Ok, so i decided to fiddle with my CRF a little more as per the Thumpertalk posts.

The exhaust muffler was already cut when i got the bike, and the spark arrestor removed. Issue is that this makes the bike run lean. So i changed the jets last week, and cut the entire top off the airbox. The bike now seriously hops, was at Wild West on Saturday, and the front starts lifting nicely with a bit of throttle in most gears.

This morning i did the accelerator pump mod (not needed from 08 models up). Took me about 2 hours, so not a big mission. Will report back on Thursday about the improvement.
