Top end rebuild

[fastbysuzuki]

Hi had a small oil leak on the base gasket it was bugging me so off came the head and barrels, the bike has 40,000 miles on the clock so I thought whilst ime here fit new rings, lap the valves, new valve seals, Oem head gasket (MLS), base gasket, new rubber parts etc. Skimmed head and cylinder face, honed bores
Anyway I have just done a 50 mile test run everything seems ok so I thought whilst it's warm do a compession test I got 150 psi on all four cylinders was wondering how that these compare to anyone who has done something similar with a 40,000 bike?

150 psi is very good. It will get even better as the rings seat. Good job.

...150 psi on all four cylinders...a 40,000 (mile) bike

Now you're just bragging!

Make sure you pull the valve cover & re-torque the head now that you have heat cycled the engine.

Took off the cam cover and checked the head fasteners, no movement with torque set at 27 ft lbs.

That sounds low! Is that from the SUZUKI manual for the torque spec????
