Well 525XC enthusiasts I have made a tough decision... I've thought about this for some time now and have decided that I'm going to leave the 540 and go with a 600cc kit. I had an offer from Travis at Thumper Racing to do this build that will include anything he can think of for mods on the engine to make it run with the best of them out there. I told him I didn't want to lose the dunability of this machine or the reliability, so it will take some creative thinking to come up with the best of both worlds. As for the dunability I think it will mainly be with the swing arm length. The reliability will be up to Travis and his engine building ability, which is second to none out there. So please let your imagination flow and give me your thoughts. I will answere any questions I can as some of the parts and pieces are a little bit fuzzy to me yet. This build should be done by the middle of Jan so as it comes along I will keep those interested posted.
