nytro turbo gearing

[jehay]

thinking of gearing my nytro turbo up to 21 tooth one tooth from stock. Has anybody tryed this and how did it work out for you. I have tons of power out of the hole and bottom end power i thought that gearing up i might get some more track speed in the deep and steep!? Turbo is a powder lites stage 2 at 14 psi 280hp. Any thoughts!! Thanks

gearing

i like it geared down to a 19 top better than stock it had more track speed geared down even on boost, belt ran cooler and was more user friendly it tighter situations. imo thanks

I geared down to 19 on top too, still getting 80+ track speed climbing I like it much better.

Me too!! would never think of gearing it up.

dont mean to steal the thread but whats involved in gearing up/down ? do you need to change youre chain or any thing eles out other than the top gear ?

I have the non reverse model and I just changed the top gear from a stock 20 to a 19 and the chain works fine.

 

[rednytro]

does any one know what part # to ask for to get a 19 tooth sporket i just called 6 yami dealer ships and they said a 19 tooth sproket was after market ?? do the 19 tooth come stock on an rtx or another model by chance ?

my 19 tooth came in a yammie bag....tell your dealer to open his book and look a little harder.

I agree, down is the way to go. much cooler belt.

I'm at an 18 on top. It is not my thing but, I was ripping it across a lake and hit 93 on the odo. Thats with a 162 on it.

The stock tensioner works fine with an 18, so a 19 should be no problemo

I put a 19 tooth on a reverse equiped nytro. Still using same chain. I have a manual at home and will post the part # tonight when I get home for the 19 tooth gear. Any Yami dealer who says they dont have a 19 in the book is a moron!!!

you can get them through yamaha or wps, western power sports.

BET THAT THING HAS SOME SERIOUS BOTTOM END TORQUE WITH AN 18

it will do back flips

I would be careful running an 18 with boost, there is not much metal left, could easily gernade the gear, I have seen it on less hp. sleds.

gear

the apex uses the same top gear as the nytro if your dealer cant find one for a nytro.

Confused

Hi Guy's,

Been following this thread and it has me confused. I would have guessed gearing up with the turbo, to achieve higher track speeds? Does the belt overheat when you gear them up? I am running a powder lites stage 1 @ 9-10 psi with a climbing track speed of between 85-100km/hr depending on snow. I was going to try gear it up because my buddies with turbo RX-1's and Apex's are getting 120-130km/hr track speeds in the same snow. What are others getting for track speeds @ 10-12 psi on the Nytro's?

I'm running
8bU' loaded right up in both holes
Shockwave straight helix
14.5mm rollers
Arctic cat Blue wound to 70 degrees

Thanks Sean

Part # for a 19 tooth gear is 8FA-17682-90. This is the Yami #. Take this # to those dealers and show them who knows more

I have the powder lites stage 2 big time more power then the stage one not even close do the up date it is worth it trust me. With the new bike box it is the sh-t. Track speed went from 90km to 120km with the stage two and alot more bottom end 286 hp and 230 on a stage one. 56 more hp
