Cheapish options on eBay which are a little differenthttps://www.ebay.com/itm/132402520922
I'm running a Mishimoto radiator from some dirtbike, likely a CRF. I got a killer deal on it and the spigots are in convenient places for mounting it higher.NX50 frame, NU50 crankcase + transmission, PA50 forksIn the future I'd run a used dirtbike radiator or cheap aluminum unit since they're abundant and cheap on eBay.
Nice setup! Where did you find the QMB/GY6 50 Stage6 clutch for sale?
I've seen the 6-star Kreidler mags on eBay Germany a few times in the past when I've been casually browsing. If you're determined to score a set, I'd start there!I picked up some Honda PX-L 14" snowflake mags for pretty cheap there (under $200 total) so it's not outside the realm of possibility to score a set of unusual rims for a reasonable price.
Looking to buy the crankcase halves from an NU50 Urban Express. Thanks!
That looks awesome, good job with the install!!
The master cylinder and reservoir are a single unit, in this case.Any master cylinder should work in theory, it doesn't have to be for an MB5.
Totally, why not! The brake line is a universal part.If you're going to go through the effort of replacing the master cylinder, you should also replace the old brake line and copper sealing washers.
What fork assembly was used with this build?
High torque urban builds snap stock connecting rods. It's a good investment / peace of mind.Performance decrease due to any reduction to crankcase volume should be negligible.
UPDATE TIMEI've put a ton of miles on my water-cooled Express SR. The Malossi H2O cylinder kit has held up impressively well; I'd buy another one in a heartbeat. The bike has served mostly as a loaner at rallies for others who don't have a bike to ride.Current Parts ListMalossi H2O Hobbit cylinder kitMLM H95 NU50 exhuaust.4 mm carbon reeds24mm Mikuni TM24 flatslide carburetorK&
Word, that's not too shabby! Did either do you guys have to seek VIN verification / "letter of verification" from local law enforcement?
Any updates on the registration debacle? Currently looking into this procedure for a couple of bikes and wondering if there are any new requirements. Thanks in advance!

@Bonnie Blake, the "Express SR" was not produced in 1978, nor were there yellow versions, only blue and red. You have an older Honda Express.
How's the gas tank? Pictures?
Kreidler MP motors have aluminum cylinders with a nikasil coating.
I usually add shims on each shaft until the cover won't fit, and then remove 1 - 2 (.1mm) depending on how the shifting feels afterwards.
Hello Kevin!I documented everything from my last rebuild here: https://www.mopedarmy.com/forums/read.php?7,4083181Specifically for the bearings, I purchased mine from Myron's mopeds. Feel free to PM me with additional questions. I also have a ton of spare engine parts.
I definitely need this part and can pay whenever, however I think everyone in this thread is in the same boat :)What is the seal spacer?
Also still following. Willing to pre-pay for however many sets needed to get these actually produced.
I love you Will, but your potato camera is very apparent here.
Here I was, thinking I was the only person with a water-cooled NX50. Nice build!
I have the Urban H95 on my NX50 (basically urban express). Broad, impressive power delivery with both VM20 and TM24 carbs and HPI. It is loud, but not nearly as loud as a Proma. The baffle snapped off of mine within the first 100 miles, currently awaiting a replacement.
Bump, I will buy as many sets needed for you to produce a few sets of these adapters!After getting my "no expenses spared" NX50 build running, I have determined that my stock-crank-with-forged-conrod and 70cc piston is quite out of balance, causing the fuel to foam in my Mikuni VM20, which causes fuel starvation, which doesn't allow me to ride at higher speeds, etc.Long story short,
> DPC Ryan Wrote:> -------------------------------------------------------> If it needed a 90 it would not even get moving with a 160.This thought occurred to me, however it is very curious that most 70cc build specs I have seen using the VM20 have sub-100's main jets. Strange.
Miss ya Marvin, I hope all has been well!!Update, I earlier deleted the vacuum petcock for this one from Amazon. Spoiler alert, it's way too big. I instead purchased a Magnum petcock from Treats
