Devin

New Members: Introduction

Hello and welcome!


My Name is Devin. I designed and maintain this website. It is for everyone to talk and share information, about Yamaha 2 strokes. It is mainly focused on Yamaha Enduros, but all Yamaha 2 strokes are welcome.


I have gasoline running thru my veins. I bought my first Yamaha Enduro when I was 16 years old. I currently own 175+ Yamaha Enduros. Yes, it is a real sickness! but it is better then being addicted to drugs or alcohol! ๐Ÿ˜‚


I served 20 years in the Air Force. During that time, I deployed 8 times. I was a vehicle mechanic, and technical school instructor, teaching students, on vehicle maintenance. Now that I am retired, I can fully dedicate my time and attention to vintage Yamaha 2 Strokes.


My favorite model is the 1970 Yamaha CT1B. I love them so much, I have 17 of them. I lookโ€ฆ

Welcome!

Newly Acquired Yamaha 125's



Bought the '72 for the wife to learn on, then bought the '75 to ride with her. Need to mount the new tires on the '72 and run thru the electrical on the '75. Both run and ride well.

I just sold an AT2 after a mystery issue. It barely ran but the issue was

It kept leaking fuel over the bowl. I did everything to prevent this but after

4 rebuilt carbs they all did the same thing. I had a expert rebuild one of the original carbs the he mounted and ran another AT2. Then put it on my bike and it leaked fuel over the bowl and wouldnโ€™t start. Remember, I put four rebuilt carbs on it and they all did the same thing leaked over the bowl. I dumped baby powder on it one time and let it sit for two days and the leak with splattering as you can see in the picture from the bowl to the intake it was ghostly

Please donโ€™t say oh itโ€™s your float adjustment, needle jet all that crap was replaced with the Mikuni parts on four carburetors!

I finally just got fed up and sold it

1970 Yamaha CT1B Front Fender

I have a 1970 Yamaha CT1B and was working on the fenders to get ready to paint them. The front fender is from a 1970-1972 175. I'm not sure what year. Does anyone know the material this is made from? I would assume it is made from aluminum, zinc, or magnesium, because it is not rusted, unlike the rear fender. I ask this because I was using a propane torch to get a few dents out, and it melted a hole right through it. Would I be able to do some sort of welding, such as TIG? Or would my better option be to use fiberglass or Bondo over it?

Most Yamaha Enduro front fenders were made of aluminum until the 1971 models came out. You can tell if it's made of aluminum or steel, by using a magnet.

Also, the earlier aluminum fenders had their mounting brackets riveted on, and the later steel fenders had spot welded mounting brackets.


As for repairs, there's a product (aluminum brazing rods) that I've used before, that might work well for you. Follow the manufactures instructions, and I suggest some practice brazing on a similar thin piece of aluminum first . . . metal must be very clean, and scratched up with some fine sand paper (400 ~ 600 grit), or use a "clean" stainless steel wire brush. . . . even your fingerprints from handling the fender can effect the outcome of your repair job.

Ohhh .... and use a temp gun to make sure you don't overheat the fender...

In other words, no higher then what the recommended melting point is of whichever brand of rod you choose to used. (roughly 750 degrees)

Rear sprocket โ€œwiggleโ€/play

It just doesnโ€™t seem right that this rear sprocket on my 1973 CT3 has some play or โ€œwiggleโ€ to it. Before I start getting into the damper and the bearings, I figured I would ask you guys what you thought?

?There are rubber bushes behind the sprocket - remove and inspect - replace the perished ones. they are intended to cushion your power delivery. Try YAMBITS for new ones - evil bay sellers have them too - have Fun!
