Here's something that I found at the LB swap meet last weekend... It's a 98cc V twin with (i think?) a 4-speed trans!!
The guy was selling it for $100.
This would be super kewl in a strech cruiser!!! (^)

that is gonna be a really cool build, but i think it would make the ultimate board track build, maybe use one of pats custom frames and tanks?

if it would fit of course....

Methinks it a posuer. Front pipe looks like it's been hot, back one not, and unless there is another carb............carb intake is right up against the back barrel. Neet looking though.

Yup.....look at the cooling fins on the air cleaner housing (I mean rear cylinder), they look quite a bit different. Looks like a Mikuni carb, although it's prolly a knock-off. Looks like the ol' Honda 90 crank case, another knock-off again....but it does look cool though, doughnut? dnut

Is that really an electric starter up front there? Or is it a toolkit holder?
Is it even really a 4-stroke?

My Thoughts exactly the rear is a dummy maybe a big airbox

I wanted to see if you have done anything with that 98cc motor, if not would you consider selling it? I have been looking for a motor like that to finish my mini chopper for some time now and have not been so lucky to find one. If you would consider selling it I would make you an offer of $200.00 as you could double your money,if it runs. If not have you located a manufacture name yet.

Your unquestioned purchase and the initial reactions to it underscore the desire everyone has for a small, reliable 4-stroke V-Twin. I have a real jones for one and I think lots of others here do as well.

50cc is the current legal limit for moped engines here in Ohio, but I think I'm going to buy one of the HF 99cc engines and start with it. Anyone know a good source for 50cc stickers or decals ?

I really wish someone would design a 4 stroke narrow bank angle v-twin of the appropriate size to motorize a bicycle. 45 degrees is standard HD, but anywhere between 40 and 55 degrees should be narrow enough to fit well. Might as well make it 49cc so it would be legal as well. An oversquare design would give the best torque. 25mm bore X 50mm stroke = 49.1cc. I would guess the rev limit would be around 6000 RPM.

Perhaps if we made this thread a pole to see how much interest there is for such a powerplant, someone with the means and or connections would take note and make it available.

Who amoung us would buy a torquey 4-stroke v-twin of 49cc to power a bicycle, and how much would you be willing to pay ?

100 bux if it's made in China....that's all I paid for a 212cc Predator from HF.

The un photoshopped version of this motor (48cc horizontal piston honda) is torquey enough in my opinion. I see no need for a v twin to boost power. I have it in a mtb frame and it can do a wheelie in second gear if you arent careful with the throttle. And that is with 12:36 gearing. Not to mention with two cylinders the pistons would be the size of thimbles :p

I guess no one appreciates the v-twin look and sound enough to abandon cheap single cylinder engines. I must over estimate the interest I see popping up on this and other forums.

It usually goes something like this.....someone "finds" a previously unknown small v-twin, everyone rushes to find out about it then realizes...

A. you either have to build it from scratch

B. it's way too small (RC airplane)

C. it's got a dummy second cylinder

D. it's a new design that someone's working on and "more information will be released after we do more testing".

BTW, I don't know about anyone else, but I've got pretty big hands and a 1 inch thimble would be way too big for me. Also, I wouldn't decide not to buy a small v-twin if it was bigger than 49cc. I think someone mentioned 212cc ?
