I received board member Ralf's lab seals recently offered in the for sale section. They are really nice . I can rebuild your H1, H2,S2 crank . I will personally work with you and your budget. I have rebuilt multiple crankshafts in engines that are currently running and racing across the globe.
I pride myself on taking the extra steps to get the crank back in a condition as if it was going in my own bike. I can assist in giving advise to get it back together if needed.
As far as pricing it really comes down to the quality of parts that you choose to use. Sometimes the OEM rods are reusable, if they haven't seen water, corrosion or some trauma. Otherwise they need replacing. You can choose to supply your own parts, or I stock parts myself.You can use top quality bearings and seals, or no name bearings and seals, depending on what your going to use the crank for and your budget?
Most folks want to run their bikes and have them run well, they choose to use top quality parts. Just like this H2 crank I finished for the board member here John. Im telling you this came out straight! I thought my dial was broken as it hardly moves. I told him how nice it was use top quality new parts because of the results. In street use the crank may outlast the rider? So rubber seals, lab seals ,new parts,used parts, it all up to what your comfortable with and your budget.
I can take your crank apart and give you my recomendations. Im a Master Technician with 36 Years of experience in the Automotive industry as well as involved with Kawasaki triples since before I had my drivers license.One thing for certain if you suspect that your crank is worn , bearings are noisy, with a chance to spin, or rods are questionable or seals leaking then it probable is.
