I got a new web cam 450 grind, will I have to get new rocker arms, or can I leave them stock.

 

I'd ask WebCam.

Their more conservative cams are drop-ins, the more radical require valvetrain modifications.

If their website is up (www.webcaminc.com), I believe their catalog provides information regarding valvetrain recommendations.

I was in the same situation with my 300ex. I ordered a web cam but they said i had to buy rockers so i didnt have enough money to buy them both. Just call them they will tell you everything you need to know

 

Is the cam you bought the race cam or the direct replacement? If it is the race cam you will have to replace the springs, valve guides and weld the rocker arms, if it is the other it is a direct bolt in. I would call web to get all the details though.

 

How fast is your quad with the piston rev kit etc. because I am going to be rebuilding soon and I would like to know my options. Is the piston stock mm or did you go with a larger bore? Can you run that high of comp. on pump gas? Thanks.

 

The piston is a 10:5:1, but I kept the same bore. The power is awesome, but the base gasket didn't hold so now I am leeking oil. So I have to take it apart again. It seems to run perfect with 92 octane.
