Want to build the donk from bottom up, any sugestions. Bike has 42000 on it and i want more grunt. FXST.
Mate about all you can do is spot weld the pin to flywheel. but you need to find someone very experienced.
If you leave motor relitavely stock should be fine without welding the pin. but if you change cams raise comp, make sure you match the cam to the comp, so cranking pressure does not go too high, but then again you need around 180psi cranking to make good power n torque. what are you after?
cheers
Thanks for the input, much regarded. Rode the bike home and stopped for smoke after 260 km or so and all the winni blues backy was at the bottom of my packet, all the smokes were empty. Ran fairly hard though on open roads but want to start from the bottom up. Being a b - balanced motor with counter balancers in it, if i change the weight of the pistons i will change the balance counter effect. So i figure i need some help. I would love to go big....why not, i only use the bike for forty or so km runs now, but would love to shread some rubber on the way. Want to do it once and well, but lack the knoweledge.... just thought that a well thought out , understandable plan is in order. Again thank you for your input and i shall keep posting all the details so that it can be documented for all to prosper from the endevour.
