Hi Skunk. 21 H2150 Built December 1957 as a 1958 model and shipped to Triumph Corporation, Baltimore, MD. Yes, most of the 1966 parts will fit. Can I also suggest you fit a primary chain tensioner from a BSA C15 as your bike does not have one. If you fit a new chain, don't bother with the above.
Do you also have the distributor? If so. check the adavance / retard mechanism, fit new points and condenser.
Great little motors and almost unbreakable............. you do have to wiat for the power though!!!
Yes I knew it was a 500. I thought that All Triumphs went to "unit" in 63. So that is why I did'nt think it could be a 58. The 66 in the photo (on the right) was locked up when I got it (see gears in 3rd pic)and thats why I picked up the other lower end. Is there any required reading about owning a Older Triumph? 500's or otherwise... so thats not a wrench....anymore? I've been useing it as one on the big slotted screw caps....
I guess maybe that I did'nt "know" it was a 500? A 350?? I will let you guys hash this out....Woody, I know that the #s start with H47xxx if you need the rest I'l have to go to the shop...Thanks guys still waiting for more......
Both TBS and GPZ are right....... it's a Twentyone, 350cc BUT it has been fitted with conrods from a 500. The Twentyone had steel conrods with a smaller little end bush.
Skunk, the plate/spanner/tool in the picture next to the timing gears does not fit any Triumph that I know?

When Everybodys Right! Thank you all. The "tool" came to me years ago in a box of Triumph parts, I thought it looked like one tool in a emergency kit....yes panda I saw those hiding in there...Those timing gears are out of the '66. It looks like a fresh rebuild, except for them gears. and the slop behind them.
