Hi guys-I'm a new member from Florida trying to restore a old sears roper 2 speed. I have everything but the Sprag gear and have no idea where to get one. If anyone has one or a source , that would be awesome.
Thanks in advance!
Working on a Fox Trail Tramp/Trail FX.
I found this clutch: https://www.OldMiniBikes.com/Max-Torque-Dual-Sprocket-3-4-Clutch-for-Two-Speed-MiniBikes.html
I am thinking about trying to get it to work on my set up.
Fox Spoke wheel bike as mentioned with a Tecumseh HS40 motor.
I always thought the design and implementation was super slick but I have never had a chance to
see one in real life or really talk to anyone that owned one. Seems like a great idea for a rugged long
lasting two speed transmission functionality ! ?
This is, I believe, the swingarm from a TrailHorse. The two speed and one jackshaft plate is included. Two speed seems to function correctly. Sprag sprocket locks one way and spins the other like it's supposed to. Axle adjusters/tensioners are in good shape and complete.
$165 OBO plus shipping
I am working on a TrailBlazer with the 2 speed, the secondary clutch says Comet. The primary I have not had off yet but believe it to be Comet as well. Engine is Tec HS50.
Will be replacing the 2 short chains tomorrow.
My concern is that the primary clutch floats on the engine shaft and did not...
I picked up these pieces separately, but they're made for each other. The Jackshaft 2 speed looks NOS, new teeth, everything looks great. The clutch is used but the shoes have lots of life left. Nothing is stuck. The inside of the clutch has slight pitting on one side, but I doubt it would...
I'm building a mini for a 6 year old. I only want the top speed to be around 20 mph. Right now he has an electric mini which tops out at 14 mph so I only want it to be a little faster for now. I will be using a Briggs flat head engine I believe is 3 or 3.5 hp. What's the best way to do this?
yep you read it right...looking for some high speed or worn out TH forks as long as the tree plate and handle bars are in good shape,, to make shipping easier hacksaw or sawzall the legs off at the bottom of the tree plate..
A couple of days ago I packed up my 12 year old's XBOX and put it on Craigslist. He played that stupid thing for 4 months straight, nonstop (he got it for Christmas) and I was just plain sick of it. I threw him $200 cash and he moped around for a couple of day shooting daggers at me with his...
What is typical idle setpoint for a vintage 1980 H50 (adj. carburetor)? Minibike Service Manual indicates 1800rpm for float-type carbs. This seems extremely high. Just looking for what others have had good luck with.
got this from original owner, but now going to move it, id rather mess with MINI bikes than Honda's etc
it is the hard to find 4 speed, I have known the bike for a few years, and it doen run fine (I ordered a new battery) and will fire it up this week, it is 100% original, only problem is...
Looking at one of the new HH60 motors I picked up last weekend its got this throttle control on it:
That is a heck of a lot simplier than the massively hard to find 30199a part and its accompanying levers, springs and doodads. Just bolt it on with the head bolts. Done.
I picked up an engine because it had this 2 speed on it. It has no markings as far as I can tell. it's 3/4" bore, but only the inner portion is keyed and the outer portion rides directly on the engine output shaft. The bell is 3.15" in diameter and appears to be much thinner than any other...
NOS comet 2 speed jackshaft, I checked everyones BIN prices on ebay, $149 shipped is the cheapest right now, you can have this one for $120 shipped via priority mail. Barn fresh (for real) from an ex-kart mini bike shop
