dg head or not

[md2drag99]

i know this is the dg head it came off a fl250 but will it also fit the 250r? and the guy that has it is wanting $200 little high i was thinking

[Twilight]

that looks like ass if it came off a fl250, after 4 years of running mine it had small blackness and barely any pitting,

[1upfront]

It looks to be a dg.

[NINJA]

Yeah, that sunburst head will fit your 81-82 R with no problem, the 83-84 R though requires you to shave the fins down in one spot a little bit. It doesn't affect it's performance any. $200 is too much, especially now, no more than $125 for that one.

[Twilight]

I wouldnt pay 100 for one in that condition. It is a FL250 DG head though. Try to lowball him, a like new one is 250 or so.

[1upfront]

The fl250 only has 4 cylinder studs so it wont bolt on an 81-84 atc 250r which has 6 studs. The other holes you see are for dowel pins.

My bad, I didn't even catch that when looking at it! Good call. I was thinking of the sunburst head from an 81-82 R going on an 83-84 R. Doesn't the FL250 cylinder swap over to the R though? Also, from the top that head has provisions for 6 studs correct? You'd just have to drill the holes out larger right?

[Daddio]

1upfront knows his Rs. It wouldn't be worth the trouble to drill it out. All six holes would have to be drilled. The pistons will interchange though.

[NINJA]

I know the pistons will interchange. Will the FL cylinder bolt onto the R bottom end though? So the bolt spacing is totally different on the head? I'm just curious because I've had 3 of the DG R heads pass through my hands. I also love to know what can be swapped with what and what can be adapted.

[freaksfix]

I think the FL jugs will bolt on to the air cooled R but the exhaust port come out at an angle so mounting a pipe would be a problem

[1upfront]

The fl350 jug will bolt on a 81-84 250r bottom end if the cases are bored for the larger sleeve diameter but I don't know about the fl250 cylinder bolting on, it wouldn't be worth it anyhow because the fl250 was a non reed valve motor and they don't make as much hp.

[NINJA]

That makes sense.

[Twilight]

Stock FL250 was around 23HP, But I could see the FL350 jug working well.

[Yamatrike400]

Stock FL250 was around 23HP,

That's the same as a stock 250r ain't it?

[1upfront]

The 83-84 250r had 29 hp stock the 81-82 had less because of the little carb.
