It made it back just fine, but I wanted to say that I have come to the conclusion that a wheel with 14ga spokes, using a rag joint type sprocket coupler just doesn't hold up on my bikes on these rough dirt roads I ride on at typical cruise speeds of 35-40+ MPH

I've always been a bit concerned at how the kit coupler really stresses the 14ga spokes when its tightened down since it really pulls them outward like it does, but now after having three different 14ga spoke rear wheels on this bike and all of them having issues I have decided I will not be using a "rag Joint" on a wheel with 14ga spokes again.

My oldest bike has the rag joint on 14ga spokes and has more miles on it than all my other bikes and has had no issues so far, but it also has a much weaker engine and only cruises at 25-28 mph so that may be one of the differences compared to a bike that will cruise down these rough dirt roads at 40+ mph.

Yep the most recent wheel on the Kulana bike looks to have broke 4 spokes on the drive sprocket side under the coupler so what I will be doing to this bike next will be putting a rear wheel on it that has at least 12ga spokes and since I'm a huge fan of a good coaster wheel it may be getting that so I can just eliminate the rag joint coupler all together and use one of my hub adapters for a much stronger and more reliable setup.
It seems to me that hub adapters are the best thing that s happened to those type systems. Also Staton Inc. has all kinds of goodies including hubs and left hand free wheels, adapters etc. for just about everything. They also sell heavy gauge spokes. I could easily spend all day just browsing their site. if you click on these links, you will see pics of my system where the adapter threads on to my hub.

Yup, Steel rim with 12 guage spokes, I've said it time after time. If ya ride REAL light, ya might get by with an aluminum rim and 14 guage spokes. But a rag joint putting extra stress on what are already a light guage spoke usually works out just like what ya got now. a wobbly wheel. most bike shops will sell you a steel rim with 12 guage for about $50. Then, of course I'm in favor of adapters too. a rag joint will work if set up on a proper wheel. I just don't think a aluminum rim with 14 guage spokes is good enough for that. I have a customer in now that FINALLY,(after 3 bent wheels) went down to Bicycle Express and spent his $50 for a proper wheel. He should be OK now. You might get the aluminum rim with the 14 a little cheaper, but in the long run yer gonna spend more replacing bent wheels.

I don't weigh enough to have problems with 14ga, but I can throw a set of 12s into a wheel in about an hour (which could have been 1/2 hour back when I was much younger) - seems a shame to spend for a whole new wheel.

Did some tinkering with the jetting on NT Speed carb. Seems to like the #60 the best --- no 4 stroking on acceleration and ocassional 4 stroke on mid-throttle cruising. Got the needle on the 2nd groove from the top. It's really surprised me at how far I've had to jet down.

By the way, I've got a Huffy 26" rear coaster wheel with 12ga spokes (minus the roasted internals) that I'd be glad to pass along. It's red in color with stainless spokes.

Changed a rear tire flat yesterday. It never ceases to amaze me how a 3" deck screw lying flat on the ground can see me coming then jump up vertical just in time to sink itself into my tire. Crazy...

The issue for me is Im a tad over 200lbs and I literally ride miles and miles of very rough dirt roads.

If 8 was riding pavement only, most likely I wouldnt have had the issues on this bike, but when I at a 40+mph clip and I hit those chug holes and deep rub board areas in the road it puts a razy amount of stress on the entire bike, I have springer front forks that absorb a good bit of the punishment up front, but the rear wheel really take a pounding.

My Huffy Karaoke bike has never had an issue since 2010 with the stock steel wheel and 12ga spokes qnd it has at least twice the miles on it as the Kulana bike that will be on its 4th rear wheel when 8 get the current one replaced.

Ive though5 seriously about just getting a set of spokes and lacing one of these wheels up myself, but Ive never laced a bicycle wheel and actually only laced one dirt bike wheel wa6 back when I was about 15 or 16 when my brother broke some spokes on his old 1980 Suzuki DS100 when we were kids, we completely relaced that wheel got it just a tad less than perfectly true.

My main issue is time, I just dont have time to lace wheels right now since it would probably take me a good long while to get it done.

not really hard to lace - back in the day, I laced harley rims onto triumph hubs a lot

once I laced an MG sports car rim, but that was a lot harder

many bikes need a bit of truing every so often with the strain put on by the speeds these reach - much like "a stitch in time", a bit of truing will prevent a rim from going wobbly enough to cause real problems

For what a hub adapter costs, you could get a moped hub. That's a huge step up from even a hub adapter, and then to sweeten the deal you get a drum brake that was actually designed for even heavier use than we give them.
