hi all, I have several roadsters and 1 csr, and would appreciate any information on where I can buy a new primary and balancer chain from,otherwise I will be forced to replace all the pins myself, also gearing these bikes up makes a decent bike of them, all kwakas seem to be geared for sprint times, I replaced the standard 38 tooth rear sprocket with a 30 tooth and what a difference,she now does 3000 revs in top gear at 100kph right on max torque, right where its needed and performs better by making use of all that lovely torque,and keeps up with the fours!
