My Tomos starts first kick and rides and idles well.
I can ride it all day.
I have a problem at WOT where the bike jumps / lurches / surges for a few seconds then stops. Sometimes it will do it until I let off of the throttle, sometimes I go WOT for 10 minutes and nothing happens. It never cause it to shut off, it just acts like it needs fuel.
It doesn't feel to me the same way lean and rich bogs have felt on past bikes that I have built.
The way the bike jumps is the same way a bike kind of starts jumping when you are running out of gas and need to put the petcock on reserve.
I can see gas in my line (its a clear fuel line).
It has a fuel filter, I see fuel in it
I'm not sure if the gas cap is venting properly or not.
Jetting: I've went from 78 to almost 88 jet size and have the problem at all ranges
