Thanks! I'm in east Mesa. 175's are nice. Last summer I had 2 x cb200. But I always like the 175 and 125s more.

Well here is my seat after some terrible fiberglass resin work. I'll sand it and clean it up a bit but it will be hidden once the pad goes on.

The idea is to use the original seat pad cut and wrapped.

Obviously cut a reasonable amount to wear it is pretty thin and them wrappe with either a black or dark brown cover. I'm going to try to have more o it done by the end of the week.

Ok well I ditch the seat idea I had for something my wife suggested. She said I should make the seat two parts. One part cowl and one part cushion. I took her up on it and actually I like it so far. The cowl is on. Altho it's sits about a half inch lower than the tank it was easy to attach and now I can focus on the cushion. Here is how it looks.

Once I figure out how to add the cushion section I will remove the cowl and sand and paint. Probably black again. The I will start focusing on cleaning it up. I really want it to look a little rustic and not look like a show bike. I also hope to relocate the battery under the cowl eventually. Or find a way to make some decent side covers out Of sheet metal. I'm not the best working with the materials so we will see how that goes

Here is a better pic / idea of what I'm doing. I used the stock seat foam as it has nice curves and density.

Sorry about the crappy image. I'll have to learn to sow but I think it will look pretty good in the end.
 
I made the misake of looking around the forum and notice a few things. My craftmanship is garbage. I don't know how to use a welder, fiberglass, paint, etc. I will say that I am happy however hosw its turning out. I really like what most people on here are doing and am blown away that alot of them ar just weekend warrios and not custom bike builders. Really impressive and keep up the good work. Really inspiring stuff.

Ok guys. I need your help. Its go time on the seat and I need to know what you think. Tomorrow I will start the pad and I'm kinda in a bind as to which one will look better. Should I do the diamond stitch like in the drawing above or the ribbed stitch? The seat and pad, I think are going to be way better than projected considering I have no experience in this. I just want to get this part over with so I can button the project up, clean the bike up and ride it like a stole it. Please feedback would be welcomed as to which way to go!!

It is all about being built and not bought with that in mind your bike looks great. Don't worry so much about your craftsmanship it gets better each time. I like the diamond better than the stripes but be careful you probably don't want a 70's chopper seat look LOL. Overall your bike is looking good keep it up
 
Is there any way you can get the cover to fit the shape of the seat without the stitching? I like the clean look of no lines on a seat.

Yeah, to make it with no detail is actually the easiest route. For some reason I feel like this bike needs a little detail. Another thing, I feel like by doing the ribbed or diamond stitch it will hide the imperfections of the seat cushion better.
 
Adding a pattern definitely helps hide the flaws.

My flanel has more oil stains then the god damn talladega superspeedway, but no one can tell!

Well while Ike waiting for my sister to finish my seat, since I know I can't sow worth of sh!t. I notice my bike wont idle and barely starts. So I tried Cleaning the petcock and checkin the spark plug. The plug looked fine, and so was the petcock, I could get it to start after a few kicks,etc but not as easy as before. The bike had been sitting most of the summer because it's to cot damn hot in AZ.
So I put a new battery and charged it overnight. It still was the same. So today I remove the carb and now I'm planning on taking it apart tomorrow.

With th carb off tho I don't see any real adjustments like my Cb500 carbs. What is this adjustment on the back of the bowl? I know the idle adjustment screw is on the side. What is this adjustment? As it only turns about 240 degrees one way before it hits a stopper.

I haven't remove the bowl yet, because I don't have a replacement gasket. Assuming it has one like other Honda carbs.

My question is, does anyone have any other recommendation if what I should try to get it to run.

I can get it started and drive it around the block but it will die if I don't hold the throttle. I also get the impression I am running lean. As its kinda sputtering at 5000rpm.

Keep in mind it was running just fine earlier this summer.

I was wondering if perhaps the throttle cable being a bit long could have something to to do with it cutting out. Maybe I need a shorter cable. Which seems silly as with the idle screw it should still hold idle right? If I'm correct in the further in the screw the higher the idle.?

If any of you are families with this carb please advise. Btw it's a 1980 cb125s.
Here is the choke side which also has no adjustment

Run some sea foam through it. The carbs might have gotten gummed up after sitting. Also if it wont idle you could pull the air/fuel screw and spray some carb cleaner in it to try and clear that circuit. I imagine the air fuel screw is your mystery screw. It is usually recessed and also is set around 1 1/2 turns out from all the way in. Your best be is to get a gasket and clean the whole carb good as new.
 
Just pull the carb apart. It's really stupid not to do that after it's off the bike anyway...
I guess the bowl has a rubber o-ring gasket, wich can be re-used for once or twice.

Just do it, dont be afraid.

Well I ordered a oem carb kit. In tthe mean time I took what I had and diaassembled it and re-assembled it. Put it back on and it seems to run ok for now. It will hold idle and start fairly easy. I think I will still rebuild once I receive the kit. Seems easy enough. I also will set the valve clearance and put on a new plug. In the mean time I'll start looking for a small taillight solution. I am looking for something pretty small. Can I make on of those little lights you see on the side of diesels work?
 
looks like that is LED? Can you run leds base on a 6v system? Also does anyone know how capacitors work in regards to removing the battery. I have read that I can use a large capacitor in replace of the battery. Has anyone done this? also how about electronic ignition instead of points? is there an advantage? - I guess the final question is can I run electronic ignition off a capacitor?
