1984 250r Perf. Modz

[bebeav]

my bro just bought a air cooled 250r.

he want to get a bit more out of it.
first the engine is now on 71mm bore size.
will soon get a dg headpipe and silencer.

i susgested him to get a 85-86 250r carb sincehe got a 30mm carb.
then get a boyseen reed cage and reeds.
and maybe a port and polish.

anything else could be done on this engine to get some more ponies.

Clamp-on air filter
Have the head milled for more compression.
Weight reduction
Re-gear it

start to sound great.
by now we got

71mm oversize piston
dg headpipe and silencer
85-86 stock carb
clamp on filter
boyseen reed cage and reeds
head milled for more compression.
Weight reduction
Re-gear it
port and polish

anything else?

I would say stroke the crank, but you probably aren't looking to split the engine cases. :confused: Deffinetly get it ported. All of those mods should be more than he will ever need. But, I can't really think of anything else.

[Dammit!]

It would be cheaper to sell it and get a '85 or '86.

That said, I want an '84 to wrench on myself so go crazy. :)

waterpumpers are not in the list right now.
i really love the air cooled R.

you think all those mod will be enough loll
power is the way to go, i'll never get enough.

i like the idea of stroking the R but i never saw any rod made for it. maybe some compagny would do it but at really high price.

any other idea that cross your mind will be greatly apreciated. i really want to get the max out of the air cooled R.

anyone ever try to fuel injected it, or any 2 stroke carburated trike??????

if it could be done i think i would really like to try to turbo it someday but without fuel injection i think it would be nearly impossible.

Give Powroll a try. They move the crank pin further out, and they shrink the orignial rod, so you wouldn't need a new one. You could also have the fly wheel lightened so it revs up quicker.Get one of them short gas cap breather tubes. You could also try finding a 300 big bore kit. :twisted:

I would be careful about milling the head as when you increase compresion you increase the heat produced, so I wouldn't go overboard on a high comp engine for an aircooled bike.

[bebeav]

how much do you think powroll would charge for job like this one.???

powroll only makes 4 stroke parts. I think there slogan is something like "Providing over 40 years of 4 stroke power"
