What exactly do you get for $5000. Do you have a price breakdown? Thanks!

You don't want to wrap aluminum with carbon. Corrosion can be a big problem. Also the x metal pole weighs almost double what the XFT weighs. Hmmmmm.......better knock on wood for sure!!!:haha:

The headpipe starts as the same part for both. The flange that mates to the manifold is thicker on the Kawasaki. The Yamaha is cut thinner. Otherwise they are identical.

Quick update! Got my chinpad the other day and all is well. Sergio is the man!:biggthumpup:

They're brass, but they're pressed in also.:cool:

The new ski is a much better value for the dollar than the other one he's selling.

Chic.

That help?:scratchchin:

Timeserts work fine when they are installed properly. Helicoils are easier to install properly and also work very well. An added benefit to helicoils is that they are easily removeable if there is a problem. I got a 760 cylinder from a popular builder on this site a couple of years ago that he...

I agree too. My white boat you rode at Lanier was heavily reinforced before I decided that I don't ride hard enough to need all I put in it. It weighs a ton.

Who is mark? If you are saying talk to mark, it would help to say who you mean.:thinking: Erikson, Matsuda, mark44, jeepmark,etc?

Since I am one of the people who have built a carbon chamber I'll say what I know about the issue. First, it's anything but easy to make and have it look presentable. The "test results" from the link that Tricky provided are to be almost entirely disregarded. We all know now there was never any...

All of this is true!

I think you can have most of the best of both worlds. There's no reason a well setup "freestyle" motor can't run in the mid to upper 50's depending on prop/nozzle combo. That's not really that fast. A well set up motor can easily turn mid 7200-7500 RPM with a B pipe. A good bit of the powerband...

I wouldn't worry about it at all at this point. A lot of "race" motors make better freestyle/freeride motors than those built as such. Most of the real info and tuning knowledge in this sport comes from guys who have built a million race boats. There is no proving ground or objective way to...

I agree with his thoughts. If a change from 50:1 to 40:1 or even 32:1 made a boat run noticeably different, I would say that you either have VERY finicky carbs or were tuned on the edge of lean anyway. I run 32:1 castor in all my stuff and the only other oils I would really even consider are...

Me too. I'm sure it will be a glowing report.

What??? That reads like a text message. Anyway, yes rod angle matters, but motors longer than 6mm NOT BEING ABLE TO BE RUN WIDE OPEN was what you posted. That's not an across the board fact. Plenty of 8mm motors run WOT all the time. Also, most builders like to run long rods on 6mm and...

Who told you that?:thinking: I guess Tricky and all the mod class racers didn't get the word.:scratchchin:

One other thing I thought about. Jetworks builds a 4mm motor on the OEM cylinder that runs better and harder than most 5mm and 6mm Lamey packages.:burnout:
