I've searched high and low, still no definitive answers, so heres my story.
About 6 months ago I bought an fl350r.
Guy claimed it was freshly rebuilt and properly broken in. Everything replaced, leak down tested
Compression at or near 150 psi. New seals, ect, ect, ect a complete motor (( Internal Combustion Engine ? )) rebuild. Only thing was the starter wouldn't engage. (It would pull start first pull everytime and run like a raped ape) but the starter would spin, just not engage. Was told it needed a oneway bearing. So I bought a brand new starter. After killing a few knuckles, I replaced the starter I got it all back together. Long story short, wasn't the starter but a bad cell in the battery. Thanks Methodical for that bit of info. After all that work and a new battery, it ran like a beast. The GPS, after 3 passes around my neighborhood, stated I was averaging close to 65mph. But on the 4th pass she starts to bogg down at half throttle and continues to go slower and slower until she dies, just as I pull into my driveway. I searched and found a wire from the stator, fried and I mean crispy, crunchy fried. A facebook friend has a used stator he sent me. A little dusty but looked almost brand new. I install it and bam, back to screaming. So I'm out ripping it up, burnt a full tank of fresh gas, mixed at 32-1. And again she starts to bogg down as she did before. Thinking the stator wasn't the problem I started changing all things electrical. Replaced everything with new parts, the solinoid, the coil (twice), the CDI (Capacitor Discharge Ignition) (from a running buggy), grounded the DNR switch, rechecked the leakdown (holds pressure over 30 mins), rechecked compression(the same,150psi), cleaned the carb, replaced the fuel lines and fuel filter. Replaced the pulse hose and fuel pump.Tried running without silencer (it was clean) tried running without breather box top with a new air filter. No, there was no oil on or in the starter or stator. The motor (( Internal Combustion Engine ? )) was completely rebuilt and spotless. I've researched for months, asked everyone who would listen and answer. Ive tried everything everyone had recommended. My last attempt is to install another ground wire from the motor (( Internal Combustion Engine ? )) to the frame using a starter ground wire off of a riding lawnmower. I do have another new stator but wanted to rule out every possible problem so I don't burn though another very expensive stator.
Anyone have any ideas where I should start looking? The buggy starts, idles (when warm) and runs, just not over half throttle. Motorcycle shop claims it's running rich and that a carb tune is the answer. My gut tells me its electrical as it ran like a beast each time I changed the stator.
Any ideas or where I should look?
