Alternate 4-stroke engine list

**BarelyAWake** · #1 06-09-2010, 03:32 AM

Hey all, I've been on the quest for an alternate 50cc 4-stroke engine complete w/electric start & internal gearbox for my next project and wouldn't ya know it - Crazyhorse is already all over it lol (no Red, I'm not thinkin' a choppa heh)

build thread: http://motorbicycling.com/f40/xl-cho...ike-18970.html
engine: Loncin Engine - 110cc Dirt Bike - $139 SPECIAL 70cc Engine Complete - Full Auto - No Reverse - $139.00 - HighRpmRacer.com

Still, finding just the right engine for your needs can be a bit of a challenge - while I've not found a vertical 50cc 4-stroke, I figured I'd post the list of what I've found with prices & distributors (although I dunno if they're trustworthy as I've not done business w/them yet ofc). So - if ya know of any 50cc 4-stroke engines w/internal gearboxes & electric/kickstart (horizontal, vertical, auto or otherwise) please do add to this list!

Here's a link to Lifan - although they don't sell direct, it's a good place to get engine model numbers to search for.

"My next project", huh! So, is this a sneak preview of what's coming next winter? Got the bike yet? Come on, you can tell me. I won't tell anybody else. Trust me! It's a cruiser, right? Vintage, of course. Another Rolls? Come on, man, tell!
That Lifan engine is sweet. This will be a good resource thread.

Ah,
Well, that clears that up. So it's a definite maybe. Whatever it is, I'm sure it will be interesting and a lot of thought will go in to it. I guess I can wait if you can...

I like it when people dream out-loud.

BarelyAwake, awesome idea for adding an alternative 4-stroke thread.

Guess will have to start adding info as people request such as what one needs when they purchase this style engine, ie wiring harness's, carbs, 12volt regulator, cdi relay, ignition coil, etc etc....

Maybe some of our sponsors will add this type of engine to their own inventory, for us interested forum members to purchase from them.

Kudo's to you BarelyAwake, for making our forum a lil better everyday!

Peace Crazy Horse.

Good stuff! ALWAYS looking for alternatives, it's what I do!

Hey Helmutt, Hope all's well! Still want to do some frame stuff just tied up w/ other things! You know how it goes.

Anyway, good thread, love where this is going!

Cheers! Evan.

Good Idea I have been dreaming about a 4 Stroke 4 a while. This is definitely where I am going with my next build!
