Just scored a pair of 17's 3 1/2" and 5 1/2" with disc's & sprocket ( already had a 17 x 4 1/2" ), and I have nutted out the rear end, but I want to keep the original type swing arm , dont want a 907 swingarm , but I want to lengthen the original and I figure that if I could get 2 swing arms I could cut and shut them to make one , with only one weld line , and I want to keep one original , sooo if any one in NZ has a spare ( or 2 ), no objection to sprocket bolt damage, Id love to hear from you .
The plan , roughly , is to fit the 900ss rear wheel ,sprocket carrier, axle & nuts ,spacers and floating SS caliper and bracket, and making up new excenters. The left with 5mm less on the inner side and the right recessed to accomadate the caliper bracket bushes , and both to suit the 17mm axle, and will look at keying the axle to the excenters ( Im gunna leave that to Harry the machinist ). Not sure wether I will end up machining rear sprocket carrier or fiddling with the front sprocket to get chain allignment right , depends too on wether I wind up using the 4 1/2" or 5 1/2" wheel. If anyone can see a reason why this might not work fercrissake say sommat!
I also have a choice of 300mm or 320mm disc's for the front ....... comments?
