So my friend has a X1 and he ordered the ''performance package''.
It was supposed to come with:
-boost port piston
-rocket key
-exhaust
-race carb and cable.
So it was missing the rocket key so we machined one out of a wider key but once we assembled the bike with the boost port piston, it was actually more sluggish. Thinking about it, the boost port on the side of the piston would indeed help when you have reed valves but the X1 does not use them so I wonder if it allows the air mixture to be pushed back towards the carb.
So my question is:
Has anyone else used these ''performance kits'' on a X1? We're trying to setup his bike so we can go and have some fun so I have some interest in seeing his bike run good!
P.S. we have put the original piston back in and it seems to be better... are we missing something?
