Nice Bike!
I went to 21mm Delortho carb with the stock throddle and calble as recomended by MK for the pro race Pipe and It solved all my problems. Now I use a 98 jet all day long and rides like a champ.
That's a Derbi GPR50 neoroarke. My bro is pretty handy with a can of spray paint. You should've seen his Repsol, R6 Limited Gobert Edition, Haga R7 Superbike Replicas. Man bro, you've done a bit huh.
reyefumi is my older brother. I meant he created a few replicas with spray paint cans since we started racing. I just dont' crash as much as he does :laughing
