re-jet/exhaust recomendations please

[mortation]

Looks like I need to re-jet. I am getting carbon inside the end of my exhaust so I am way to rich but I still get popping. I do not know or see where there could be a vacuum leak any more and water does not cause a drop in idle (Unless I spray it in the intake DUH!)

I have some sort of aftermarket 4 - 2 exhaust w/o a crossover. Anyone have any jet kit suggestions and order links?

I DO want to get rid of my exhaust entirely for this one:

But it is going to be some time before I have the $$$$ for that :P


Or perhaps I should go for an OEM one like this:

Either way I am gonna drop the muffler and try using some resonators. I know it aint a harley but I like some rumble out of my bike

The best way to check your rich/lean situation is to do plug chops at various throttle settings (usually 1/8 (just off idle), 1/4 and full throttle. Your plug color is the best indicator of lean/rich.

But aside from all that, why go through all the trouble of re-setting your carbs, re-jetting (if that is required) if you're just going to get a different exhaust? You're back to square one.

I would get the exhaust you want on there first, and then go from there.

Welllllll its kinds running like poo cause I am fouling up my plugs something fierce and the occasional sputter is embarrassing lol. If I make it run better it will sputter a lot :P

All your plugs are fouling? That also could be weak spark, or perhaps a problem with your petcock, floats set incorrectly. Mixture screws set correctly? Maybe you've checked out all other options............but just trying to get more info. here. It could be something other than a jetting problem.

I had the symptoms you described exactly. I have VM carbs of course, but it turned out my mixture screws were way off.

My mixture screw:
1&4 - 2.5 turns out
2&3 - 3 turns out

Petcock is brand new OEM
Floats are exact, I think they were 22 or 23 mm. I set them to OEM specs.
Weak spark now thats possible. New Coils are on my list. The plugs are new. I could try a hotter plug. Last new set I pulled out were all fouled. I have not pulled the current new set yet though.

I want to get a colortune here as soon as money starts coming in again.

balancing

check you carb balance. 4 to 2 w/o x-over all the carb should be at same level,

secondly dont know what you have set the mixturn out different...get the colorune and skip the guess work
