I have a set of 88-90 forks on a FJ1200. I have new 1.0kg fork springs from Race Tech. The springs I have removed from the forks (stock, progressive, who knows) measure 375mm with no spacer. The parts fische I have seen shows preload spacers. My RT springs measure 315 mm. When I called to ask what length to cut spacer (springs come with a piece of tubing & washers that you cut for spacer) I was told to measure stock spring & spacer and to make the new spring/spacer assy the same length as the stock pieces. IS there a spacer in these forks stock??? or do I just cut a 65mm spacer to make new spring/spacer the same length as stock spring.
