Many of you asked for a 2 stroke version of our recent (4 stroke) carb sizing vid we did, so here it is! 🤘 *It’s worth noting that rotary valve engines run smaller than reed valve and piston port. A 100cc rotary valve averaged a 19mm carb and 200cc averaged a 24mm. Even the RG500 race bike only runs 26mm with 125cc pistons which for a race bike is relatively small*..#motorcycle #honda #suzuki #2stroke #2t #2smoker #mx #mechanic #carburetor #tuning #howto #yamaha #kawasaki #ducati #bmw #harleyda
