Hi all. My bike sounds scary. I think it was from the CCT and adjust it but the problem still exist. What you think can be, valves, camshafts ot crankshaft bearings. Thanks

It sounds like the cam chain timing is out by one tooth.

Sounds like it is not running on all four cylinders

Holy Crap!
Well, time for a 1287 build!!

So everything is send for repair and waiting the gaskets. The reason of the mess is a broken valve after bad clearance or didn't make it. Two of the valves are broken and makes the wholes in the piston. When the parts came back I will send photos of the progress.

Gaskets delivered. Head gasket, valve cover gasket and spark plug o rings. Now waiting for the head

 

[ninjayorkie]

Are you going to change the piston rod on that one in case it's bent or twisted? Just a thought that's all.

The guy which works of the bike will test it and if there is any curves or something else it will be changed
