Honda Aero nb50 to nh125 Swap Project

Re: Honda Aero nb50 to nh125 Swap Project
The weather was good enough to ride so I did some experimentation running a 150cc gy6 variator on my nh125.
Comparing parts, ended up using the nh125 ramp plate and boss on the gy6 pulley to make it work. It rides pretty nice, helped acceleration and top speed. I'm using the 13g weights it came with but need to order some different weight rollers.

Checking back on the variator, I made some sharpie marks on the pulleys and they got rubbed completely off on the outer pulley. But there's still marks on the gy6 variator because it's wider than the stock nh125 outer pulley. The gy6 outer pulley has different spline than a nh125 so I can't use that.

I need to find some new haters...the ones I have are starting to like me.
Re: Honda Aero nb50 to nh125 Swap Project
Can you list the spline count and diameter of the pulley? That things huge looking! I wonder what else it can squeeze on.
Re: Honda Aero nb50 to nh125 Swap Project
Here's a link to where I bought the ch125/ch150 pulley from, it lists some dimensions. It has 21t on the splines but so does the Gy6 pulley but it's a smaller size and wouldn't fit, I don't have the measurements off hand.benji wrote:Can you list the spline count and diameter of the pulley?

Re: Honda Aero nb50 to nh125 Swap Project
Yeah thanks Mike for hooking me up. The weather here is too crappy now for high speed test runs, also need to order some different roller weights. The belt cover barely fits with the ch125 pulley but it works. Speaking of upgrades I've decided this aero deserves a ct intake upgrade, it would be that much more fun with a bigger carb.motormike wrote: ...did the pulley I sent arrive in time to accomplish your goal ?

Adding the intake and TM24 Mikuni to my Aero was an astounding success.Tyler VR wrote:Yeah thanks Mike for hooking me up.

There has been some criticism about the quality of the intake by graphite9. Check your intake for good, flat mating surfaces.

Yeah same thing on the intake I bought off ebay last year, took a little sanding to get flat.motormike wrote:Tyler VR wrote:motormike wrote: Adding the intake and TM24 Mikuni to my Aero was an astounding success.
