250R questions

[firefirefire90]

This will be my question/picture thread for my 250R.


My first question is, what type carb is this? It is a Keihin PWK 72RA3 LL

Is this stock? It says "motorcycle race use only" on one side and "Sudco Racing U.S.A." on the other.

More questions to follow. Thanks!

72R means its a 39 mm, not stock for any R trike. Post a pic, could be an airstryker but I don't know what numbers they have on them or what the LL means.

Alright i'll try

My camera is sucky right now.

Does this cylinder look big to you or is it just me?

Is this a progressive rear spring?

Definatly a 39 PWK carb, Looks like you have a bigbore pro-x cylinder as well. The spring looks like it came out of a 88/89 trx, also looks bent in that pic but could be an illusion.

[firefirefire90]

Yeah its not bent. Illusion. What type of cylinder? 310 or something?

[x.system]

You would have to take the head off and measure the bore to find that out. If its an o-ring head you can pop it off and right back on, if not you will have to get a gasket but it doesn't look like theres a gasket in there from your pics. I think 310 is the most popular so I would guess its close to that.

[firefirefire90]

Its wierd...I did look up Pro-x cylinder on google and it looks JUST like that. But where are the CT markings?

[x.system]

If it has any markings at all they will either be under the intake (Paul Turner scribes the specs there) or inside the cylinder itself. Some don't have any markings at all until they are ported by a specific company. Somebody could have bought that cylinder from pro-x and put it on without having it ported. CT buys their cylinders from pro-x and then puts their markings on it if they port it.

Is that rear spring PINK? It looks like It could be a Progressive.

[firefirefire90]

Yeah its like a very very light red...i guess its pink. But not HOT PINK if that's what you mean?

Welcome to the R Club again.

Its good to be back!

Hey so where can i find a new sprocket for this thing? Also chain? Do they make custom chains for this? It has a +4 swinger. O-ring chain would be best right?

[200x newby]

X-ring chain is supposed to be the best more expensive but better.

[firefirefire90]
