I thought you were kidding. XCR 800 jugs and HTG 180 kit would be the way to go but you don't have valves so you will need all of those parts as well.

You won't ever be able to push 200 ponies out of a 98 XCR 700. Plus, 200HP is too much for trail riding. the only thing it would be useful for is racing, in which case it would be much cheaper to buy a race-modded motor than to build one. If money is an issue, then building up a motor shouldn't be your priority.

you complain about spending 5 grand on a big bore kit, and then want to race someone who has 280.

you can turbo the sled and make huge hp or go to a big bore. bottom line is that if you are going to worry about spending 5 grand then 200+ hp is not in your future.

if you spend a lot of time shopping around you can build a water craft for about 2-3 grand and then buy new pipes.

only problem is when you get over 220 hp you are looking for a primary clutch that costs around 2 grand. sure hate to spend a pile of cash on a big bore only to wreck it with a cheap old polaris clutch.

before you start spending tens of thousand dollars on a custom race motor, you might want to make sure you can keep a basic trail motor running. By the way, you don't put 800 Liberty jugs on the 1200 PWC motor. You use 800 storm cylinders. Always do your homework if you want to get the good grade [AKA do the research so you don't f*ck up]

storm cylinders? never heard of that set up, i have tons of them laying around. all the 1200s i seen were 800 twin jugs.
if you plan on 400hp, you better plan on a heck of a chassis. asphalt is an art to race, chassis and suspension set up is very important, as well as gearing and clutching. it takes alot more then someoen with a hi HP motor to turn good numbers. as someone said before, better work on keeping a trail motor together, before running with the big dogs.
just race bracket class, its all about consistency there not top MPH.

Don't be giving people false info now...

You DO USE 800 big block twin cylinders, pistons and cranks to with the 1200WC cases. The cases need to be machined to accept the taller 800 piston skirts though.


as far as 400hp.....it's gonna take a hell of a lot of work to get a 1200 N/A engine to produce 400HP. The best race ported, race gas only 1200's make around 300HP. So you're goign to need to go a little bigger to reach your mark. You're probably goign to have to use 2 1/2 big bore kits and get a custom head made. I know Power Addiction Racing makes 1500cc WC based engines that should be able to make the HP you're looking for.
