well....
I have 300psi of compression, and a wee bit of detonation, when under full throttle, so we are trying to rule out if the plug is getting too hot...and causing premature ignition or if its just detonation.
its a motorcycle, suzuki vx 800
I dont know enough to figure out all the sh*t thats happening, and I dont have anyone with experience with this engine (I dont think this has been done before) so I am trying to rule out x and y and z.
I had it dyno'd with Race gas, the mechanic said there wasnt any detonation (I am hoping hes right), with a 103 octane but now that its on pump gas, ....I am left trying to get it streetable, I dont care about power its now about getting it to survive.
