Thanks guys


OK, tonights jobs were......Stripped and cleaned the petrol cap, removed the broken up cork gasket from inside it. Noticed that the exhaust was replaced without the gaskets, (they were still in the packet!) so refitted them. Next, I'm gonna re check the carbs and make sure that they are at the correct settings.

I know how you feel (reasons x many in my posts of recent past!).

Could you have an airlock forming in your fuel tank after running the engine for a few minutes - mine certainly gets a lack of atmos pressure in there and I loosen the cap occasionally; there is always a hiss of air going into there.

Might be worth reading back over earlier threads about running problems for the XT/TT - this has helped me a lot to get new angles on a problem.

Alternatively or as well as, review what has changed - what has caused this to start now? Summarise and recap the issues in this thread - I have found that over time I have lost sight of the obvious!! :rolleyes2:

I hope this helps, if only a bit!

Dave

How you getting along Basspete?

Check the valve clearances.
If there is no clearance when they are cold, then after about 3 minutes they will expand sufficiently to hold the valves open and stop the engine due to lack of compression.

Hi folks,

Thanks for your replies, I ve not been near the bike for a few days, busy with other stuff. I took the carbs off and checked all the settings, I'll check the valve clearances again today.

My relationship with my XT is deteriorating fast! Valves certainly make most sense, as the top end was the thing that was changed during the overhall.

Here goes again!

Pete
