Ok I have a 2010 RTX and I want to put a 1.75" track on it and I have a couple questions
1) do or should Iuse 8 tooth drivers?
2) will the track fit without cutting of the heater exchange protectors?
3) if i have to use the 8 tooth drivers will i have to regear the sled? ( I am deleting the reverse from the machine so I assume I only need to change the top gear if I have to regear it)
THANKS!

Where do you plan to race because those changes will exclude you from any stock class per ISR rules

on the 2010 it will fit but i raced in the CSRA for the past 2 seasons on the nytro and they allowd me to run the 1.5" track in the stock class sport 600 and semi pro stock.

I have 1.75" track with original drivers, front protectors cut off.
But because of ratcheting going to install BRP 9 teeth.
For snocross I would change gearing for faster acceleration.
With 8 teeth you don´t have to cut anything(with 2.52 pitch).

So from what everyone is saying, You should go to 8 tooth drivers 2.52 pitch. That way the heat exchanger protectors can stay on, and it'll be like dropping 2 gears so you wouldnt have to gear it lower.
To get 8 tooth drivers I would call Avid, and get 8 tooth extroverts from them. https://www.avid-products.com/store/Pro ... ProdID=128

leave the gearing alone get the whal bros drivers and mess with clutching i had mine pretty dialed for holeshots usally was the first guy to the first corner in sport 600 and semi stock. biggest problem with snocrossin the nytro was the skid theres alot of welding to do to keep it together for a weekend. get yourself a set of fox evols they worked pretty good up front. no i wasnt the guy with the mbrp slip on i had to keep mine stock for the competive classes iam #909 not on yamaha anymore switched to cat

I'd go ahead and swap your track. If your club is like mine they follow ISR rules to meet insurance requirements for safety. The ISR technical aspect is a distant second. Besides, no one is going to care, you are racing a Yamaha and everyone already thinks you've got enough problems. 
Powerstroke,
My buddy just switched from Yamaha to Cat and I'm considering doing the same for next season. It is really amazing to see how much help he gets from a manufacturer that actually cares about racing. Plus the sno-pro is a heck of a nice chassis, it is way lighter and rides and handles far, far better than the Nytro. I never thought I'd consider going back to a two stroke but after checking out his 600 and hearing about how much better it is through the bumps, I don't see any reason not to switch.
Of course I wouldn't keep the sled past one season, and that would be a check mark against a two stroke, but since Cat has a race program, a guy can actually afford to buy a new sled every season and sell their old one. Who cares if the Nytro motor lasts forever? The chassis has not been changed and Yamaha doesn't offer the support that Cat and Polaris do. I like my Yamaha's for play and trail riding but XC racing is a completely different world and pretty much everyone (including Yamaha) has given up on the Nytro.
