Cannabis in deep water culture hydroponics. I lost my last grow a year ago to spider mites and haven't grown again since though. Hotrodding plants was fun though.

I need brake pads, who’s got em or what’s compatible? Seems one of my rear pads is already hitting the backer. Since I am almost 100% front brake user and my front brake pads are still at 90%, I’m calling shenanigans. The rear caliper is not applying pressure evenly at all, looks like just one piston is doing all the work.
Threw the supermoto rear with 48t sprocket in today. Rollout measures 12% lower but only lost 6% top speed as checked by roadside radar.
Definitely a keeper combo! I wouldn’t mind even more gear reduction.

I just cut up sheet of 7075 for 58t sprockets because that is all I have sold, no 52t.
I am not making any more 52s for now. I might do a run of speed sprockets for the motard wheels.
What tooth count should I make?

#1.Buy the Sur-ron= bad ass/speed/out of box/etc. $3,400 roughly
Or #2. Buy a 3000w cyclone put on my fattire bike plus controller/etc for $2 grand less estimated.
$1,400 roughly. But looks more like bike/gears/pedals to ride home/less harassed by people. But then again parts bolted onto bike frame not really designed for an electric motor.
Tough decision....aghhhhh
GPS logged 70mph running stock gearing ratio (slightly downhill road, still amazing.) This motor responds well to heavy field weakening on top end for big overspeed potent above BEMF and pack voltage matching point.
The hotrod is very quick, pulls even with FX up to ~40mph, but a stock DSR when both bikes get a clean start pulls on it slightly until 35mph and starts to run away.
Going to swap from stock gearing to 60t rear and it should pull even my hotroded DSR up to maybe +40mph, and still go fast enough for my off roading skills. It drinks its pack up in big gulps now, but the gulps are each pretty intense with its wheelbase and weight making its wheelies rise really fast to manage.
doesn't the 17" diameter Sur-ron supermoto wheel kit now available from luna include a 42t rear sprocket (and correct length chain) to make the kit bolt right on and maintain the same top speed as the stock 19" diameter dirt bike wheels..

the supermoto wheel kit would also be a good option for shorter riders since it will lower the stock seat height by ~1".. and you could also run 17" dirt bike tires (such as shinko 241 etc) on the supermoto wheels for off-road or dual sport use.. 8)
