Main jet change necessary?

[fv07031986]

At that time I could not find any Suzuki CS80 it was so rare as a hen tooth in UK! And never found a one in 10 months so I gave it up and I went look for a CS50 so I will modified it to make it go a bit quicker like the CS80 do. March this year I have found a Suzuki CS50 1982 Roadie was left side of scrap yard in brambles at Liverpool and bought it for £100 and brought it 250 miles to home.

Today finished my restoration and went rode it, I was disappointed that the CS50 barley reach of 29.3mph probably why I weight 14 stones!

I was wonder if change the main jet of carburetor my is currently at 85 would it be worth if I go for 90 or 92? Or just waste of money and time?

Do the two stroke like a performance air filter? What about high flow exhaust does it work? Because I have never own a scooter before so all this is new to me. I was hope to reach max of 36mph is good enough for me go to work through the countryside.

Any advice would be a appreciate.

thanks

It would make zero difference your best bet would be to lose weight and it may go a bit faster.

OK, try to remove rear rail, box, spare wheel not worth in use again and my weight gain!

I would do a compression test, you may need to replace the piston rings or a complete piston set

Two strokes don't like disturbed air. I would leave the air box.

A performance exhaust could give a fair increase in performance. But I doubt you could find one.

The speed is most likely limited by a restriction ring in the variator. It stops the two sides closing together. This is your high gear.

It will affect your insurance if removed.
