Honda 07 trx450r jetting?

Question

I just bought a 07 450r and want to put on intake and exhaust. Does anyone know what size jet I should use at 5000ft after I put on the intake and exhaust?

Answer 1

depends on what you put on....

best way to tell.. is run the bike & check the plugs..

you can tell if its lean/ rich by the color & deposits on the plug...

it may just be a case of adjusting the carbie...  but if not then you will need a selection of jets ..or  try it & then go get the jets..
