Reliable 4 Stroke For Long Distance

[Deleted Member 4613]

Check out this video of a 40 mile trip on a 4 stroke. It's a very convincing example
of the reliability of 4 strokes, and traveling up to 38mph, then ending with a
fill-up at an ordnary gas station. What could be better and more convenient?

I want to build a 4 stroke with a flathead soon. I hate mixing gas

But I think 2 strokes are more fun and look cooler in the frame. The 4 strokes just look like lawnmower engines

I get it that 2 strokes look cool in a bike frame, but all the trouble of keeping them going and mixing oil in the gas is simply not worth it. They break down so much, you have to be a certified mechanic to own one.

If you build a two stroke right it will run great, but they do have gremlins from time to time

I'm with GW on this a little 3hp flatty would work perfectly.

I've been on 100+ mile rides, 4 strokes will run all day
While she will go over 50 mph, she cruises @ 40 - 45 mph all day long

Man that road looks ruff sure would hate to fall down on that. Looks like it would grind down to the bone doing 30 mph

Chip seal road. She is rough all right.
No wonder most of you guys want to go fast, nothing else to do on a road like that.

The 4 strokes force air over the fins and I want to say are oil cooled as well. The GX50 clones like to be rung out, burns the carbon off, no pumps just an oil slinger run off the valve train.

The genuine models can run 10% ethanol provided you drain the carb before storing.

Relatively linear power curves provide consistent acceleration.

Go for a predator 79cc and you can use a cvt but its lossy. Lots of mods for those, throw a huge stack of cash and you can push 7hp at 9k. The gx50 does well and it is governed at peak power so you don't need to moderate your throttle, just twist and go.
