Greetings! My name is Andy and I live in Virginia, USA. I recently acquired a 1973 Triumph Bonneville T140V, 750. This was a true barn find, as the bike had not been started in something like 40 years. I was gratified when I gently pressed down on the kickstarter and the engine rotated without much difficulty through it's full kickstarter travel. (I have not yet attempted to actually start it). However, somewhere along the way, I have managed to mess that up. I have changed out all of the fluids and filters, cleaned and rebuilt the carbs and basically put as many things right as I can without cracking open the gearbox or chaincase, which didn't seem necessary. Now when I apply pressure to the kickstarter, it moves down easily to the point where it should begin to turn the engine and it hits (what feels like) a solid mechanical stop with no further movement possible. When I try to rotate the engine by hand using a ratchet on the crank (on the left side), same result, hard stop. I installed a new clutch cable, but the clutch does not seem to be functioning. When I put the gear selector in first and pull in the clutch lever, the rear wheel will not spin. But when I put the gear selector in neutral, which is not hard to do, the rear wheel rotates freely. It feels like the transmission is engaged and won't release, and using the clutch doesn't help. This seems like a simple "user error" type of thing. I haven't done anything to the engine, valves or transmission, and I know the system rotated just fine when I began cleaning things up. Any ideas? Thanks for taking the time to consider my issue.
Greeting from Lincolnshire. I can't help you, but there's more than a few here that will point you in the right direction.
From your description, it sounds like the clutch is seized which is what I'd expect TBH if it's been stood for 40 years. Was it definitely in neutral when you tried to kick it?
Thanks, everyone! Welcome indeed. Thanks, Pegscraper, I double-checked on your suggestion and now I'm sure she's in neutral. Thanks for the response! I read some of the other posts on the forum and made good progress by gently rolling her back and forth until the clutch plates loosened. That issue now seems to be resolved. The kickstarter is functioning as it should, but the old girl still isn't starting. I suspect electrical issues now, and I've begun tracing the spark. Thanks, again, everyone. I'll keep you all posted on my progress. Let the adventure begin...or continue...
hi andy help me here. does the crankshaft now turn successfully when you use the kickstarter? without touching the clutch lever? i dont have enough information. im trying to ascertain whether the motor is seized.
