stage 2 hotcam

[mad4106]

i have a stage 2 hotcam in my bike rite now with a standard bore with curtis sparks exhaust and 11:1 high compression standard piston?! im still getting beat my stock 400. I want to know if the stage 2 cam is meant for bore kits such as the 416 and 426 and not a stock bore?!

I think the standard piston is 10:1 compression. I don't see how you're getting beat by a stock 400ex

9.1:1 is stock comp. the stage 2 should be alright with 11:1 no matter what the bore really. i guess it is hard to say, could be jetting poor ring seat, alot of different things.

actually i think the stock is a 9 to something compression

the stage 2 is a fine cam to run with a stock bore especially b/c u have a higher compression. but it would add more if u had a bore job.

things like this come up all the time. I would just swap bikes with him and see who wins b/c he might just be a better rider

Stock compression is lower than 10:1. I think its actually in the 8.5 to 9:1 area. Drag racing has to many variables to just assume you would beat a stock 400 because you have some engine mods. What surface are you riding on? What kind of traction are you both getting off the line? Who is getting the "holeshot"? Is one rider heavier than the other? Is your clutch slipping? What gearing are you both running? These are just some of the factors.

I'll buy the stage two cam if you pull it!

I might be wrong, but I'm not sure the stg 2 is a good cam for a 11:1 stock bore. I think there is not enough CC's to suck the air needed to get a true 11:1 compression, and your lift&duration is too long and let air goes out before the end of the stroke. I think your cam overkill your motor, you should drop to stage 1, go bigger bore or go higher c/r at least 12:1

I'll go bigger, at least a 416 11:1

not necessarily. i would look more into doing a compression check, really taking a look at your clutch, or the rider mod. either youre not making as much power due to wear, or you're not putting it to the ground.

Do you think if the clutch was slipping it would make you lose power? Sometimes when I get in 3rd at high revs and I shift to 4th and push the gas it revs out then I have to let go of the throttle and then it will like shift.. When I put on my full exhaust and air filter I really didn't notice a difference in power like I thought I would be able to pull wheelies in 2nd gear and for some reason I can't I'll pull in the lever and pull back and it does't want to come up

Your clutch slipping will not cause you to have less power. You will still have full power, it just wont get transferred to the rear wheels. If you are noticing the motor rev out but you aren't gaining any speed then yea the clutch is bad.
