Hey all:

I love this thread in the dirty section and thought we needed one here too.

I'll start. Pulled the Aermacchi out and got it running (wouldn't start last week because the condenser was toast)cleaned the carb and took it for a quick run for fresh gas. Its currently draining all the oil and I'll put in some fresh after I finish this post.

I was thinking of selling it but its just too much fun and isn't worth what I've got in it so I'm keeping it. I need to ride it more. Next up will be replace the fork oil. :thumbup

Edit: I adjusted the valves and replaced the fork oil. I think it had atf in there and it wasn’t too bad. I replaced with some Honda 5w I had on the shelf. The bike is much happier with fresh engine oil and the valve adjustment. Starts easier and is running much smoother. The oil that was in there was seriously cooked from the melee/engine break in. Probably should have replaced it in the middle of the melee. Tomorrow I’ll be riding this bike somewhere in the western Sonoma/Marin county area if anyone wants to ride.

What’s the cut off for vintage? :laughing
The vintage-ist I have is an ‘86 SRX 6 Yamaha.
It’s got 42k miles on it. Currently getting an engine rebuild (bearings, 5th gear, top end). I’ve prettied up the engine and some of the chassis a bit.
When the engine is done, it’ll be time to re-assemble.
I cannot wait to ride it. It is my favorite.

According to the forum guidelines its pre '85 but 86 srx is good as far as I'm concerned. :thumbup

IMO, it means no disc brakes. Like my 1971 BMW R75/5.

When I see disc brakes, I think of it as a modern bike, like my 1984 Yamaha Venture.

we had fun talking about this when BARF Vintage Cafe was set up ...

my idea was to follow the Antique Motorcycle Club of America’s 35 year rolling cut-off with “any-bike-you-need-to-kick-start” ... :laughing

my ‘85 Evo will be AMCA eligible next season and my fuel-injected ‘88 K75s is right behind it ... :toothless

racebikes become vintage more quickly, and some racebikes have no front brakes:

bikes with big drum brakes will always be cooler than disk brake bikes ... :thumbup

Wait, so some of you say the electric start, front disc equipped 1969 cb750k0 sandcast is not a "vintage bike" worthy of this forum ?!?!

Ouch, i guess I'll just let myself out then.













(No, i don't, i wish, just making a point)

Rode the aermacchi with a buddy on an r50/2. We met up in Petaluma and rode around west Marin and Sonoma counties. I think we did around 150 miles or so. Super fun ride but the aermacchi wore me out today. We were on some goaty roads at one point and my carb actually vibrated off the manifold. Later the bolt that holds the points cam on the shaft that spins it, came off. I had the cover plate off so I could mess with the timing. Luckily one of the bolts that holds the points plate did the trick and got me home. Fun day!

How about both, like my 1971 BMW? It has the 4 speed tranny with the kick start, but also has electric start.

Oh, BTW, having more than four gears should also disqualify a bike from qualifying as vintage!

And if it has an electronic ignition. It must be points.

Whops!! I overdid it here, I put in a Dyna 3 electronic ignition in my BMW when I had it dual plugged. It also has a GPS speedometer and an electronic tachometer (Harley tach--made in Japan!). It's mixed high tech and low, but it sure runs great!

we always give the guys who show up on BMWs for our vintage rides a hard time for their generally-problem-free “cheater bikes” ... :toothless

Checked valve clearance (X 24!) on a friend's 1979 Honda CBX. Now waiting for the valve bucket compressor tool and assorted O-rings and seals.

:hail

sooooo cool! :thumbup

guessing shims, because I don’t see followers ...?
how many needed adjustments intake/exhaust?

I graduated high-school in 1979, so the mighty CBX was one of the bikes I drooled over as a 17 y/o ... :laughing

Yep, shims. Luckily they are above-the-bucket type so no need to pull the cams! Only one valve was tight, all others were at the minimum. But we'll go ahead and re-shim them all to the loose end of the tolerance. We had the wrong compressor tool so could not do more than measure clearances yesterday.

This is the bike we recently reinstalled the carbs on, after getting them back from the rebuilder. It's a two owner bike with low miles that has the factory sport kit lower bars and rear set pegs. Very cool indeed!

how are the cams driven? Looks like one chain from the exhaust cam to the crank and another chain between the cams? :dunno

Cool! I don't know much about those bikes but thats a lot of valves to adjust!

Found an engine diagram online. Looks like two cam chains and some kind of primary chain too.
