TE250 -08 MANIFOLD INTAKE part 8000B0369

Hello,
I have experienced that the mainfold is not seated securely on the carburator and there is occasionally a leak between the cylinder head and carb and of course the bike is running really bad.
I refitted the clamp but I feel something is not correct so do you guys think the mainfold is warned out or do you have any other tips or trix?
When I refit it the bike runs perfectly until it loosense again so there are no leakage in the mainfold as such.
They are expensive
Any tips?

Isn't the 08 FI with a throttle body?

On mine (09), it's a bit awkward to get the clamp to sit correctly so it's secure. Have you tried lossening the top rear sub-frame screws and removing the bottom screws? Then you can move things around to get them seated correctly.

Hello,
You mean to kind of lift the back-frame to be able to reach better to fit the mainfold and clamp?
No I have not done this but it sould like a great tip, will test later in the evening!
Thanks!

Just try it and see, it lets you move things around a bit.
