Need help Quad 90 upgrades

[outbackquad]

My 6yo daughter wants her 90 Pred to go faster. She races MX and enduro against two wheelers!! as there aren't that many Quad racers here, and she found that it doesn't go quick enough. I checked the CDI for the jumper. I have been given free rain by wife to "IMPROVE" the performance. Now..... its all mechanical changes. I wanted to upsize the front sprocket and down size the rear has anyone got a good combo for front and rear sprockets at the moment Im running a 19/35 ratio? Also looking at modding the airfilter box. Its hard to get any upgrade parts or info as quads arent as popular here in Australia.
Please any info would be appreciated..

You can also try Billy Holt at WRH Racing. Their site is:

Before purchasing single performance parts (from any performance dealer), do properly describe what riding conditions and "performance output gains" you are looking for. Depending upon your unique riding conditions, different bundled parts are used together. For example, WRH Racing offers different WARP packages. Each single part in the package is optiminal aligned for the other parts in the same bundle. For details, surf: http://www.wrhracing.net/engine_kits

Also, do consider upgrading the Pred-90's suspension when upgrading its stock engine. No use having "a rocket" if your young rider can't handle it during the higher bumps and sharper corners.

Hope this helps....
