I am newbie. I have been tuning 2 stroke minarelli's engines. I also had a 150 maliguti warrior that I wrecked. I need direction with the gearing in my 4t super 8. I have 50mm big bore kit, main jets,racing cdi, mallossi delta clutch and variator, r next pipe, 1500 torque spring, 4,5,6 g rollers and k&N filter. I am looking for speed for a dailey driver. Can't go to a 150 cause I got arrested with the 150 maliguti. No drivers License due to drunk driving. Sober for last 3 years. I told you guys that so you would not say get a 125 or 150.Back to the gears. What do I need and where can I buy?
