I replaced mine #4 cylinder but no difference. Took it out and checked the plug for spark and I have spark.. what else can it be? Fuel pressure? I know it could be alot but what do you all think?

[@RBTheMechanic]

Could be injector or bad cylinder did u check compresson in cylinder

[@scottsuem3384]

@RBTheMechanic no it was broken down on the hwy.. it happened super fast tho..no oil at all, just a little wet spark plug.. checked for spark is all I could do and it had spark. I was thinking fuel pressure?

[@scottsuem3384]

@@RBTheMechanic other than the fuel pressure. What about the fuel injector? What do you think?

[@RBTheMechanic]

@ yes could be bad injector fuel I wouldn’t say pressure then all cylinder would be effected check compressor and then injector u can also disable the coil and then u will see we’re plug to see if the I next is spraying

Hey Ralph Bob The Mechanic!, can a evap-canister make the engine misfire?, or how can you tell the evap-canister is going out? As in the valve is stuck open or closed?

[@RBTheMechanic]

Well u will have codes for evap I had one car had bad purge valve car misfired and stalled on road due to too much by pass air entering the chamber

[@geoepi321975]

,hi RB, does low compression cause rich combustion on a single cylinder bike?

[@RBTheMechanic]

Yes I believe so

[@johnhorgan5313]

No it certainly does not. There will be low compression and some of the fuel will escape where the compression is lost. Eg. past the valves.
