Can you mount these engines vertically?
I'm guessing 'no'... 4-strokes usually carry their own oil inside the engine, & tilting it would mess with the oiling system.
if the carb has a float bowl then no not without fabricating an intake manifold to keep the carb oriented properly . is it a 4 stroke ? most 4 strokes have an oil reservoir designed to be in the position that the motor is intended to be at , so there's another no
if the carb has a little bulb primer pump , it may have an all possition carb , if so then yes
being a little more specific with your description of the engine you are asking about , might help in getting a better answer to your question
Heres a link to the engine IM thinking about
LIFAN 125CC ENGINE MOTOR HONDA CRF XR 50 XR50 CRF50 NEW : eBay Motors (item 320474585652 end time Jan-20-10 18:20:51 PST)
looking at the motor i think most likely no you cant mount this vertically , but i could be wrong , and not being able to see the other side , its possible that the chain or belt comes strait out the back , which means vertically mounted the chain will be coming out the bottom , and thats a whole new problem .
That is a pit bike engine! With a four speed tranny! It would definatley not run horizontal... I dunno why you would want to those motors are like 2 feet long. One of those on a bicycle would do 60!
p.s. they are also waaaaaaaaaaaaaay to heavy for a bicyle they were designed fer quads and pit bikes!
I am building the frame from scratch. I want to use one of the lifan vertical engines, however I can only find the 200cc available in stock right now and I dont want 200cc!! Does anyone know where to get the 100 or the 150cc lifan vertical that is in stock right now?
 having trouble finding under 200 too....have seen a lot in the past
No... you have to mount it the way it's pictured!
Here's a place to look.

I can't find many below 200cc either, but I can tell you that the horizontal works great! I have an automatic 50cc mounted on a stretch cruiser. If you are building your frame, it should be an easy fit. Truly hauls butt.
Got some picks of your finished stretch?
I'm thinking of building one myself.
It's not completely finished, but ridable. All of the pics I have are in the DIY area under ATV 50cc thread. As you know, it's been really cold in Alabama lately. I am too cheap to spend the cash on heating my shop, so I am on hold until it warms up a bit.
Hey aero, the holidays are over, finally. Let me know when you get some time that we can meet up!
I’ve got a 125cc engine that came out of a brand new Panterra dirt bike. It is the about the same size as the 150cc, 200cc Lifans. It is an electric start, 5 speed vertical engine. It is complete except for the carburetor slide. I even have the coil, cdi, exhaust, air box, etc. I pulled it from a bike that I converted to electric. It had 1 mile on it. I’m near San Luis Obispo, but I get down to the LA area once in awhile. Make me any reasonable offer and it’s yours.
I see Hooper is now offering the LIFAN vertical 100 cc engine at a sale price of $299. Ive also, been considering this for my BTR.
