Chain hitting frame … cannot figure it out ?

Bennihanna · Nov 25, 2024

Just got this bike 1987 very clean, 9000 miles. EM doohickey done and tested - good. New tires , chain guard removed to prevent rubbing. Brand new sprocket front and rear, brand new o ring chain, oiled, chain tension set properly (bike is lowered two inches so ive tried several different chain tensuobs between touching the black guard and about 1/4 inch away) i weigh about 130 lbs…. It looks like my master link is touching the frame on the bottom side as it exits the front sprocket ? It’s almost as if my master link posts are too long ? The original chain was a rivet chain, do i need to switch back to that? Ant ideas ? Allignment has been checked with a strsight edge. Looks to be some wiggle on top of chain entry into front sprocket. Do i need a new chain guide ? Seems to be plenty of meat left of it

By the way it does not happen sitting still in neutral at all and everything has been tightened to factory torque spec

You need to get the proper masterlink for your chain. Manufacturers and even models are not interchangeable.
Photos might help.

Like I said it is a brand new 520 106 link chain with the included master link… is there different ones I can get or should I grind this one a bit and report back?

Niche brand o ring chain

Is it touching the frame on the bottom or the bolt that holds the rear sub-frame to the main frame above the swing arm? If too long a bolt is installed at the sub-frame it will touch the master link.

Below foot peg definitely ! That bolt I’m aware of and it is stock!

Just turned the master link around the other way. I’ll ride in the morning and see if it’s hitting the case but seems that may have actually fixed it

And, what size front and rear sprockets are you running?

pdwestman · Nov 26, 2024

Most Front sprockets for the KLR650 have steps on each side. The Shorter & Smaller diameter Step is supposed to be installed Towards the engine.
Some real Cheap engine sprockets just use a collection of spacer shims.

If the chain is contacting the Cross-Tube Below the chain, then your bike is missing the rubber slider that attaches to the lower rear engine mount bolt and curves around the cross-pipe.
