After 300 miles i decided my KLX needs a little bit
more kick...so i want to upgrade IF:

do you guys know if i'll loose my warranty if i
change anything on the bike, thinks like the
exhaust (FMF pipe) or jetting?

If so i'd rather go with stock...

 

i have done quite a bit of custom stuff and also had quite a bit of warranty work done, unfortunately .

 

if your that worried about it just change the gearing to 13-45.... that will help alot.... and not change any major stuff.

 

Just the 13t sprocket made a major difference for me, I have changed bars, barkbusters, airbox snorkel, will do the crankcase breather as soon as I find some pipe that will slide on. I have a fairly good relationship with my dealer and asked wether the crankcase breather will void warranty said no, jetting or pipe won't either (that according to my dealer) I think a lot depends on your dealer and what mood there in at the time.

Cheers

If you modify your bike you could void your warranty-by the letter of the law/warranty rules. but talk to your dealer- Before I left the show room my dealer had told me about all the free mods- to wake the bike up.And said they would be fine with providing warranty service with that stuff done. The 13t counter shaft make a nice differance.

 

When the question of mods versus warranty come up, there are a couple of things to keep in mind. I bet that if you throw on a 290/300/331 kit its probably going to void any warranty.However a full exhaust system or jetting or other smaller mods will probably not void anything. I can't imagine any dealer turning away work because you did a few changes to your bike, and if you have a great dealer like I do, they will always take care of you.
