Hi guys
I have a pulse adrenaline with a 150cc kit, stainless steel exhaust, custom air filter, with the vm22 mikuni carb.
Now I have a #100 main jet with a #20 pilot jet. The bike runs fine, however when I hit the 7k the bike starts to fail. If I push hard the acelerator the bike goes fine and start to gain revs. it seems that it only fails in a specific acelerator position...
What do you think about my Spark plug?is the mix ok?
