Hi there!
Just installed a boost bottle on my 80 cc Zoombikes Kit. I have noticed a significant upper end power band improvement, with the lower end lagging a little more than usual.
There is one problem I have however.
When the clutch is Engaged ( Bike Running under Motor Power) the bike runs fine and sounds just like its supposed too.
When the clutch is Disengaged ( No Motor Power To Bike) the bike suddenly revs really high, like super high, almost full throttle sounding. If you wait a little bit while standing still ( But not coasting) it will eventually come down ( approx 20-30 seconds later)
Any ideas on what could be causing this? My first thought was a sticky throttle slide but that all seems A.Ok, and I have already played with the idle setting on the STOCK carb, getting it as low as I can w/o stalling. Bike seemed normal before the boost bottle install, it works great and I don't want to get rid of it if I don't have too !
Thanks in advance,
Steven Gill
