We have tried all the mods and there is only one way to sort the problem.

This little motor being a non reed engine it makes it hart to change to inlet port and as we all no we must get the air in to make them go,, so what you need to do change the port timing by lifting the cylinder and lower the head.

QUADMAD RACING in Australia has done alot of research and have figured it out and can make you little quad climb up the hills..........they also have a good cheap shocky set up for the front that works all so. QUADMAD RACING will be seliing these kits as of December........and it's cheaper than buying a pipe.
