49T Evo Ring Gear install
#11
Maybe I missed something here, but I think he wants to replace the starter ring gear, not change the primary gearing of the bike. I replaced my ring gear a few times after it got chewed up. Just use a hand grinder on the rivets, then knock them out. I used bolts, nuts, and loctite as mentioned about. It's been going on 10 years and nothing has worked loose yet. Alot easier than trying to rivet it again.

[QUOTE=grbrown;5789370]Steve,
Assuming your bike has the stock 34T/46T primary, your primary gearing is 1.353:1, so fitting a 49T will change that to 1.441:1.
If instead you can fit a 32T compensator sprocket, the gearing 32T/46T will be 1.438:1, which is as close the same as matters! (99.8%)So are there no 32T compensating sprockets available?
The last I checked a 32T was not available because a chain was not available without doing a half link. Thus, the 49T option.

From the responces I've gotten here it doesn't sound like many people have tried this, but I have gotten enough info to have a pretty good idea as to how the ring gear comes off the clutch basket.

I tried the 30t non compensated front primary gear this spring and it was a nasty sounding thing, I can't imagine that it was doing the crank any good, then I thought about the 30t rear drive gear and a new belt but from what I've heard it is a real pain in the butt to install, so that's why I'm going to do the 49T ring gear it lowers the ratio a good amount and isn't a total pain to install, and it only costs $300.

Sounds like a good plan. Let us know how it works.

It's not the starter ring gear, it's the primary chain gear that is on the clutch basket, that he is changing. The price on website is 480, you can get a whole new clutch basket with the 49 gear that weighs 2lbs less for 660 , both include new chains.
