No, but the chance is worth it when you dont have $200 to spend. I'll say it now, I'm not a barrel-rolling backflipping surf maniac, so I dont think I'll crack it the way I ride (no flat landings etc.). Mabye I'll upgrade this summer, but I gotta start saving for college.

I will have to say it does cause some more abuse. But I dont see it as being enough to crack cylinders at all.

Well there is one of two reasons for why you guys havent cracked your cylinders or not worried about it....
1) dont ride hard
2) dont give a ********
When i build somehting, i build it right! Cutting corners ALWAYS costs more in long run.
And about the vibration thing....Why would that always cause the crack to appear in the same place? Vibration causes bolts to back out and engine mounts to break, it does not cause a fixed peice(cylinder) to crack.
Vibration will cause your mounts to break and if you have a peice of metal that holds a pipe (such as a dry pipe) to break. this is only due to the fact that it is being held in 2 places with rubber and in one place with metal. the metal can not support all that weight. The cylinder is in tottally different scenerio.

On yea,....Is that why it causes enough abuse to break hulls in half? of is that the vibration issue also?

Alrite, maybe not a clean in half break, but they deffinatly get to the point of unrideable. that is the reason people reenforce....

Wow. Breaking hulls from freestyle/ride riding style has nothing to do with cracking cylinders.
In light of all this 'be respectful' stuff flying around on here I have nothing left to say except believe what you want, I simply do not agree at all. I think we can leave it at that, so nobody's feelings get hurt and this doesnt turn into some lame argument thread that has happened all too often lately.

you could always go with a protec head. that way you can always add the girdled kit later on.

You could do that, but isn that about the same amount as a used nice girdled head. girdled head sonly run about 250 used.... The protec one is cast right? I love the look of a chunck of billet sitting on top of the engine:Banane01:

OEM cylinders have sh** castings. Look under the cylinder on the mounting surface......hollow cavities put there to save $$ on materials. That also decreases cylinder strength. Girdled heads are functional b/c they spread the load across the top and bottom of the cylinder as opposed to having that load fixed at the base.....the hollowed out base. No need for a girdled head on a lamey cylinder b/c the casting is solid=strong and the material used is of better quality.
Girdled head was designed specifically to combat the OEM cylinder cracking issue. It is also a good idea to use a girdled head if you use a pipe that is attached to the head as that can put further stress on the base of the cylinder.

I told you, I have nothing left to say for the sake of not arguing and having respect for people who moderate this and dont want to babysit.

Luke is doing the same that you are, voicing his opinion........ Please respect that...........
You are both right.........
But as a racer I can tell you that more cylinders get cracked from running higher RPM's........ Harmonics (Vibration) can find the week points and cause cracks............ Right front corner of the cylinders..... week point on all 61X's.... But most cracks come from built motors, especially motors designed for higher RPM's.
With that said, I prefer a Girdled head for all applications unless it is bone stock.
Been running the same cylinder since 99, Rec ride, Raced and Freestyle.......

Sure, But he is telling people that if they stay low RPMs they will not crack a cylinder, that is NOT and i repeate NOTTT true!

I understood exactly what he was saying....
A motor that only does say 6000 RPM has less chance of cracking than a motor that is running 7500 rpms....... Less strain on the lessor powered motor.
But that is beside the point. he has his opinion you have yours.........

Riverat is correct - the OEM castings all have flaws - you maybe lucky, but you may not.
I was NOT - it cost me big $$$ - I ran a Riva non girdled head at 185PSI and it lasted a couple of months and then the top cracked clean of the cylinders while I was doing a bull dog of all things :bigeyes:
Imagine the cost of replacing a ported cylinder just cause you scrimped on a simple girdle kit... I kicked my own azz for a few weeks after that mistake.. I was warned by several people not to run un-girdled and I ignored them to my cost..
Here's my setup now (with ADA Girdle)
