morning GNASHER...thinking the same on the rings :thumbup ...bikes been stored for 2 ish years in a garden shed,first job i did when i got it home was to squirt some derv/paraffin down the bores and turned it over on the crank a couple of times then left it, think i need to source a radiator and run it up to temp and leave it running for a while. lapping the valves is another great suggestion but i dont really want to spend too much on this engine , i`ll do a valve check, oil/filter and new plugs, plumb in a rad and run it and then do another compression test...if all`s good and i see some improvement i`ll do the swap, could be in there some time while i sort the original engine,if it performs well i`ll lap the valves when i`ve swapped back and sell it on...
going back to my "stuttering thread" a while after lapping the valves and doing a compression test (135 psi ) i had it on the dyno, 1 or 2 bhp down on claimed power when new...makes me question Haynes figures...
