Question Overheat or Lean on pilot jet

Should show in signature what my parts are. If not will list them after post. Or please ask.
2000 883 XL upgraded to 1200, with stock 883 gearing. Daytona Twin Tec Ignition running stock ignition map and Mikuni 42mm SE carb and heavy breather and branch ported heads, and bob woods .590 lift cams. Vance and Hines straight shots with baffles.

Also have VOES changed to higher vacuum I believe from previous threads I have read.

In Sturgis last year, I noticed after riding slow thru iron mountain road and needles highway, that after a bit sounded like engine was getting too hot ( and even could feel the heat) and sounding different. I could rev it up with clutch in and give more fuel then would go away, or when riding faster would go away.

I just re-built the whole top end and replaced the piston rings with new ones... de-glazed and re-honed the cylinders with a good cross hatch. Lubed up pistons, put cylinder's back over rings etc.

Rode 3 hours to event in Findlay Ohio from Indiana to break rings in, (Kept RPMs under 4 grand) stayed for a while, then on way back, when coming to lights or stop sign I would notice it sounding weird like maybe over heating (same as was from riding in Sturgis black hills). I was running SAE 50.

The weird thing is, that it ran strong and loved to pass cars at 90MPH on way home, after engine re-build and ride back home from ohio to indiana.

Until get a base line Dyno run, to help give the tuner info, was curious what the forum could brain storm.

Runs strong with more throttle and doesn't sound weird or anything and engine loves it. But when car in front is driving 55, after doing 90 till I catch up with it till pass it, engine will make a weird sound, and like losing power or something.

But once I get back on the throttle and pass the car and keep going fast, or maybe the sweet spot, it runs strong and engine is great.

I'm either thinking maybe add possible oil cooler, or pilot jet is too small, and or needle needs changed.

I'm in Indiana, so when go to Sturgis and black hills, it already runs richer with the higher altitude. So not too sure about the running lean, since same symptoms in Indiana with lower altitude to run leaner than black hills since altitude difference. Unless is still off on pilot jet or needle size or needle clip height. I need to get my notes from my carb manual back out also.

I have an upgraded newer model year higher flowing oil pump in it also prior to sturgis last year.

Any brain storming ideas anyone?

Good thing is, NO oil leakage after put back together. I used scotch brite pads and spray on WD40 to clean and scrub all gasket surfaces, combustion chamber, tops of pistons etc. And used the Holymar Blue M formula on metal gasket surfaces, mated them, then removed them. Let the acetone I think that is what is in there, evaporate after 20 minutes, then the stuff never hardens. Put gaskets on, and re-assembled, and torqued all bolts to factory specs. Not a drop of oil on garage floor after the Indiana ohio trip and back.

I'm also using S&S rocker boxes.

Just not sure if need oil cooler, but then again, if running slow, not enough air would be getting to oil cooler either?

Thanks for any advice.

Again running fast at 90MPH engine runs strong and doesn't act weird or seem like over heating. But when slow down (less throttle) , stop light, stop sign, will run weird, but go back to running strong after getting back on it going fast.













Ride it like you stole it.

Were there any noises? Maybe you have bad lifters?

Just weird engine noise when came to stop at stop light or stop sign after riding fast, like an over heat loss of power noise. Lifters are good. Or would "always have a weird sound" I would imagine?

Like mentioned... when putting on a lot of throttle, engine is strong and runs great at 90MPH and no weird sounds. Don't think lifters would have any thing to do with heat issues. But thanks for the feedback. Much appreciated.

Looks like, at least the front cylinder, is overheating. You shouldn't have blueing that far down the pipe. Or did that happen during tuning? Are you sure there is not a leak at that seam as the bike warms up?

Not necessarily that would always have strange noise. Mine had only when engine was hot or if I'm more specific, they start to tick when I lowered rpm after some reving it higher.

That happened years ago when static timing a new ignition module. I was stupid and used the timing light toooo long in the garage.
