Web Cams 390 grind cam

[96yamahawarrior]

im thinking of getting a web cams 390 grind cam is this a good idea for my stock motor?

For a pretty much stock motor it would be one of the best choices as its a good all around cam. It gives you better performance thru the power band than stock, where most that are bigger go up from there.

where can you buy that at

 

[1998yamahawarrior]

Right off of webcams site, I believe. You may have to call them. Im not 100% sure there as I havent ordered one yet.

 

[96yamahawarrior]

how much are they new?

they are around $140 new plus a refundable core charge (or you can send yours in first) any thing over the .390 will need a spring kit also.

hot cams "dont require" new springs but thats just not a good idea imo, and for an older engine its even more important

I am the guy that emailed you about this cam. I have it because I bought a parts quad last year that the previous owner was going to fix but never got around to it. He dropped a valve in the head and in turn destroyed the head and piston. He was going to rebuild it and bought the cam and a 20 over Wiseco piston (used) from a buddy for the rebuild. He never got around to doing it so I bought it from him. I'll take a picture of it and post the cam for sale on Kijiji for you so you can check it out, I'll do that a bit later today.

I just took a better look at it and it appears to be the 430 grind and not 390. You would need to change valve springs for this cam .
Here is a link to their warrior cams page, it is the second one.

They all require valve springs be upgraded.

Your right, missed that part on their website for the 390. The 430 does require a high comp piston it says on the site. Not sure of the OP wants to go that in depth on his upgrades. I personally don't or I wouldn't be selling it.LOL

 

[1998yamahawarrior]

Post it up in the parts for sale section, Im sure some one here may be interested.

Yeah, I'll let the OP decide first if he wants it or not and if not then I will post it up in the parts section. I really have to do an inventory of my parts and list them all.

Wish I'd have known about it a couple of moths back, I'd have taken the piston & cam. You'll have no trouble selling those pieces.

i'm planing doing the piston...not yet anyway

the springs are always a good idea however for the 390 i would not be to worried about them if your budget didnt allow for them.

i think i read on here that the spring rate is about the same and that the differance is smaller wire size to reduce coil binding. the spings alone would be a good idea to replace on any engine that has a few years on it.
