What's holding your chain to your clutch pushrod? Is it just layin' in the ditch?

Interference fit through the arm with a teenie collar to keep it extra tort. It's under tension from how I hasd to engage the clutch arm to get it through and bolted up but still has specified slack.

I've now got good spark on both plugs and have had her turning over. It's getting the M35 where the bike likes it next. I've tried 3.5/3.0 turns on the low speed needle on the carb and it's coughing through the carb and has fired but not idled a few times.

Take it back to 5 full turns and see where we are. Learning what she likes to start is key, and then checking for intake leaks is followed closely after!

Today has been mixed!

Got her timed and bolted down after giving my mag and lid a slight grind down to clear the fins.

After much wangling with the carb, got her to fire up a few times only to rev pretty damn high and die... classic intake leak. I don't have anything to test it but I also don't have a proper spanner to tigthen the plumber fittings up..

My theory is I haven't gotten them tightened half as tight as they probably need to go to seal. I'll make a spanner tomorrow and see if we can't get her to tick over nicely!

Having tried and kicked the bike til my foot is bruised with a few fire ups but not much else to talk about, it's time to admit I have a big intake leak! Currently in the process of milling a big ole spanner to suit!

Got the old girl out in the sun today for a little while. And yours truly looking like a dickhead. FT my UL

you sure you're not looking at a jetting / float problem - blocked stuck . I checked the intake with a shady tree sealed blanking plate, tire valve, cheapo dash fed tyre inflator and usual soapy water mix. Not ideal but shows any significant leak. Bench checked the mag to see spark is constant.

Pipes look long to me as well. Opinions aren't quite like assholes, though. We only get one each of the latter.

looking from this angle now, I'd say the same.
I'd say that length of pipes are more suited for a chop with a long front end.
But, that's only my opinion.

Guys,

Don't need to justify not liking them, it's my personal preference, they're a talking point, and that's what I wanted. Plus they're 60 years old... original chrome... I can't not use them, would be a travesty to life itself!!

If you've been following I've got an issue with the bike not wanting to idle. I don't think it's an intake/air leak, so currently trying to find what's up. I'm frustrated, I won't lie... but I'll get there.

To do list: Headlight, rebuilt. Shim front wheel, chain, wiring, rear light.

Excited to get there!!

Two fine looking scoots! I couldn't part with the flatty. The UL engine has been my favorite, forever.


I really like the profile and the shape of the fish tails, I think the length works. One comment is that I would run a brace up from the bottom clamp to the top pipe. You have to much distance past the frame clamp at least if you have bumpy roads.

any progress/ideas on the tick over issue?.

i'm not sure the length of the fish tails or for that matter how many promo T shirts you own, what brand beard wax you use or rum you drink is the cause of the issue.

Maybe verify all the bits in your carb are correct
i helped a guy out with a knuckle that he'd just bought from a guy in Rimini
wrong carb ,wrong nozzle, loose choke, broken float
Not much i could do.

I've made it more than solid enough not to need a brace! there's method to the madness with positioning. The rear pipe can't come loose, resting against and tightened on top of the clutch arm nut, so it's supported there.

Front rear piece has a huge bolt and bracket and is super solid. I'll add another there if it gets wavy!

I've done a leak test, all negative, I've gone through the carb, no issues with it at all, I've changed the mag to another I have which I know is SOLID! it runs, revs and dies.. I'm a little at sea.. not sure what else it could be.

Any restriction in the fuel line or the needle and seat?

I've made a discovery.

I've got it running several times, almost fully choked, you know one crack open to start them.. it revs... and then when I open the carb it dies.. NOW... that says air leak yes? but my manifold is definitely not leaking.

So... maybe the heads need a bit of a torque.. that's the only other place it can leak air right?! but i've got it to run!! and it will run consistently.. but opening the choke kills it!

I'll bet you my last cookie the head bolts aren't torqued up. It's huge progress! I'm elated even though it's revving with the carb just one off shut choke!

You mentioned initially that the motor was rebuilt, did the builder test run it?

Yeah was heat cycled and bench run, but nothing has been retorqued from what I can gather.

Are you leaking air at the throttle shaft bushings?
