Hi,
thanks for taking the time to read this and hopefully offer some suggestions, experience and advice.
It's a '72 Honda CL350 that I've had for about a month or so now. It's in good shape but not running. The PO had rebuilt most of the engine - he had the cylinders honed with new Bore Tech pistons,rings and valves (valve seats were lapped) - he had purchased a Triumph and never got around to getting this going again when he sold it.
Since I've had it I discovered that the PO had not set the timing of cam-crank shaft properly nor the valve timing.
I did a combustion test I had the carbs off, as well as the header/muffler. I did the test five times, all cold (the bike is not running) and pretty much got the same results each time with both cylinders. 1st kick - 45-50 psi, 2nd kick - 60 psi, 3rd kick - 90 psi, 4th and 5th kick both cylinders topped out at 120 psi.
I'm hoping that the only reason it's not getting up as high as it should be is due to the carbs & muffler being off and it being cold - my fingers are crossed that I don't have to tear it apart.
Any help would be appreciated.
Thanks Fellas!
