The engine is very smooth, and I have felt mimimal vibration at all speeds up to 88 mph, as indicated on the speedometer. :tup:

Thank you for correcting my error. I am almost completely ignorant of Harleys and the big cruisers, and these exceptions escaped my memory. ;)

CSC reported the handlebars are aluminum. I just checked, and a magnet won't stick to them. They certainly seem to be aluminum to me. ;)

I just measured the hole in the handlebars; it is 12 mm in diameter. Tapping the hole to a 13 mm thread would certainly work. :tup:

That is an excellent tip. :tup:

88mph? :hmm: Oh, come on. :lmao: It isn't even broken in yet. :crazy: You expect us to believe that? :p What did you do, ride it off a cliff? :tdown:


















88mph! :yay: :thanks: :hi:

By the way, how do the stock tires feel on pavement?

The Gas Gas Cami 250, and the AJP PR5 also employ the ZS177MM/NC250 engine. Both bikes, and their engines, get excellent reviews. :) Indeed, I consider this engine to be a well proven success. :tup:

I haven't had any problems finding neutral, whatsover. :) However, I never try to shift to neutral while moving. :shrug:

Given Qwerty's excellent suggestion to tap the holes inside the handlebars, I am going to see if the Tusk D-Flex handguards meet the other fitment requirements. ;)

The clutch lever of my RX3 did have excessive play in the cable when it arrived. I adjusted the lever for the proper amount of free play before my first ride, and I haven't had any problems whatsover finding neutral while stopped. ;)

:lmao:

My friend Andy is a professional mechanic with over 30 years of experience. He told me he believes it doesn't make any difference how you break in an engine. :shrug: After learning the Zongshen factory runs each bike to 90 mph on a dynamometer at the factory, I decided not to baby my RX3 engine during the break in process. ;) Indeed, a lot of guys advocate a hard engine break in, and they seem to get excellent results. ;) Therefore, I have merely been modifying the engine rpms, and I have ridden the bike on the interstate at full throttle. ;)

The speedometer is probably still at least 10 percent 'optimistic,' but I have cruised at 84 mph, and actually reached 88 mph on a short, slightly downhill stretch of pavement. The stock tires feel great at all speeds on pavement, and the bike always feels stable and well planted. This bike is a lot of fun to ride. :tup:

There are several branded RX3s around the world, like the M1nsk (Byelarus), and the Honley (UK), plus distribution in China, Chile, Peru, Argentina and Brazil under the Zongshen name.

Here are a few other bikes that use the NC250/ZS177MM engine:

• AJP PR5 - fuel injected, manufactured in Portugal, sold in US
• Apachi Cross XZ250RM - sold in Turkey I think
• Megelli 250R
• And this sportbike from alibaba

A thing of the passed...

88mph isn't bad for a 250 pushing that much weight on a tight motor...

Hey, we have to watch out for one another. Those S. O. B. (Some Other Brand) riders will start all that not waving at Chinese bikes crap.

I've never heard of a 13mm bolt. 12 and 14, yes, but not 13. Hmmm? Guess what size hole needs to be to tap for a 14-2 bolt! Yup, 12mm. Hold on a sec. ... ... ... Okay, I just ordered two taps off eBay. Once I've tapped my bars I'll mail a tap to anyone who needs one as long as they promise to pass the tool one to another Cyclone rider.

Oh, wait! Will the end of the guard have enough material to take a 14mm hole?


If not, I have some thread inserts that go into about a 12mm hole and they came from Advance. Advance just might lend the tools to install. If memory serves, the inserts are less than $10.

:hehe:

Qwerty, sign me up. I'm going to want hand guards on the bike sooner rather than later. I don't want to have to practice changing levers out in the event that I drop the bike.

Looks like taps are done manually? Do I need to get my hands on a T handle?. I see I'll be augmenting my tool box on account of this adventure :P

Let's wait for SpudRider's take on whether or not there is enough material to handle the 14mm hole, and if the rest of the kit will fit. Then we will go from there.

Most wise. Thank you for offering to share the tap around in any case!
