Can I use a 5pin vespa regulator?

feeds in are 1) unregulated AC in, 2) Regulated AC out, 3) DC out, 4) unregulated AC in, 5) ground.

My lambretta stator has 1 AC out for the regulator. Can I add a wire to it so it connects to both regualtor in puts or will this drop my watts?

Tx

Re: At Last!

I've used Jetex, many dellorto and Miikuni. I'd say it comes down to the quality of the specific production run. They all have part suppliers and quality standards can vary by who is running a machine on any given day. Or who things are outsourced to. A company I worked for outsourced manufacturing....

Sealed bearing on crankcase side?

This picture was posted on another forum. Someone put the bearing in with both sides sealed. BeAring is pregreased. As advertised this grease is supposed to last for the design life of the bearing. So why do we remove them? Is this not an improvement over original and relying on case oil getting int...

Re: Advice please

The issue is the air box restricting airflow no? That’s a relatively big bore, carb, and exhaust. Correspondingly needs good airflow. I’d try a rubber elbow with a foam filter on it, removing the air box to make room. See how your jetting goes then.

Re: Tameni GP crank needs small end shims in an Indian GP 200?

Yes. It’s why I’m asking if the tameni crank is shimmed on the big end. It does not seem to have a lot of side to side movement, but I hope to hear from someone who knows

Tameni GP crank needs small end shims in an Indian GP 200?

Hi, I measured the big end float when the crank was on my bench. Was 0.5mm

That is a big end shimmed, yes?

Or no, I need to shim the little end

Re: My latest barn(ish) finds

And then again sometimes an oddball pops up. A scooter came up for sale locally advertised as SX 200. But on the pics it looked like a bitsa. It was actually a TV 200 (or GT 200 in UK terms). At $6k AUD, I thought it was a great buy even though it had been a bit bastardised. Probably needed about $...
