speed and sport inc have a brand new one... its only $670 USD

ouch!

[Freakshow]

the monoshock DT125 barrel and the YT125 trike barrels will bolt straight on but have the disadvantage of having smaller reed blocks making the rubber boot to carby/set~up a bit of a challenge.
not impossible though.
but a well sorted DT125 barrel could be quite nice too.

I have some Dt125 barrells, maybe an X and maybe a MX125 if you get stuck.

Needs to be a YZ-D/E/F, IT or monoshock DT barrell to fit the cases.

The IT125 and YZ125F barrels also require a different exhaust/exhaust mods.
The DT barrells have a smaller intake/reed block which won't accept the YZ carby.
The YZ-E barrells look different from the outside, which gives them away as being not-pre-78 legal (if that matters).

freaky
i keep on seizeing my x might need an x barrell if you have one

[Freakshow]

Small world Phil.

Good luck at the Nats.

Nothing better than riding a 125 dinger on full song.

A small world indeed!I have just spoken to the tuner,and he is very happy,bike has gone from 9hp at the rear wheel to 19hp without going down the methanol track.A very big thanks to you and everyone involved in getting me the cylinder.I recon I may notice some difference! Now all I need to do is find 4th gear for the 250!
