need 250r motor help!

[Air-cooled-R]

I'm in the process of rebuildin a 82 250r of mine and cant decide on what to do with my motor. I think I'm going to run my 300 top end but it needs a resleeve, though I do know where another 300 kit is minus a piston. I know am pissin in the wind tryin to find a head for my mugen cylinder but I would like to run it. I'd like to put a fl350 cylinder on but im still indecisive on cutting cases and all that fun stuff. Another option is a cr480 swap but I'm havein trouble findin a motor. The way I'm seeing it is that its gonna cost a nice chunk of change to do any of these engine combos so I'm open to suggestion. I dont mind the stock 250 cylinder with all goodies on it, but I am wanting to be able to wax the floor with the the 396x my buddy is buildin. what do you guys think?

Here is a brand new 300R kit for auction on ebay. It says it's for an 83 not sure if it fits 82. But it will be a chunk of change.

Yes that will fit the first gen. 250R.. Its only 50cc's but man they they realy rip!!!! 200xman had one on his fat tire R and it freakin flew.. That one on ebay is at a REALY good price for a complete NOS 300 kit.. Ive seen them go for a grand.. I just sold my 300 cylinder and head for $125 due to the fact of not being able to get pistons, and the hole having it resleeved idea turns me off.. By the time you have it resleeved buy the piston rings and what have ya, you'll be pretty colse to to the cost of this NOS kit.. I think the guy that does the resleeve set up for these also has to cut the cylinder down too due to the new piston being shorter..

how would a good dune/drag porting help the 300 kit. Ive run the 300 before and it was fast but im wanting more. Im thinkin port, head job, 38/39m carb with my cone pipe

Talk to 1upfront, he has an 84R that's a freakin missle.

Now thats interesting. How high you think it will go?

What piston fits the 300 kit? I thought there was one available? I would love to do a 300 kit on mine. IT seems like around here the air cooled R's get no respect, hardly anyone has them and when people hear about them they don't think much of them, like they are a kids bike or something. I want to show them the potential of them. I've got a sectional pipe for mine that I have not installed yet.

shawn, I tried talkin to 1upfront the other day, but Im still waiting on a reply. Anyone have any other suggestions? Also, anyone know who can do a good job resleeving the 300 kit I have now and making a piston work in it?

[cr480r]

whats the deal with a mugen cylinder? are they fast? couldn't you have a new head made?

why do you people wet yourself when a 300 is for sale...THEY CAN STILL BE PURCHASED...geez

contact LA sleeve, they don't cost that much. a new sleeve and piston...done.

when you call them, they refer you to someone else...if memory serves correct. the third party does all the work.

Well if I want I can put CR500 engine in my 250R. If I want I can put a YZ490 engine in my TRI-Z. The fact is an NOS Hondaline bolt on kit will bring alot of money, it's convenient and don't forget the cool factor.

[The Goat]

Don't get me wrong, I understand the importance of nos...

I don't understand when people spend big bucks on a worn out 300r kit when a new one is still out there to be purchased. Also... Aircooled guy did request another source.

Buying the best is one thing, buying an inferior product that has less support (meaning lack of pistons) for more money... That's a whole new animal.

ok then the question is is where can i buy an off the shelf 300 kit then for the aircooled i have been unable to locate one?

[The Goat]

contact LA sleeve....they'll hook you up.
