Hey guys so i am going to get a volt meter on it this weekend but i want to know your thoughts for now, on my 1992 vxr 650 i thought it was running smooth (since it was running 30mph at least few weekends back) but i guess not, now here is my problem. I had it running on a hose in the yard just now, i decided just to pop off one plug wire and see wat it did (2 cylider engine 2 stroke) so i poped of the forward most wire. (engine died instantly). Put the wire back on fired it right back up no problem. Took of the rear plug wire i head a clicking noise as the boot was coming off like electricity clicking, but engine had no change. So i took both plugs out and cleaned em up, one on the rear was the most dirty. Then i swapped the plugs so the front plug was on the rear and started jet ski up (easy start). Did the same thing in same order pulled front plug wire off engine died, pulled rear plug wire off no change but still hear that clicking noise when boot gets near plug.....


Sorry about the bad gramer and punctuation.

Ok so turns out its not electrical, its fuel and i tested the therory today. I pored gas into the cylinder thats not firing and it cranked for a few seconds on that, the other cylinder is getting gas. what could this be...

Maybe the reed valves need cleaned or replaced?

Good luck!

To ensure that it is possitively not spark related is to pull both spark plugs, install the wire boot on each, hold the boot and touch the threaded part of each plug to the cyclinder head and you shouls see the plug fire. If a read valve is bad your engine will have low power. A reed valve is kind of like a check valve, they prevent combustion pressure from entering back into the intake system.
Did you loose power all of a sudden? has the machine been sitting for a long time, need more info.
