The Tilly's were available on lots of things for many years and most parts are still out there. Google is your friend.

Also, research "pop off" pressure while your doing it. It wasn't correct from the factory and a little effort will bring big benefits there.

If you have already had the engine running there's probably no reason to pull the top end just now.
You have just honed the bores with the rust that was in there and if the rings didn't stick unless your prepared to bore and install new pistons it's probably going to be "as good as it gets".

I know the feeling. It's hard to stop yourself (impossible ?) from just wanting the reassurance that the thing will run and be what you want it to be.

So, for a brief moment you felt like you were 18 years old again ?

(Don't worry, we are all chasing that dragon here)

The reason I tried to run it was to see IF it would and then I couldn't put it in neutral with any throttle on. No clutch. No throttle, it died. What a pickle. Oh well it will run soon enough. As far as feeling 18, I always feel like I'm 18... in my head

Boy your lucky.

I'm only 18 for about 20 minutes at a time. More or less depending on how many laps we're doing.

The best piece of mind you could give yourself would be from removing and inspecting the transmission. Welcome to the forum!

I have the clutch completely removed, so I'm right there. Few more bolts and she's out? I can look for obvious wear but I'm in unfamiliar territory otherwise. Gearboxes aren't my strong suit. I'll have to study the FSM to see what's involved....



Found an old ugly scar when I opened the primary. See the screwdriver pointing to it.

I'm more concerned about the short studs on the chain tensioner, than what appears to be a good repair.

Interesting nylon primary chain tensioner too. Yes, a few bolts for the trap door, and a large nut holding on the right side sprocket on. Grab the clutch gear with your left hand, and give the main shaft on the right side a few raps with a rubber or rawhide mallet and it should pop right out. Post pics!

Another fun thing to check is the flywheel rim through the timing inspection plug hole. If you find a series of numbers stamped into the rim, you might have a set of stroker wheels hiding in there.

The nuts are only on a few threads. Just my way of keeping track of em.
