Agreed. I can attest that it performs. Super hard pack roads or snow you may need scratchers. But 99% of my riding it works awesome

Thanks! Been fun getting some new riders introduced to the sport this winter.

What kit are u running? I tend to follow the Timbersled recommendations for strut length. If you want less ski pressure or more playfulness you can shorten it a little but not too much. It goes a long ways. Tss pressures can vary. Are you running the new QSL version? What is your fork setup? Play with the heights and rebound speed(faster) for a more playful ride.

@@TrevynNewpherits a 2020 riot 120LE, with the original non qsl version tss. Last year was my first on a snowbike and did not want to mess with too many changes as I was learning. I realised later on, the setup from the past owner was probably not ideal. The track was touching at the back and the front was still probably 5/8s up. It was a pain to stay on the bike when moving at a crawl. There was too much ski pressure. I think I will give it a go with the track level to the ground and about 350psi in the chamber. When pressing on the fender, there is still about half an inch of travel on the tss. I also am trying 0.70 springs on the xplor forks instead of the stock ones. Thanks

Nice. They are super fun. A 120 model would work well I would think for your snow pack and elevations.

I just ran a big zip tie around it and the louver. I had a shield(plastic material) between the two so snow wouldn’t be hitting the coolant bottle also.

Thanks Bud!

Really depends on the settings and the environment and lighting. I've learned how to use the camera better now and it's adequate the majority of the time. I will say the bit I have used a Sony A7siii or A4

I like the PST intake

@@TrevynNewpher any problems with snow ingestion?

@@dirtastegoodI disassemble my airbox to help evacuate snow better. I haven’t had issues with snow ingestion. Bike breaths well even on the deepest days. Make sure your pre filters are kept fresh and tear free. I did have a day last winter where conditions were extremely humid and an ice layer built up on the filter causing the bike to not run properly. Very unique conditions though. After ultra deep days I sometimes like to change my oil just to make sure no excessive moisture is sitting in the motor.

My motors have just been freshened up and I’m ready to assemble here soon too! 🤙

@@TrevynNewpher Nice, where are you? I'm in BC (Pemberton/Whistler)...should ride together this season!

I'm in Colorado. A bit far from BC but I definitely have BC on my list @@letsdosomevideo

It’s more than just a lighter bike. Less rotational mass in the motor makes for a much more maneuverable machine and the power delivery is explosive and fun.

Personally I run the same jetting winter and summer. I don't touch it once I have found the proper settings for my elevations. In the summer the air density is lower and I generally ride at lower elevations. In the winter the air density is higher and I usually ride at higher elevations. If I drop below 5k feet I sometimes will mess with it. but I find my settings work well for 5k-12k summer and winter usually.

Get one! My GasGas ec300 rips!

Yes

HMU!

Accessories that bolt down through the tunnel have to be strategic. XRT does make different shape and type exchangers to try to work with your accessories. They also make stand offs to allow for some clearance for fasteners. I choose to mount my accessories from the sides of the tunnel. Most of the timbersled brand accessories mount from the sides.

I’m using Mikuni jets. I tried the JD kit but went back to Mikuni. Ktm Needle - 42-75 top clip Main - 400 Pilot - 22.5 I run the same summer and winter. Higher elevations and denser air in the winter, lower elevations and less dense air in the summer. Seems to work great.

Ahh… thanks Halea! 🤗

Thanks Jarred!

It’s a yz450f. I’ll do my best to keep the action coming!

Thank You! 🤜💥🤛

Are you using the same bike for summer and winter? If so, what type of riding do you do in the summer? How experienced are you at efficiently working a transmission and riding a moto?

Needle - 42-75 top clip Main - 400 Pilot - 22.5

Wow, I must be way off then. I’m way richer than that. I would have thought that would be way to lean for the main, but your bike sounds super clean so can’t argue with the results.

@@ryanshanks2136 I ride at 8-11k feet generally. Though I’ve ridden as low as 6k. In the summer i run the same. My egt has never gone over 1,200°

@@ryanshanks2136 also make sure to do the Jarvis mods to the mikuni carb

I did the Jarvis mods already. I run around 5000-6000ft and was running a 480 main because I didn’t want to be too lean, it had a 460 in it for a summer setting at 2000ft. I could tell it was really rich from upper mid to top end. I ran a smartcarb before and it ran good at times but was unreliable as it would flood out the bike a lot and leave me stranded in tough spots, so I’m just gonna try to make the mikuni work.

Thanks! This is near Steamboat Springs, CO. 2019 KTM300xc and a 2023 Timbersled RIOT3 Pro

I like how maneuverable the gnarbike is. it's the tightest turning and most nimble snowbike I have ridden. It can be a handful in steep gnarly terrain as it will loop over pretty easy. Especially his short track version. I would like his setup to be narrower as well. Timbersled feels familiar and I like being able to convert in the summer back to tires. If I had excess money I would certainly consider having one of his bikes. With some clean finish work and other refinements it could be a really sweet setup for sure. Opening doors that traditional snow bikes dream of.

under visor mount typically. that's where this is shot

Definitely depends on how the bike is setup. My 300 out pulls most 450s I’ve ridden. Have to shift more often but it’s definitely more fun than a 450 IMO
