My bike was shutting down whenever it warmed up, say two to 5 minutes into the ride. It would stay on with the throttle open but shout down when I let go and never restart. Then the following day it fired up normally, that is when it got cold. So we cleaned out the fuel lines and thought all was well. It stayed on for more than 15 minutes this time. Well the following happened..

Ok it started all over again. Especially if I ride the bike hard that is 5 to 10 minutes
at high throttle. It would start to pop on the down shift and then eventually shutdown and not restart
We took the carb apart and it was clean. We checked plug sparks, no problems.
Tried to start and when we took plugs out again they were dry. My mechanic said they should be wet. We started tracing fuel lines and eventually noticed the equalizing line dry. We disconnected the bottom of the carb and nothing came out. We tapped the housing and then fuel came out. The float was stuck. Then it overflowed, so it got stuck
in the fill position. We determined that when the carb heated up the float was sticking and thus starving the engine with no fuel. That was why when it was cold it worked ok. Anyone ever have this issue???? I am using a Big AIR PSI. What is the fix? Thanks!

What I would do would be to call call Bob at XXX Carbs. real nice guy and is on top of it when it comes to carbs. one of the nicest guys you will ever talk to. If he cant help you it was still worth the chat.

Sounds strange,keep us informed.Is it possible that there is some shit in the needle valve assembly causing that to stick? could be way off base but,I don't claim to know alot anyway.

unless its just shit gummed up in the bowl holding up the float pivot or needle valve id say youd have to contact Bruce at PSI for support.

or you can contact R&R cycles. they built the gen4's

the only problems i've had is cables breaking in the grip housing. can change it in minutes now.

Can you just order a rebuilding kit and change the needle and seat? Then with the instructions you can reset the float height. Then you will know all the parts associated with starting and stopping fuel flow to your carb are new and adjusted correctly. Just a thought!

I had a Yamaha a few years ago. I got it cheap because the PO had brought it to 3 different shops to fix the problem. They didn't ever fix it. It was doing about the same thing as your bike. After pulling the carbs apart a couple times, I noticed the seat for the needle valve had been deformed from being overtightened.They were sticking. I put in new needlevalves and it ran like a million bucks.
