mine ran strong for over a year with 88cc takegawa clutch and then 124+R with takegawa special clutch.

i just put one in my new 50 and im gonna run a grim reaper auto clutch so i have faith in them, but i guess others are not so lucky



have there been reports of clutches going with stock ignition?

so its not really worth the risk ay? lol what about taking a little off the flywheel? like 5 ounces or something


I used to run the 107's without the billet basket (before it was even out) and IRK and had luck on my side I suppose, others were not so lucky. If you don't want it weighing on your mind just get the flywheel lightened, its the less extreme version :)

I have yet to toss a clutch due to an IRK, and my auto 70 spun to 14k RPM. :p I have exploded a cast manual clutch before, but that was on a 107 motor with a normal flywheel and e-start, so it actually had a heavier flywheel setup than a normal 50. It didn't see much for revs (built to be a torquer) but it did see a lot of clutch dumps, feathering, etc, and was trying to haul a 270lb guy around on pavement. I'm convinced it's more the rider than the flywheel that causes them to let go. If you're smooooth... they hold up, if you're a goober, it's a goner.

The Grim Reaper is an awesome clutch, but your tranny might not hold up and careful of the full power 2nd gear shift... it can put you on your a$$.

I never had a problem with my Reaper, but it is NOT a semi auto clutch like your stocker or the others you listed. It is a full-auto and does not 'engage' when holding the shift lever down (or up)... it goes directly into gear and locks up hard. I could chirp the rear tire on my stocker under power shifts... but if you are sitting casual and just going for it, be warned.



As far as the Honda gears, they are good but the Reaper removes a lot of slippage that keeps the tranny alive when it was designed for a 6 year old. Just back off the throttle slightly when shifting for no issues. And it will spin up like a mofo with an IR on the other side of the crank.



If you need the aluminum tool used for installation, let me know I still have one and no use for it.
