Most of the problems were from overheating IIRC. I don’t know if that was because of riding them hard but I suspect it may have something to do with it.

Sure you're not thinking about the TX750? They had a funky exhaust "balance tube" thingy across the exhaust ports, which no doubt caused hotter running. And the balancers on the 750 whipped the oil into a froth, which didn' t help either.Most of the problems were from overheating IIRC.

I remember reading that! It was a great story. The engine on the 500 top end was torn down and reassembled on the road.There's a link on this site somewhere to an ADV Rider thread where a bunch of young guys set out on a cross country trip on a bunch of dirt cheap old UJMs, one of which is a Yammie 500. As far as I recall, the cylinder head cracks do not pose any operational issues.
A single carb on a 180 degre crankshaft twin may cause issues with uneven carburation, due to the 180/ 540 degree spacing of intake events. I read that Norton struggled with this on their P86 Cosworth Challenge prototype racer development into a street bike in the 70s.Currently building single carb manifold. Have no idea if it will work, therefore just using pvc for now. Pics later.
Had my first encounter with a very rude buyer yesterday for one of my goldwings. Nitpicked every inch of the 40 yr old bike … anyway…. I sent him on his way
Noted…. I will probably end up buying the carb kit( $400) after jumping through all the hoops.A single carb on a 180 degre crankshaft twin may cause issues with uneven carburation, due to the 180/ 540 degree spacing of intake events.

I hear you. I just installed a new battery and starter switch. Good news …. Starter works.What’s wrong with the set you have IIRC those were 32mm? Step one is evaluation of what you have and what you will need. Don’t go down a rabbit hole before you even know if what you have will run.
If the PO says they're rebuilt, why not give 'em a shot? Nothing to lose 'cept a small gas puddle on the ground. Seems to me that would be the quickest route. Pour some gas in 'em and hit the starter.The stock carbs we’re supposedly rebuilt by the po but I’m not sure I’m trusting that.
I just opened up the carbs and they look Pretty good! Let’s see what happens.If the PO says they're rebuilt, why not give 'em a shot? Nothing to lose 'cept a small gas puddle on the ground. Seems to me that would be the quickest route. Pour some gas in 'em and hit the starter.
