fuckin bastards...... we need a 38
What kind o' chains did ya get?
whatever they send... it's like a lottery... o-ring ones... i'm hopin there's a snazzy gold one in there.
Who is they?
From what I understand they make down to a 39 or 40.
I've got a 44 hard parts stealth coming, but they're on backorder until the 25th.
DID NEW X2-Ring series: D.I.D has redesigned the shape of the X-Ring to maximize wear resistance of the new 520ZVM2 and 525ZVM2 chains. These two models have also been beefed up in tensile strength to make them the ultimate chains for today's high performance sport and sport touring motorcycles. The new X2-Ring retains all the low friction, high performance characteristics of the standard X-Ring while providing a significant increase in wear resistance and overall life of the chain.
This is the shizzle.
This is good to know.
Whatcha gonna run up front with that 44T rear?
Currently I run a 45T stealth with either a 16 or 15 front with a chain 2 links longer than stock. I like the wheel positioned as far forward as possible, and this doesn't work so well with this combo. So I ordered a 44T rear such that 44/15 would barely fit with a stock length chain. What is it, 110 links, I think.
That's my goal anyhow, to get between 2.75 and 3.00 ratio and with the wheel as far forward as possible. Wish it were easy to calculate. Not sure all LC4 swingarms are the same length. On mine, I know that 45/15 was just shy of working comfortably with a stock chain.
on the way into work today i checked some gear rpm speeds for ya; i need to try again on the way home as they seemed to slip out of my brain... so this is a placemarker for later:
stock gearing and chain/sprokets
IMO set to 21"
modified breathing/carb (this should matter right? - HP changes this eh? )
rear tire a 25% or more used Michelin Desert/ front a MT17 (15% or more used)
no i don't have a measure on the rear circumference...
anything else pertinent? flat ground? no wind? bonneville salt flats?
1st - ~20+
2nd - ~30+
3rd - ~ um...
4th - ~60-65
5th - ~70-75
6th - (I wish)
what is your desire loaded?
do you need some field verification?
Be very careful when asking Loaded a question that's this open ended.... :eek1
he must be slippin' - he balked at first take.
workin on the car all night.... i'm fuckin tired today.
sure.... why not.
maybe i am not getting this. you are looking for gearing changes to optimize your 640a for your style. you have a spreadsheet of theoretical numbers.
is there no need for actual values to ensure you are on the right track? maybe with all that hardware you ordered there isn't.
dey aint theoretical numbers... they be calculated. that spreadsheet gives exact numbers for my bikes tire size. other tires will vary, but all you gotta do is change the circ number.
i ordered a bunch-o-sprockets and chains to see what i like best for different rides. i'll prolly leave the really big gear on my dirt wheels, and a shorty on my road wheels, but i wanna play to see what i like best... me thinks the 17-38 combo may be a bit tall with the power the 640 puts out.
fly at 'er... post yer numbers. more information is always good.
gearing is like pussy... some like em tall, others like em short.... i like em all, but i aint takin trailer trash to the golf club... knowhatimean?
shit is starting to show up. i got a 16 and 17 tooth front sprooketty today... a did xring "atv" chain which apparently is really heavy, and extra master linkeses... rear sprockets should be here tuesday (fucking long weekends )... i got caried away with rears... i've got 38 to 45 coming... 5 or 6 in total... not sure... none are the stealth that i wanted.. i'll order that in the config i'm happy with later... another xring chain too incase one isn't long enough.
as an asside... i ordered parts from all over the place in canada. dirtrider helped me out with the front sprocket bolt coz nunbody had one here. the rest of the stuff had to come from like 5 different dealers... i gave a timeline of one week to get parts and nobody could get it all in a week. some couldn't help at all.
when i ask for all the hardware for the rear sprocket and the guy only sends me bolts i get pissed. he said he understood me, but all he sent was bolts... no nuts! one lesson learned... just because he says he understands doesn't mean he does.
let the playing begin soon
So I take it you'll be coming down here turning all of 3500 rpm... at 90 MPH.
