Hey all! It’s been quite some time since posting but now that it’s that time of year I figured I’d pop in and say hello and a big thank you!
Reading about clutch mods etc. I installed a 1mm shim in the Bruin last season. Seems just about every time I come on here someone is talking about machined clutches. Long story short I contacted Coop45 a few weeks back and ordered a new sheave.
I came a couple days ago and installed it today. I didn’t do an A/B comparison between it and the shim unfortunately. I didn’t get the low end I was expecting from all the reading but I figure it’s due to lack of ponies. I’m thinking valves need adjusting as well. Certainly wouldn’t hurt.
No wheelies… but I did notice it has pretty good take off and gets up to speed rather quickly. Also notice, as mentioned by others, it doesn’t rev as high without the shim. Also takes less throttle. Unfortunately I didn’t get to try it on any steep hills.
Arnie does awesome work! Very good communication and quick returning emals. He received the new sheave on a Thursday and was going to send it on Friday but couldn’t get hold me for my phone number. Would have had it sooner had I checked my email sooner. :o( All in all I still received it much earlier than expected given I’m in Canada.
Looking forward to getting on the trails once they’ve gotten a chance to dry and see what it’ll do with hills. Not sure whether I’ll reinstall the shim but it certainly runs nicely for an eggbeater.
