Does anyone know if the 125D barrel will bolt onto the 125E/F bottom end, and if so what the porting differences are? Cheers

D & E are pretty close to each other and probably wouldn't be any drama but there are a few changes between the E & F though and interchangability is doubtful.
-
I know the E/F barrels interchange, the porting is milder on the E though and the exhaust mounts differently. If you reckon the D/E interchange I should be right to fit the d barrel to the f. Any idea what the porting characteristics are like on the D model?
-
E is better.
D is peakier without any positive trade-off, and the big single intake port wears rings out quicker.
I'm told that the F barrel is super-peaky, but at least makes a stack of top end power to ease the pain. F barrel needs F pipe due to the different spigot on the exhaust port.
E with E pipe = Win.
D with E pipe = good.
D with D pipe = pretty good.
F with F pipe = fail unless you're really good.
Dunno about E barrel with D pipe, but it seems pointless.
-
don't suppose you've got a spare E barrel lying around do you?
-
They are all interchangable but I agree the E is by far the best all rounder. as for the pipes, they are all different as well. I am using an E motor in an F frame with the F pipe using silastic to seal against the flange. There are many differences but lots of interchangable bits and I hate typing. Give me a ring if you want more info. 0427 334186
Evilbay has barrels from time to time but if you are desperate I reckon I have a spare or two

not too bad a price I suppose? The postage is the killer though (that and the exchange rate)
-
That NOS item is a bargain. Stop being a tight arse and buy it now ;)

it's only a nos piston you dufus ::) ;D the barrel and head are used.
-
meh.....still a good deal. Have you priced having a barrel sleaved :o :o
That guy always seems high on postage for some reason. Possibly where he hides his profit margin ::)
-

no, is it more expensive than having one re-sleeved? ;D
-
My 250 quote was $570 plus postage. That would be plus piston etc too.
-
well, this guy says it's on 2nd oversize,
but he's throwing in a 3rd oversize piston kit in the deal.
so after you've added the cost of postage to your doorstep,
you've either got to source a 2nd oversize piston kit if the bore is ok, $$$
or,
bore the barrel out to the 3rd oversize, $$$.
and if your happy with all that then whats the problem.
-
Get him do do a revised quote on the postage. I reckon it will fit in a preapid up to 20lb box for $45 USD
-
thanks Neale, I sent him a message yesterday but haven't heard back yet. If he doesn't budge I might be calling you ;D
-
hey nathan don,t no about the barrels but you wouldn,t no where i could find a rod . my limited internet skills keep coming up short . are the d,e,f same rods as each other
-
Sean, All of the YZ125 up to and including the 125G have the same rod.
Rod from a DT125/175 (up until the safety seat model), AT1/CT1 also work perfectly.
-
IT125 & IT175 Also
You can always pick up an IT kit cheaper than a YZ on ebay
They are still available new from Yamaha but are expensive
Latest part number for a kit 3R2-11650-00
Check this one I am 99% sure they'll fit

Says it's for a DT125 81. Ring local Yamamy joint ask what part number yours supercedes to then ask them what part number the DT is. I reckon they are the same. NO
Garantees though
