The pick up coils can start misbehaving when hot. I've seen reference to this, possibly on this same forum. Needless to say, there's a YouTube clip of someone testing for this with an ohm meter and a heat gun. Might be worth researching as such a fault would cause the symptoms you describe. Good luck!Mmmm, done the pickups, no change. I'm gonna check the plug wires now. I'm getting a bit desperate.
I believe the engine is all stock. It came with the slip-ons and open airbox with K&N filter with acorns, so I did get the new filter last year. Like I said, it came with Dyno-jet needle/spring, etc. I'm at the sea level, too.Is the engine stock? If so I cant believe you would need that size main jet but then it depends where you live -I am in Florida on the east coast so basically dead sea level. I am running 135 main & it runs great
The plugs are NGK DR9EA, the one that I believe comes with CA Cycleworks coils. And yes, the little screw-on cap is off. Mind, I'm still running the old plugs that I cleaned up, still waiting for a new set.Interesting result from the needle change. What exactly are your spark plugs? Brand, Part Number and gap you are using. You took off the little screw on caps on the plugs, right?
I don't know, actually. When I found out that the coils weren't original, I looked up and saw that it was CA Cycleworks ExactFit coils, and DR9EAs are what come with it.Just asking a question--Is there any reason not to run the oem plugs on these bikes -owners manual says-Champion, RA6HC --
No, that is not true, NGK has bought other firms over the years but they are still the parent company. Renn - you are thinking of Denso (since WW2 actually )- different company.Is that so??? I didn't know that.
Float level - mine is set at 12.5mm actually (according to the caliper). It came that way, and it was fine, so I haven't change it. I was wondering about that, too.Also did you set your float levels? the spec I think is 14mm, but I had to set mine @ 15mm to work correctly but my issue was in the low speed circuit-my issue was dialing in the idle jets
