Good stuff. Im going to keep my eye out for a 250 four stroke bike engine. ---------- Post added at 08:01 PM ---------- Previous post was at 07:58 PM ---------- What's the displacement in this Kawasaki motor?

Thanks. I was looking at step bits and the graduations seem to be about 1/8"...so not good for 3/16" stock. I guess I'll just buy 1/2", 5/8", 3/4", 1" twist drill bits.

Have C25 gas all set up. Part should be here soon and we'll be cutting and welding this weekend.

Jeez...i never knew that. So you'd need to reuse the bike exhaust/muffler or have a custom one made...hmmmm....there are not off-the-shelf pipes for this motor? ---------- Post added at 09:03 PM ---------- Previous post was at 08:58 PM ---------- Okay...so switching gears to a four-stroke (no...

Got welder rigged up... somehow missing the gas dispersion thing in the gun nozzle...so....no welding today. Got a little propane Mr Heater set up in garage. 15 degrees outside and Mr Heater only got us to maybe 35 inside.

Slightly rusted flywheel magnets/bad coil gap? (Thus your weak spark) It should be fat and blue. Also, is it real easy to pull starter cord? (Poor compression)>>>bad valves or bad head gasket?

All tooled up: New Lincoln 180 MIG welder, torch, tools, etc. Made 4x8 fabrication table. Picked up steel two days ago. Will start doing some practice welds tomorrow since its been quite a few years since last welding. And hopefully we'll be cutting frame members in the afternoon. Motor...

Assuming i could find a CR125 or a CR250 engine used, for reasonable money ($500 or less)...which would be a better option for some fast fun...not looking for race class compliance. Is the 125 too finicky with narrow power band? Would the 250 be easier to just run stock? Is a early 2000s...

This world of shifters is pretty confusing for the neophyte. So here's a guy with a decent racing shifter, a 125cc two-stroke, and his kart appears well set-up. Apparently this is a 125 from a Honda CR125 dirt bike. https://www.youtube.com/watch?v=hsgQoLMMEoY&t=96s As he describes it, you...

Hmmm...I'm not sure what that means. The title says "4 stroke vs. 2 stroke"...but the clip doesn't explain anything about the difference or explain what the guy is running on that kart.

Is a 150-200cc 4-stroke dirt bike motor and transmission going to move a 200 pound rider on an older racing frame....like 70-80 mph top end? Whats the top end of a Lifan 125 on an older racing frame? roughly.... thanks

That's a nice looking frame. I'm going to check that out later. ---------- Post added at 11:34 AM ---------- Previous post was at 11:32 AM ---------- I have a bunch of Lenox and Milwaukee bi-metal holes saws for wood. But I know from experience that even hitting a (soft) nail will do damage...
