Hello everyone
I've recently bought Jackal -01 that has some valve noise on one side when the engine is warmed up.
I hope someone on this forum has faced the same problem and solved it. It only has 12,000 km on the odometer, but of course it's possible that it has been changed earlier at some point. Anyway the bike looks new so the km could be correct.
- The valve clearances has been checked.
- rocker arms and rods has been checked.
- The longitudinal movement of the rocker arm has been checked
- No metal pieces in the oil. Everything what can be seen from bottom looks like new.
It sounds like a metallic click-clack sound. After I have adjusted the valve clearance or removed and installed the rockers, sound can move from one cylinder to the other side. I would assume that the cause must be then some common part/function for both cylinders.
There is a lot of room for wear in the valve adjustments. I expect this means that the valve mechanism parts (rocker arm, rods, valve tappets, camshaft) have not been wear out.
I know that Guzzi'es use to make loud sound but this is excessively loud when warmed up.
After driving season in Finland ends, I will look it little bit deeper. Any hints what I should check first ?
Regards,
Harri
P.S. Sorry about bad English..
