Phazer MTX Set-Up for Sea Level

LJ 452 · Sep 5, 2007

I'm considering a MTX for the wife and in discussions with the salesmen he asked if I would be using it below 7,000 feet. Living in MI you know the answer. Anyway my question is has anyone else at or near sea level had to make clutch or remaping of the fuel curves, etc. If so what did you have to do.

Any input greatly appreciated.

I think somebody, maybe yamaha had flat lander specs for the phazer..... search for it, i think there were some posts about it last season.

Look up European specs. All mtn's are delivered to Europe with sea level specs.

SEA LEVEL

YAMAHA SUPPLIES THE KIT N/C , CALL YOUR DEALER

It is a gear change for the sea level sleds. Easy fix.

I live in Munising in the UP and the dealer put the 3,000 ft elevation kit in and in a week I took it out. Heres why, I noticed 1000 RPM drop through the throttle from the kit which wasn't bad and the mid range was improved. Top end only changed from 79 Mph to 80 Mph, only gained 1/2 mile per gallon from 12.5 to 13.

The biggest reason for taking the 19 tooth gear and lightening up the clutch weights was the clutch ran way more effecient and the bottom to mid range came back. I ride strictly bush and climb hills in deep powder and the quick acceleration is needed. If you don't do this kind of riding the elevation kit will be fine.

Ok I guess I have two remaining questions.

1.) What exactly comes in the kit. Gear, Spring, Weights, rivets?

2.) Does your dealer have to intall this kit? Mine says they can get it but it will be $100.00 to install. They claim they have to exchange whatever they install. :drink:

I suppose this is possible but it seems more of a way to make some money off of the deal. :o|

You would think 7+ grand would be enough in this economy but I guess not.

Hey,

I have a short track phazer that I am long tracking and will need the elevation kit. I already ordered my gear change and clutch parts, BUT, I would be willing to sell you the gear for your change. I would say 1/2 the prce of new. It has 500 miles on it.

Let me know. The cluctch parts are different weights and rivets. I would be willing to sell you the weights and rivets out of mine also. Same deal, half price of new.

Thanks,

Steve Burdick

Ditto That ! :Rockon:

...Unless you're gonna be running at high speeds a lot , I'd leave it geared for the mountains , it'll probably be a lot quicker from 0-80

LJ 452 · Oct 18, 2007

Yeah, the gearing I'm not concerned with as much as the weights. If I can get better shifting with the sea level weights than I may want them. If it's not going to make a big difference than I'll just add weight to the stock weights. The main thing is that if I'm entitled to a free kit at no charge and no exchange than I want it. If nothing else just to have the parts for tuning trials. If you have to return your stock setup to Yamaha than as I said I just purchase what I need.

Thanks for the replys and offers I may buy the weights. Any idea what they are new? Isn't it around $150.00 for all three?

i have weights "left" over from Turbo install, OEM.

my machine is 19/41 geared 8tooth drive whels

Sorry my bad english :o|

asrx600guy · Oct 28, 2007

I'd buy some aftermarket weights before spending $100 on what should be done as part of the dealer setup. who is the dealer?

Yellowknife · Nov 15, 2007

My 07 Mountain Lite is still stock, and it ran great last year with the exception of hitting the rev limiter while going full throttle on hard packed snow, which I rarely do anyway...I ordered the kit but don't know if I'll use it. I love the way it handles/accelerates now

JohnnyHollywood · Jan 11, 2008

I bought the 19 tooth gear and 13.9mm rivets for the weights. Now there are two holes in the weights. Do I drill out the old rivet or press it into the second hole? You would want to lighten the weights wouldn't you?

LJ 452 · Jan 11, 2008

According to the Yamaha setup sheet you want a steel 13.9 rivet in both holes to adjust for Sea level. Attached is the sheet. So you must drill out the other rivet and place the 13.9 (part number 90261-06034-00) in both of the holes. You will need a total of 6 rivets to do the clutch. When I change them out I use a bit that is larger than the hole size as all you need to do is get through the flat faced side and you can tap the rest out. It's very simple once you've done it a few times. Remember to do one weight at a time. It may not matter much but I always figure they ware in differently and should alway be returned to the same location. With this settup running everything else stock on premium fuel I've pulled 11,000 to 11,200 RPM WFO and 70 - 80 depending on conditions. Pretty good really considering I tip the scales at 250 lbs. With that there seems to be a lot of belt dust in the side pannel. MAybe normal for the Phaze but I think this summer some clutch work is going to be done. Ie. lighten up the primary and try a roller on the secondary. Mmmmmm
