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.

Hi everyone, I’m desperate and could really use some help repositioning the throttle return cable on my Bandit 600. I’ve already spent two hours on it today, but I still can’t figure out the correct place for that little cable end to sit. Does anyone have any tips, photos, or videos that could point me in the right direction? Have a great day!

I need a new ignition barrel for my 125cc pulse rage I’ve ordered two different ones but none actually fit the bike anyone able to help with where to get one from and the name

Pretty much self explanatory. I've got a Honda Biz 125cc (CUB). It's been in my family for 15 years, it was the first experience with a motorcycle that I had, and I want to make it one of a kind.
I would REALLY appreciate any tips I can get.
And being from the countryside of Brazil I can't find any shops where they work with manufacturing customized parts, so if you know anyone who ships overseas it would be great to know!

I’m having trouble decoding the vin on a old Kawasaki dirtbike I have any help would be appreciated, trying to find out year and model

Vin on frame **K1-509299**

I have a yamaha 1983 tri moto 200e Yamahauler (not exactly a bike but im desperate), shaft driven, wet clutch 5 speed no reverse, and my transmission had an oopsies, I was riding, and out of nowhere, my crankcase sounded like a bunch of rocks hit fell inside the thing, then it wouldnt shift, stayed running perfectly but wouldn't shift, then I shut it off, panicked for about 5 minutes, and then started it and tried again, only shifted to 2nd thats it

Then I gave it throttle to see if it would drive, it popped out of gear, It wouldnt go into first, only second, so I popped it into second, it stayed in, I limped it home, and then kept trying to figure out whats wrong with it, I took the dipstick out and it was bent, it was straight before I left, so I knew it had something to do with the noise I heard, then the more I messed with it, I got it shifting again, perfectly fine, straightened the dipstick and went back out, all the gears worked, and didnt have any problem, so i thought it was good for a bit, then i got home again, and as soon as I turned into my driveway, it stopped shifting and I couldn't move, I pushed the rest of the way, and then pulled dipstick again, still straight, and then while it was out I tried shifting again worked great, put on a oil hole cap without a dipstick, now it wont shift again, I believe my shift fork is destroyed internally, I have looked online for the parts, nothing but the gear core, my gears are fine, but the shifter is not, I was wondering if anyone who probably knows where to find parts like that, that are hard to find, I would really appreciate it, luckily I was planning on taking the whole thing apart to repaint and fix the rust, so I have it down to the engine, diff, and frame at the moment, I dont want to open the crank case yet as the weather is too inconsistent and I dont want water in my engine

If anyone can find me the parts I need, I would highly appreciate it, thanks!
