here is what i have investigated further sounds like my prob for sure what do you think
.Check pressure sounds like oil pressure is taking time to build and may not be getting there.the tripple sprocket bolt (Oil light flikkers and bike will over heat)but check that to, takes 20 minutes.Almost forgot check the o ring in the oil pump and bi pass valve but everything on the right side has to come off.
OR THIS ONE
They wanted to pull my oil pump and water pump because I had low oil pressure and overheating when I told them to check the sprocket bolt first.They had no idea the bolt capped the oil passage to the heads and that the clapping force drove the water pump.After I threw a fit they found it was the sprocket bolt and took 20 minutes to fix.
