New, need help.

[Hanlon]

Hey guys, new to the forum, had this ski for a couple years, still don't know year it's this one almost 100% sure its a 1991.

Anyways, whenever I start going fast the front end starts bobbing up and down really rapidly, eventually the ski becomes uncontrollable.
I only weight about 130 LBS. Can anyone give me a cure for this problem?

to find out the year look at the last two numbers on the VIN/HIN tag on the right rear of the ski.


the bobbing up and down you are speaking of is known as porposing.

it can be helped with any or all of these: longer rideplate, shorter handlepole/steering, better intake grate, and most importantly rider input(which can only come from practice and more tray time)

good luck and welcome to the forums

Perfect answer.

Thanks motoman. I was thinking it was because I weigh so little, I'm getting pretty good.
How often do you guys do a rebuild.

 

[yankeeboy]

dont worry about a rebuild, some ski's can go years before even considering one. Just learn to ride, and if it breaks then worry about a rebuild.

Perfect, thanks guys.

it has 1990 graphics.

welcome, to the X! I have the same ski, find a 701 (because you have a 650) and do "the swap" but if not I have parts for your 650.

Whats wrong with the 650?

Whats wrong with the 650?

it's way too underpowered for the weight of that ski, without a lot of mods.

those graphic's were on some 91 sj's too.

there's some 650 yamaha superstock cly's out there that would wake that sn up.
fyi, a 701 upgrade would be easier to do.

good luck
