It was me. At 2000 miles the sprocket has some deep hooks on the teeth. That may be from the hihg speed freeway running. Your results may very.[sm=shades.gif]

 

Do you use chain lube?

 

Every ride.

 

i'm almost sure it is because the same thing happened to me. the problem is the 13 t is a lot narrower than the stock 14t. the parts guy suggested using shims. not sure if he's just trying to avoid a return. obvious concerns are misalignment relative to chain and rear sprocket. and if it will dig into the rubber thatlooks like a seal of some sort.

 

yep.. You may want to considergoing back tothe 14 and then bumping up the rear sprocket to 48 or 49 (depending on what your ratio goal is).

The 13 tooth front sprocket also seems to rotate the chain faster around thedrive shaftand some think that leads to faster wear of the chain itself in addition to being a bit noiser.

Your parts guy is on it, if you stick with the 13t you should probably sim it.

Ithought that Kawasaki makes an exact 13t part for the KLX 250s that should not need a shim if you order it from your dealer. Is that what you have or is it after market???

 

it was a kawasaki dealer but the part in question was a renthal?

 

really.... Thats wierd... I know that Kawasaki now has them under their brand specifically for the KLX 250 so no shimming is needed...

I would suggest challenging them on that...

 

Hi. What size chain do I need to buy if I switch to the 14/45 combo? And that just means buying the 45 in back because it comes with a 14 in front, right?

 

hey surf, ihad the dealer throw on a a renthal R3 o-ring chain 520R32-120L with a sunstar 45t rear 5-361945 b4 bringing the bike home new. i've been this route b4 with other bikes and have never regretted it.
