MB5 dudes - share your jetting!

Trying to get jetting down on my MB5. Stock cylinder with a MLM putt putt and VM20 with high flow air filter. Currently have a 135 main jet and 17.5 idle. Topping out at 48mph. Stock gearing.

Curious what others setups are like and the top speed they are seeing

Re: MB5 dudes - share your jetting!

i've been wondering about this myself. I have a 70cc kit and vm20 on mine. Jetted at 165 seems way too rich, bike dies as soon as i rev it up.

There's a really good chance that's an MB8
