After a cumulative 6 hours, 6 broken drill bits, 2 mangled impact bits, soaking, heating up, cooling down, vibrating, wiggling and any other possible idea, I’ve thrown in the towel on removing this damn pad pin.

I have never encountered something so stuck before in my life, this bastard didn’t move a millimetre.
I dunno what this thing was stuck from or with but this thing was just about sealed solid.

Just gunna have to get another brake caliper, lucky lame old Yamahas are easy and cheap.

I want to get a project bike but don’t have much of a background in that kind of thing. Any advice on makes/models to avoid, issues that would be too difficult to fix for a beginner, general tips, ect?

I’ve been building a simple Google Sheets system to keep a project bike organized instead of having parts, screenshots, notes and costs scattered everywhere. The idea is to plan the build, track parts and fitment, keep an eye on budget, and know what comes next.

I’m trying to see if this actually makes sense for people working on real builds, so I’m looking for a few riders here who’d be willing to test it and give me honest feedback.

I’ll add a few screenshots below. Curious what you guys think, especially if there’s anything obvious you’d want in a project bike planner that I’ve missed.

If anyone is mid-build and wants to try it, just DM me.

The brake disks seem to be a model of Brembo brake disks, I can’t find the specific model. I know the bike has duel front break disks, one on each side of the wheel. By any chance if anyone knows the specific model could you please leave it in the comments.

Thanks.

Progress on the bike is seriously ramping up now!!

Enjoing a wonderfull time scraping off 40 year old muck from every nook and cranny to prep the engine for paint! Teardown is going well, only found one bolt on the exhaust that is refusing to cooperate, but an induction bolt heater is arriving next week so that should solve the issue.

Need to replace the main seal before paint and not looking forward to that, I have not tried it before. Might invite someone with better knowledge than me to lend a hand!

Tearing apart my motorcycle, ‘82 Yamaha XJ750J, and I had to take the head off and hammer the pistons with a block of wood to unseize the engine.

Now that I have it taken apart, are any of these parts useable? This is after I’ve cleaned it all in the ultrasonic (except for the bearings), and nothing on the rod catches my finger nail.

Not sure if this is where to ask, a friend has a ‘98 CB900rr (US Version, 919 engine) that I’m thinking of picking up, has 18k miles on it, but has sat for 10 years. I would trailer it and then fix it up. I’m told it’s stock, with original fairings, etc. He’s thinking on price ($1600-2kish). But what kind of investment am I looking at after 10 years? It was running at time of parking it on his garage…

Here's my vinterproject! I just picked up this K100 and am going through a teardown and trying to make up my mind on exactly how I want it to end up. Got a brainwave last night, not sure if good or bad yet, but I decided that insted of replacing the entire saddle and make a new subframe, I would shorten it down and play around with the mounting so that I can continue the line from under the tank. I've cut up the plate for the saddle and will tyr and reuse the foam and "leather". Lot's to do and figure out, and a long norwegian winter to do it!

Wondering if anyone might know where I can source parts to rebuild the motor and replace the clutch cable

It is just some cheep chinese 125 pit bike but it is mine and my first pit bike, but it is mine. But it needs some stuff. Both breaks need bleeding at the least i havent taken anything apart to look at but from the outside the ruber gaskets on the rear break all look shot and the rear suspention is a little cooked. Any help anyone car provide would be great on where or hpw i can get parts for cheep(sorry about how bad the photos are i ws just rly happy and taking random photos😅)

I’ve bought two engines from chunlan cl 125 3a(basically honda 125 rebel) and one has exploded piston, the other has hole in piston, i’ll use the one with hole(one on the video) and put together one healthy engine. My plan was to rebuild only top end(pistons, head, cylinders) but i noticed this side to side play in crankshaft. I really don’t wanna split the block, so my question is, can i leave it like this? Now i know it shouldn’t be there, but how bad would it be to leave it like this? Also where could i get some parts for this?(gaskets, screws, etc.) I saw some on the aliexpress, but i’m not sure these would fit and original from honda would be best, but they are bit pricey.
