Is it safe to ride down a dirt road with a Chinese HT engine?

Hate to rekindle an old thread but this is my exact question lol

I have an old looking motorbike that I'm putting a motor on and i wanted to take air filter off since it looks cool without it

Probably shouldn't but dirt should just go in then get spit out exhaust?

not before essentially sandblasting the bearings, ports, and cylinders. worse yet, if a rock happens to get flung into there you're SOL

Kinda figured that, guess I'll pull the old pantyhose out to cover the carb

Hey, I live on a dirt road

a 4stroke can live with a small amount of gunge, heck, virtually no aeroplanes use airfilters. of course, 10,000 feet is pretty clean

score the bore, pit the valve seats, erode the plug...not that bad. all fairly easy to fix every fifty hours or so.

a twostroke...well... simply, no. not if you want it to run still when you get home. oil, fine dust and internal engine parts do not mix terribly well.

dirts roads, in all other cases...ARE FUN!
