I was hoping there might be more f5s than f4s in the gp would of been awesome

[F5 Dave]

Ahh now you're getting there.

That's what the clutch is for Haha

no ,its real bad , dyno day tommow , so hope to fix

[mr bucketracer]

runs up sweet then go's into this burbleing mess , thinking its the ignition breaking down now

[F5 Dave]

Sounds feasible. Put an extra set of reeds on top to negate them being too soft, then you are down to ignition or carburetion

running good mid to top now but rich down low to half mid

Throttle position or revs? `cause who cares about less than 9900?

when you go off the gas like going into a corner and back on it Boggs like he'll. Like it sucks in to much gas..not much ajustment in the kr carbs

Start by leaning the pilot then do what you can with the needle, Maybe get Bro to make you few new ones. (with a fatter taper)

But I suspect you slide cutaway is wrong. if you have a spare the same try enlargening it .5mm

You never did.

Sounds like jetting. Try messing with the needle jet first. Set it as far away from where it currently is and see what happens. My KERG100 was really sensitive to needle position and we got great results from simple needle height changes.

[F5 Dave]

So you're talking about throttle position. Get the pilot right first then the needle. I'd be surprised if the or one was unsuitable but it can happen. Check float not maladjusted and flooding, breathers clear. Heck take the pilot and emulsion tube right out and check not blocked up little holes, blow through front bell mouth orifices and check choke not leaking.

We used to have low rpm fueling problems with our GP125's that no amount of jet fiddling could cure. It turned out that the float needle jet pushed into the carb body and was sealed by a small "O" ring, these "O" rings had gone hard and were not sealing properly and allowing the carb fuel level in the bowl to go high at low rpm. No problem when you were running hard out.

Good call Rob, I bought a few of these and would replace them periodically.
