Hi there,
I'm pretty stumped on this one, long story short a few months ago my fazer decided life was too much and gave up the ghost. Ended up with new downpipes, a replacement cylinder head and a rebuild project.
The new cylinder head is bolted down and I'm completely stuck at the cam timing. Everytime I get the engine timed up, it just won't turn, it feels completely locked, I dared to give it a little more pressure once and it slipped off the bottom cam sprocket :o
Both guides are in and the cam chain tensioner is in, I've looked at various videos on how to do it on thundercat engines and have read up on the various threads here related to the issue, I have no idea what's going wrong.
I transferred the shims from my old head into the replacement cylinder head as I planned to use my old cams as they were in better condition, but I've tried with both sets of cams with the same problem.
For what its worth, the engine turns fine without the cams in, I have not replaced the camchain (30,000 miles) as I simply don't have the funds at the moment, however I'd say it has a good 10-20k left in it judging by the tensioner position when it came out and how tight the cam chain was.
My next plan is to move onto the unlikely stuff, e.g try it without the guides to see if it's getting caught on them, and try smaller shims, it's worth noting that all the buckets push down freely.
Any ideas? :\
