Exciter II SX ( 1993 )

get those sxr shocks resprung and revalved from maxximum performance, you wont be dissapointed.... had mine redone on sxr for the wife worked so good, i sent in my viper shocks the following year.....

kinda pricey, but an awesome mod.... will improve the ride so much you wont miss that exciter anymore..... my wife came off the ex 2 sx for the sxr and she would never go back... now she rides a vector... even better yet...

No kidding, I have 155 mains in my SX right now, and was going to put in bigger ones cause I have just added a PSI single pipe.. My pilot is also a 55.

Are you near sea level? Did you ride cold temps?
 
Lasse, if you have the original primary clutch I suggest taking it off for either the 1995 or newer YXR or put a Comet or Polaris primary. That original clutch had the white plastic slide towers that had problems with binding. You'll never achieve top performance with it. I had the same sled with a Bender pipe from 1993 until I bought my 1997 600SX. I ran a Comet 108C on it.(new YXR wasn't out in '93)On the COmet or Polaris clutch you will need a tall red Polaris spring which is not the one they list. Not sure if they make it anymore. Otherwise the Comet blue part #202552 works just as good. For weight arms you can use Comet A-52 (about 52 grams) or Polaris #10 also 52 grams ...either work fine. In the secondary clutch run the stock spring and cam at around 50-60 deg. twist. Also use the 87X Yamaha belt. I guarentee this works awesome. I ran this setup for 4 years and at the time that sled was very hard to beat in my area. It gave much larger sleds of that era fits.
 
check to see if it had the updated cylinder's, they work alot better (more performance). Also get a "45-39" helix from a VK 540, have it machined were it rest against the snapring the same as the stock SX helix, and hold on tight!
 
Alright, I went to a local snowmobile used parts place, looking for a clutch... Will any year Polaro clutch fit my Exciter SX, or do I have to find a specific one?

I need rollers, and stuff in mine, and I would be better off just getting a brand new one.

I had a 1987 Exciter (First Year). Upgraded it with Fox Shocks in the rear skid, & did some clutching (lots of HP available here). I loved the sled and even though it only had about 5 inches of travel in the rear, it rode very well. Had to rebuild the motor at 11,000 Km. Once had a guy on the trails get off of his Pooolaris XC800 and say "I can't believe your still on my tail???".

The Exciter weas excellent on fuel and injector oil. Bullet proof motor. Just make sure you coolant lines aren't rubbing on the recoil or other moter parts. There was a tendancy for them to wear through which you don't want.

Sold mine three weeks ago after buying 2001 SXR600 late in the season last year. Now I'm trying to get the SXR to ride as well as the old Exciter!!! The SXR has more travel but the shock valving negates much of it.

I in mourning still!! :>(

You made a good choice.

Here in SWEDEN many are talking about replace the Driven/Secondary clutch to a newer one from a 1995 --> or newer Yamaha.

What are you guys thinking of that ?

How do I see if I have the updated cylinders ??

To bad you couldn't get the 45-39 helix to work. My SX worked flawlessly on tight trails and on the lake. That trick came from Tim Bender himself.
 
We ran 42/38's in them that was about all it would stand and still back shift, the Yamaha 45-39 sucks its got a step in the middle, that was the best of the exciters, my last sx I put a 600 twin in it with PSI exciter twins, WHAT A GAS, and yes Ohlin made struts but I never had ones for the sx because the tops were different for the adjuster, I doubt if the single pipe will help, keep in mind it needs to run 7800 not 75 or 6 like a stock ex, the sx has higher ports and a shorter Y pipe so it spins a little higher.

They came with 155's but you could run all day with 150's. So just take it and lean it out, throw a 42-38 pink spring A-2 in the back and a couple shims in the front, take it out and give it a poundin'

Explain moore about the step in the middle that the 45-39 helix has

Yes I know of the port timing and so but does it really have a shorter Y-pipe ?

Let's see now...
* Pink 42-38 Primary clutch spring
* A2 in the secondary clutch

Explain moore what you mean by couple of shims in the front


THANX everybody for the help so far :rocks: :WayCool:
 
The original stock 45-39 8K4 (81SRX) helix was not a progressive angle, 2 straight angles with a step in the middle where they meet. So we had progressive angle helixes made to get rid of the step and give you a smoother transition, better backshift. Your sled came with a straight 39.

The secondary gets the heliix change with the pink spring wrapped at A-2

The primary you can use the stock spring and just throw a couple of Yamaha engagement shims in it.

Yes the exhaust is shorter on the SX to match the port timing change, thats why the SX's ran 7800 rather than 7300.
 
Yep the step made the helix hang up a bit. Believe me with the setup I gave above, you need no multi angle helix. As for a Polaris clutch. The P-85 will work. You can adjust the washers on the secondary for alignment. Lasse, yes the 1995 or newer YXR would be great and longer durability. I just don't know the setup. It would be worth a try though.
