Strange symptoms...

[Dragmaxster]

Ok... It was determined the PO had the floats leaned way out to compensate for a set of huge mains. After Danny set my floats to factory height, the big mains were causing the bike to load up after prolonged idle. The bike still had a high speed bumble which was determined to be lack of carb vent lines resulting in incorrect pressures or something when catching gusts at speed. My final tune is as follows: 147.5 mains, all other jets stock, 1 shim under clip on needles, idle mixture screw at 2.5 on front left (#2) carb with the rest at 3.5, k&n filter in stock airbox WITH "Y" in place, full Holeshot 4-2 exhaust. Bike runs absurdly well.

Glad to here it's going well.
When you say lack of carb vent lines are you referring to the 4 that go up to the airbox?
I have 4 for sale if you need them.

I just slapped on a few lengths of fuel line. Works like a charm!

Glad that it was a simple fix. Usually the carb problems that are posted on this forum are issues caused by the PO and then they sell the bike.

Be careful that they do not get crimped because it will not run right.

That would be correct.

Something doesn't seem right if you got one idle mixture screw at 2.5 & the others at 3.5. :ummm:

But the screws from the factory aren't all the same turns out.

As I understand it, it's entirely possible for one carb to be less/more sensitive than others. Danny?

Very true.
