Today was the day, after a couple of weeks waiting for parts it all came in last thursday. It took me two evenings to put it all back together and today i finally started it. There is only one thing that doesn't seem wright.
When the engine is running idle everything goes well butt when i rev it up a little to some 4000rpm and i close the throttle, the rpm's go down very slow. Almost like the throttle cable is stuck but it's not.
Also while riding i noticed that when i pull the clutch, the rpm's go up. I changed the idle a couple of times and that did help but after a while the same thing happened.


Before i fitted ivans full monty i did not have this problem.
Yes i've balanced the carbs an adjusted the tps.


Can anyone point me in a direction to look at.

Sounds like an air leak somewhere.

Thank's, i'll spray some brake cleaner on the inlet rubbers to check if somethings sucking up false air.

Can it be that there is something blocking the holes i drilled when fitting ivan's jetkit?
