How can I tell what size my engine might be by just looking at it. I do a have closeup of the engine cylinder head posted.

Thanks in advanced.

 

I dont think you can tell just bu looking at it, but if you take the head off and measure the inside, we can tell you.

 

I did discover it is a stock cylinder head. I found 246cm3 stamped at the bottom. How big can you take a stock cylinder head? Whoever worked on it engraved their company and initials on it. I know it has been ported. I saw that when I replaced the reed valve.

 

What do you mean "How big can you take a stock cylinder head"?

Are you trying to find out if the trike has a stroker kit in it? or what?

 

I was just wondering what's the biggest bore size a stock head can taken to.

 

I think he's wanting to know how big a bore you can go with a stock cylinder.

 

usally 270cc you can go 295 or so little more with a new sleeve. they usally run hot cooling probs
