Help? I modified a 400ex to a 465 stroker with opened airbox+WB r4+powerbomb header

[spinka]

400ex-
I got a Trinity 465 stroker with a outerwear airbox lid, K+N airfilter and a WB R4 with FMF powerbomb header..Im running 110 octane fuel.. When I hit the throttle real fast it stalls out and it also has no top end it revs out real fast and does not accelerate??Do I need a new rev box or is it just jetting?? Trinity put stock jetting in it??How and the hell do I jet this thing any Ideas???Please help?

Sounds like you arent getting enough gas!! From what Ive heard about the Trinity 465, dont expect much!!

if there is no porting done and it is stock valves, and a stock carb 45 pilot jet and a 160 main should do you OK. But it is a trinity motor so it might be a bit different than mine
