I need help guys. The bastard Suzonda won't fire up.....despite our best efforts.
Freshly rebuilt with new crankseal/bearing etc, all professionally installed and the engine built up by a very experienced bike tech.
Slotted in to the frame and it fired up and ran, lovely.
It then sat for 6 months....when I tried to fire it up again last month it wouldn't??
Found the old fuel had gone stale and a green residue had coated the entire fuel supply, petcock gauze, inline filter and carb internals, float bowls had a green waxy residue.
Cleaned out everything, left out the petcock gauze and fresh fuel/oil 25:1 mix (until the oil pump would bleed) but still wouldn't fire.
It's trying to fire but no amount of testing, new coil & plugs but still it won't run.
We suspect the centre crank seal as there is some blow back through the carbs....surely that's not right?
Getting good compression (no readings, but a finger test) having spun it up on the starter it's trying to fire and there is a wisp of exhaust, but no response on the throttle.
We've splashed fuel through the plug holes and syringed some through the carb intakes....nothing.
Spark is good n strong.
The generator/flywheel appears to be fitted correctly, on a keyway, there is oil in the gen case but that's normal, right?
The manual I have states ignition timing at 24* BTDC.....how is this measured or adjusted?
We suspect the brand new centre crank seal has failed as the blow back through the carbs is not normal, is it???
Is there something we're missing??
Any input appreciated, thank you.
