good afternoon...I submit my problem, I hope some a good soul can help me..the bike is a 05 fs 650..
after the head recon, new valve seals, griding valves in the shop, new bering and head gansket..ecc..ecc
ktm rfs hot cams cam (cutted)
the engine starts only with the red knob hot start, Not Idle and overheats a lot!! ..ai mid/highs revs seems to be fine ... but it overheats and not good smell
seems very lean mixture ..but and then I dismounted to check the phase ..
It all seems ok .. I tried to raise the minimum jet and to raise the needel..but is clear that it is not a carburetion problem
I was thinking about
incorrect valve clearance
by the decompression shaft you can not mount in the wrong the camshaft + -180, but this cam is to another motor maybe change anything?
Head gansket fail..(but oil and h2o are ok)
Only carburation problem
I hope it is not for lack of sealing of the valves ..
To avoid damage I havent insisted to keep the engine running
