Looking to get some more power our of my Warrior, so I was thinking of puting a Web Cam (.390) (80-161) in, and a valve spring kit (VC-Y25) from www.webcaminc.com. Am I going to have to run a higher octane of fuel with this combo? Is it going to make a big difference in preformance? I already have a Pro-X piston in my bike (.25 over bore I think), so I'm assuming I won't need a new piston. This very hard to install yourself?

 

I don't know I was woundering the same thing.I do know if you go to http://www.geocities.com/foxracing00...ndwarrior.html its a really cool web site that has alot of warrior stuff if you go to the lattestnews section they have a setup that has everything from cam/valvesprings/and piston.On it, it says it eats 400ex's alive it takes the piston and you have to bore it out 30over but it is worth it to look into and it has the price of everything.


I was woundering if adding that piston it added alot of power????

My ride is a
89 warrior
sunstar 12t front sprocket
909 handle bars

 

Just the piston in itself? I really couldn't tell you. When I got my Warrior it wasn't in real good shape, so I had it bored out and had that piston put in. So, without riding it before before having the piston in, I have nothing to compare it to... So I couldn't tell you...
