RagunCajun Posted August 30, 2013 Report Share Posted August 30, 2013 (edited) Good luck trying to get the bike to hook with a ported 4mil. It will be a fun bike though with a broad power band. Maybe budget in about $300 more dollars to get a good pro mode trans from redline. An undercover slingshot from vito's would be nice. You can run more weight than needed and have a very light clutch pull because you dont have to use 6hd springs. If i did a lot of trails, i would do suspension before more power. for a 4 mil, you can get your juggs ported than run a different piston so you dont have to use a spacer plate. The person porting the cylinders can tell you the best domes, pipe and carb combo better than any of us can. There's no way id run a 4mil crank without a good port job on it. I like to make any engine combo i have very efficient. My old 4mil was very smooth on power delivery and had good top end for a play bike with cpi's and small 30mm carbs. A properly set up 4mil play bike will hold it's own against your typical 450/700 in a drag race(assuming you can 60' your banshee and drive).
