stock raptor cam

[Family Dad]

Does a stock raptor cam have anymore lift and duration than the stock cam in my 5hp I/C engine? I can get one cheap but dont know if I should bother.

I'm pretty sure that they are the same cam.

So what is the difference between a raptor and a stock 5hp flatty. Are the rods better?

From what I have read, the rod and the piston hold up to higher rpm's.

No, the raptor cams are the same.

How many rpm's can a stock raptor rod handle? 6000 would be good enough for me.

i threw a raptor rod like it was plastic. spend the extra money for a billet rod. I see alot of used ones on karting.4cycle.com for about 30 bucks


Anyways, back to the cam. Its a stock cam. its has a bronze exhaust guide though.

Thanks for the advice, I will go with the billet rod. Now I need to find a good crank shaft for it. The one that was in it is threaded for a pump. It has a 5/8 shaft so maybe a machine shop could machine a keyway in it for a decent price. Has anyone had that done?

Yellowhand will do it for the price of shipping.
