Isn't there a raising link available for the back end? That would sharpen up the steering.

Pulled apart a couple of the stock controllers, gutting them to house the Nuclear controller. The capacitors are rated to 80V form memory. Didn't bother looking up the spec of the mosfets. Fell under my planned 18S (75V) application. Wouldn't go beyond that though.

Walking on the edge there. But hey, that's where the fun is.
Have yourself a spare controller on hand so your bike isn't down for too long.
I was personally underwhelmed doing voltage mods to the stock controller. Bit of extra top end speed but no additional torque on acceleration.

So after over 2,300 tubeless miles it was time to replace my trusty Bridgeport M403 with the newer M203.
The first tubeless conversions I had to use a strap around the tire to get enough of a seal for the tire to inflate. It really was the most pain-in-the-ass task in the whole procedure.
Welp, this time I removed the the spoke protector rubber and used a narrow strip of gorilla tap in the U-channel. I then added another slightly narrower band in the U-Channel over that to kind of fill it in. Then one more band on top of that the full width of the rim.
This gave me a good enough seal to eliminate the need for using the strap! Filled right up with just an air compressor. It's such an easy process now I could not recommend going tubeless enough.

Yep. At least two vendors on eBay sell them. Available in +3/4" and +1 1/2".

Sounds right. The controller amps would stay the same, so torque wouldn't change. Just top speed. Should go 12% faster with 18s. 50 mph?

Can you make a bridgeport tire on your bridgeport mill? What size is that, does your wheel have the little safety ridge, do you have to use a sealant of any sort, what pressures do you run? just a couple of questions I'm glad I'm not the only one with the swingarm smear from the pesky migrating kickstand.

Heh, well, shows you where my heart is. Sorry I meant Bridgestone.
Here is a complete list of what I used:
Gorilla Tape: https://amzn.to/3nn5rrt
NoTubes Tire Sealant: https://amzn.to/3s3t6k9
Valve stems: https://amzn.to/3hTYpct
Injector: https://amzn.to/2LziGrJ
Bridgestone M203 https://amzn.to/3nooJwH
Also a tool to remove the valve from the stem. My valve stem cap has a tool built in.
Use 2-4oz of sealant per tire - bottle above is 16oz.
You can get by without the injector and valve removal tool if you pour directly in the tire but I think they are worth it.
Just let me know if you have any questions.

My understanding (and of course I could be wrong) was that rim locks are primarily to prevent valve stems from tearing. That is not possibly an issue with tubeless.
3DTOPO said:sc-surfer said:Also, what pressure are you running? Any worry about spinning the tire?
I think around 12psi and spinning has never been noticeable let alone an issue.
sc-surfer said:Rim locks Pareto keep the tire from spinning on the rim, which does indeed rip the stems off. However, even spinning a tire without a tube in it is not great.
sc-surfer said:At the minimum you don't move forward (usually when climbing or accelerating) and at worst you break the rim seal and get a flat.
sc-surfer said:At 12psi on a Sur Ron you're probably ok. Not really sure.
sc-surfer said:OK just being that the tire will stay on the rim. At that psi I've not had any issues. As for spinning and not breaking a seal, I'm skeptical, but maybe.

That's thing. I shared that it has been 2,300 trouble-free tubeless miles for me.
If I was like "can I run tubeless for the next 2,300 miles", then it might make sense to say "it might be OK" or it "can't hurt to try".
