Picked up some inexpensive turf tires in 13x5-6 for the kid's Manco Vortex and those suckers wore through pretty darn quick on asphalt. Any recommendations for more durable tires for primarily street use?

So I have this stock older GX390 sitting around. I was going to sell it, but darnit, even after sitting over a month and a half, it fires up and purrs first pull. The vortex has a 212 on it now and does fine with a 30 series clone...but space is at a premium and I think I'd need to go clutch for...

Manco vortex. Ordered some generic front wheels with bearings exposed. If I tighten the nut too much, the bearing cover pops off and it's screwed. If I use a washer, it locks onto the wheel hub itself and the wheel won't spin. Did I get the wrong wheels? What the heck am I doing wrong? EDIT...

So short of replacing my entire axle (manco 7/8" hex) and all associated stuff, would it be possible/not entirely difficult to convert the manual brake to a hydraulic caliper/pedal setup?

Got an ebay 30-series. Came with hardware but of course the thread size is wrong. Even tried removing a bolt from the 212's cover itself and that wasn't correct for the threads? Did my 212 get tapped weirdly? Anyone know the bolt thread size on this thing? Wild. I know the shaft bolt is...

So I have a vortex frame with the 7/8" hex axle. I was able to (finally) get the old wheels off and am replacing them with the hex axle to 4x hub. I'm running into a spacing problem. The passenger side axle sticks further out than the driver's side, and the spacers are therefore showing a gap on...

Found a local deal on a running Honda 390. $150. Should I? Manco vortex would be the platform. Figure some carb jetting, air filter, timing, and an exhaust upgrade would make it rather beastly. Ideas?

Trying to remove the rear wheels from the Manco Vortex we got. removed the bolt and washer from the rear axle. Tried hammering on the tire on both sides to loosen it up, tried seafoam lubricant, nothing. Is this thing actually screwed onto the axle/hub or is it just secured on the hub/axle...

Hello folks. I'm new, and from Florida. Picked up a Manco Vortex frame and intend to build it with and for my daughter. Currently needs everything from a seat, motor, steering, throttle cable, to wheels/tires. I'm not entirely confident in the brake either.... anyway, looking for as much...
