Should I change Sprocket bolts?

12 posts in this topic

I have an '07 450, and am changing the sprocket, should I take this time to put on new bolts? My buddy who has the same bike sheared his bolts off, and swears that the OEM bolts are weak and need to be changed. True? Also should I use Lock-Tight when putting the sprocket back on?

bolts usually shear when they become loose, your originals should be fine, properly torqued and loctited. don't use the allen head to final tighten, tighten w/ the nut. allen heads strip out too easy. the bolt will stay as you tighten the nut.

While replacing them might be cheap insurance, its not needed. Just torque them in a criss-cross pattern and use plenty of red loc-tite. And be sure to recheck them after the first ride.

Like the guys above have stated the sprocket bolts are plenty strong from the factory and won't fail UNLESS they are OVER TIGHTENED....Use a good torque wrench and BLUE lock tite (Red is a bit aggressive for bolts that might be removed again)

I've got over 160 hours on my 04 race bike and close to 130 on my 06' race bike now - stock sprocket bolts and at least 10 sprockets per bike!

I've always done blue loc-tite in a criss-cross pattern and have never once had any issue at all.

Also, if they don`t want to brake loose, use hot air gun and make sure to clean the threads before putting it all back together using loctite as mentioned allready.

I've sheared some heads off my sprocket bolts. I blame it on rushing through those over-tired late nights trying to get the bike ready for the morning. I think the bolts are fine though!

I've never, ever used Loctite on my sprocket bolts.

And I've never had them come loose.

Come to think of it, I don't use Loctite on ANY of my fasteners, and I don't have a problem with stuff falling off.

Probably just jinxed myself huh?

Based on my experience, I don't think so.

Yup, I'd say you're screwed now.:thinking:
