[Fixed] Will not rev past 8k

[reddave101]

After you have tried the things unfazed has suggested, try looking at your clutch. Open up the clutch cover and look at the torques for the outer pressure plate cover and also the see if the springs have worn and gone soft. You can also check on the clutch plates and steel pressure plates to check for blueing? Just another thought as the engine will clearly go past 8k when clutch is in but when the clutch is released it bogs down, maybe clutch isn't engaging properly to get the torque needed. You may also check the crank case breather? Now and again I kept getting the slight bog down but wasn't all the time, after a few investigations I did notice the crankcase breather was filling with a creamy sludge and was filling into my air box. A simple and free alteration soon cured this and now get no bog downs and actually get better acceleration and higher revs, think I've actually hit just over 14k.
