I've used the eBay international shipping program a couple of times as a seller. It's nice, just ship it to a shipping hub and eBay takes care of the rest. Most of the time.
Here was my problem, I have a pair of used RD400 cylinders listed and someone in Australia wants them. But eBay has international shipping off and even after I turn it on, the listing shows United States as the only destination.
I found out eBay won't allow their international program for USED parts listed in engines and a couple of other categories. Solution: when selecting a category for listing, make the sub-category other motorcycle parts and the other countries list will populate.

Turning Wrenches / Re: reproduction caliper

I had the same problem on my RD400. I ended up removing the wheel, installing the caliper with the wheel off, then reinstalling the wheel and slipping the rotor between the pads.
If you look at the bridge between the 2 caliper halves, you can see it protrudes downward more than the OEM caliper. It could be trimmed with a die grinder. I just didn't want to grind on the caliper in case I had to return it.

Water cooled engine. Looks like a Daytona swing arm. Just thought someone might find this interesting.

Turning Wrenches / Warped Brake Rotor
October 01, 2024, 10:53:08 PM
My RD400's front brake rotor has about .007" warpage. In the past, I tried machining one mounted on the hat in a Ammco brake lathe. The result wasn't too good. Had a hard time chucking it and the lathe didn't seem to like the rotor material. Has anyone had any luck machining them? if so, how did you do it?

Not mine, I don't get this lucky. But A friend of mine found a brand new CT90 when he bought a lien sale storage shed. It still has the plastic wrap on the seat, 7/10 of a mile on the odo, and hasn't been completely assembled.
He asked me what I would do with it. I'm asking for input. BTW what do you think it would be worth?

Finally got the pipe installed.  Other non-motorcycle projects got in the way.  It wasn't an easy fit, took some heating and bending on the  inlet pipe. He didn't send a new stinger or muffler. I ended up making my own stinger. The muffler will take some modifications to work.

He sent another pipe. I set it in place and it looks like it will fit. When I get it mounted, I'll take a photo or two and share it.

It's really too bad that I had to file a claim with PayPal to get some action from him. It's a really good looking pipe and the cost was reasonable.

I just saw something interesting. A member of a Facebook group I belong to listed a 79 DT125 for sale. He's in England. His bike is a twin shock model and the downtube is different then my monoshock bike. Apparently in some parts of the world, Yamaha still used the older twin shock frame in 79.

Quote from: svgarage on February 18, 2024, 12:14:47 PMBe very careful about dropping your claim before the issue is resolved. I had an issue with a vendor not refunding money for an item that I had already sent back. I started a claim with my credit card and he suddenly became very communicative. He convinced me to drop my claim, because he saw that the credit card had already issued me the refund. Well that was the "provisional" credit, meaning that credit was in lieu of the money from the vendor. My only option when I dropped the claim was that the issue was resolved. So the credit card took back the provisional credit. Now I had no refund from either the credit card, the vendor and I had no product! The credit card would not let me reopen or start a new claim on the same issue, so I was stuck hoping/praying that I wasn't going to get hosed.

He asked me to close my claim several times. I did contact PayPal and asked them to place my claim on hold to give the seller a chance to deliver the correct pipe.

I was looking over messages between myself and the seller. The pipe he sent was not the one he sent me a picture of. He sent me a photo of this pipe installed...on a twin shock DT100. I was able to get in touch with him in December. He said he was very busy with a big Christmas order. After Christmas, no response to my messages.
I finally opened a claim with PayPal and that got a lot of response. He's going to have someone send the pipe out right away. Then a message to please drop my claim. Sorry he has been slow to respond but he's in the hospital (along with a photo of someone in a hospital bed with a IV drip).
So I'll wait and see if it actually shows up.

Quote from: 2 Smoker on October 19, 2023, 05:56:33 PMEvery time I look at this exhaust it makes sad that it did not fit, when I seen it I wanted one for my 75 DT175 :bang:
Funny thing is, I think this pipe is designed for the older twin shock frames and the seller assumed it would fit later monoshock bikes.

Quote from: oxford on October 17, 2023, 05:30:06 PMCurious what the fitment issues are?
The header pipe hits the downtube of the frame and is still 1" from the exhaust port. The mounting tab isn't even close to the mounting location on the frame. Stinger seems wrong too. I think he sent the wrong pipe.

I have tried contacting him, no response and he was right there to respond when I inquired about buying one. I did pay through PayPal so maybe they can help.

I didn't have much choice. I haven't seen any other options out there for a 79 DT125. I tried Dogster, no luck there.
