Would love to see an updated video of you driving through all the gears hmmm, you may be onto something with the coil wires, however I didnt cut the wires back as the coil is only about 6 months old, and I swapped a coil from my buddies bike as well making no difference. I had another CDI, albeit an aftermarket one, that I had swapped out way back in my orig diag, and Kevin had his own CDI on his bike that my motor was swapped in, still the same. I was trying to think of what was different on Kevins chassis compared to mine, which would be the coil, wiring harness, CDI, and fuel lines/fuel tank. Already tried shortening/straightening the fuel lines to no avail. I havent taken another video of it as it runs pretty much the same as it did in that first video, it will barely move in the higher gears unless i get good enough momentum in the lower ones.

gusto Posted February 11, 2018 Report Share Posted February 11, 2018 OEM coil on your bike or aftermarket? tru running a ground from your engine (stud) to your frame just for the hell of it cant see Kevin lying if there was a problem Quote Link to comment Share on other sites More sharing options...
hoppedupandcutdown Posted February 11, 2018 Report Share Posted February 11, 2018 Wiring harness, I've seen one ohm test good, but in this case had the wires from the pickup coil actually down to few strands. It ran fine but would fall on it's face and stutter when the RPM climbed. Quote Link to comment Share on other sites More sharing options...

However ive already swapped a known good coil from my buddies bike, to no avail. Also I have ran a ground strap from engine to frame as well, just for added assurance 1 minute ago, hoppedupandcutdown said: Wiring harness, I've seen one ohm test good, but in this case had the wires from the pickup coil actually down to few strands.

I removed the wiring harness, went through and removed all unnecessary TORS wiring and what not, ohmed out and visually inspected all terminals and crimps of each individual wire, and re-wrapped it, all was good, made no difference Quote Link to comment Share on other sites More sharing options...
hoppedupandcutdown Posted February 11, 2018 Report Share Posted February 11, 2018 This had wires (all but a few, 2 or 3) broken inside the insulation. Undetectable until they completely broke. Although I've ran across it before on GM HEI distributor harnesses and if you feel every mm you can feel the soft spot. Quote Link to comment Share on other sites More sharing options...

Canadianshee Posted February 12, 2018 Report Share Posted February 12, 2018 I do apologize if you checked already, but did to clean off a frame where the coil mounts and your frame ground wire ect. This does seem odd that you are having this issue. We used same builder with same mods other then the head.

dano3 Posted February 12, 2018 Report Share Posted February 12, 2018 I know that you have been through the electrical side of the bike per the first post but are you using the stock kill switch? My bike had an intermittent bog issue when hot and i could induce it/ resolve it by playing with the kill switch connector near the radiator. Ended up fixing it by putting some dielectric grease on the pins and wrapping a ziptie around the connector to compress it. it would rev out when in neutral but any load on the bike and moderate throttle it would fall on its face due to a weak spark. Something quick/ easy to check before pulling it apart. Quote Link to comment Share on other sites More sharing options...

Ill have to check into that, good call Quote Link to comment Share on other sites More sharing options...
gusto Posted February 12, 2018 Report Share Posted February 12, 2018 since you have access to your buddies bike try using his harness Quote Link to comment Share on other sites More sharing options...

Ayesully810 Posted February 12, 2018 Report Share Posted February 12, 2018 if it ends up being electrical, thats one reason i gut ALL the electrical components and run a cut wire harness. makes electrical diag. easier and cleans the bike up.
