Option 1
A1/A2 RW Cams
Intake lift .433 in. duration 267 degrees.
Exhaust lift .406 in. duration 278 degrees.
Option 2
web cam 109/110
Intake Lift .425 in. duration 260 degrees
Exhaust lift 395 in. duration 256 degrees

The web cam in take is not as long or as tall but is SO close it does not matter
The web exhaust is DANG near stock. just a .10 higher and its acutaly shorter duration..

BOTH will have the 11:5.1 piston

Belive it or not, both come VERY close in price, the webcams cost less but its regained by the shim under buckets, the rw cost more but you save on the springs..

is there any real differance in these sets??
I am leaning toward a1/a2 as it seems to be a larger differance but what do I know....
I ride trail usualy in 4/5 gear 45000-6000 rpms...

 

i have the a1/a2 and love them, but never ran the webs so i can't compare. I have the shim-uder conversion as well.

as for the shim-under conversion, web recommends it for any cam lift higher than sport, and they'd say use it with those RW cams too. but I know people who run even higher lifts than these with stock bucket set-up. the shim-under only offers the security of knowing that IF the unlikely event of a valve dropping from stem breakage or spring breakage, the shim is trapped and not able to escape and cause further damage from flying around. my .02 is that since your dropping all the cash for the upgrades, blow another $100 for the conversion and security, even though its purpose may be a little overrated in some opinions.

more to chew on - since you spend most time in such high gears maybe you wanna consider full race cams. the staggered cam set-ups you listed are great for all around power - more top than sport without the bottom sacrifice off full race, mega midrange, but if your bottom is of no real significance then go full race and look at some of the pami cam grinds too.

 

I really dont want to lose the low end.. There are times I run lower rpms.. on tight trails and such..My DS stops rpms at 7700 with the rw box... I want MORE power so I can run 9 grand then that opens the speed more or I can run taller gears. But I like the way the DS brigns the wheels up and I really dont want to loose that..

 

sweet dude, you want what i wanted and I'm happy i got it.
these cams/springs make great power past 9K, feels like it drops off after about 9.5K, haven't dynoed yet to know for sure, but I rev to 9K constantly and it likes it!
fyi - my gearing is 15/40 w/ 20" tires and I peak out at 9400 in fifth 87mph on gps - pavement. I weigh 250.

 

sweet is right!! I weigh 255!.. Ok what setup did you go with?? Exactly?? I wont get the porting and polishing. Its kinda spendy...

 

Ok,
I have decided on the Stage 2 with the A1/A2 cams. I am NOT going with the shims under buckets..... Now its just geting the old motor ready for new parts..

 

Good choice on the set up, you will like it for your type of riding[img]i/expressions/face-icon-small-smile.gif[/img]

 

for your riding you will like it.
