Hello, I have a chance to purchase a 1973 TX750. Low miles (5600) in good cosmetic condition. Seller says the engine is locked up. He does not know if its from sitting or mechanical failure. I've read about the issues with engine failure and seller has documentation for fixes concerning the oil pan and cam chain tensioner back in the day. So I know I'm looking at a probable rebuild, but wondering what I should focus on and where the failure most likely occured. Appears the bike was last registered in the early 80s. Any advice would be helpful.  |

Hi, for sure I`m not the one here who should give you advices as I`ve never seen a working TX, but I`ve been working on one for 2 years now so perhaps I can tell a couple of things you may wanna consider. It all depends on what you want to do with the bike. If you want restoration, this bike, apart from the mufflers and the handlebars, seems original. If you want to use it regularly you will need to make it reliable. The deep sump and the adjustable balancer is a plus if ithas it. Having these makes me wonder the bike has a replacement engine, which was typical back in the day, many bikes got `74 engines when the original blew up. You can recognized these based on having ~kickstarter~ written behind the kicker, and the lack of engine number. For the stock engine the engine number should match the frame number. If it`s stock, you will face the issue of the leaky magnetic oil filter cavity which floods the points even after a few thousand miles. Lasting solution for this is possible by rerouting the oil lines, which was done on later engines. For this you will have to split the cases anyway, so the engine being locked is not really a big issue here, as you can find engine parts for cheap on ebay. So it depends on the price and your plans on the bike. If you can shoot more pics that may also be helpful.
Hoe that helps,
Greg

Starter chain probably lying in the bottom of the side cover binding the crank.
