A factory that makes heatproof paint and it goes and burns down!!!! That's irony for you hahahaha

I am rebuilding an xs500 and painting the engine. Can anyone recommend a reliable paint that will do the job. Am thinking I might need a good black and silver. I heard that some silvers go a bit yellow after they get some use does anyone know anything about that??? Cheers

Been trying the putty knife thing for hours now and am still struggling. I think if I haven't already caused some damage if I carry on I am sure I will. I just spoke to some guy who's number I got of some forum and he said he is 99% sure it dowel pins that have rotted. He reckons the thing to do is to heat the crankcase up as hot as I can then give it a hit and this should do the trick. I'll keep you posted.

That's an idea.. am trying it as I type.

Cheers buddy. From what I can figure out I think its a case of the cement that has been used being a little too effective this time around. I hope someone can come up with some advise to separate them.

I bought a yamaha xs 500 engine recently and am in the process of taking it to bits as it was in a bit of a state when I got it. I am slowly working my way through it and am hoping to end up with a cool looking bike at the end of it. I have had a few problems along the way as I have never done anything like this before. I have worked my way through them but have hit a bit of a brick wall at the mo. I am trying to split the crankcase and it seems to be stuck fast. I have removed all the nuts and bolts as far as I can see. I have a haynes manual as but it is for the A series and my engine is a B. Dose anyone know of anything that I should be aware of or have any tips for splitting the crankcase.

Thanks again. I have myself a haynes manual for the earlier models, which is proving helpful, but I have noticed a few small variations in the workings of the engine. Also the electrical diagram that they have on your link looks like the kind of diagram that would be more useful to me as my skill in that department leave a bit to be desired. So the simpler the better. Electrics are a bit down the line at the mo. Space to work on it is a bit of an issue at the minute so I am planning on striping it giving it a good clean. Think I will resemble it then just to get my head round how it all works and so I am really clear on what goes where. Have never touched an engine before so it all new to me. Have boxed it all and am taking lots of pics... seems all quite straight forward though. Exciting too. might get some work done on the cylinders and the valves (they are stuck fast at the mo) need to do some research there as I did read that the cylinder head had a tendency to crack on these bikes and I don't want to end up doing work that may promote that problem. Lots of big learning curves and am enjoying the process. cheers again

Hey Looks like I have the xs500b too as the 1st 3 digits are 371. Thanks for that. It helps..

I have just bought a yamaha xs 500 engine from a breaker which I am renovating. I was told it was an import but that is all I know. Does anyone know who I can contact about getting more details and info about the the engines history. Also as I understand the same engine was used in the tx. I was wondering if it was used in any more models and what the differences were in specification. I will be looking for a frame and am uncertain which other frames I can use. I am going to make some modifications to the finished bike but wanna try and keep frame and engine as original as pos so its not too much of a mishmash of bits and bobs Cheers
