What ever boat that had the taper bored 38s on it

Im sure you can get them to go ok but your never going to get them to go as well as a 62t set of cases with getting rid of that sharp 180 degree bend. Every time air has to change direction more than 15 degrees it loses momentum. this is why much time is spent on 62t cases with ramps and porting...

Dont use the x-cases the reed choices for them are limited at the very best they dont flow racers used to cut off the intake and change it to the 62t style so they could get power out of them. The Yamaha engine went from 63 hp to 73 when they changed it to the 62t case design. The only time you...

I just bolted an x-metal 865 engine together for some one in Australia. To the guys at x-scream well done on a excellent kit. every thing just bolted together the way it should, almost unheard of these days. I port a lot of my cylinders and cases for people over here but some times they...

Ha ha ha Was he to pissed to ride after that, I have made a b-pipe 3 bolt gasket from a beer box one time on the beach. Was still going last I heard

Jb weld would break up under the load If you really wanted to use the head and im not sure why you wouldn't just buy a new shell ? you could possibly machine the head then make a shim to get the heights right. But better still buy a new head

I agree with you. The amount of rubbish sold on the market here is insane. I have seen hoods and hulls etc that are sold as carbon but are just fibreglass There is so much stuff that doesnt fit when you bolt it on I have seen intake manifolds that have bolts to long so things are held up and...

opps, how did you go putting it on. They do go on but its not an easy fit. last one i saw had done some damage from them wrestling it on

The head is not able to be rotated. The two bolts on each end of the head are not symetrical. watty brings up a good point and its an easy check. Some times engine builder look to hard and miss the real easy stuff

There is a lip in there and the sleeves seat on it . The cylinder head holds the sleeves in place as the engine is running. You can heat the cylinder up and remove the sleeves so it makes sense that when the engine is running the sleeves could actually come out or at least move. If you have a...

I have never seen a sleeve drop in one spot and I cant imagine how it would. have you used a straight edge on the top of the cylinder to check it

The o-ring seals on the sleeve so the gap while it doenst look good is not an issue unless its sitting higher then the sleeve.

I find all or at least most 61x cylinders will settle there sleeves. Im not sure if the sleeves isnt home from the factory or if the cylinders move a little. Its not normal that they continue to drop as your are doing. I did have a cylinder do that before and after it had be machined twice I...

I would never run a mod on a customers boat out of choice. If they come to me with that then I will run it. the power is much more abrupt in the surf and it doesn't respond to small throttle inputs like a limited I would have though fp would stop selling the mod before the limited

Im pretty sure most people on here are boycotting his product already

Yup your ski engine is like a station wagon it does a reasonable job of everything. I can build those any day of the week I thought the question is what is the best aftermarket engine out there. And to answer this I want to know for what type of riding.

Well not really, if you told me you wanted to race your mates across the lake then I would change the port timing to make it rev on harder. If you said you wanted a flat water back-flip boat I would change the exhaust port shape to make it smack on harder, but dont rev the crap out of it for...

people underestimate what a 701 can deliver. Most of my engines I build are also 701 -710 cc. setup right they go very hard. Its alot of money for the extra 100cc some times and when the pistons opens by at best 50% bore travel get your added cc and divide it by 2 I will be staying with the...

What do you want your engine for. Is it a surf engine, are you trying to flat water back flip, are you trying to blast past your mates on the lake with top speed

hahaha Thats the best post in this thread
