fuel problem

[Scott75]

I have a 98 banshee,, I have shaved head, full procircuit exhaust system, mild port and polish, bored 60 over, 4mm long rod stroker crank, boysen power reeds. All of these items are brand new.

I have a pair of used 28mm keihin pwk dslide carbs. The right bank was smoking more so I swaped sides with the carbs. And the right bank still smokes more than the left.

The left plug is a light chocolate brown, and dry. The right bank that smokes alot is black and wet.

I have run out of any ideas to try. Any help is greatly appreciated........

sounds like you have a leaking crank seal or case,but the first thing to do is a leak down test,then a compression test.I would start there first,hope this helps

Thanks,,, but I forgot to add that I had yamaha do the leak test and it passed with flying colors. I did the compression test and it was within 2 pounds of each other,,

have you tried switching plug wires to see if you are getting the same amount of fire through each plug wire and you could also check your reed cages to see if they are cracked or damage. sorry I just seen in the post that the reeds are new.

Did you try a new set of plugs. I had a plug one time that had a hairline crack that would fire but very weak. Or maybe a intake boot leaking air.

Put new plug caps on and change your packing in your silencers just to start fresh
