What year/version of the Pol button do you run?

How does it perform?

Thanks,

I dont know if i missed reading it somewhere in here, but i was kinda curious as to how reliable a 1200 is? Was thinking of starting a build this summer and was just wondering, I have been following this thread for quite some time now so im just trying to get the basics for now, so i halfway know what i might be getting into... THANKS ALL!

I have a friend that built a 1050 in 98, its ten years old, two sets of pistons and 1 crank rebuild from launching to hard in an orchard testing for grass drags with 280 or so studs, so yes this sled isnt babied! just twisted the crank a few degrees. Has over 10K miles on it and has been through 3 diffrent chassis!!!!

If you run factory pistons and build the motor correct it will easily outlive a twin 800 since these motors fire every 120 vs 180, there is less strain, more balance and more reliability.

Same here, I have about 5 friends that have been running either Union Bay or Struther's watercraft motor for more than 7-8yrs. They take care of them in the off season, replace a set of pistons every 2-3 years and just ride the crap out of them in the winter, except for some minor things, not an issue.

Hallo RS, har hatt 4 (W/C)trippler de siste 5 åra å jeg er ikke i tvil om hva som er best........den gammeldagse knott variatoren til Polaris er den beste
Hehe,no ska amerikaneran få spekuler hardt på ka som står her

Ya, what woody said !!

 

[Snowstar]

So far this motor rocks! It can tear up a weak chassis though and rachet a track like no other. I have about 500 miles on mine and no motor issues.

Yeah I couldnt believe extroverts could ratchet even with a tight track!!!!

1 less HRP spider in this world left after today

goin with p85 now.

So, what is the most expensive part of the build?

So, what is the most expensive part of the build?

single part would be a new crank or new pipes. there each around 1100 bucks.......or a HRP WAS $1200......

if ya bought everything new....your lookin at around 6-7 G for the build.......If I remember right

you can budget build one for around 4 G tops

 

[mattymac]

I have about 6500 in my whole build! Start to finish including chassis!! biggest hit was the crank, been scavanging freebees for about 1 1/2-2 years though! It helps to know the right people!!

holz prox 144, coilover, 45" wide front with tripple rate works shocks, rolled CC, U-Cooler, MF lightwieght +2" hood custom painted, fly bars, scattered ti nuts and bolts, flexi skis, MM freedom axel kit, digi 4 window, 1200 ves, ultra ign, 13.5:1 compression, tcat rackslide carbs, CS pipes fitted by myself and a friend, and im sure im forgetting some stuff but no corners cut on this build!!

I own 3 poo button clutches, 2 are the later style with the belt deflection adjustment and one of the older style without the adjuster. My favorite button set up:
Deep and steep is 2.15:1 gearing, SLP MOUNTAIN 50/36 with Polaris gray spring in middle hole.
Spring time is 2.00:1 gearing, SLP MOUNTAIN 52/36 with same spring.
went through buttons rather quickly compared to a stock twin cyl. Always kept them with fresh large bushings in, changed them out when teflon started to wear off.

4Z: Thanks, making some notes here. Have Poo button, TEAM and a Bearcat machined to run "narrow" belts.

Be interesting to test them.

Jasså.... en 1050 ståanes si du??? Ka du tenkte ta for den?

Kjøre 85mm stempel i den , 1155cc, litt "magic-touch" fra Peter så...ja-ja..

E så dum med det her greian, kjøpe motor og greier i dyre dommer og klare f*** ikke få driten ihop å kjøre. Så går tida og man bynne sikle på nye ting..

Sug litt kan du si, men "that's racing" som dem si.

I figured most of the expense is in the crank. I can probably scrounge up enough parts and have my local shop rebuild it. There is no getting around the pipes, but most of this I can find for a reasonable price.

 

[mattymac]

I got about 550 in pipes with about 20 hours of labor.

Pol button gets my wote!

My TRAIL 1050 pulls 8400rpm (digatron) with this setup:

Pri: Polaris p-85 with 82gram weights and SLP 160-300 spring
Sec: Polaris button with r12(50-36) and Polaris grey spring (20-84)
second hardest setting.
Gear: 24-40 and 8 tooth(2.52) drivers.
Track is a 151x2 fingertrack with 500 kold kutters.
Chassie is customised 1996 aggressive, and I weigh 240 suited up.
This is at an altitude of 1000'

Go figure!!

Going to try a 50-42 helix tomorrow.

 

[Snowstar]

Holy crap ottar your swinging some weight. Whats your elevation?

I think I might have the balls to turn on the nitrous this weekend. I cant say enough how badass this motor is and then pure the laughing gas to it, lethal!!
