I've gone from a 1.95 drive ratio to 2.05

with a green 160/300 secondary spring and knocking my ramps down it feels good.
Doesn't stop pulling steady right at 8K with quicker acceleration and still a good backshift. Actually it feels like I have some "engine braking" effect off throttle which will make me smoother through the corners at higher speeds not having to use as much brake...
another effect of these changes is spending more higher speed running up in the OD dia. of the TRA.
This equates to as good or better high speed MPG and no top speed loss. It might even be a couple ticks faster because of the OD effect.
Gotta mark the clutches with a sharpie to know how far the belt is coming up in the primary at WOT

no rocket science here. Ski-Doos are typically undergeared from the factory and will pull more ratio. 'Ya just gotta "unlock" the additional performance that lurks.

I've run a similar program before many moons (9-10 years ago?) with my Mach Z. Pulled harder and picked up 5 on radar in trail trim from 106-111, with little other tuning. Of course there was 150+ 2 stroke triple HP to work with. where there's only 108 HP here.

Just talked to Jeff about that. I'll be working Thursday. Off the following week though.

Rode pretty much all weekend. The sleigh needs traction. No studs and the stock 1" track are no match for that engine. Still trying to decide on new 1-1/4" or studs on my 1". X-mass shopping is not done yet so I'll probably do whatever to it after X-mass. Sled is whicked sketchy with the lack of traction. Gotta go easy for now. Once it hooks on something though, it really gits it. Need to crank my suspension up just a bit, this weekend gave me a good shake down to get used to it.

After being out of the sled program for four years, I'm a little apprehensive about hoggin corners at or near full-on. Just seems a bit bizzare, didn't used to to, but it does now. Maybe just need to shake out the cob webs,,,,,,,,,,,,,, or maybe I'm just too old!!!!

Randy,

Your mods look great ..... now the question is can you ride ?
I like the 353 .... nice touch ..... just think if Pete were to have put something on the side of his sled it would say "Lightning McQueen" (from movie Cars) ....

Just kidd'in about the ride'in part ..... looking forward to Thursday ....

Talk to you soon ....

Jeff

P.S. Oh yeah, about the Goldwing Nissan Sentra deal you were refering to ..... I think you meant to say something like "that sled is a combination of a Hybusa (fastest production bike) with the luxuries of a Lexus ....."

'Bird, the new Camoplast Cobra is the ticket. Rave reviews over and above the Ripsaw.

I am running the stock 1" also. Not so bad at this power level. I've always been a shorter lug/aggresively studded kind of guy. Makes me prefer harder conditions for obvious reasons...

If I was to make a change...COBRA.

as far as cobwebs...they'll clear. I was a force last year in no time after 3 years off. Just gotta ramp up to it, but it's like riding a bike.

Goose Bay last March.

You can hear Norm Horner who with a couple other A-bay locals took this to the next level back in the mid 90's.

We used to trail ride over there on a Sat. make a few trail trim passes and enjoy the scene...

The "holy chit" comment by Norm is about the dance to the right of the lane up-course when the boost starts coming on strong...
if you watch closely in the slow-mo's you can see Parker's still carrying the left ski thru the traps.

I heard he was into the 180's a couple weeks later.

my gig was bracket racing on Henderson Harbor ice. That was a great buch of guys I used to ride, race, and party with back then, back when Louie owned the Westview.
I was quite successful with my '95 Mach 1. In the weeds, slide lube pump, 300 steel ice picks, the whole bit.
There are trophies collecting dust in a closet here somewhere. It was set up well and was very consistent. Seldom broke out and would often subsequent rounds just hundredths over my dial-in.
My scanner is kaput or I'd post some good pics from those days...

and wieghs in like a school bus.

then what's the 900 for?

plenty of 370 fans out there for sale...

I've seen him ride...

I think just "Queen" would do.

Straightaways!!!!

Thursday looks like a washout...

literally.
