CUL8ER · Aug 29, 2005

Hey!
Looking to mabe swap out the 08 cam for a cam that gives more peek hp and a little less torque.. have to much torque now

What is the main difference between the 08, Lx1, G2, G3 cams? I have found some specifications on the cams but i don't now if its correct?

08cam 264 degrees in lift both in and ex 10,8?
G2cam 272 in 262 ex lift 10,5, 10,4?
G3cam ?
LX1cam ?

What cam will be best for me if looking for much hp?

// THx =)

i think only one man on the site has tried more than one of those cams and that's 'supermototeam'. he had the G2, 53 and i believe the lineweaver LX2 cam.

PM him direct-i'm sure he'll try to help you.

you could try retarding your cam 5 degrees and see what it does? i believe it may make it a little flat at the bottom and crazy at the top.

if you want top hp on large displacement i would take x1.

i think 288 degrees and 10,80 lift.

For top Hp; go with FP exhaust system and bigger valves 37-32,and X1 cam,Hp enough.

On my 650 with Fp 65SAE HP + when you take x1 +bigger valves you must get around 70HP on the backwheel,but!!!!!! you will loose a lot of power on bottom.

Hopefully you have something on this information.
greetings Madero.

X2 Camshaft / KTM

For what it may be worth and with regard to the camshaft banter of late may I present the following for reference:

Long Stroke KTM 450. (89 mm Bore x 72 mm Stroke)

Blue = Stock
Red = Lineaweaver tuned FCR 41 (including jet kit without pump shot)
Green = Lineaweaver X2 camshaft in addition to FCR 41

Nope, said engine is completely stock internally with exception of the camshaft.

Could you pm me the spec for both x1 and x2 cam, so i could deside what cam that suits my need best?.. but i guess i maby want x1 =) this will be used in a -05 or -06 650 havent desided yet...

LRX1 = 284 / .414" / 106
LRX2 = 272 / .407" / 107

X1 requires one to use an open exhaust.

LOL

Nothing that exciting.

Since said engine has such a small bore the valve area is limited.

Truthfully speaking and in my opinion it simply was not a cost effective move to squeeze an additional couple of ponies out of it and as such I opted to not enlarge the valve area and / or increase compression via a domed piston.

As it currently stands the power per dollar value is pretty good. I honestly did not wish to tip the scale in the opposite direction.

Hope all is well.

Best Regards,
Dale

I have a full titanium Akrapovic and taht little thing that lowers the DB in the silencer is removed.. is that good enough? Or is there any exhaust that is better? Have heard that FP should be good...

Your Ak system should work fine.
