Hi mate I think you will find its trial and error what works in some one's bike may not in yours .you Probs have to try a few combos but if you increase your jet you may need to increase your air flow .you no how to do a plug chop ?

First mate please read my post in your thread that you already started, that cylinder is a load of shit and a Chinese copy,
if you want to get anything out of it you will need to also upgrade your exhaust.

Anyway first you need a carb of at least 17.5mm. a second hand 21mm dellorto would work well. then you simply increase jet size till your plug chops are a light coffee colour.

oh and you WILL need to upgrade your crank
