• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

SMS 630 gearing?

yeah. i dont want to waste money if i font need to. op pu is an o2 sendor with resistor delete. search

i went with 14t front. and kept oem chain. but now want a 42 rear for a bit more power.
 
what are your specs on the bike. 14t front is equals to +3 in the rear. there is no way i can power up the wheel in second. it barely comes up with clutch. i have PU corked cans and jd fuel controller.

Well, just my .02 here, if you are going brand new sprockets, why not get a brand new chain?

I have 15 front and 40 rear and am pretty happy with it - I can hit 95mph on this lil bastid (have no idea what the redline is or end of my Rs) which is fast enuff for a lil single and 2nd pops up with ease and 3rd is breaking in nicely - I know some guys go 42 in the rear and the ones I know of, went with s new chain to accommodate - Honestly, the Exhaust, PU Kit and ECU would be my first start - Yes, more $$ then the Sprockets but the motor is so corked up from the Factory that it just needs it to perform, and perform it will

What is PU kit? Why new sprocket and not chain? Because bike has 500 miles and there is no sense to replace chain, because it's new..

PU = Power Up kit. It's just the brass Lambda plug and resistor plug.

Like I said before, uncork the engine before you start playing with gearing. Chances are you won't need the gearing change once you've got it tuned up and dialed in.

Power Up Kit - Do a quick search on her and plenty of insight on it - Capice on the 500 miles - Not a chain expert but will a chain meant for a 38t sprocket handle the extra "tug" if I may of 4 more teeth? - I really do not know and am asking the masses here

Stock front and 40t rear - Half Leo System w/PC5 and Auto Tune - To be honest, I almost looped it the other night (or so it felt, prob had like 4 more feet left) with just a slide back on the seat a tad, 2nd gear 4K rpm WACK and she came up to about 11 o'clock in a hurry - I am getting small 3rd lifts when WOT in each gear as I bang thru up to 6 - Cannot wait to get the screens on the AirBox and see what else this bike has to offer

Going up in the rear does not increase chain tension.
Going down in the front does.
It's a 520 chain, you won't stretch that prematurely with any thumper...
Now we run Regina Gold 520 chains on our FSAE cars, and we stretch them a bit, but that's with a 12tooth sprocket, ~90hp, 7" wide tires and hard launches...

Gotcha -Thx Man
 
any brands you guys recommend other than oems?

I'm tempted with "JT" brands cause I can get a set of front and rear for the price of a rear only Sunstar, but kinda worried if they're crap.

any help would be nice...thx!

EDIT: sorry to bring this old thread back from the dead :D
 
Iron man ( dirt trick ) sprockets are great quality and last forever. They come with warranty, are very lite weight and look cool!
