trickedcarbine Posted June 15, 2010 Report Share Posted June 15, 2010 Well, the big bore stockers are about on their last leg, and this means it's time to start looking in to aftermarket cylinders. The current set up is about 75 hp and used for circle track. Meaning the cub is out and a pv cheetah seems just a lil pricey. So after looking around i found that Rob at RDZ is producing a big bore cylinder that is ported to spec for each sale. We all know that any thing with even a RDZ sticker is a freakin runner, but i just havn't seen or heard any thing on these cylinders. Any body around here know any thing about this particular set up? Just lookin' for a faster alternative that will be proven. Quote Link to comment Share on other sites More sharing options...
87sheerips Posted June 18, 2010 Report Share Posted June 18, 2010 Well, after speaking with him in person yesterday about these.... He claims they are the cats ass... As good or has potential to be better than cheetah cub cyl's... I have no Idea personally, and of course he will rave about his own product.. But he does know his stuff and id take his word for it based on what Ive seen! Quote Link to comment Share on other sites More sharing options...
dajogejr Posted June 18, 2010 Report Share Posted June 18, 2010 He's taking the Chinese cylinders and putting his porting on them. At the end of the day, the question is how much work do you have to put in them to get them to run like a CP cylinder does out of the box? Of course Rob is going to say their better than the CP cylinders, he is no longer a dealer for CP because him and Calvin/CP have some kind of issue. There is a post about it in Resolution Center on Planet Sand. Calvin is basically saying he's pulled all support from RDZ, he is no longer a dealer and asked customers to buy from one of his other dealers in good standing. When Rob broke the record for 400cc this year, what cylinder was it on? Pretty sure it was a cub motor.... I know any new product, like these cylinders, need time to be developed. But CP cylinders have set the bar pretty high and that bar has been there for years. Quote Link to comment Share on other sites More sharing options...

Record was definitely broke with a CP cylinder and if I were to upgrade to a cylinder other than stock I would definately go CP. I just wanted to chime in about what Rob had to say about the Eliminator. Obviously that is a Bias opinion coming from the creator of the product, but its something to talk about nonetheless LOL...

trickedcarbine Posted June 18, 2010 Author Report Share Posted June 18, 2010 Well, when i called him saying i was looking for about 80-90 out of an ice/circle bike , he said these will do it. Didn't brag or any thing like that. I know he knows his shit, just wonderin if he is in tune with putting out different styles of power other then drag motors. What is his porting like, does he do any 12 port work? I know i heard that he even played with some exotic styles similar to grand river racing, but havn't really seen other bikes from him but big ol long draggers. Seems to me every shop has it's quirks, but it would be flat out awesome to find a Banshee specific builder here in michigan to really stand up and help put my bike up front and keep the support there if i keep spitting money at their wallet. Just tired of local builders leaving me hangin after they get the cash. It's a busy world. But i don't make alot of money, but this industry has a shit load of my money.

Call Rob at RB racing, he races (or did) circle track... he ported my duner 350 shee and it scoots damn good. RB Racing : 517-388-3662 See what he says... usually has great turn around time, and he is right up by Lansing. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted June 18, 2010 Report Share Posted June 18, 2010 If you are specifically looking for a local MI builder, R&B is a good choice. As is Mike @ Lakes Motorsports in Waterford. Otherwise, talk to Kevin @ HJR, Jeff @ FAST, Andy @ M&M or Jim @ Passion. All site sponsors, quality builders, etc. I've never seen Rob do anything other than Drag Motors. He's got Stages 1-4 porting on his site, but I never believed in that "Stage" stuff. I've always believed in the right port job and work per customer... I have to be honest...if you wanted 70ish out of a set of stockers for duner type motor, no problem. 80 to 90 is kind of pushing it on stock bore/stock stroke unless you're looking for an all out drag port (narrow, high RPM powerband) If you wanted to turn your motor into a 4 mil stroke, that might be a bit more obtainable. RDZ cylinders are cast like any drag motor is built, triple exhaust ports and worm holes/boyseen ports, whatever you want to call them.

trickedcarbine Posted June 21, 2010 Author Report Share Posted June 21, 2010 Thanks daj & jd. The current motor is a 75ish h.p. 4 mill with big bore sleeves. The porting is done by mike at lakes motorsports. They are good people over there. In fact i just rode all weekend at ogemaw with him this weekend and had a blast. Well.... I guess the real question would be, after looking at those rdz cylinders, does they even look like they would be a decent set up pn the ice or flat track. He claims he would port for my style, but like daj said, he seems to be on the trinity path as well with the cookie cutter stage porting. I want some thing faster then the stockers with a 4 mill. Just seems like a cheetah is the only other viable option. The cub just wont produce the low end i want. Any one out there you know of enhancing the cheetah ports for my type pf riding? The folks at tss in austrailia run them on road bike courses with success. But there are some really neat tricks goin into them. Quote Link to comment Share on other sites More sharing options...
hercalmighty Posted June 21, 2010 Report Share Posted June 21, 2010 Ok. Are you talking about a cheetah motor or a cub? The tss guys are using the pv cheetah motors in their street bikes. If you want a motor with bottom and top get a pv cheetah. The cubs are pretty much a mid to top setup. They do have bottom but because the mid to top is so great it seems like they don't have bottom.

trickedcarbine Posted June 21, 2010 Author Report Share Posted June 21, 2010 (edited) Not sure what you're askin hercal, but if it is in referance to the tss motor, yea the cheetah. T he cheetah and cubs are about the same except the cub is with out the pv's. The trick thing the tss guys do is use a programable cdi unit that not only does the ignition but has a progamable pv servo controller built in. Compare that to the spring pressure controlled pv that a cheetah would normally come with. Pretty trick, because it allows you to fine tune the pv action for your specific needs.(porting,jetting, traction etc.) Edited June 21, 2010 by trickedcarbine Quote Link to comment Share on other sites More sharing options...
hercalmighty Posted June 21, 2010 Report Share Posted June 21, 2010 (edited) Yeah. I have been checking their stuff out for awhile now. You were talking about both a cheetah and a cub so I was wondering which one you wanted. --- Ok, i just reread your post. I confused myself, lol. With a PV cheetah you really wouldnt need more then a clean up for the racing you do. They really have a great broad powerband for a 2stroke.

trickedcarbine Posted June 21, 2010 Author Report Share Posted June 21, 2010 Well i woule love to run a cheetah with the hybrid servo controller for the pv's in it, but was lookin for viable options for my specific needs. Other wise it'll just be another set of stockers with a 12 port from jim at passion. I would just prefer to venture out and pioneer something different. Hence my wondering about the abilities of the rdz cylinders for my application. Quote Link to comment Share on other sites More sharing options...

trickedcarbine Posted June 23, 2010 Author Report Share Posted June 23, 2010 Well, i must say i am surprised at your post Rob. From what people try to portray you as, i expected a super arrogant jaggoff with a smart mouth, just looking for a crazy argument over this. You seem humble yet confident in what you say. I like that. Just looking for a little assurance that a set of your cylinders would be a wise choice for my set up. With the 4 mil, can they push the 80/90 range on race gas, and still have a decent bottom end to pull out of the turns like a raped ape?
