Interesting video Rapo, that's a nice machine you built. It breaks trail pretty good and looks like a really smooth ride in the powder. I was looking at the docks along shore cranked halfway up, at night you could get clothes-lined pretty bad by the legs.
You could get clothes-lined on any machine and that would not be good. Gam
Yup, my snowsled is what I had in mind.
Nice video and you do exactly what I do, make your own track rather than ride in uneven existing tracks. It does appear your home made dog is lower to the ground and might have a lower center of gravity. A couple spots where you were off kilter I think my Snowdog would have wanted to take a trail side nap and I absolutely don't like the way you have your auger blade mounted. Mine rides facing north and south either in a sled behind my dog's sled or on top of the motor unit just in case I do flip over. I do wonder of mounting a set of snowmobile skis on each side as outriggers might help when we do get on a tilted slope or in deep ruts made by other machines. I was out yesterday on a local lake with no snow on top but lots of ruts left from other machines that were out on it when the snow was soft, it was a workout unless I was cruising along pretty slow. I did find a couple spots that were perfectly flat where I could go full throttle. If 20 MPH is full speed then I hit it a few times and can tell you that is plenty fast enough and I would not want to go any faster ever.Gam
From the cvt sprocket to the next big sprocket on the original drive where the torque converter was.how many tooth sprocket are you running?i build briggs,tecumseh and predator motors and hop them up.ive got a 5hp briggs modded with a light aluminum flywheel hi compression piston,bigger valves and valve springs,racing cam,pipe with 1” crankshaft so i can run the 40 series cvt.its probably 10hp now.i just need my snowmobile chassis.im guessing 72 tooth or more on the big drive sprocket?im fine with torque over top speed.to small of gearing will burn belts up.been there with the mini bikes I build.
Lol i just know that too small of jackshaft sprocket where the old snowmobile torque converter used to be with the original gearing from the snowmobile drive will burn up clutches and belts.i just need a ballpark of number of teeth to start with.i know the cvt drive is 10 tooth for 40 chain on most setups.
My buddies on the Yamaha TW forum helped me with the gear ratios once I got involved with these Big Wheel Yamaha's that have 2 chains and 4 sprockets. The final ratio to the ground was a bit mind boggling for me and I could change just one tooth on one sprocket and make a huge difference in the final drive. Jack Shafts change all the final drive ratios and I don't even know how to figure in the CVT belts that ride higher with engine RPMs. Back in the late 1960 s I used to be a real smart ass with this stuff now in my late 60 s I have become a real dumb ass. 14 teeth on the engine to 17 teeth on the inner jack shaft over to 13 teeth and back to 37 on the rear wheel and I get lost somewhere in there. My BW350 has a 530 size chain and sprockets on the inside and a 520 on the outside and I can't explain why. On my Polaris ATV/UTV machines they all had big rubber bands on the CVT pulleys and I never did figure them out and never did burn a belt.Gam
Damn Doc, you just had to go and get all technical on us. I used to do all the sprocket play with my dirt bikes and to be honest I usually found the manufacturers got it as close to correct as most riders wanted them. I ride a Yamaha BW 350 these days that came with a 37 tooth rear wheel sprocket but I swapped it for a 43 tooth and those extra 6 teeth sure do make a world of difference but mostly in the low end grunt. Not sure if these track tow machines will benefit much with more low end grunt on ice or snow unless you stud the track with some real heavy grippers. I don't know what most snowmobiles use for the tracks width and length but at 20 inches wide and I think close to 50 inches on the ground I have about as much under me as most snow machines. Studs do add a bunch more grip but in the worst conditions they can dig a hole instead of get you out of one. I honestly think it is all about what you get yourself into and how you get out of it. Too much power or too much traction could probably tear the track to pieces if you push it too hard. I have had my Big Wheel Yamaha up to the sprocket in sticky mud and all I could do is go for help.GAm
I think I’m 12 tooth on the comet, going to 72 on the snowmobile jack shaft. I started with a lot smalle sprockets and eventually figured it out after burning one belt. Torque troque torque.
ive had pretty good luck with the cheap china comet knockoff torque converter systems on the predator engines. ive installed 5 on the baja warrior and baja heat minis.probably use one of those on my modded briggs to start with.they have 30 and 40 series comet knock offs.
My bad.i thought the 1” shaft kits were 40 series but are just hd 30 kits.dirt cheap tho.ive ran these on predator 6.5 engines with no problems.but that on fat tire minibikes.https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F181538048087
I would NOT use the 30 series if I were you. 40 series is what I should have done. As much as myne functions, I usually run without the cover to keep the heat down. Use in warmer temperature’s is risking the belt even at my current gear ratios. Also I’m worried I am wearing out the weights on the inside of the clutches prematurely. Also I’ve broken the end of one of the springs on the driver which caused me to loose neutral. I fixed it by just bending a new “hook” end on the spring and re-connecting it.
So I have a brand new Snowdog. Love it! The only negative I have found so far is the sled. On glare ice, is there a way to make it track better? We don’t get a lot of glare ice here, there is always some snow with the exception of my favorite lake! Just a lot of issues with he sled sliding out as we were moving around. If the snow dog were studded, resulting in a better track, would that work? Seemed like the sled had a mind of its own regardless of what the dog was doing.
Howmuch gas does the 13hp standard hpld ?
