    TAPP Set up 998

    As the season ended, I started getting ready for next year. I am adding the 225/240/270 tune to my stock 998. Just did the intake clamps, 3bar, and BOV. Looking to put my TAPP clutch on it. I will be using the Ron Ward torsional secondary kit on the stock ADAPT secondary. Any advice on which...

    Got a kick out this video...

    There's a fix for that as well.

    2025 SRX photo leak?

    Your Doo dealer probably has crates of sleds piled up from the past two seasons like I see locally. I would expect the 2025 model year will be a bust for many dealers. Lack of snow, high interest rates, and lots of old product on floor plans is not a recipe for good snomo sales. Yamaha will sell...

    Tapp blowing belts compared to stock primary

    Thank you for the info. Ron Ward does his homework. The best I can figure messing around with my angle gauge is that the HT7 is about 3 - 4 degrees less that the stock helix.

    Tapp blowing belts compared to stock primary

    I used a Pro 4 with a TAPP on my 1100. They worked nice together. Getting a Yamaha secondary for my 998 may not be a bad idea. It would cost much less than a STM and there is a boatload of set up information on this site.

    Tapp blowing belts compared to stock primary

    Thanks for the info. I played with the ADAPT this year with the stock secondary. Next season I will use my TAPP and a Ron Ward set up on the secondary.

    Tapp blowing belts compared to stock primary

    Has anyone run a TAPP with the ADAPT secondary? I am curious to know the offset spec. Would it be the same as the Team secondary? Also, which spring seems to work best? Blue, Brown, or Black?

    Tapp blowing belts compared to stock primary

    I agree regarding the float. The spline on the shaft does not allow the secondary to move back under load. The old keyed round shaft allows it to float.

    ADAPT Verses TAPP

    The old 1100 Suzuki ( AKA Anvil ) motor was a pretty good industrial motor. It did need lots of boost to make big power. Unless cat makes a wider front clip for the catalyst chassis, I don't think we will see a triple in the current chassis. I was looking at a cross country 858 up close last...

    Riot 9000 / XTX 146

    I think model year 25 will be the last year for 146 EPS. Not sure we will see the pro cross chassis after 25.

    Highest Speeds on Sidewinder/Thundercat

    What really gets me are the people who bring apples to feed the deer. This trains them to hang around where sleds go. I view the deer as 150-pound rodents. We have all had near misses with wildlife. These stories remind us that the throttle is adjusted by thumb pressure.

    ADAPT Secondary Helix Angle

    Anyone have any ADAPT helix advice? Anyone test something less than the 58/49?

    ADAPT Verses TAPP

    Like my ADAPT so far, I put in Dalton weights and a billet cover after about 750 miles. Saw no wear issues but 750 miles is not a lot of miles. You can hear some belt squeal at low speed which may be noise from the bearing. Not sure on that front. The clutch is easy to work on and the bearing is...

    Highest Speeds on Sidewinder/Thundercat

    In NY 55 is the "absolute" limit but there is radar used on some trails. The trail system in Old Forge for example runs along some roads by residential areas so low speed enforcement and muffler decibels are more about noise than anything else especially near resident homes. Years ago, when...

    Highest Speeds on Sidewinder/Thundercat

    I view tracks as a wear item like tires. You do not want it to delaminate at high speed. Any sled I have with more than 200HP, the track is changed out at about 5 - 6 thousand miles just as a safe guard. If a track is studded, even on a low HP sled, I think 10,000 miles should be max mileage...

    Highest Speeds on Sidewinder/Thundercat

    That is a great build and big top end. Congratulations! Years ago I lost a studded track out the back at about 120mph on one of my old Tcats. I was fortunate there was a few miles of flat lake top in front of me to safely stop. Like speed ratings on tires, I have always wondered what is the...

    Sore Arms ……

    Proper handle bar height, EPS, and 8 inch dual carbides have worked well for me along with the viper spring in the front skid , lots of studs, and my shocks on the number 2 setting.

    1,000ft

    Thanks for sharing this video. I remember the first Mazda wankel engine I saw on the bench as a kid and have always had interest in alternate engine technology. I hope we see Mazda build this. I chuckled during the part where the narrator discussed how the engine might sound. I recall the first...

    sled weights

    You probably have 30 pounds of fuel and studs in that weight. It is probably around 565 lbs. with no studs or fuel. Thanks for sharing.

    Knockout kit

    I have not been bothered by the noise. A small earplug in my left ear eliminated the noise. LOL
