I have a gen 1 motor, I installed a spacer plate and APE adjustable cam sprockets, only thing different internal from OEM. When degreeing the cams I set to TDC, and set the end marks on the cams to OEM position, then adjusted from there. I am at 105 intake / 106 exhaust. I checked everything 4 times to be sure. I torqued all bolts to OEM spec. I completed build the other day and went to start, it cranked around 2 or 3 revs slowly then died out like it was a battery issue. Battery was slightly low so I put a charger on it and left on when cranking to see if it made a difference, very slight improvement if any. Then thought maybe the battery just lost the deep cells to crank, I replaced battery and no difference. So I took apart the gear cases on the side of the motor to make sure all gears from the starter all the way down to the starter clutch to make sure nothing was binding and all lined up, which they were good so ruled that out. I pulled all 4 plugs and cranked around without stopping this time but it sounds like something is holding it back, was not cranking near fast or free enough. When I torqued down the cam journals it is pretty light foot pounds, is it possible my torque wrench was slightly off and cam journal casings are holding came too tight? Or that top timing chain guide, made that too tight? The top guide just bolts down to metal so I don't you can make that too tight.
I also checked the torque on the OEM timing change tensioner to be safe. I had turned the motor by hand at one point to make sure nothing was hanging up or metal banging, valves..etc.., and it was fine. It seemed somewhat tight but I didn't have much of a reference to go off how easily it should turn. Before I tore down and took motor to TDC I was pretty close already and did not have to move mark much.
Before I tore the bike down, I started the bike and fired right up. I am about to tear back into it to find the problem but thought I would see if anyone came across this before or things to check.
Any thoughts?
