i was just wondering how many horse power a 1997 sx 700 has. i have one with a exhaust can on it. and my friend just bought 2 1997 sx 700 today with only 1300 miles for $2000 i was just wonder what stock hp is on these sleds thanks
 
yamie is right. but with some porting, shaved head, pipes, reed notch, bost bottle and jetting you could see in the 135-140 range depending on what parts and tricks you do. but rember thats crank hp. a SX chassie is more efficent at getting hp to the ground then a long travel rider foward sled.

I thought that with the free mods and triple pipes you would be close to 140 without porting? Maybe im wrong how much power does a mild port job give you?

I have n slp can on now. Your saying it has less hp?
 
YES, cans sound good but they run better with the stock ones.

If someone wants the sled to sound good there is only one way to go in my opinion.....PIPES ;)!

I have benders on my 600 ( a little loud for my taste, it can get kinda anoying) and SLP's on my viper (they sound awesome)

Depends on conditions, gearing, lug height, clutching etc. I have seen close to 160 kmh on my 98 xtcp geared down 1 tooth with a 1.5 track. (dreamometer)
 
With everything stock, except this... The stock can drilled out, the head gasket thinned to one layer, reed spacers, and the top gear is a 22 instead of a 23, my 98 700sx will go about 108 on the speedo, that's about 103 or 104 on my GPS. The lake snow was frozen over after it got cold after a day of rain and then there was about 3" fresh snow over that. It was about 15°F, oh yea, it had a slight overrev, it was running ant about 8700 to 8800 then. Since then I have added pipes and a 136 skid, but haven't had time to test it.
 
Tony's right on with the HP.

Dyno Tech:
Max Hp 111.8 at 8250...stock

Max HP 114.7 at 8500...Bender Can

You can achieve great perf on these by doing some minor things:
-Stock exhaust canister mod[tech pages]
-Carbon tech reeds in the stock cages
-reed spacers...an absolute must!
-thin head gasket[tech pages]
-clutch it to run no less then 8200 or more then 8500
-1" light weight track

These 700SXs will suprise a lot of people on how strong they will run...even without going to tripple pipes!
 
ok i just wanted to make sure of speed my sled has a bender clutch kit and bender can. it was reving 9000 rpms at 105mph so i took secondary off and tightened it up it was basicly sitting on there with no pressure. i put it back together and it seems 2 take off faster and top speed is around 105 -110 on spedo at 8500rpm. i was wondering if i put stock helix back on would it be faster or slow it down. i dont know much about clutchin on secondary
 
As far as your clutching goes you will have to provide more details as to what it has in it right now for the clutching guys to help you out.

1] present helix [there should be a Bender # scratched into it somewhere]
2] colour of secondary spring
3] current twist the spring is installed at[for example:spring at one end in hole # 1, other end # 6]

You can start with that info for secondary

If your sled is presently running at 8500 RPM from the time you launch it at wide open throttle until you let off the throttle after your speed run...that should be good. That is what you call your "Shift RPM" and on your sled approx 8500 is what you should be trying to achieve.

the spring is black i know i have it in the #6 on out side i dont know what it is on inside i will look tomarrow. but what is the difference from the stock helix to a aftermarket. is i just meant for take off or for top speed
 
Your helix angle can be steeper then stock [ie 53 as compared to 47] and will allow your clutches to upshift faster and backshift slower or a shallower angle [ie 41 as compared to 47] which will give you a slower up shift and quicker backshift. This all has an effect at what rpm your engine runs at. You also can get a compound or progressive angle helix that starts at say 53 and ends at 47. The spring you use and the preload "wrap" of the seconadry springs have an effect on upshift and backshift in concert with the helix. This is all a massive over simplification of how these work and they must be matched to your primary clutch set up, engine power characteristics, riding style ect ect. Its not rocket science but there is a lot of testing and math involved in finding the proper balance of parts.

I would suggest you get a copy of Aaens clutch book as it will enlighten you to how all this works.
