Thinking of putting a bigger cam in the 700 pretty soon. Anyone else done this?

 

What kind of cam are you thinking..? When I raced motorcycles I had sponsorship from Crane Cams, which is in Daytona Beach and where I used to live. They could take any cam I gave them and then build it up to the specs I needed. Hmmm, I wonder if a Cam may help some in the EFI model....would be interesting.....

 

a friend of mine has a 700 and put the aaen long dur cam in, 40mm carb, k&n, and experimented with different exhausts and jetting. the cam worked pretty well, as he changed one thing at a time to really tell what did what. also, this bike was bought used and was first having a problem with running ( don't know exactly what ), but another friend who builds race engines and does machine work ported and flowed the heads and replaced the valves, for some reason the ones in it were giving them problems during the build. i rode the bike a couple of times with different exhausts and the hot seat seemed to be a pretty good combo with the other work. sorry, can't give much info on the problem part, didn't get involved with this one too much.

 

I have beed looking at Web Cam, Hot Cam, and the AAEN Cam. I have been talking to a buddy on another fourm and he has the Web cam in his. I'm putting a starter & bendix on an it involves pulling the flywheel so I thought while I got that off I would go a head and put a cam in it.[img]i/expressions/face-icon-small-happy.gif[/img] I'm sure it would help the EFI just as much as the Carb models.

 

check the price on the web cam and aaen cam, i think they are the same cam. i know when i bought the 500 aaen cam it came from web. thats who was grinding the cams for aaen. might be little less in price if can buy it from original supplier.

 

The AAEN cam is $399.00 the Web cam is $163.00 plus your old cam and the Hot cam is $169.95. I have E-mailed them and I think I will go with the Hot cam. They make there cams from blanks instead of welding and regrinding the stock ones.Here is the Email they sent me.

Hello Brent,
Hot Cams has been making performance cams for about 4 years. Hot Cams is a sister company of Hot Rods, which have been making connecting rods, and crankshafts for about 13 years. Our cam designer has been designing cams for over 20 years, so experience, and longevity, should not be a worry. Our cams do not compare to any other performance cams, in that we where the first cam company to make there own blanks. All of the other companies until this year, where taking stock cams, and welding them up and grinding them to their specs. Ours are made by us from scratch, no core required. That is one of the ways that we can keep the cost down, because there is no core charge. Let me know if you have any other questions. Oh yea, the cam for the sportsman 700 makes more power through the whole rpm range, and has better throttle response.

 

sounds like a winner to me! let us know

 

I'd like to know how it comes out....after my warranty runs out shortly, I'll be looking to play with alittle things....

I'm wondering if the cam is the same on the 2004 and earlier model 700's as it is on the '05 EFI model....

I have the cam dimensions from the manual, if someone has the 2004 or earlier model, post your specs so we can compare, here is the specs from the 2005 700 EFI Camshaft:

Camshaft Journal Bore I.D.:

elkbow, cams for the carbbed 700 and efi are different. as far as camming an efi you may run into computer and sensor problems. the system in the quads are not like a vehicle where you can remapped them. i can check for you and let you know.

 

let me know, i know the mapping could change or should I say it would run different, wonder if this could be done using a Power Commander, granted its not changing ignition curves, just fuel/air mixture...
