171 kph but........

[yamamarc]

Hey just went out for a good run! I did a wide open run 5 time and got the exact same speed and rpm!
My top speed was 171 kilometers per hour(speedo) and rpm's were at 9225 each time.
Should I be adding weight to weights?
I didn't hear the rev limiter what so ever but not sure if it's a tad high!
Btw this thing pulls hard more then I expected!!
I have the cotc with 4.5g in tips already and I think 2g in center!

sleds mod are cotc, airbox, sandales pipe and pc5 with hurricane map

this was the fastest the sled has ever went so far!!!! pretty impressed

171 km/h is 105 mph....that's pretty good. I personally feel this motor works best at 9000 rpm...but if you like it at that rpm leave it.

I am very happy with top end and don't expect anymore!
4.5 g in the tip is the max I can find with 8fp weights
If I did want to add weight it would have to be in center hole! Not sure how that would affect overall performance(I have 2g in center as is)
From what I noticed it hits 8700rpm then climbs from there

Leave it alone for god sakes. On the jack stand mine revs 9200 before hitting the limiter. On the snow the highest I've hit is 9100 and I've hit 161kph on a plowed road but only once. It consistently runs 150 but I'm 265 lbs.

Added 36 studs and went for a nice run!
Hooks up way better and the studs seem to have brought RPM'S down to 9166
Top speed 169km/hour

Man you it dialled pretty darn good, I'd love to see what you'd do with a Sidewinder

Haha thanks but I take no credit for anything this is all 100% TY influenced!!
It started with me and wife buying the exact same sled ( viper and zr 7000)
Then first season I was getting my #*$&@ handed to me and she would Bragg to all our friends.
I couldn't handle hearing about it anymore so that's where the great members at TY help me out with the mods...
Now I'm 3 sled length faster and just keep pulling away on top end...
That shut her up...lol
