New to bansheehq. Bought my first banshee last october blew it my first ride out. And rebuilt it completely stock. Hotrods stock stroke crank and oem everything. I got t5’s on it vf4 reeds. Pro design coolhead 22cc domes. 2 in 1 carb. +4 timing. Mattoon lockout clutch with direct drive cover. I got sick of it i need something more powerful i was getting wrecked by ktm 450’s quads. So i tore my motor down. I wanna full build the motor now, want some ideas. I do all kinds of riding. Dunes, trials, hills, drag races. But mainly trials, so i wanna keep this trial friendly. Im going back to dual carbs also. Ima be buying a forged 4mil crank. I just wanna know wat the best top end would be for me. I want something reliable that wont over heat or blow from long rides. Ive read alot about the 421 serval 4mil build. Is that the way to go to get heavy power but keep it trial friendly?
