My 450 was running good then I went to ride the next day and when I would try to accelerate fast it bogs. I cant go into high speeds at all, It will barely even go and just sit there and bog down to where it almost dies or does die. I have also noticed that it backfires a lot and spits flames...
I just adjusted the valves and cleaned the carb and now I’m getting a bog when I stab the throttle. I’m running the following set up..
HRC Kit w/HMF slip on
162 main jet
Needle clip 4th down
R&D fuel screw 2 turns out
Wheeler runs great but I can’t seem to get rid of the bog...
I just recently acquired a 2006 trx450er and the guy just put a full aftermarket exhaust on it and because of this you have to slightly give it throttle for the engine to start. He said he believes it needs shimmed. I went out riding for a day and ended up killing the battery trying to get it...
