XS650 Enthusiast
Hi all, my build is finally coming together. I just fired her up and rode some 10 miles or so. It pops a little from RH side when iddling and at deceleration. Reving goes ok without popping. I must say I never rode an XS before so no clue what to expect. I have read the carb manual but I must say this is first time carb adjusting for me.
Engine has a fresh rebuild top end with Heiden tuning 750, new valve seals and a new (never used) pamco iginition with mechanical advancer. compression is +- 165psi each side. Open exhaust and velocity stacks. BS34 with still stock jetting, 3 full turns open. (Heiden tuning recommends 145 main, 45 pilot and 3 turns open) The floats are new plastic ones and are set to 22mm. This is what the spark plugs look like after 10 miles.
