250-500cc Anyone making a 300 pipe yet?

My OEM pipe is hurtin' for certain. About to go in for dent removal process #2. Hopefully it lasts until the end of summer.

Any word on a 300 pipe?
Will the 250 pipe fit? I know they're different, but that doesn't mean it wont work.

I have been told that PC built a special pipe for Glen Kearneys 300, but I am starting to call BS on that rumour. I bet an FMF Gnarly for a WR250 would work just fine.

KTM 250/300 and GG 250/300 share the same pipe.

I've got a repaired stock on you can have.

You guys are too good

My pipe is still kicking, but I fear its days are numbered and I dont want to spend a fortune on an OEM pipe.

I'm ready willing and able. You guys know how to get a hold of me



EFR boys trip weekend of June 12th. Got at least 15 confirmed and it will be epic. Invite is open

pipe

i would call pc and ask, a 20% increase in displacement would warrant a new pipe. 200's aren't using the same pipe as a 125... wouldn't hurt to ask.

But the 125 and 200 have a different stroke. I wonder if the pipe is tuned more for the stroke and that is why many 250/300 pipes are the same? Does the stock 300 pipe have a different part # than the 250 one?

This subject gets brought up a lot on the TT yami 2 stroke forum. I've got a mildly ported 285 jug on my YZ and I run an OEM pipe. It works just fine IMO. I'm sure the power can be altered with a different pipe, but I dont think peak numbers will change much. Or I could be completely wrong. Since no one makes a 285 pipe I'll never know.

I would imagine the same goes for the 300. A 250 pipe works fine on my 285 and I would guess a 250 pipe would also work on a 293cc Husky motor.

I'd like to try anyway..... even if it changes the power delivery, I might like it.

I'll go out and look for a p/n stamped on the pipe in a bit.

If the 09 parts manuals are on line that might be easier. Not that they are totally accurate.

Here's what makes me doubt that the pipes are identical:

The WR250 to WR300 conversion kits include a pipe.
Now granted that may mean converting an '08 or older WR250 to a 300, and the '09 pipes could still be the same,....I don't know.

Might be worth going to Hall's on-line micro fiche and comparing P/Ns.

Is it polished? Might be a reflection...




Later,

The 300 pipe looks smaller than the 250 pipe in my eyes. This is what is making me think an FMF pipe from a 250 will work just fine.

The 300 uses a CRD pipe that is built for Husqvarna.

20 % increase in volume -displacement is a lot on a 2 stroke. example, is the pipe on a 200 ktm the same as a 250.. nope... when in doubt, pick up the phone and call pro circut. they still do custom pipes. or yours could be the development mule... for a discount. never hurts to ask.

Somebody made one for Kearney...

Damn you Kearney :foul:


Thanks for posting that. Looks like I've got an email to send to Pro Circuit and I got a pic to attach too

Let me know the outcome of your communication with Pro Circuit... I'd like one of those babies too!

I'll bet you that pipe is for a WR250...
