hey guys. I took the top end off the dr650 today it is blowing a lot of smoke on start up. so the head, barrel and piston are out it all looks fine to me apart from some light scratches in the barrel.
my engineer mate tells me it’s more likely the rings then the valve stem seals. I have ordered the seals and will take the head , barrel and piston into him to have a look at.
so it looks like new seals and maby new piston.
only 2 problems on the pull down. ill need a new crank seal (this is very common the net tells me). and more disturbing is the 4 bolts that hold the head on about 1/2 way on each thread looks half striped im not sure I should reuse these. can anyone tell me if that is normal it looks like its the 1st time the head has been off this bike only 30k on the clock.
ill through some photo’s on soon
