dan ( that is right? ) I bought them today the guy said they were F3 cut pipes and were supposed to be 9500 pipes he called Aaen to confirm this. He said they come on like hell fire at 6000 and pull real hard to 9000+

    I'm on a welded 750 crank, I read not to get over 9100, any thoughts on that? I'm thinking to clutch for 9000ish and forget the extra 500 RPM. I've got 89a, 8ax & 8bu boxes to pick from, I was thinking 8bu Primary right now is 89A10 weights-17.2 rivet in base 13.9 in tip and a Yamaha W-W-W

    Can you lend any help on clutching or should I try to call Aaen?

    Thanks
