BigRed350x Posted December 14, 2009 Report Share Posted December 14, 2009 (edited) CP Industries cylinders and twister billet cylinders all utilize a tripple exhaust ports and different intake designs. They also use boost ports between the intake and transfers. For a comparison, here is a set of stock cylinders. You can see the difference in the cooling design differences between a small-block twister and stockers.

wizeass2005 Posted December 15, 2009 Author Report Share Posted December 15, 2009 It is kinda rude that the guys first post with a legitimate question gets told to google it and search. He asked for help and I'm sure there is some people here that are more then happy to help him out. Its not like he asked about a boost bottle. By the way.. I looked through that link and there was absolutely nothing in there that pertained to his question.... Hey I just want to thank you all for your help. Now I know a little more, I had never even heard of cp industries. I was wondering can you still dune a big bore bike like a 611 or are those pretty much just for drag. how about the reliability of a big bike. And I did do a google search and it brought up nothing usefull. Quote Link to comment Share on other sites More sharing options...

And I did do a google search and it brought up nothing usefull. A 611 (16 mil Cheetah) would be a handful as a duner that's for sure. Your talking ~ 150 hp. Note that you would almost never want to put that engine in a stock chassis. Throw a 4 mil Cub (421 cc) or a 4mil Cheetah powervalve in a stock chassis with upgraded suspension, swingarm, etc and you would have a perfect duner/hill shooter. If you look around you can find complete Cub engines for sale that already have an override transmission and lockup in them that would be pretty much bolt-on and go.

There are a lot of combinations out there that could get you into the 600+cc range and not all of them involve a huge stroke. My 612 is a 10mil stroke and you could definitely dune it if you can handle a bike like that, and had the right suspension and frame setup. You dont want a full override in a dune bike. WCR makes a duneable override and a new extreme model. Both would work for a dune setup. a 10mil cub makes a pretty mean dune bike, but a 4mil cheetah is plenty for what most people would do in the dunes.

OK cause i was thinking of the same setup that you are running, a 78mm bore with a +10mm stroke. are you on stock casses? It would be a lot cheaper to do a 421cc but most people I ride with have those I wanna leed the pack for once!!! haha Quote Link to comment Share on other sites More sharing options...

You'll also need all new inakes, reed cages, head and exhaust pipes as nothing from a stock banshee motor will bolt on. I dont know what your expectations are for reliability but.. with a motor this size.. its not a matter if stuff will break, Its a matter of when. They tend to find the weak links rather quickly and often. Quote Link to comment Share on other sites More sharing options...
SonOfSand Posted December 17, 2009 Report Share Posted December 17, 2009 This is great info guys, all stuff I was wondering about as well, but could never find the maker of the cheetah cylinders. Who makes the Twister, and what is the website? Thanks to everyone! Quote Link to comment Share on other sites More sharing options...

What's the fastest/most powerful fourwheeler that you've ridden? If your gettin' off of a stockish Banshee and then onto a 600+cc Banshee please be careful. Even a good running alky 421 will make a piped Banshee feel like a tricycle going backwards. The 421 is a good "entry level" build as well as the most bang for your buck. Once your comfortable riding that you could always sell it and upgrade. Just a thought. Quote Link to comment Share on other sites More sharing options...

The 421 is a good "entry level" build as well as the most bang for your buck. Once your comfortable riding that you could always sell it and upgrade. Just a thought. Pretty good advice there to be honest. But if you insist on a bigger motor like a twister, DM or DMX ect. you're going to have a lot of work done to fit the crank/cylinders in your stock cases. They will need welded/epoxied, trenched and bored...some cylinders will require adding to the case deck as well. Mattoon Machine makes billet cases to fit the popular cylinders and big strokes right out of the box. When you build and engine of this calibur it's a package purchase...not really something you can add to here and there and ride in between. In other words your stock motor bolt ons don't fit and you're going to want to just get the transmission built with billet second and the billet basket with straight cuts right off the bat. Build it right the first time and try to avoid costly breakage. Quote Link to comment Share on other sites More sharing options...
