also today I noticed the wax from the timing mechanism had melted and collected at the bottom of the cover the size of a finger nail. The Evo guy at the dealership told me it could be this and this alone because when we took the cover off without following the manual it could have jarred the mechanixm enough to cause the problems I am describing. Today it ran 300 miles after starting with little effort and except for the lull in power after turning accelarator and two backfires it was in good condition for a motor 600 miles out from a top end job.
The lag could also be the VOES.

OK,, so far I have confirmed that the timing mech. is working correctly and that the carb and accessories are not taking in air. Will the cam end towards the middle of bike fall when and if I remove the cover on the other end of the cam and the oil seal holding the cam in place or is it stationary when the cover is off and it is sitting on the drive gear? If I can do this then I can get to the breather gear which I feel is the problem due to the excessive oil from breather. It can be repositioned without the cam moving. Please give good advice.

Let me restate, if you have never taken the nose cone off then your timing and breather should be ok. Oil coming from the breather is quite normal in the V-Twin EVO engine. Excessive oil could be caused by too much oil in the oil bag, excessive blowby in the engine or a bad umbrella valve in the rocker boxes as the most common causes. First do a compression test with the engine warm and the throttle held wide open. Then do a leak down test. This will help tell you if the problem is mechanical. Hope this helps.

It occurred when I did the top end. I was reluctant to open the timing mechanism so I put the cover and cam back in without disassembly as instructed by manual. It is supposed to rain tomorrow so off the road and it will be done in the am. Thanks guys.
