19" Ice Tire - Gearing Suggestions??

So I ended up with a complete 19" rear wheel by mistake. The price was right so I kept it with the idea of putting an 18" rim on it

I am a regular on the ice and I remembered that it was easier to get 19" ice tires (since all the moto bike use them) than it was to get 18".

Perfect, I'll mount a 19" ice tire to it and never touch it again until I need a new tire (you need 5 men, 2 dogs, a blind exotic dancer and a goat to mount one these animals).

So what gearing do I use for the front & rear sprockets??

Thanks for your input.
 
That would depend on the length of the race track and traction conditions on the day would it not, sir Coffin?
What is a more important question ...what would it take for purse money to get every serious ice racer in Atlantic Canada together for one day to see who is the Atlantic champion?
 
NSMAN speak wisely coffin, and you should have known. ( my own version of Mr Know It All, except I don't. HA HA I was out with the Cornergrass boys and their 650 that they are going to endurance race this winter. They started with 15/48 and found it revved out to quick and overrevved as well. THey installed a 16 and found it worked better, but that maybe it would quite pull top gear in a few places once they shifted from 5th, so they installed a 50t with the short lug of the axle in front ( short chain adj bolts and the small end of the axle block ) A couple things observed. 1) lap times were no faster 2) the bike was more violent, more fun, but also more tiring, 3) they were spinning the tire, so tire longevity was a concern, and finally 4) the tire expanded enough that it chewed some of the inside of the swingarm away, as well as almost 1/4 of an inch of material away from the bottom of the shock. So they went back to 16/48. They ran 15/48 with my 550 last winter, and realize now they should have geared it up as well.

Really though, if you are doin roundy round, testing is the only way to see if it is over revving or lugging etc. Go buy some extra gas, some chaine wheels and take her for spin. And have a buddy do lap times for you as seat of the pants isn't always the way it should be run.

once again, you should have known!!!!

The tracks in NS are smaller than in NB I think.
On my 450 with 14x50 (I think) I'm in 4th all the way around but I'm not trying to win anything.
I'm just out to have fun and not kill the bike. I found 3-4 shifting didn't get me around any faster.

Sheesh...I just wanted to come visit and play and you guys have to start beating the war drums. :roll:

I'm not so sure there are very many serious ice racers around these parts yet nsman. I thought that was our mission...to develop them. Unless your talking about getting all the crusty old vets out from yesteryear like Lockhart senior, etc.

I say we focus on getting some young guns primed to go represent in Quebec and out west.

Good input Fry. I'm not keen on the carnage caused by that 50 tooth. I'll experiment with the 15/48, 16/48 combos.

Are you running the 24hr Numb Bum on the 650 with Jay & Nick?

Cheers

I have been quitely brain washing nsman in changing that and building you guys standard 600/700 foot tracks. Inside and outside tip to tip. I think you will enjoy the longer track more and will be happy to have the extra breathing room of a 50 foot wide oval.
 
RE: Re: RE: 19" Ice Tire - Gearing Suggestions??

You could use the 50t if you ran the longer chain, which may even work with the 48????? A guy would have to try it.

I wanted to run Numb Bumb, but they cancelled it. THe guy that has orgnanised it for the past X years could not get anyone to step up. D($)$*@!!!!

that 650 is dangerous and would have been cool to see if the competition could keep their 560 together.

Are you kidding me...the sky is falling...the sky is falling!!!

First I hear that the traditional ice racing scene at Port Perry in southern Ontario is toast due to insurance issues and organizational challenges...although I hear that George Jones is keeping some 2 way races going...and now they cancel the 24 NUMB BUM 8O 8O

Wow! That truly is shocking. I hope they can get people to step up and get it going again.

NO
A three hour would be a challenge Kelsow,just stop and think how long 24hrs actually is out on a lake in Feb. :D
 
RE: Re: RE: Re: RE: Re: RE: 19" Ice Tire - Gearing Sugg

Just think though. The Hatfields VS McCoys, City Folk VS Country Folk, Halifax VS Valley.
Have 4 members per team @ 1 hour stints.

Well I'd be up for a 4 hour race.
 
RE: Re: RE: Re: RE: Re: RE: 19" Ice Tire - Gearing Sugg

NSman you are right, 24hrs on a lake is a LONG time. Back in the day we used only a pickup for support vehicle. We slept suited up, with the heater running. The event holds a world record for the coldest motorcycle race at -40. And it was that cold for days before and days after. The needle barely moved. It was sick. One of my team mates froze his own thermometer, he has a small tear in the crotch of his suit and frost bit his unit. All in the name of fun.

You never know what you might start Kelsow, its a ton of fun.
 
no matter how cold it is, once you tug the throttle on the big 6 fitty you have so much adrenaline flowing you forget all about your frost biten cheeks. Besides where else but on ice can mere mortals corner with the speed and aggression of RC or Bubba.

ice rocks!!

Hey Nizzo,
I can remember you telling me about your 650 plans at LMS and getting that glassy eyed race face.. :D
 
nsman,

and imagine...that was before we actually rode the beast. Now that all the race prep is done we have 6 hours of testing on it, jag33 and i are even more amp'd up. the season starts Feb 3...we'll let you know how it goes. Its looking like the season will be 5 six hour races (and as Fryguy said: no numb bum :cry: ).

nizzo
 
Nizzo, any details you could give as to track layout and classes might be useful or,
is there a website we could see that explains the details.

How many people do you have turn out to race and to spectate?
Any sponsors?
Any trouble from the locals or is the lake far away from them?

Sorry for all the Q's
 
Kelsow,
The group out here is actually quite organized when it comes to putting on the races. their website however could use a little more attention wwwaeira.com the courses are typically 5 to 8 km's long per lap including both big and small corners and a couple huge straightaways. they have a transponder trailer and every bike runs a transponder. there's a realtime tv screen that updates every 30 seconds or so...gives you last lap time, fastest lap time, and current standing (both overall and in your class). The classes are bike over 400, bike under 400, quad over 400, and quad under 400. Only bad thing is they don't differentiate between 2T and 4T, which means you can run a KTM 380 2T in the bike under class (cheating I say). The lakes are either out of ear shot or they have the communities blessing (and sometimes sponsorship, like numb bum). There is no limit to the number of riders per machine or the number of pits allowed. But the top teams normally run two riders and three pits...there comes a point with long motos (2+ hours) where you're faster with an additional pit and a fresh rider. There's no restriction on tire or screw type. We see anywhere from 30 to 60 teams at an event, but lately that is diminishing. I think people are not interested in the financial commitment to go fast..not sure, we fear for the longevity of the sport as well out here. Me, i dream all summer long about backing it in at 70 mph. As you know ice is so different than any other type of riding (I would guess a grass track would be the next closest thing however traction is way different)

oh ya,
and they run a couple plows and a couple of sweepers full time for the entire six hours...clean ice is imperative!
