Hi Guys, looking for some help trying to help a mate work out a rattle in his Road King. The motor was taken to a Stage 3 103 about 20000 k's ago, he's just changed barrels and heads again, thinking it was a piston problem, no good. When he starts it after a couplke of weeks it has a pretty bad rattle, that almost sounds to me like it may be losing oil in the top end, it doesn't really go away. Has anyone experienced something like this before or got any suggestions to look at. Could it be something to do with the Pressure relief
Thanks
