LC's in RZ Cup
How strict are the rules in RZ cup regarding mods from stock on an 81 LC? I mean can the engine be modified to be competitive with later models so long as it stays under 60hp? With the LC cranks and cylinders getting ever more espensive my thinking is that a Banshee engine is the way to go as parts are plentiful and cranks are so cheap rebuilding isn't even an option. I suppose with a stock Banshee making about the same hp as a stock LC you could go that route but do the rules allow for a bit more to close the gap with later model RZ's?
Also does it need to keep all the stock bits (other than those normally removed for racing) or can it be stripped down to the bare essentials? ie: no battery, charging system, switches, and other unnecessary bits.
We will do our best to accomidate pretty much any group that wishes to race but there haven't been nearly as many RZ's as there were last year. I think that we're down to three competitors and at least one of them is a very far from Cup spec RZ. They are all racing Open Twins and Formula 2 at the moment and are fairly competitive.
OK so they way I ready it:
Appearance: so long as the bike looks stock, unnecessary bits such as speedo, handlebar switches, main wire harness, battery, and battery box, oil tank, radiator covers, grab rail, etc can be removed......correct? Regarding addition of fairings, what about OEM accessory bar mounted fairings (which "could have been purchased installed" with a new bike) or fibreglass copies of such fairings. Like this:
Performance: aftermarket pipes are allowed, engine modifications (or the supstitution of a Banshee engine) are allowed so long as the hp does not exceed 65 and the you don't exceed stock overbore dimensions........correct?
Brakes: Pads and lines may change but can similar discs be substituted if stock ones are worn and other replacements (read cheap) are available such as those from the XJ series.....some of which are slotted? And can stock discs be drilled?
I don't know if there will be enough bikes to run the RZ cup but they do qualify for F3/F2 and I think BOTT.
There were only a couple of RZs out at the last race, both with 17" wheels so I don't think they would qualify for RZ cup.There are two RZs going out in the next race school so hopefully there will be a small pack of smokers racing later this year.
Get that bike race prepped and come on out!
Ya, I think the wheels would DQ them from cup class. I doubt I'd go that route as the goal is a budget racer, or as much as I'm capable of doing........I'm kind of fussy about doing things right so it's hard for me to NOT spend to much. I was thinking about trying mini-motard but I'm not sure you can run that class as a novice and I don't see myself spending a year on a 4S thunder bike to get there so I guess an LC is the way to go.
It wont be this year for me though as I still have my restoration project that has to take priorty and that will likely be well into the fall before its done. After that I've got three other LC frames and a crapload of parts so putting one together is no problem other than a crank and that is why I'm thinking Banshee. I took 2 cranks and a third that with a bad pin in for them to use as parts and told them to use the best one and I only ended up with one crank out of it, the rest all had pitted journals. A new LC crank is about $950+ whereas a new Banshee crank is less than $400 its pretty much a no brainer which is a better choice in a race bike.
With Banshee engines being easy to find and one in need of rebuild being fairly cheap and easy to find and the fact that they bolt right in, they are the perfect replacement and no silly valves in them. You think there just isn't enough interest in 2 strokes to make a cup class a regular deal?
I'd love to see a bunch of LCs and RZs out there but I guess only a few people (read mostly older) see them as realistic race bikes. Most of the new racers out there are on newer 600s. I've only been back around the track this year and haven't been able to make the time to get out there but I'm gonna force myself to get it ready at the expence of pissing off some customers and my wife!
My RZ has a banshee crank, spec II pipes and a bunch of other stuff including no battery so I don't know if it would qualify for the RZ cup either. I would like to go with the 17" wheels for next year but thats getting ahead of myself.
I'm supposed to be working on the bike now but I'm too freakin' tired after plastering a pool in this heat.
Hope to see you out there and yes, we have no Ardons.
Tony & P51 - check out the rules link that I sent you on this post.
I sort of spearheaded getting the RZ Cup back into the rule book for last year & there was about 5 stock RZ's that had committed to racing... there were also some highly modded bikes out there that didn't qualify. Before the RZ Cup was set up I did some polling and found out that there were quite a few racers who were interested in racing these strokers. I have since sold mine (David is taking the race school in July) and one of our avid racers had a mind fart and moved to Calgary (right Blaine?) but other than that there are still a few of "us" out there (can I still be part of the club?).
I hope to see you BOTH out there in August.
So how come you sold the RZ? Looked like a pretty nice ride, although I think I'd rather have something with less plastic......cheaper to crash Plus I'll always be partial to the LC as it was my first streetbike. (new in 81) I did have a read through the rules and as I read it there is a bit of latitude as far as engine mods (at least on an LC) so long as one doesn't exceed 65hp and you would have to get a bit radical with an LC to do that. Again my thinking is Banshee engine with some light porting mostly due to availability and cost of replacement parts. Although I have a fair number of LC spares I want to save them for my restoration project as I don't ever plan on selling it. As of yet no one has contradicted my understanding of the rules. What are your thought's on the use of OEM accessory fairings......legal or no? Of course I'm biased but I feel that a factory option should be allowed.
