twinrock Posted January 16, 2007 Report Posted January 16, 2007 im lookin at a up grading engine..i was wondering if a vito404 kit would make more /same/less performance then a rz350 conversion as well as a cub 392 thank u.. Quote
LiftdT4R Posted January 16, 2007 Report Posted January 16, 2007 What were you looking to do with the bike? The cub is basically a drag engine, while a lot of MXers go with the RZ engine, it has a smoother powerband, the 404 I'm not familiar with, so maybe someone will chime in about that kit. Quote

As far as Ive seen, the 404 is a JOKE!! I smoked a 404 with DMC 916s, with my stock jugs, .100 over, non ported with FMFs. Somethings not right there. This 404 was dialed in too. It ran good, but id stick with porting your stock cylinders!! Quote
dajogejr Posted January 16, 2007 Report Posted January 16, 2007 For drag racing... A cub will flat out smoke a 404 setup. A 404 can be made to run very well with a lot of porting, but...what's the point? A cleaned up cub will wreck that motor in a drag race. Here's something for you to think about. If you go RZ...are you prepared to deal with all the electrical headaches due to the power valve system? Cub...this is a drag race/dune motor...which you bolt on, then get a longer swingarm, upgraded clutch, etc. It's an all top end motor, that responds best to large carbs and open, free flowing drag style pipes. How fast do you want to go, how much you got to spend? In reality, a lot of guys want an aftermarket cylinder, when a good port job from a reputable builder is cheaper and all they really need....

Big Mike NY Posted January 16, 2007 Report Posted January 16, 2007 DAMN dajogejr! You sound like you really know your shit! I enjoy reading and learining from your posts! :thumbsup: Quote
dajogejr Posted January 17, 2007 Report Posted January 17, 2007 DAMN dajogejr! You sound like you really know your shit! I enjoy reading and learining from your posts! :thumbsup: Thanks...I research a lot, and made very good friends with someone who has seen just about every combo come through a dyno, back to back...day in and day out. I've also absorbed a ton of info from this site and others, and by speaking to a lot of good folks and fellow riders at the drag strip and at the dunes... I couldn't even begin to name all those who've helped me and who I've learned from!!! Glad you enjoy! Quote
LiftdT4R Posted January 17, 2007 Report Posted January 17, 2007 If you go RZ...are you prepared to deal with all the electrical headaches due to the power valve system? The RZ has a lot of electrical components to it. I looked into doing one on my bike, but with the cost and all, it does get up there, I decided to go with an MX port instead. On the RZ you also need intake flange adapters, the banshee has a spigot setup, where the springs hold the headers to the bike, where as on an RZ, a flange(like on a 4 stroke) holds the header to the bike. It's not a big deal, but you will have to make an adapter, or have someone else make you one. Also, only certain pipes will work on an RZ, because the powervalves get in the way. You will need either PT mids or high revs, or older Rocket Pipes. The elctrical is a bit tricky too, check out the parts microfiche for an 85 RZ350, the wiring harness has a TON of wires, most of which you won;t use. The powervalves also run on DC, so you will have to either rig up a battery or a rectifier, and you have to make a special place to mount up the servo on the bike. Like I said, I don't know much about the other 2 setups, but from what I hear, the 404 does suck, and I know Daj is almost always on spot with his knowledge! If your just starting out, I'd say stick with a port job first, and you could always upgrade in the future. I still want to do a RZ engine, but I don;t ride enough to justify it, and an MX port kicks some serious ass and is alot cheaper. There is also a ton of good info on here, and I would check that otu as well, the search is quite useful! There are also a few people on here that have done the RZ conversion. Quote
twinrock Posted January 17, 2007 Author Report Posted January 17, 2007 hey guys thanks alot..i really love this forum..its good to get the opinions from ppl who have bought owned and run the stuff..not just trying to sell it to me..its also had to find any good testimonials here in oz. i think i will go with a bace cub.thanks again Quote
majicmike Posted January 17, 2007 Report Posted January 17, 2007 hey guys thanks alot..i really love this forum..its good to get the opinions from ppl who have bought owned and run the stuff..not just trying to sell it to me..its also had to find any good testimonials here in oz. i think i will go with a bace cub.thanks again Just so you know I would not go with the 68mm stock stroke cub. The ports are better suited on the 65mm bore and here is the kicker you will save money cuz the pistons are pricey compared to the 65mm stock stroke and the other strokes. IMO you would never feel the differance Quote
twinrock Posted January 17, 2007 Author Report Posted January 17, 2007 ok who would be the best ppl to order one from..remembering im in australia..and let me get this straight 65mm bore standard crank? bolt on? Quote
dajogejr Posted January 17, 2007 Report Posted January 17, 2007 If you're going cub, I think you need to have your stock crank at least trued and welded. Other than that....yes, it's pretty much a bolt on. You need to be very careful, however...and check your squish to make sure it's proper on any new build. Mike, I don't know if you can get cubs or will ship to australia....didn't want to speak for you.. I'd bet Jeff @ FAST can get you what you need, if Mike can't....shipping might be a bugger, though.

Meat Posted January 31, 2007 Report Posted January 31, 2007 I have both motors, an stock RZ350 with a set of pipes and a Vito's 404(392cc) with porting, pipes, Nosshead and V-Force reeds. The Rz350 motor is run in my streetbike and the 404 motor is in my Banshee. The 404 KILLS the Rz350. The power on the rz is smooth and the gearing is meant for more top speed, but the power delevery is alot more fun with the 404 motor. As far as the guy sayin' the 404 is a joke, I'd like to know if you own one of these motors ?? Ya got any first hand experience wit em .... meaning, have you run a 404 motor for any length of time, like a years worth of riding with a 404 motor, or is your experience wit em, watchin some guy drag race, reading info on the forums or perhaps a quick spin on sum dudes 404 one time ?? Saying the 404 setup is joke is a completly wrong statement. My 404 is super reliable, very strong in the mid range and overall runs pretty damn good. If the motor is going to be used for drag racing, there are better setups out there, but calling the 404 motor a "joke" .... I have to disagree. Wanna see some videos' of a ported 404 beaing 4mm strokers ?? Def not a joke. Not everyone needs or wants a motor that gets ya to 300 feet the fastest. Quote
dajogejr Posted January 31, 2007 Report Posted January 31, 2007 Meat... Let me clarify... I've seen a worked over 404 motor, meaning it was ported and had a good overall package done to it. That being said, my 421 spanked it in a 300ft drag, he had a lockup and override...I had a stock clutch and stock tranny. My experience against a 404 was strictly drag, strictly 300ft. That is why my post starts out: "For Drag Racing" I have absolutely NO DOUBT is it a better all around motor for duning, trails, etc. It has to be...a cub is pretty much a top end, dune and drag motor...it doesn't take much to make an all around better motor than a cub. A good set of ported stock cylinders setup properly is a better "all around" motor no doubt...and a blast to ride. So...that being said, my specific statements of a 404 Vito's vs a cub being a joke stands true in the drag racing perspective only, as I wrote. I don't' think I misrepresented anything incorrectly in my statement, and it was out of 100% experience... :beer: Quote

I said it was a joke because my worn out .100 over cylinders walked all over it. I wasnt too impressed. That being said, I believe a strong port on stock cyls is a WAY better path. Its far cheaper,and easier to deal with IMO. Thats sweet that youre super happy with the 404, im sure I would be too if I had one dialed in and tearin ass. Maybe the ones Ive ran into are not built correctly, or the rider is a a sorry SOB. Quote
