    Riding with a passenger on skinz seat?

    Then don't start her snowmobile career by scaring her off...or do exactly that, depending on the outcome you want...! Seriously, two-up riding with the Skinz seat sounds like a very bad idea. There is going to be zero comfort, the rider is going to be squeezed against the handlebars and since...

    Riding with a passenger on skinz seat?

    I have the Skinz seat. Never tried to ride with a passenger (what the hell, I never even sit down myself...). I can't see it being possible as the seat is a lot shorter, narrower and stiffer than the stock seat. Only possibility would be if the rider is standing up as close as possible to the...

    Mountain riding with XTX

    Don't waste your time going powder riding with a Ripsaw track because you will hate it. The Ripsaw is a pure trail track that should only be used on mid to hard trails. It is good for saving hyfax in these conditions. Though, because of the cut apart lug design, it has got zero forward drive in...

    Skinz Air Frame

    If you have the MTX, this mod is needed. The stock running boards collect shitloads of snow, with these nothing.

    why can't america get these

    I was under the impression that extroverts and MTX tunnel heat exchanger is standard equipment in the XTX 1.75"...? At least in the Scandinavian spec...? And the TTX does not have the adjustable riser, this is only the X-Ride and M-Ride (limited edition models of MTX SE 153" and 162").

    why can't america get these

    The FX Nytro TTX is a limited edition of XTX 1.75" that is sold in Scandinavia only, simply because Yamaha Motor Scandinavia was not overly impressed with the performance of the XTX compared to some of the competition. The TTX is a XTX 1.75" where the dealer installs the TTX package during...

    Front heat exchanger protectors with 1.5" Intense track

    If you leave them in, the track will rub bad as you are exceeding the interference limit with some 3-4 mm. The tallest lug track that will not rub is the Cobra at 1.35". One option is to remove the W-shaped part of the Intense lug (the part that will rub the stud protectors). You can do this...

    Servicing Jackshaft/Speedo bearings, Questions/Concerns

    The re-greasing procedure has been described couple of times over and like somebody else already said - NO, this procedure is not described nor recommended in the Yamaha workhop manual. The re-greasing procedure does improve the life of the jackshaft bearing as well as the driveshaft bearing...

    Fastest Production Snowmobile

    Forget about the Apex or anything else introduced after the long travel suspension revolution. Even if they have got the engine, they are too high with too steep track to ground attack angle. I would say this is between the Mach Z and Thundercat, with the SRX as a dark horse. I know people...

    Steering...What years to avoid

    The A-arm ball joints used in the 2008 model were not that good. I seem to remember I managed to wear out three sets in one season of 4800 kilometers. They did an update to the 2009 model because my RTX SE is past 11000 kilomets and it has still got the original set with mimimum free play...

    AC skid conversion?

    Have a look in the Arctic Cat Float Suspension thread.

    The Arcitc Cat Float suspension thread

    Thank you OTM - quality information...! In order to complete the comparison, I will check my axle spacing in the tunnel as well as on the rails. I already know that my center swingarm mounting point is slightly lower and more forward than your calculated point for the "real" AC skid (likely...

    track rubbing tunnel

    There is enough room to run a 2.5" track, so the standard 2.25" track is for sure not rubbing from a lug height point of veiw. More likely from a side-to-side point of view. First, figure out exactly where the track is rubbing, then the correct countermeasure to get the track away from the...

    fox floats

    Remember that pressure is equivalent to preload on a normal coil spring. Because of this, set the pressure (or preload) to a number that makes the front suspension compress ~ 1/3 of the total stroke, which is ~ 40 mm front shock stroke, when you are sitting on the sled.

    Mountain riding with XTX

    If your XTX is box stock, a better track is first priority, lower final ratio is second priority and better skis is third priority. If you are going to use the same XTX also for trail riding, I would go for the Back Country 1.75" track. This option works also on the trail, at least on the...

    PRO RMK style snowflap

    Exacto-knife with a new and sharp blade - heated with a simple lighter - cuts the OEM snowflap like butter. The contours to cut are kind of already there.

    PRO RMK style snowflap

    As the Snopest gurus say - proper tunnel venting is the key to deep snow performance...And now I have got at least one part that is lighter than the equivalent part of the PRO RMK... Happy New Year to everybody...!

    2-stroke nytro mountain

    Yamaha Motor Europe got involved in building a buggy for the Paris Dakar rally. The buggy used the FX Nytro engine. Due to Yamahas fukked up spare parts system, where you can't get complete spare engines and for sure not assemble a spare engine at a lower cost than a new sled, they actually took...
