I was changing out rivits today and found these on one of my SRXs. Looks like some decent mid range added.

THAT TRICK ABOUT AS OLD AS SNOWMOBILES THEMSELVES. lol. BRENT, YOU STILL WANT THAT HELIX ? 3:16 (yammie tony)

Tony, Payment was sent Monday. Using it on an SRX with these ramps.

OK, THANKS BUD. 54-46 DALTON. YOU ADD A NOTE WITH YOUR ADDRESS ? 3:16 (yammie tony)

looks like the 13.9mm(3.6 gram)rivet in the heel,why in the hell would they have welded it vs putting a 4.5 in there? waisted good weights if you ask me..now how you supost to properly tune that now,gring the weld off then weigh it up.

That's why I posted the photo - I haven't done this for years and mine would be a lot of trial and error. I always preferred brazing myself. These weights were done not that long ago and I guarantee the guy who did this knows what he was doing - I don't think many would argue with his reputation in powersports. He did these weights to match up with his engine work. Bottom line, these suckers work great. I use the rivits to fine tune.

I DON,T BELIEVE THOSE WEIGHTS WERE RUINED AT ALL. THATS ACTUALLY A GREAT TRICK THAT DISTRIBUTES WEIGHT THROUGHTOUT THE WHOLE POWER CURVE. ONLY THING YOU BETTER HAVE A GOOD SCALE TO WAY THSES WHEN YA DO THIS. 3:16 (yammie tony)

never seen that before,, thats the thing you'll need a good scale to fine tune from there on out.

[YAMMIEGOD 3:16]

NOWAY YOU CAN GET THESE RIGHT WITHOUT A GRAM SCALE. BUT WHEN THEIR CLOSE, THEY WORK NICE. 3:16 (yammie tony)

Thats a great way to add weight to them, The ones ive seen though are usually welded more to the tip, And as far as ruining the weight, How does that ruin it,empty them, weld them,weigh and adjust them by grinding,and now you have a heavier base weight to add rivets to, i dont see the negative in that. Just my opinion though, not trying to step on anyones toes. Peace out

The heat over time would weak'en the steel i would think,BOOM!!! @8,000!! not for me..

Where the weight is added will generally effect the way the engine responds to the clutching. If you add to the end, you should see more emphasis to the top end speed; to the base, you should see more off-the-line performance; to the middle, better hole-shot area. Keep in mind though, this all has to be in balance with the whole range of the power delivery set up and what the engine will support for load. So, just slapping a weld on and grinding to balance may not work.

Welding can create fractures through bittleness of the metal from the heat. It can also cause warpage, though, it would be hard to detect in the small amount of weld you see in the weights pictured. In applications like this, there is a danger of burn off of the base metal (original weight) especially close to the edges. The steel will not be weakened if properly welded. The weights can be heated or "pinged" for stress relief and there should be no failure.

The weights in the photos show a very good job and were probably done with a MIG (I can show you poor examples of welds but I'd be too ashamed of myself). Personally, I preferred brazing on jobs like these as my control and finish was superior to arc welds.

Yeah, totally understand that, it all depends on the operator of the welder. Didnt really think of it weakening the metal if done wrong,that is a very good point. But still a great mod if done right.
