Honda Deceleration Pop 06 TRX250EX

Recommended Posts

I know that the CA emissions are jacking up performance, even stock. I purchased a used 06 trx250ex, have put on a new stock carb since previous owner let it sit and gum up. Have put in Dyno Jet needle, uni filter with box lid on, have stock 95 main. stock pilot-maybe problem, and a big gun rev box since the stock cdi would crap out at upper rpm range.

Question, Tech @ Temecula Motorsports says start with air/fuel @ 3 turns-done . Still pops. Next he said pilot jet may be too small. Third step is Tight intake.

Anyone else had these probs with a CARB trx250ex and does this sound like the logical progression.

I know popping is lean jetting and he mentioned that it was related to the pilot circuit. Don't want a lean mixture, leads to valve damage:banghead:

Thanks,

Puckerbush
