jas Posted September 29, 2015 Report Share Posted September 29, 2015 TY350, sat open out in the weather for a bit, crank is stuck transmission is free, I have the rest of the parts minus the wrist pin. Bore and piston are perfect. If it's worth rebuilding I'll send it to B&J Racing, just looking for opinions.... I know, it's a crime but I'm not the one who did this!

lineaway Posted September 29, 2015 Report Share Posted September 29, 2015 Oh, it`s worth it. The cylinder and piston were the parts unavailable. So a little strange. 1 Quote Link to comment Share on other sites More sharing options...
jas Posted September 29, 2015 Author Report Share Posted September 29, 2015 Oh, it`s worth it. The cylinder and piston were the parts unavailable. So a little strange. the cylinder and piston got pulled years ago. They were boxed and set on a shelf. Quote Link to comment Share on other sites More sharing options...

Spoke with Bob @ B&J Racing this morning, it's headed his way to become a seriously built engine.... Quote Link to comment Share on other sites More sharing options...
monty_jon Posted September 29, 2015 Report Share Posted September 29, 2015 What’s the going rate for a full engine rebuild? Quote Link to comment Share on other sites More sharing options...
jas Posted September 30, 2015 Author Report Share Posted September 30, 2015 Not sure, upon further inspection I decided to just send him the head, reed cage, and cylinder for a port job, reed job, head job and piston kit. Quote Link to comment Share on other sites More sharing options...
tony27 Posted September 30, 2015 Report Share Posted September 30, 2015 Are you going to be able to source a rod kit, looking at the photo the crank is likely to need rebuilding as that little end bearing looks like it will have pitting the surface it runs in & the lower bearing will be the same Quote Link to comment Share on other sites More sharing options...
lineaway Posted October 1, 2015 Report Share Posted October 1, 2015 Tony 27 is correct. No sense doing the top end and not the bottom end. There is a crank on e bay, but you still will need mains and seals. Quote Link to comment Share on other sites More sharing options...
jas Posted October 1, 2015 Author Report Share Posted October 1, 2015 I will rebuild the lower end myself, I have found everything I need, including that crank on eBay ;-) I figured I'd do the stuff I am fully capable of and let Bob do the rest. 1 Quote Link to comment Share on other sites More sharing options...
lineaway Posted October 1, 2015 Report Share Posted October 1, 2015 Has Bob talked about lightening the flywheel? Makes a world of difference, depending on how hard you plan on riding it. Quote Link to comment Share on other sites More sharing options...
jas Posted October 1, 2015 Author Report Share Posted October 1, 2015 Yes, that will be done to this engine too. This engine is off my "parts bike" but the more I think about it, the more I am leaning toward making the "parts bike" a complete bike.... Not too much missing, front wheel, tank and seat and it would be complete. Might be kind of weird to have 3 complete TY350's though..... I have yet to pull the flywheel cover on the white framed TY, I'm thinking there have been some engine mods to it, it runs much different than the 84 stock bike I've had for years. Previous owner didn't have much info on it and he maybe rode it 10 minutes in the 3 years that he owned it. Quote Link to comment Share on other sites More sharing options...
lineaway Posted October 2, 2015 Report Share Posted October 2, 2015 The white one looks like an 88 TY250? Quote Link to comment Share on other sites More sharing options...

lineaway Posted October 2, 2015 Report Share Posted October 2, 2015 The `86 was better, mainly if the rear shock is in good shape. Somebody sure tried to make it look like an `88. Quote Link to comment Share on other sites More sharing options...

Yeah, not sure what they were thinking. I got it from a friend that bought it out of California a few years ago. It's an excellent running and riding bike.
