4 stroke kit on mountain bike?

[Old Busted Hotness]

If it's anything like my old Hardrock, it won't be easy but you can fudge it in there.

Is your 2 stroke blown or do you just not like it? I would keep the 2 stroke and do some upgrades to it.

Is it possible to put a 49cc 4 stroke kit on a hard tail mountain bike? I only see them on beach cruisers and want to be sure before I purchase a kit.

Cut a piece of cardboard 8 1/2" wide x 10" tall.
See if the cardboard will fit INSIDE the frame with it being level and not too tilted.
The front angle of the flat engine mount may not fit properly against the front downtube.

Y'all must live in a dry climate.. You ever rode in the rain without fenders... LoL you get showered with wet road grit Slinging off your tires.....
I prefer a beach cruiser... You only need 7 speeds... And they have fenders.

Walmart has Planet Bike 26" fenders for $31 with free delivery. And they fit most MTB's

It’s just having a lot of problems and I’m ready for good gas mileage, less vibration and reliability. Also more your tourque

Well if you want to use a 4 stroke use a different bike or use a rear engine design.

Watch out for fender mounting/hardware tho------there are some horror stories on the forum. Art
