I have a T140D that I just finished reassembling with a fully rebuilt engine. Work on the engine was done by a local motorcycle that does a lot of vintage Triumph work. Just got it running and it is not shifting gears right. I cannot get it to shift into a neutral position, I can find a neutral spot in the area where the neutral light comes on but there is no sign of a detent dropping in and it's a very touchy position with wanting to drop into gear and not stay in neutral. Can the trans cam be put in backwards? when I shifted it into what should have been 1st gear and rode it it seemed to be in 3rd gear, certainly wasn't engaging 1st gear. I'm believing the cam plate is flipped over. Ideas? Comments?
