sounds like your throttle slide cut away my have gotten out if size for the mods you have done

Maybe need a larger cutaway to let more air in?

[cxman]

i need a review of what size carb and what you have in the carb slide jet needle needle  pilot main and air correct

motor and mods i have lost my place sorry

so i cant tell if you need richer (smaller cutaway) or leaner

from the size of the pilots i am wondering if you need smaller or you have to big a jet needle and no low end air velocity

so you have to run big pilot

fill me in then i will know

[johnu]

Cx man' here is the spec on my carbs:
vm34's
Main Jet - 260
Pilot Jet - 25
Needle Jet - Q2
Needle - 6FJ6
Needle clip position - Start in the middle
Slide Cutaway - 2.5
25:1 premix using castrol 747 and Sunnoco 110 unleaded race gas.

Ok so I fired it up today and she does run better on the 25 pilots.  Still not great but I think I will try lowering the needles a little bit to see if that helps.  It still seems woolly down low.  While it was running I whipped off the uni filters to see if that what make a difference and it seemed to be marginally better.  What I noticed is that when you give it a big handful of throttle it seems to initially blast a good amount of vaporized fuel out the back of the carbs.

I will put the filters back on and take it out for a few miles tomorrow to see if it gets any better as I'm riding it.  Got to go and pick up some more unleaded race fuel first

John, what does your spark plug(s) look like?  Check them tomorrow on your ride.

first verify your initial timing and timing advance

and i found some old notes (old)

last race bike i messed with had this

Pilot - 35
Cutaway - 2.5
Main Jet - 260
Needle Jet - 159Q0
Needle - 6DP17 in second groove from top

no air correct jet

Well I rode the 500 today and it was not good.  First off it had nothing down low then after about 1/4 mile it started running on one cylinder.  Managed to ease it back home and took the carbs off.  Left side carb had no gas in it and the left side plug was clean and not burnt at all.  Turned the gas tap on and a modest trickle coming from the right side fuel line and only the slightest drible on the left.  Disconnected the fuel line at the fuel tap and fuel flow there but not great.  Going to remove the tank and check the fuel tap for blockage.  I have my single fuel line coming out of the tap to an inline filter then another piece of single line to a Y piece then to the carbs.  Not sure why more gas flows to the right side than the left
Once I get the gas flowing correctly to the carbs I'm going to reinstall the 35 pilots  As I see it there is no reason why the bike shouldn't run half decent with them in there.

How large, "inside" diameter is the fuel line from the petcock to the Y?
