Pull the heads and inspect the mating areas closely for defects. If there are none, make sure that you're torquing the head down to spec. If all else fails, get your stock head rechambered by Brandon at Mull. Stock type head gaskets are much more reliable, plus you will get a dome custom cut to your bike. GL

I say go for the cheetah. Tons of bottom end grunt that blends seamlessly into that top end rush. WAY more enjoyable to ride and much less tiring than the cub.

LOL. Did you really do all that? Did you notice a good bump in performance?

Dude you're more interested in putting me down than anything else. I bet you can hardly sleep at night huh. Give it a break my friend. That engine rick built IS made for all bottom end. He has 700 X the experience you have building engines. I would love for you two to discuss it formaly. Perhaps I can arrange a meeting. Even you said you ran a head cut .030", when daj said it would destroy the engine, but you could care less about attacking him. All I am saying is that if you are going o stick with pump gas cut your head .025-.030". If you want a better setup get custom domes or let Brandon mill your head for cheaper. Most people do not need a cool head plain and simple. You just can't stand to see me win. It is pathetic. Like a little girl.

Makes sense to me. I think it is safe to say that an off the shelf cool head dome isn't going to be a significant increase in performance over the stock milled head. Nor will the cooling properties be significantly better. If you want something significantly better than the stock milled head you need domes custom cut to your app. So we have about 80% of the voters that say the cool head is worth it, compared to probably 10% in real life who really truthfully could benifit from one. But I'm the brainwashed one

Harness, voltage reg, cdi. Everything but the stator, lights ect

Round plug

Please give us the specs of the motor you are talking about.

A cool head on pump gas will get you roughly 3-5 horsepower. So will a stock milled head. It's not difficult to understand.

I believe you are being overly conservative, but that is just my opinion. I think that .025" would be a good safe conservative number. But I hate to argue over .005" so let's just agree to disagree.

I didn't say they were not more efficient. I said the difference would be in-perceivable in a real world scenario. Definately not worth an extra 1-200 dollars.

You just Disagreed with yourself. I think a stock milled head approx .025" to .030will give you essentially the same gains as running a cool head. if someone is rechambering to your particular engine, rpm ceiling ect then you might get a noticeable gain from having the domes CUSTOM milled. I will agree with you there.

No sir. That engine is set up for a max of 8000

Nooooo I didn't say to just chop off .035. I said you can bring your squish down to .035" if you know what you are doing. Although people HAVE lopped off .035" before, with no ill effects. No piston to head contact for sure.Maybe you forgot to put the base gasket on? Ricks file that I uploaded is set up for .033" squish. it has also been rechambered but that has nothing to do with piston to head contact.

I'll buy that. I just don't believe that on a pump gas setup that the difference will be significant enough to warrant spending money on a cool head.

Sorry bro I sold it last night.

Hmm?

It's the non-crossover type intakes and havle a faux carbon fiber overlay. I will include a plethora of jets

From what I gather from that file, you are at the safe limit on 90 octane.15 to 30. It is at 30.7, which is juuuuust beyong the absolute safe limit. At 90 octane. Rick has been fooling with this software for years and years. I have complete faith in his word. If he says .035" is fine, .030" on a tight engine I believe him. Like I said, people go down to .038" on the stock head all the time and never have problems.

Seriously this is the first I hear of having problems from milling more than .025". Contact namely. I mean, you were in high school. You had high schoolers milling your head. Do you think that perhaps a mistake was made somewhere. You say the ring hit the head? The ring should be no less than .100" from the head at tdc. How did the ring hit the head? Something was out of wack.

If I don't answer your questions it is because I have you on ignore from being a hemroid. It's time to chill. The reason I said uccr is what dictates octane, it because I was trying to get the fact across that cranking compression is almost useless in determining what type of fuel to run. He is making it sound like the only reason he didnt deto with that much milling, is the fact that his exhaust port height knocked his compression enough to warrant pump. Whenin fact he could be running 220 degrees of exhaust duration and still deto, even though his cranking compression is only 120. UCCR is the dominant factor in determining octane requirements. If you are on the edge, compensate with fuel/ timing.

I love you too. Answer me one thing though. Where is YOUR extensive research and proof that states why .035" squish will instantly destroy your engine?

Some believe .040" is a safe number, some believe .035". I've even heard of .030" on a banshee engine. From what I gather, banshees are just tighter engines than most. On a 250R for instance, I believe .040" is around the absolute minimum. Banshee it is .030". Basically everyone that has milled their head .030", has knocked their squish down to around .038", and I have never heard of any engine destruction. And I know for sure at least one of them had an aggressive port job. I tend to agree with most of what you said though, and I appreciate your civil approach. Stock or ported other than full drag pump gas shave .025" - .030". If it were me I'd go .025" at my elevation Mildly ported race fuel or methanol rechamber or cool head. Drag ported racefuel or methanol rechambered head or cool head. Which still goes back to what I've said from the get go. I believe that less than 20% of banshee owners will ever NEED a cool head.

His port job only aaffected his cranking compression, not his uccr. uccr dictates octane requirements. I said to be on the safe side 50/50 should be used at that level. It appears though that premium is probably fine in most cased. I stand corrected on that. And the fact that mccain lost doesnt speak as much of him, as it does of the ignorance of the voters. Kind of like this poll.

Apparently you are just looking for ANYTHING to attack. You see some red writing on a graph that you really don't know squat about, and you try to attack it. You're acting like a girl. Rick is the most conservative builder I know and he would never do something to a customers engine that would cause him to doubt it reliability for one second.
