I have a T100 motor and a 500cc frame. Year of frame unknown. Finding parts for a 500cc model are hard to find. My question (and it's probably a dumb one) is can I fit T140 parts on the frame. Forks, fenders, tank wheels etc. without a major hassle? For a complete build.
Fitting T140 cycle parts isn't as hard as some say, but there are a few snags. The rear fender will need to be cut for the oil tank. No biggie, I've done it a few times. The rear fender brace may actually fit straight on.
The forks may pose a problem, as the T140 triple tree stem is slimmer and shorter. The best plan is to buy one from a Trident, which has the correct dimensions. I have actually modified a T120 OIF tree to fit a "dry" frame by extending the stem and crimping on a ring for the bottom bearing, which has a bigger ID (and OD) on the "dry" frames. Not hard to do if you have access to the tools or a machine shop. You need to make a spacer for the upper bearing as well.
