It's just really nice to pop the front wheel up over a tall rock stair step. Maybe easier for you more competent riders but for a n00b like me, it's nice.

The NX second gear swap should be done when the case is split. That gear is cheap and easy to find. It eliminates the gap between the steep XRL 1st and second gear. If you get the fifth gear 14/48 will work great for all around use.

With a built engine and a pumper carb you have enough power to wheelie at will in 1-3 gears with 15/45 gears. It will pick the front end up in all 5 gears if you try.

A well built engine with 14/48 finals almost has too much power. It just keeps trying to ride away without you...

Whats nice is having a gear for every use. No need to change countershaft sprockets for long slab rides or tight woods use.

I couldn't really justify the expense at the time, anyway.

I started out with 14/48 as I got it from the P.O. I needed a higher top though the first three were fine. After some time, I tried the 15t front. I determined that made the first two or three too high, so I went back. Then bwalsh had a 50T rear he wanted to get rid of so I did the arithmetic and 15/50 is 90% of the stock 15/45 while 14/48 is 88% -- so they are close, but 15/50 is just a touch higher. That's what I'm running now. It's an okay compromise. If I could have the first three gears in 14/50 and fourth and fifth in 15/45, I'd do it. But as long as I'm wishing for the stars, I might as well wish for a six speed where the gears are spaced exponentially.

I've thought about that second gear alteration while riding, and I just don't see where and how I would personally benefit from making a smaller gap between first and second, and a larger gap between second and third. It seems just fine the way it is! :
If you want to eliminate the 2-3 gap, use an XR600R first gear (taller/closer to 2nd than the OE XRL 1st). Add 14/48 final and you have a very linear gearbox 1-5... BUT you give up quite a bit of top end speed.

That make a nice close ratio box. They are a blast too. Each way has its upsides and downsides.

I bike set-up each way would be nice...

Anywhere you have gone, at speeds that suit you, quite possibly so. But there's a lot of range from places where you need to crawl over large obstacles and.or make a series of tight turns, to trying to get several miles away on the highway and stay ahead of traffic. I could probably deal with the 14/45 compromise but I can assure you 14/48 is much friendlier on the trail. I do way more trail than road but I don't want to burn up the engine nor become a rolling roadblock to and from the mountains.
Hey if we can't have a six-speed, then how about a dual-range??

That's cool, but I got perfectly used to the 1-2-3 gap, even-4 at times, on the mountain trails using 14/48. Top gear just felt like I could not go for long over 60mph without risking abuse to the engine. Although I would wind it up to 85 on some gravel roads, that was where it topped out and I had to let off after hitting it.

There's little to nothing we can do ourselves to make it proper to include good low end and good top end - it's an inherent limitation in the transmission with the parts available. But we can dream....
When we're done dreaming, we can search for our best personal compromise.
At the moment, mine's 15/50.

If you look at the chart you'll see the 5 speed NX650 euro gears are wider then many good 6 speeds are.... No compromise needed.

I have an engine build plan to match up with it perfectly.

Now I just need the money tree...

If you look back at any of my ride reports my riding is 90% off road. Did Kane Creek in Moab with this gearing, a fairly tough trail.

I have never asked and always wondered. What approximately does it cost to have a "built" motor? I know there are tons of options and my question is very general. Never had the nerve to ask Cdub, but is a CW790 like 2500.00? Does a thousand get you anywhere? Always been curious. Strictly engine mods.

Steve ,

My understanding that a Completely tricked out C-dub motor , with every single bell and whistle than you can think about , plus a few that you cant think about , will run you about a thousand bucks .

I think that's really reasonable. Especially after I priced leathers in our size.

I think your pretty close at $2,500. I think he leaves nothing to chance & takes pride in his work. You sometimes get what you pay for

If your engine has a good bottom end a grand will add good power.

That would get a nice top end, cam and head. Add some for a big bore kit. This price will vary if you can swap the parts yourself.

If you want an all out CW engine the price gets up there. He builds wicked cams, custom stroke cranks, longer connecting rods and has a bunch of other tricks up his sleeve. If you had one of his motors the NX gears are just icing specks on the cake.

"I saved the message I sent to another member and am copy/pasting bits of it to you:

I bought a new/rewound stator from
Ricks Motorsport electrics Inc, for $140.00 OTD, part# 21-119.(it fits a few different bikes-some are 1984-87 Honda VF700C Magna).

http://ricksmotorsportelectrics.com/...RIb25WRjcwMEM=

should be Honda part no. 31120-MK3-004, or 31120-MB1-024,(one part number supersedes the other)

other things I had to do:
pull the neutral light wire back through the stock stator sheath,(I didn't want to cut the stock sheath).
carefully slide the grommets down to where they lined up with the stock location to seal it and use heat resistant silicon (similar to flyingwombat) ,
and cut down the grommet so it seals the most effectively,
I modified the bracket inside the stator cover that holds the wires coming out of the stator so it lessened the pressure on the wires,(might not be necessary for you).
used longer bolts to bolt on the thicker stator,
if you go with a re-wound stator make sure there is no lacquer/sealant in the way of making the stator sit flush with the mounting surface.

I did upgrade my stator also:
this is where I got mine: www.roadstercycle.com
I got the FH012AA, they are now selling the upgraded R/R, the FH020AA, this was the best deal I could find for the kit besides Ebay, (they had it for the same price).
I can't guarantee that this is still the best price out there.
I put my new R/R in the stock location with some brackets I made, the ground cable didn't reach the battery with the kit I got and ended up running the R/R ground cable to the battery ground on the starter to make it work. "

If I get into my trans again and have the available coinage, I will get an NX 2nd and 5th and go back to the OEM XRL 1st. Swap out the 14/48 final for something along the lines of a 15/48. I like the XR6R 1st that I have in it now, but I sometimes miss the top end speed (she's done at about 75-80mph). I really do like the XR6R 1st and 2nd on the trail though. No big gap is nice. A gap between 2 and 3 would seldom be an issue for me off-road as most of my trail work is 1-2.

If Barron cannot or wishes not to get a NX5th sales business going or if you want one now I used this guy recomended by another inmate here.

http://www.motobike.jp/

Was hassle free, just asked him if he could procoure part number 23491-MW-2-780 (NX5th)

He replied yes asked for payment to his PayPal account and my address.

So 9400 yen (approx $110.00) later and less then a week and i had a nx 5th gear and couldn't of been happier with the experience.
