Hey all

Im a newbie so cut me a little slack ... iv just rebuilt the top end on my 96 dtr it ran a little boggy when i first started it and the overflow pipe at the bottom of the carb was pissing out petty. so i took the carb to bits and gave it a dam good clean all looked ok so i refitted the carb and ran it again ...... the leak stopped but after a few minutes of riding it started to bog down when i went under 3 thousand revs and this gradually got worse.... it just about got me home after a few stop starts.

My mate told me that i forgot to block the 2 stroke pipe.... because i took the oil pump off and i am pre mixing...now it is running really crisp at the slightest touch of the throttle but the overflow is gushing fuel again yet it runs gr8....its got me really confused...any suggestions you guys and gals have will be more than welcome.

love the site btw

Hi

Sounds like the float valve is faulty or not shutting off the fuel when the float bowl is full - you need to dismantle the carb and check the valve operation and float height settings.

Good luck

:D
