Bike is a 06 fxdi that was converted to carb.

Dont know now much about carbs.

Can an anyone tell me what is going on. Sluggish throttle response. Smoke. Sounds like a go cart!

Whats the fix? Rejet it?

What make and model is the carb? Where is the smoke coming from, when does it happen and what color is it?
How do the plugs look?

 

Is it running on both cylinders? How old is the gas in the tank? Don't expect it to run right with no air cleaner.

 

Mikuni 45. Going to pull plugs this afternoon

 

Converted to carb? may that be an issue? electronics issue, ignition module, timing etc..if all is good with the conversion, be prepared to go with full tuneup. Plugs, carb rebuild/rejet etc. Also, someone in another thread mentioned compression, I learned way back in automotive school you cant tune an engine with broken internals, Do a compression check, once you figure the engine is tuneable, go for it on the tuneup.

 

EFI to carb conversion needs a stand alone ignition to work. ECU is basically useless, it only runs the speedometer. Before you start rippin something apart, check for a vacuum leak at the intake manifold seals. I have an 07 Dyna converted to a CV-40, so I'm gonna give you the best help I can.

 

The two holes in the heads are vent holes for the heads/rocker boxes don't plug those. To me sounds like it's running on one cylinder at idle. The mist coming out of the carb is gas and is some what norm. I would search the net on basic set up for Mikuni carbs as a start point. Don't give up, search the forums on DIY for Mikuni carb. tuning. If it was a Keihn CV40 we would be all over it.

 

as said, are both pipes getting hot?

 

Wise post. We put a tester on everything that comes in the shop. I bring one when traveling to check out used bikes. Many omit checking compression out of wishful thinking or assuming no blue smoke means good compression.

Determine what aftermarket ignition you have (assuming one was installed, if not then that needs to happen).

Very good idea. When I work on a kitted bike that runs poorly I recheck the whole kit installation process because install error is so common. Every new-to-me personal bike gets new seals when I clean and inspect the carb. Find which carb you have. Photos can help us help you. Once you know the carb kit you're dealing with you can find correct jet/needle settings from the manufacturer or owners.
