KTM sprocket bolts

I use blue loc-tite thread locking compound and check them often. They can still work loose with the loc-tite.

Loctite, put it on the kickstarter and the shifter too . Engine mount bolts too .. If the engine comes loose and rattles in the frame it will ruin the cases on a KTM as they have no swingarm pivot cones where the swingarm bolt goes through . Ive seen this on more than one or two late models. As for the kickstarter the lever will rattle on the splines and strip away the splines on the shaft.Just prep these bikes good and youll have very little problems.
Using other than serviceable grade thread lock can lead to damaged threads.
I'd stick to the blue, if I were you.

Of course Jaybird is correct however I happen to have an unlimited supply of red loctite. :)
It must work, in over 30 years of racing dirtbikes I've never had a sprocket bolt come loose.
If you do use red apply a little heat to the nut before trying to remove it. Heat softens the loctite. Oh yeah, don't use the red on any of the smaller bolts. Its tough stuff.

Henk, I was using red loc-tite and the bolts were still coming loose. I was using the open end of the wrench to tighten and before I could get it tight enough the wrench would begin to slip. I found that I can work the box end of the wrench over the nut but it takes some finesse, since then with the help of red loc-tite I haven't had another come loose.

I've got red loc-tite but I'll dive out and gran some blue next week. I'm using nylocks at the moment but I've only had the bike a week and after one ride they were loose theymight not have been tight enough to start with. I was riding with a guy on an 01 520 when his hub smashed itself to bits and I realy don't want to go there myself. I'll keep checking them and bang on some new nylocks and blue loc-tite next week. Thanks for all the advice.

LOL - when you guys refer to red loctite ruining threads just exactly which red loctite are you using and do you apply heat before removing? I've used 262, 270 and 271 (all red) in many applications including my sprocket bolts and have never had any issues.
MrLuckey,
I don't know for sure which red loctite # I use. Makes no difference anyway because I never have sprocket bolts come loose. Applying a little heat just softens the loctite and makes the nuts spin right off.
Oh yeah, I've never ruined any threads using loctite either.

The problem is plated bolts. For Loctite to work properly it needs to make contact with ferrous metal. The plating on the bolts prevents this. Loctite help (800-Loctite) line recommends use of Loctite primer 7471 with plated or none ferrous bolts. Plated bolts after use will score and work will better with Loctite. I use the Red Loctite with the 7471 primer and never had problems, even on a severely elongated holes in the hub.
Nylocs, as other metalic locking nuts, are ONE TIME USE ONLY.

Just wanted to add a little. I use the blue loctite, but also apply a small amount at the end of the sprocket bolt that seats inside the sprocket. I don't know when or where I picked this up, but I've never had a problem with loose sprocket bolts. :clue:
