I know this a derail on O/T, but my main years riding were in the '70's, 80's and 90's. Remember the "thermos jug" front suspensions, and how Mike Knapp did a hell-of-a-job running his Yamaha's. Rupp

Journeyman, locks up here also. Using Chrome and Trend Micro. Haven't tried to troubleshoot. Doesn't happen all the time!

I should know this,but i'll ask, did all years have carbs?

Bought a 1983 SRV brand new, ran it until 1995. Maybe didn't realize it at the time, but the sled had great balance, front to back. Sit back on the seat and cruise, or, slide up and "get on the wheel" it would corner as good as a Polaris IFS. At least in my selective memory!! LOL. Being a...

Lots of interesting info, imo. edit: The "whys" behind some of the new stuff for 2016. snowmobiles.yamahablog.ca
