I was wondering if any one has ever built or been around one of these engines. Its a 4 mill with 65mm bore cub . I was just wondering how they run.

It should run real hard. I had a stock stroke 68mm (392cc) and it ran good. Ran it on toomey's and shearer's, definately better on the drag pipes. I had 34mm mikuni flatslides for carbs with stock reeds. It was a lightswitch but on the pipe was a heck of a runner. The 4mill stroker with net you some torque and more power down low. It will still be pretty touchy though.

I was thinking about getting into drag racing. The track has a 350 to 385 class. I have a 4 mill mx hardcore ported by herr jugs,stock carbs, stock airbox, DMC pipes i raced last year. I didnt lower it or even take off my skid plates and nerf bars. Its a 500 FT dirt track, BBDR u might of heard of it. The best i could do was 7.5 at 80 MPH, but a coundnt get off the start without riding a wheelie. The guys winning that class run 6.4 at 90MPH.

are you going to change up your suspension also? just putting in a bigger motor is not going to help you out escpecially if your having problems wiht your lil stocker motor now.

 

try setting up your suspension better and droping as much weight as you can first?
