Lifters

[SoreandSorry]

Ive finished rebuilding the engine and im embarrassed to say that ive never had to set adjustable rods.

This is what I did:

Assembled the motor and on TDC for that cylinder I slowly wound the rods out little by little until the lifter bottomed out. Then backed them off .100". I did this for all the valves but noticed that one of them springs back and the other three dont. This is what has me confused... are they damaged? I dont want to fire the motor till im sure.

The whole valve train is self adjusting. Hydraulic roller lifters and solid rockers, nothing to adjust. Not that i'm aware of anyway.

Did you follow the procedure in the service manual?

I had to pull the rocker set off the front cylinder to get the cams to align correctly. I took the cover off (4 bolts), removed the 4 big bolts, loosened the 3 smaller bolts, then knocked the pivot pins out of the rockers. That gave me enough play to get the cams in correctly.

Manual doesnt really cover much simply because they consider on a stock buell there is nothing to adjust. I put adjustables in because I lifted the head height to give less compression. Im not worried about the setting of the length, just the fact that one out of four doesnt seem to have that spring action.

When in doubt, change it out.

Sore;
My apologies, did not realize the engine was not stock.

I've got nothing. Mine's bone stock as far as that goes.



When you adjusted the rods, you mentioned you adjusted the cylinder to TDC... did you try spinning the motor another revolution and try re adjusting? Possible you had it at TDC on the exhaust stroke? Obviously you are smarter at this then I am, I wouldn't even know where to start doing what you are doing. [up]

Mate theres no need to apologize [smirk] It was on TDC firing stroke. I tried connecting a battery and turning it over by starter motor.... still the same.

My neighbor popped in and said dont worry about it till it runs for a minute and has a chance to pump up with oil pressure. Im hoping its just an air bubble. So im gonna cut the header about 8 inches long (like drag headers) and start it that way. Once the motor is proven ill move onto the header.

Then maybe mount the turbo
