I'm undecided on the clutch, it's just what I saw available on Dennis Kirk and whatnot. But seeing as you've worked around these, it has a chain case, is that integral or can it be removed for roller chain to run it on a jackshaft for my buggy?

I've seen guys remove chaincases and use them in their buggies. My personal thoughts are "not worth the effort". It will require some machine work for the input and output shafts, as well as a custom fixture with extra bearings to support said shafts.

My favorite option for reduction would be a polaris atv transmission. the chain drive transmissions found on polaris sportsman/scrambler/trail boss quads are pretty stout, have reverse, and some have low range as well. The weakest point is the small diameter input shaft. But with 40hp, you should be okay.

I'm unsure of the power but you're probably right on with it being around 40hp, my guess is around 40-50hp as is, being a Suzuki Spirit engine. Surprised that this Panther was a single carb and not a dual carb like the Pantera, wonder what differences they have, maybe the Pantera was the racing sled back then?


Having reverse and a hi/lo range would be very nice. Mostly reverse. So another stupid question is, what kind of input shaft is on those gearboxes and what kind of output does the driven have?

The 90s suzuki 440 was rated at 45 iirc, with dual carbs. 40 is a guess, may be less depending on exhaust. Its pretty common for the lower end sleds to have single carb motors. Arctic cat did that for years, panther was the economy sled.

The polaris gearboxes have a splined input, requiring you to use a p90 clutch system, or machine an adapter. The output is chain, 520 i believe. Lots of different sprockets available. Check out my buggy build thread if you want to get an idea of what one looks like.

Are you aware of any Polaris gearbox that has a chain output? The ratios for the Xplorer gearbox on that Baja look good, I would like a little deeper final drive to help a bit. Make hi range more useable and really make low range useful ranther than only sticking with low range for the gear reduction. From what I've been reading from those that use sled engines, 10:1 is where you want to be around with 20" tires, even lower like 12 or 13 to help it out.

Trail boss, xplorer, scrambler, trail blazer, and older sportsmans were all chain drive output.

 

[Kartorbust]

Good to know! Thank you

 

[Karts of Kaos]

I just got into mountain biking and was wondering if you guy new a any good mtb forums. thanks!

 

[Kartorbust]

I'd look for ones that are really active. Nothing is more boring than being on a forum where there's very little activity from its members. Just my opinion.

 

[Solomonster212]

I was into mountain biking for a while but I sold my GT Palomar and used the money for go kart and dune buggy parts. Things with engines are much more fun and faster than bicycles.

Because of Сovid in Russia sporting events and competitions were canceled, we already missed 2 kart races, and moved one race from this Saturday to the next. I hope this race takes place, and we will open the summer season

Picked this up recently. Now some argon and filler rods, and off to practicing

 

[Kartorbust]

I take it that Einhell is the European equivalent to say our cheap end welders here in the States? Seems like its priced reasonably for some.

Pretty much. They do range from hobby stuff to semi pro stuff . All in , i shouldnt cross 400 Euro for a complete setup . Thats a 10L Argon bottle + regulator + tubing , welder and all the accessories . You even get 2 tungsten electrodes , 1,6mm 1.5% thoriated ones , 2x #4 , #5 and #6 cups , and some other stuff .

Should be fine for learning. DC only , and manual gas control on the torch. ( Basically an inverter unit for stick electrodes , with a Einhell TiG kit . ) Does 82A @ 100% duty cycle , more than enough for my needs.

I cant seem to find a easilly available chart for L to CF cylinder sizes(CF is common rating here in NA for gases)... but if my search is right.. that bottle will be a short time to do not that much... probably going to need a 2.5 taller size at least to get somewhere...
I reckon maybe less than a hour, maybe about 1/2hr there abouts of weld time......

 

[Kartorbust]

I think the 10L bottle is the equivalent to our 1/2 hour bottles. Seems like its maybe a bit larger than our MAP gas and similar sized Propane bottles for soldering. A 6 hour bottle which what our 125CFH? Would be very expensive I think.

Either way, congrats on the new welder purchase. A TIG welder is definitely high on my list of tools to buy, after a drill press with an X,Y axis vise.

 

[NewbCarter]

I dont know how bottles are usually reffered to for capacity, here its either in kg or L. So, a 10L bottle, which is its physical volume, and they are pressurized at 200bar. So, unless there is more at play thats 2000L of gas for me to work with. For a flow of max 15L/min.. Id say its enough.

My new wooden kart. How fast do you think it will go?

Where's FreeRunner when you need him?

I'd probably say Mach 3.2 because science and reasons.

 

[Solomonster212]

Where's Mrmcrib212 when we need him?
