Here are some pictures of bike with my DG Head after a ride. For the people out there wondering yes it makes quite the difference (you can even hear it while the bike is idling). It wheelies even easier, spins the tires more will even lug second gear120940120941120942120943120944120945. IF YOU CAN FIND ONE BUY IT.

What would worry me is that if you are feeling quite a difference, the compression ratio has probably been changed. You may have to rejet or use a higher octane fuel to compensate. I wonder if it is running leaner and that is the difference you are feeling?

If the compression ratios are the same you really shouldn't feel any difference, or a very small one if any.

It does raise compression. I am playing with jetting now (its running a little lean right now).

I'm also guessing it has a smaller squish and higher comp. Higher comp makes you run hotter also, but i imagine the dg has better cooling with it.

It raises compression but also makes the bike run cooler. As soon as i get my seat pan prepped she will be on.

Nice, did you get that off ebay? One went pretty cheap last week. I was going to buy it, but I had no need for it. P.S. let me know if you need anything for your 250r. I have a complete one, minus seat and engine.

Sweet thanks. The only thing i am still looking for is a swing arm skid plate. I got the seat pan in parts lot that i payed like $65 for. It had some surface rust but nothing major.

Definitely a good buy on the seat pan. Those things are extinct! I will look when I get home to see if I have a skid plate.

That would be sweet. I have lucked out with parts for my bike so far.

hey- glad to see you got it mounted!!!! those fins clear eaisy??? didnt have to shave em like on my bike- i had fitted that head once and really liked the way it tapered for the pipe to clear- little different than my others.

BUT yeah i strongly suggest running 50/50 race gas! That DG head was unmilled and had a killer clean dome- puts a 148 psi bike to 185psi. and thats good enough for some real gas. hehe but with the head AND the race gas i didnt have to do any jetting... which the race gas is a tiny bit more rich cuz it burns longer.

AND yeah the first thing i found was when i went down my driveway in 2nd and turned around i could really stab it to spin it around... befor had to give a little "brap brap braaaaaaaa" NOW its jut "BARRRRAAAAPPPPP!!!"

It cleared no problem.I did need to do some jetting. I found you could hear it at idle. I found it makes the bike stall a bit easier now on real tight trails but it it's worth the trade off. I thought the bike spun before but it really does now. When i get the reeds i also have a carb and intake off of an 86 250R to put on.
