Aermacchi 175

[Lotus54]

A 75 Aermacchi (Harley) 175 SX came my way. I have been getting it back to usable condition.
The rear rim was really bad, so I (foolishly) replaced with a new Borrani alloy with Stainless spokes/nipples. Front was usable. New tyres, tubes etc. I have some replacement forks that I will replace seals (original tubes were pretty rusty).
No idea what I’m going to do with it, but it has been fun fixing it up.

The front wheel must match the rear. Oh no, here we go...again. Ha. We're addicted. I'm tempted to put the quick change alloy wheel you vapor honed for me on the TR6. But that would mean I would have to do one for the front. Not going to happen..

I have replaced the oil injection hoses since they were not flexible at all anymore and seal on oil tank in frame was bad.
Next I will run it with pre-mix for awhile while holding pump throttle arm wide open.

After running, I will put back on lift the other way so I can swap the forks. The fuel tank is mostly cleaned out and almost ready for Caswell.

Yes- I agree! It is a problem. But is certainly is fun to make them as good as possible.
I could have saved a fair amount using a Sun rim- or just a steel one. But heck- as long as doing it, may as well overdo it.

I ran the Aermacchi for awhile today with 50:1, while holding the Oil Injection pump arm on full. That way I could watch the hose to the intake fill up.
It runs well, but I will need to check regulator- voltage seemed a bit high.

Now on to the forks.
