I built my bike, which in itself was a nightmare but after nearly 12 hours and lots of custom fabricating my experienced friend and I got the kit all ready. I have been lurking these forums for a while and will be posting in the High Performance Bicycle Engine Tips a lot since I am looking for plenty of power so a large guy like me (6ft 215lbs) can tackle hills with ease in southern California. I'm almost done breaking it in, just have about a 1/4 of a gallon of gas left to burn.
