1998 V-Max 700 SX

I just purchased a 98 SX 700 a few days ago, I have put 150 miles on it already and it goes great. The motor was rebuilt last season, it has triple pipes, and cranks right along. I raced a 2004 f7 yesterday and we were even until 70 or so and I walked right away. I have been looking for more information on the specs, like stock power, weight, track size, what kind of handwarmers it takes (the only broken thing on it). The rider of the F7 had a 30-40lb advantage (scrawny little guy) a brand new track with 144 studs. We were on hard packed snow. My track is worn a bit with 144 studs and the guy said he lost because he couldn't hook up but his track is better than mine and it wasn't like I was hooked right up. I also had it at an indicated 100mph with my wife on it with me in powder. I have read a lot of trash talk on the 700 SX online but my experience is counter to that. It goes great, is comfortable, and sure isn't a slouch.

Thanks, I just wish I knew more about the sled. I can't even find what the stock horsepower of one is. Maybe I just suck at google haha. But I figure the triple pipes are +~25hp from stock judging from what I got from the various retail websites for the different brands of pipes.

I did some searches and also basically came up blank. I don't know on the pipes either. AAEN and Bender are two of the bigger names that come to mind but I really don't have a clue if that is what you have.

judging by the stingers, they look alot like hauks howlers. bender and aaen usually stamp there name on the pipe. stock hp would be in the 120 range, and your not far off with the 25+ increase. dry weight per yamaha was 500 lbs track was a 15x121 with a .92 lug heigth, or might have been a .75. right at the borderline year for the lug heigth change.

Alright cool, what did they change from 97 to 98 regarding the belts? I wasn't too sure about it being a MY98, it was made in 5/97 so I didn't get the belt because they are different between 97 and 98. I don't have a title for it or anything and I can't find any info on the sled anywhere regarding belt type but the mfg date is 5/97 so that should be model year 98 right?

srx and sx are 2 totally different sleds requiring different pipes. and there was no improvement to be gained, except weight over the stock SRX pipes.

right side of tunnel, by the footboards is the vin. get the first three digits, i will give you the year. you may want to consider making a few changes to the clutching to run the upgrade 8DN belt.

I don't know too much about all this stuff. I looked into the 8dn belt and I read that it was too stiff I think and was prone to slippage. I just bought a replacement belt in anticipation of winter and I purchased just the regular old Gates Xtreme belt off amazon for 45 bucks shipped.

I actually was just out in the garage sitting on my sled dreaming about snowflakes. I need to replace my handwarmers and I should be all set for now.

if your sled has aftermarket pipes, chances are the clutch work is done, especially if its currently running the 8DN belt. slp was very good at giving set-up info. you should be good to go. have you ridden this sled yet?

that gates belt you just purchased will probably create a little heartburn for you when install it and try to run it. before the season gets to far along and you need to depend on that belt, try it out. it has a considerably softer compound and is slightly longer. assuming your clutches were set for the 8DN, the gates will sit lower in the secondary, actually acting like starting out in your truck with second or third gear, and the primary will grab it quicker causing an over-rev, before the secondary can catch up and shift. and the gates really like to grenade themselves. been there, done that. personally, i hate the gates belts. your sled is happiest with either the 8CH belt or the 8DN, when all components are correctly tuned.

The belt that was on it when I bought it was the same thing. I figure if that was what the previous owner was running with it I would be alright. I know that I have the brand new one as a spare right now because the one on it is being a bitch to take off. What needs to be done to set it up for an 8DN belt? I was told by the previous owner that it was tuned/clutched/jetted etc to run the best it could because he raced it. Outside of that I am clueless though.

I haven't gotten to ride it except up thru my backyard in wet grass. The clutch grabs bout 4 grand and it takes off... Im so pumped to ride, i had a oil light problem but put new sensor in tank and it took care of my problem. I Still have to get plugs and extra belt and im ready. I believe i have stock reeds but it had a fuel tube on the intake side of carbs, im not sure what all it does?

if the belt is that bad to remove as you say, you need to learn the tricks for belt changing. as for setting up for the 8dn, its a basic rivet change in the clutch weights, a different wrap on the secondary, maybe a spring change on the primary, and shimming the secondary for proper belt ride height. i understand this may all be greek to you, but guidance and knowledge is readily available on this site, from me, or others. ask, try, learn.
