 YAMAHA 700 Triple XTC-P

  • WE HAVE ADDED A REALLY NICE CONDITION VERY RARE MODEL OF 121 THAT WILL BE FUN!

  • ADJUST AND/OR REPLACE & REPAIR components THAT HAVE BEEN POORLY ADJUSTED OR JUST ABUSED.

  • END UP WITH A SLED THAT HAS  BEEN RESTORED TO OEM RELIABILITY AND EQUIPMENT.

This 700 triple is equipped with a nice 1.5" track. This sled's reasonably short track and all temperature responsive 115 HP mill make it a great trail breaker thru the tight NISBET FOREST trails.

         THIS SLED LOOKED IMMACULATE There were many items to correct and address before I am ready to put this sled "To the test"!

a) AS PURCHASED
b) OUCH!!
c) BULKHEAD REPAIR
d) AIR BOX INSTALL
e) FUEL LINE REPAIR
f) ROPE GUIDE ISSUE
g) REVERSE INSTALL
h) FRONT SHOCK CHANGE

 

 

  THIS SLED LOOKED IMMACULATE
Until I opened the hood!! Clearly in big trouble I listened to the seller describe the machine, word for word he was sincere and this meeting exactly matched our conversation on the phone! When I showed the Dude a major problem he just about _ _ _ _  his pants!

a) AS PURCHASED
This special edition 1998 Yamaha XTC-P, is and was absolutely immaculate to look at.

Yamaha failed to build (at the time) sleds with wide stable front ends and 136" or 141" models with 1.5" tracks,
    
that would be suitable for the large "cross-over" market made popular by other manufacturers  in other regions of North America. It was either a narrow ski-stance Mountain sled or a 2-Up touring equipped with a basic 136 Inch track topped off with a couch.  

This small snap and write up in the Canadian 1998 Yamaha Sales Brochure is the only mention of one of the best equipped Red Head "700 121's" ever built for the Saskatchewan prairies. Absolutely the 1.5" track provides ski lifting traction in the Nisbet hills and blown in trails, limited by your aggression! The track and  1ST time offered, USI plastic skis round this hot rod off nicely. We add dually style carbides for road crossings and bladed logging roads in the forest.
Mountain Max models gave up their dish pans and also received these skis for the first time in '98.

 

 

 

 

b) OUCH!!

Unfortunately we discovered that when you raise the hood we found some serious collision damage. With a straight edge in place you can see the
 

bent bulkhead and the area where the clutch would make contact
.

This notch was cut into the bulkhead where it was buckled because as...
 

...the sled gains speed and the secondary clutch opens it would make contact.

 I have disassembled the sled and installed a port-a-power over the engine pushing the front back out.
 Pushing the front back out I am able to straighten and rebolt in braces and also rivet in a brace to keep the bulkhead straight. The red arrow is pointing at the notch cut in the bent chassis by the secondary when it would open at speed.


Here the bulkhead seems to be straight again!
 

The front frame damage from "in my experience" would be a horrendous leap or jump into a ravine or such creating an impact like this. I had seen damage like this once years ago. The trailing arms and radius rods and shocks were all bent on impact.

c) BULKHEAD REPAIR

 The brace over behind

the primary clutch.

 The brace as installed behind the secondary

but not trimmed back for clearance.

 The brace as installed.
I take an "unsophisticated"  but effective approach to trimming the reinforcement back to OEM clearance.
 


I trim the aluminum angle back...the bulk head stays straight!

 

 

d) AIR BOX INSTALL

This is an issue I have seen many times, by attempting to install the air box as a whole, which is possible...a carb boot gets inverted and folded backwards.

The consequence is she could suck outside warm under hood air lessening the engines potential, but another issue could be sucking in snow in severe conditions.

By disassembling the air box you can  see directly that the carb to air box boots are in place, and you can check the air box for debris.

You can physically see that the fit is secure.

e) FUEL LINE REPAIR

It appears a shop has gone thru a lot of trouble to remove the OEM fuel lines...

...and install aftermarket fuel lines and screw clamps.

This hand full of junk is going into shop recycling...

...screw clamps have a place just not here.

 

This hand full of junk is going into shop recycling...

...OEM spring clamps that expand and contract with temperature are better suited to these lines and the coolant hoses.

Ordered from our local Yamaha dealer...

...and now installed. I know I got the good stuff.

 

f) ROPE GUIDE ISSUE

Some one must have been in here to do some chaincase maintenance...

...they are pretty maintenance free so with the low KM's on the sled I could only guess a monkey was in here looking for work. 
Who ever it was, it looks like it was some time ago by the way the rope had sawed its way into that chain case cover casting.
 

 

From the side it doesn't look like anything is wrong.
 


Once the chain case is back together I am sure to install the rope in the guide.

g) REVERSE INSTALL

This is the spotlessly clean image of

...the original sprocket and chain.

 

 This is the OEM upper sprocket and chain and it's excessive slack...

 ...there is more slack than the complete OEM application because the "reverse gear" lower sprocket is smaller than the original.

 Here the upper and lower sprocket spacer bushings and the reverse idler shaft is installed.

This chaincase is as clean as a whistle.

As a result a smaller upper sprocket and new matching chain is installed to take the excessive slack out and...

...to give the chain case many years of new life!

 

 

 

 

h) FRONT SHOCK CHANGE

 The front shocks OEM are very high quality KYB models

At a glance they looked perfect. But bouncing the front bumper the sled, she just bounced like a
"
BENNETT BUGGY"

 Here the upper and lower sprocket spacer bushings and the reverse idler shaft is installed. Clearly when the front end took such a hit to bow out the  upper bulkhead

...I would imagine all the gas/oil was blown out of the front shock absorbers.

 

 

 

 

 This is no obvious evidence of damage or leaking oil...
 ...don't think there is a drop of oil in them!

Like I said they looked good...

...just had to be changed!
