Why does my drag bike sputter on the top end?

[Trafficjamz]

Runs great for about half the race then stutters and makes less power.

I suspect it is lean from running the bowl out of fuel.


What do you guys think?

Sounds like a fuel starvation problem, AKA the float bowl is not staying full.

[Trafficjamz]

do you think a fuel pump would help?

Either that or upgrade the petcock to the Aero 125 size or use a manual petcook.

so you didnt take me recommendation i gave to spreemadness when I told him to run a fuel pump on his setup when he was having issues with his 130cc setup after he built it? I noted saying to run a fuel pump for strokers as it runs low on fuel when holding it wot for over 5sec.

My problem was a bent flywheel key

Tjamz bike is crazy as * until top end. I have no idea what it is
