Buy this. Buy it now. Spend the money, and buy it. Installed the kit and followed the instructions super easy. Rode it the next morning and WOW. Ridiculous difference. My bike was great before, never bogged or any issues like that but now i can tell that it’s running at its absolute best. Buy this buy this buy this buy this buy this!!!!!!!!

I was skeptical dropping 75 bucks for a needle, main jet, and plastic o-ring. But WOW it was worth it. Rebuilt a bike and got it running but never very good. Turns out the carb was just waaay out of step. Took a chance on the JD Jetting (read lots of good reviews so thanks joe public for the reviews.) This kit made a huge and immediate different. Crf250R fires up quick and idled smooth with no bog. I did the accelerator upgrade also. I would also say you need to get that slack out of the pump spring before you put on the o-ring (2006 and earlier only). Very happy with this product!!
