DR650 new tank install problem
 

Maybe someone can give me a clue as the reason for my problem.
I have replaced the standard tank with a 20l Acerbis.
I followed everyone's procedure... i.e. I folded and tied the vacuum hose (in two places),
I installed an inline fuel filter and I can prove plenty of fuel coming through.
I check the small basket filter in the carb inlet and it was clean so I put it back.
The bike runs as usual until I try to accelerate. It behaves as if it's starved of fuel.
I can drive in a 'traffic sedate' manner and not notice anything. But when I try to accelerate a little faster, it stutters until I back off.
If I just accelerate slowly I can still go as fast as I want and at top speed, it still runs smoothly.
But when I ask for some power to get up a hill, it runs rough until I back it off or it gets to the speed I want, then it runs smooth again.

Any ideas? Is it because I have not folded the vacuum hose close enough to the carb?
I'm pretty sure it's not because it's running rich - no backfires - it's as if I am running out of petrol.

Hmm, silly me. Took the seat off and noticed my Airhawk sea elastic strap lying across and sucked into the air intake as a perfect fit across the shape of the intake opening. Took the strap off and problem solved. Phew...

Glad you got it sorted, quick, simple fixes are always the best :)

Not sure what you mean. Mine has a similar problem. I have the acerbis petcock so we plugged the vacuum line... but now wont even start:(

Hi ilse,

Welcome to the HUBB :)

can you be more specific with your problem, what have you changed and what are the symptoms on your DR? is fuel getting to the carb inlet?
