Hey guys, Any of you have klr650 friends? I wanted to let you know, I had a 99 Kawasaki KLR650, and I now have a 2008 DR650SE. I found my old dynojet kit for my KLR650. I took the carb off my DR650SE and pulled the factory needle out. The factory KLR650 needle with the stock DR650 white plastic spacer is very simular to the Dr650 dynojet needle when the dynojet needle is set on the 3rd notch! The stock jet in my DR650 is a 140 and the stock jet in the KLR650 is a 148. So I installed the stock KLR650 parts in my DR650 carb and WOW!!! It runs perfect!! My setup is stock exhaust, snorkle out of the air box,screen still in place, header weld ground out,KLR650 stock jet and needle, slide drilled, and wow!! NO poping or backfiring whatsoever!!! It now will pull the front tire in 1st and 2nd gear with the throttle. You may be able to get this stuff free!!!! Good luck, Jay.
