Hi guys! Been searching around for a while for the correct installation procedure for the old style collar in the jackshaft bearing behind the secondary. This is on a 2003 RX-1 Mountain. I am doing a complete driveshaft / jackshaft bearing change and I need to get this together tomorrow. The...

Hi! Since I got my winder I`ve had to empty the intercooler two times for engine oil due to not being fast enough with pulling the tether cord when lying upside down. My dealer says that I can just run the hose into free air (guess a little catch thank would be smart) and disconnect it from...

Hi guys! Working on a friends Nytro that seems to run way to rich. The tunnel behind the silencer is all black from smoke. Two years ago I replaced the MCX box due to failure of the old one (startet bogging when trying to build boost), and the sled ran flawless. Next season it started to act up...

Hi ! Has anyone added more coolers / cooling system to an MTX ? This weekend I got the rews limited due to overheating, happened when I stopped the sled and let it idle a little while whilst deciding what line to pick. Snow was hard packed just before I stopped and I didn't have the ice...

Hi guys! On Sunday I sidehilled my Sidewinder MTX 162" and eventually when it got really steep I got stuck. Easiest was to roll the sled down, so it rolled 3-4 times. I let it rest a minute and then tried starting it. The front of the sled was pointing down the hill, it`s wasn't that steep...

Hi guys! Friday I picked up my 2018 (brand new leftover) Sidewinder MTX 162 LE. When I got home I installed the MCX race muffler, MCX out of the hood air intake, tether switch (oem), green arctic cat primary spring, drilled out the oem "rivets" in the weights and installed some "rivets" that I...

Hi guys! Been quite a while since my last post on the forum, many many years actually. I left you when the Viper came. Been riding my good old Nytro 162" MCX 190 Skinz since, still runs like a champ after 9000km. That being said, I have a feeling the Sidewinder is a good quality sled and...

Hi guys! A friend of mine just bought a 2011 Nytro XTX MCX 240, sled runs great and everything seems fine, but if you let the sled sit for 15-20 minutes and then fire it back up and take it for a rip, it bogs heavily when trying to build boost. It backfires and sputters really bad, but if you...

Hi! A friend of me just purchased a 2011 Nytro XTX (MCX 240 + lots of skin stuff) and the track needs to be replaced. It as 9 tooth Avid drivers and a 2" finger track for the moment. What is the max lug height you can run with these drivers? :4STroke:

Hi guys! Just purchased and installed my 39" Skinz Concept front end, now I`m looking for some suspension setup tips. I haven't been able to ride sled due to lack of snow and when the snow comes I want to ride as much as possible and not fiddle around with suspension adjustment all the...

Well as a good old member and a loyal Yamaha man I still have to say that I am still speechless.. . Until recently I hadn't realized how stupid and idiotic the values in my life were. Cause, this new Arctic Cat deal is killing me. Well thanks for the wakeup Yamaha, I will try to...

Hi guys! Here is a fast edit from last weekend, just got a Gopro camera so I had to test it out:) http://www.youtube.com/watch?v=iq3fSnlg ... re=mh_lolz Kimoaj

Hi guys! Yesterday I got my Grimmspeed manual boost controller and it looks awesome. I really look forward to trying this out. However, I did ask Erik Marklund what his thoughts were and he said that he couldnt see any benefits of installing a manual boost controller cause the TCV should...

Hi guys! I am joining the manual boost controller club and I therefor wonder what AFR I can run on my Nytro. I guess the 180kit needs to run richer then the 240? Everybody sais that it can handle 190-200hp and still be safe. MCX press offers a remap of the MCX ecu that is suppost to...

Hi! My friend dimebag gave me an Innovation AFR gauge kit for christmas!! :jump: So now I wonder what manual boost controller I should go with. Dimebag is using a Voodoo controller, it works great but you have to loosen a set nut in order to adjust the pressure which basically isnt a...

Hi guys! I`m discussing the oil lubrication system on the Nytro in a Norwegian forum and I need to know a few things. I recently rebuilt dimebags engine so I should know how it works but I don`t feel 100% sure. My understanding is that the oilpump gets its oil from the oil tank through...

Hi guys! I am considering installing an AFR gauge one my Nytro and I wonder if someone know of a decent gauge mount for two gauges? (boost and AFR) I remember having seen one that was screwed onto the handlebar bolts but I dont remember the name of it. I want it to look professional and...

Hi there! As the topic sais, are there any common problems with the Nytro? Its always good to be alittle prepared and know what the problem could be if you are in the middle of nowhere. I think Dimebag and ntm can say a few words on this subject cause I know that they are high milage...

Hi guys! I`m about to finish up my yearly preseason check-up and having heard of the bad OEM exhaust donuts I wonder how big a risk it is to run the stock ones? If they start to leak, wount I hear it?? I already had the tank off to change sparkplugs and inspect turbo/hoses etc. and now...
