my buddy has a trx450, pipe, airbox and jetted. when he gets into the throttle the bike has a short bogg before it takes off. This is the only issue with the bike. Other than that the bike is quick and great.
thanks for the help

 

Most likely, his jettin isn't quite perfect. This is a pumper carb, so adjusting that may have an effect as well. He needs to first determine if it is getting to much fuel off the bottom or to little.

Read this to get an idea of what effects your carb right off of idle. Pilot jet, throtle valve, maybe try raising and lowering the needle, mabe a different shaped needle, and adjust the pumper delivery both up and down (????). Remember, only do one thing at a time!:

Do you mean when you mash the throttle wide open it bogs? Mine did that too. When I put my pipe on I didn't jet it correctly and it would do that.

 

Yes, only when you mash the throttle does it do this. What do suggest we start with? Main jet? Isnt the main jet for 3/4 to wide open throttle?
thanks guys

 

Someone will chime in and help you. I did it wrong, so i paid to have it done correctly. I don't remember what they put in. But I also run in Colorado, rarely below 7000ft.

 

mine was doing the same thing. i bought it with a pipe, k&n and a jet kit already on it. i got it in the shop right now the guy says he dont think it was jetted right.
