ive got an 04 636 with about 25k on it. i have done a valve adjustment and everything was fine.

im noticing that it is loosing power. i first noticed it when i rolled on the throttle in 6th gear and it would bog some unless i gave it a little less and it would pick up some. now im noticing it in second and 3rd gear when i go to clutch it up, both sitting down and standing.
i ran injector cleaner through it hoping it was just **** in them but didnt help.

any thoughts?

 

there is a screen in the fuel pump that may need cleaning , the screen is in the sump part of the pump you have to take the pump apart from the metal base ..

 

good thought.
any other thoughts people?


BUMP...........

 

hmm, for loss of power I would check the cylinders for spark/compression. My 03 636 started slugging really bad last season and it was cause my 4th cylinder was misfiring.
