need more rpms

[SharkAttak]

try it in b1, i believe stock is a1, that should be alittle stiffer

MAybe I should start another thread all about this...

BUT.

I did the upgrade from YXR to YVX secondary clutch in my old Exciter... I bet I could use all the same parts and throw the YVX secondary in my ne Phazer... I used a secondary from a 96 Vmax 600, I'm sure the whole setup would go right into my Phazer.

Wierd that Yamaha went back to the old style clutch on this sled.

Changing the spring position does that just affect the engagement? or what else? I'm curious, clutches are still a bit mysterious to me...

Here's a dumb question: How do i spread the sheaves so the belt will come off?

 

[Mars]

Turn it a bit, and push the inner sheave inwards (towards the tunne), then with your other hand jam the belt deep into the sheaves, and pry her out. I can do a belt in 15 seconds.

Here is a tidbit of info about clutching, from the tech pages :

Thanks for the help Mars. I've got a pretty good handle on cltuching, I did all the clutch work on my Cat 900 myself. I've just never dealt with Yamaha's before.

 

[Mars]

That was for Phazed-Coug...

Look up ...

Wasn't trying to insult your intelligence, I was helping that guy out. haha.

 

[RockinJW]

Oh, no problem...I've got the secondary off and sitting in y lap right here. I can see the numbers on the backside, it's in position one. Where are the letters at?

Can I move the spring to the number 2 position? I just don't see the letter B anywhere?

 

[Mars]

Letters should be in the helix... Under the spring, you'll see when you take it apart...

Helps to have and extra set of hands before you undo that circlip... or a clutch tool obviously.

 

[RockinJW]

I got it apart now. It was in B1 so should I go to C2?

 

[Mars]

add another 20*, whatever that comes up to...

See what happens.

DOn't forget to post your results...

I have a supertrapp superlight stainless slip on coming in the mail, and wana know what to expect.

 

[RockinJW]

I only went 10*. I'd rather make little steps to get where I need. That way I know how much each change affects it. Also, I'd rather still be under peak rpm then over-revving all day.

I've talked to a few companies and nobodies really making clutch kits for the mtn lights yet, so I might just start tinkiering on it myself. I've never owned a sled that didn't get major improvements with minor clutching.

My Cat worked awesome with a multi-angle helix, so I might try something like that...

I'm going riding in the morning, so I'll let you know...

 

[Srxspec]

Rev limiter is 12,200 rpm.

 

[Mars]

Holay nice HP/tq curve... shouldn't be too hard to clutch that. 2100 RPM span that makes about the same power.

 

[RockinJW]

Well, I just got back. Tightening the spring up brought my r's up on the trail but the second I got out in the powder and put a load on the sled it would drop right down to around 10,500.

Plus it made the engagement and wide-up different. The sled would hit about 8800 and then fell like it just hit a wall. It would hover at 88-8900 for a few seconds then jump right up to 10600 or so.

I'm gonna move it back to where it was i think.
