I just ran across a cheap 76 TS400 and want to make a fun motocrosser out of it. I also just picked up a 74 TM400 top end I want to put on the TS. I heard the frame downtube may interfer with the exhaust so I may have to modify the downtube, but does anyone else have any advice on what other modifications they may do? Thanks in advance. Keith |

I replaced crankest and bottom bracket with a used Shimano 105 39/53 tooth. The gear ratios with the stock chain ring are too high. The 39 tooth front ring makes for a much more useful bike. and Replaced folding alloy pedals with Shimano SPD pedals. I prefer SPD pedals and cleats and the non-folding pedal is not an issue. |
