    Most miles in one day?

    I did 320 miles on a 1994 v-max 4 when I was a lot younger. I was shot after that ride. Have done 300 on my apex and a lot easier but still can kick your #*$&@ especially if last 50 miles are 2 footers like they usually are!!

    Love my power steering apex

    I just thought I would comment on my experience of sleds over past years and how happy I am on my apex compared to a lot of new chassis that everyone thinks they need. I have bought NEW yamahas every 2 to 4 years since 1995. Only one time did I needed warrenty work and that was on my 1998 srx700...

    slydog ski scrub top speed?

    I did do some testing swapping skies and the Slydogs did NOT effect top speed. Did a lot of suspension changes and was affecting top speed more. Thanks for feed back.

    144 or 128 apex.

    I bought a used 2013 xtx last night. It has bar risers curve skies and studs with only 1k miles. Took it for a ride and don't know if skid has been revalved but rode really nice even in small studders bumps. I did not know mcx was a rear mount turbo. I will be looking into that in future! Thanks...

    144 or 128 apex.

    Riceburner, Do you trail ride with mcx turbo? My last turbo apex was a front mount powder lite back in 2006 and had a lot of heat issues. I am looking at supercharger next or rear mount turbo??

    144 or 128 apex.

    Considering buying a new power steering apex. I have not rode the xtx and worried that I will loose some top speed and also ride compared to mono shock 128? Some say the xtx is faster but is this in short distance? Make no sense that 144 should out run a 128 in 1/4 mile race? Also hear the duel...

    Oh well may have to buy a doo if they release a mach z 4 stoke. I will not by another 2 stroke. I am sick of changing pistons and cylinders! And that is every brand 2 stroke if you run them hard. If not apex still is a great sled that is hard to beat on a groomed trail. Speaking of that I put on...

    Slower than my Nytro

    I fond on new cats if you pull up front limiter strap will see some gains. Does steer little harder but this was on a big heavy turbo sled so should be better on viper. Nos pro. Have you found that you have to squeeze the belt harder on viper compared to nitro? On cat clutches they are running a...

    Slower than my Nytro

    I knew the nitro would be faster. Its a Yamaha! The one really good thing about Yamaha sleds is efficiency. But from what I hear cat is a better handling and bump sled. Can not have it all.

    Limiter strap setting on 06 GT with snotrackers

    Believe it or not skies will also help. Try a set of Yamaha tuner skies. Steering effort is light and put longer carbide to inside of ski. Then when u get ski lift the ski will give a little with shorter less aggressive outside carbide. They my push a little but I ran more front spring pressure...

    Anyone know the weight of mono shock compared to new cat skids? Also I bet the apex motor is close in weight to the turbo generator motor cat has. LOL!

    Eichenberg Racing has the pole at the Soo I-500

    I would think yammy motor with exhaust and air intake mods with some good fuel mapping would run with any modded 2 stroke that has to run hard for 500 miles! Should be close to 150hp and run reliable!

    Eichenberg Racing has the pole at the Soo I-500

    I just read the rules quickly and aftermarket heads are allowed. Sure valve train is open then also. Better luck next year!

    Eichenberg Racing has the pole at the Soo I-500

    Wow dropped a valve. That is not common but sure could have been lean fuel mapping or aftermarket cams/valves if that is allowed? Does anyone know what happened to other yammys and or 7000 cats in race? Congratulations to Bunke racing for top 2 spots! Polaris has some bragging rights after...

    Well I am going to order new sled for next year and would be very happy if they just updated apex with lighter or more powerful motor! I personally would prefer that over a catpex!! Only other sled that would get my interest would be a 4 stoke mach Z????

    Fogging glasses

    The no fog mask worked for me. Still have to be careful not to breath really heavy with shield down. Its fairly cheap to try.
