Roller weights for a Yamaha aerox

What roller weights would be best with a Leo vince zx exhaust on a Yamaha aerox?

Cheers

 

id say 6 gram but depends all bikes are diffent

 

Can you put an exhaust on without changing the rollers?

 

Apparently aerox's will respond better to light rollers but the general rule is when you put a performance exhaust on, drop weights by 1 - 1.5 grams, and upjet by 10%. If you dont drop roller weights it will be shite performance all round, and will do hills at about 10 mph lol.

 

Ok, might try 4g? Where I live there are no hills so that won't matter too much haha, cheers

 

You will probably find 4g is too light and it will rev but go nowhere, I would try a 4.5 or 5g, but dont forget to upjet 10% ( usually from 62 to 68)

 

Does 0.5g make all the difference?:O also is 62 the standard jet?

 

The normal jet for a standard 12mm gurtner carb is 62. and yes .5 grammes makes a difference (dont forget it's .5 multiplied by 6)

 

I'm running 3.5s with yellow clutch springs and a yasuni z exhaust and a 70 jet and my pull off is still terrible and ideas
