Hi, ive just bought a gt125 2003 and was wondering if anyone has fitted a gt200 barrel and piston, will it fit? and how much more power would a polini or malossi 210 kit produce? and then there's the question of jetting??? any help would be much appreciated. regards James
i had malossi one, 210 cc. doing well so far, tend to get hot easily as fan coming in more often in summer than original cast iron set. no need to re jetting carburattor on mine. checking a spark plug for a sign of imperfact burning. need very good battery or it will not turns the engine. i changed my to bevery 500cc battery.
