Ryguyty250 Posted April 20, 2023 Report Share Posted April 20, 2023 Me and my friend are restoring what we believe is a 74 ty250 based on the design on the gas tank but we’re having a difficult time trying to find info on the bike. What’s the name of the engine and/or do any other bikes share an engine or parts, what’s a good place for parts or info?? Quote Link to comment Share on other sites More sharing options...
tony27 Posted April 21, 2023 Report Share Posted April 21, 2023 The 250A engine & frame numbers start with 434. Things like pistons are common to a few bikes but if you buy off eBay make sure to not get anything with the 311 number as they hit the crank at the bottom of the travel, luckily Wossner make kits that a lot of companies stock Clutch sidecovers are unique to the TY250s so the gasket is has to be the right 1. Most engine parts are the same for all the twinshock 250s so they're easy to get Inmotion, Yambits & TYtrials are probably the best places in the UK for parts Partzilla is a good reference for what parts are common to other bikes, click on the part number & it lists all bikes that use the part 1 Quote Link to comment Share on other sites More sharing options...
Ryguyty250 Posted April 24, 2023 Author Report Share Posted April 24, 2023 Thank you so much, that was really helpful and I can’t thank you enough. The only website besides eBay I could find that sold parts was bjracing.com Quote Link to comment Share on other sites More sharing options...
