you dont want to punch your raptor over to a 727 its way to big, it requires extensive case maching, i know where you can get as much horse power as a 727 with a 20cc overbore.

You will not have much reliability in a 727. And its very pricey, with many things to do, you must be very experienced with engine work to maintain one of those.

Why do uneducated people make comments on things? It blows my mind. 727's are reliable, if done right. But they are expensive to build...most people don't want to spend that kind of money. They cut corners and boom...and suddenly 727's are unreliable. Know what you are talking about before you make posts.

Craycrafts 727, 740's are very reliable when set up the right way. There is some machining of the cases for the larger sleeve. Mine goes up to 9200rpm very easily and pulls harder than any 686 I have ever ridden.

I didnt explain myself right. I told him you must be experienced with engine work to maintain one. If you can mantain one, you have just the same ol bike. If your a new timer and putting one together, somethings gonna go wrong and they dont even know what to do. Your perfectly right, they can be very reliable if setup right.

Just because a YFZ handed you your *** DieScarred, don't assume you know about Raptors.

If you don't have the $$ to be the fastest, a big bore Raptor isn't for you. My Craycraft 686 was "stupid fast" according to my ex riding buddies. They don't ride any more, they got tired of being 2nd fastest. Now, they are drooling to test their nerves against my new Craycraft high-rpm 730. You think that little YFZ has a mid-upper RPM power hit?? BWAHAHAHA!

Im confused, why are you pouncing on me all of a sudden? I didnt even mention a 450 in this topic, and im not getting one cause of that reason. I ride track, and im young, I dont have the money too buy all the stuff for the Raptor, so can you lay off? Or atleast tell me what false info I put in here. I don't even see me mentioning a 450 in this topic.

Trust me, I would love to keep my Raptor too, if I could even dump anywhere to the amount of money I needed too.
