Hi all

I've recently acquired an 86 Kawasaki Kmx 125 and Im trying to get it back on the road. Its been garaged until recently (last two years) where its been exposed to the elements. As a result there's rust rust and some more rust on rims, spokes, handlebars, swingarm and rear shock. The frame isn't too bad but I want to strip the paint and respray.

I don't have much money to put into the project hence why I'm trying to avoid buying new parts. Is there one solution to removing both rust and paint?

I've attached some pics to show the extent of the rust you can also view them here https://www.dropbox.com/sc/on8trk69s9u40xd/jXgQO2w_aY


Thanks

Before that, are you planning on rebuilding the engine that's been standing for a while?

This is my first experience with bikes so I don't really have much idea about what to do first. I learnt how a two stroke engine works from reading online lol my thinking was to start with the frame because in the process of sorting the frame I could take all the parts off clean them and try and see what everything is.

The engine runs but only when I put petrol directly into the cylinder head (I think thats what it's called...the bit that holds the spark plug) so I removed the carburetor and tried to clean it by removing all the gunk inside with petrol after I put it all back it still wouldn't start so this is what lead me to think I should take it all off and have a look at the individual parts.

EDIT-------
The only thing I've done since is take off the air filter, carburetor, and a container that had blue fluid in it. The original fuel tank was rusted inside so when I was trying to get it started I used the fuel tank from my sr50.
-----------
Sorry if I sound like a complete dumbass here but I really havn't got a clue my plan was to just mess around with it and figure everything out as I go I understand I'm probably going to blow myself up but there's not much I can do Sad


Any help figuring it all out would be great Smile

A very firm grasp and a strong up-and-down hand motion.

Wire wool would help.

Sorting the carb out would be a good start. Get yourself some carb cleaner and make sure that all the jets are clear, float valve works, etc.

If its stood still, the likelihood is that you might need to strip the bottom end. They have seals and bearings that, without use, become brittle and fail when you start using the bike again.

OK, seriously, I would suggest that you price up a replacement carb. Sometimes you can find them going for pocket money, and weight that against the time and frustration of trying to sort the one you've got, which could be completely badgered.

So could a replacement, but you know yours is hooky.

I've tried having a look around for a carb on ebay but I can't seem to find any Crying or Very sad Should I try getting a new one/clean old one before trying to do anything with the engine?

Also I noticed that the kill switch was disconnected could this be stopping the engine from running?

As I said on the phone, I'm pretty sure the connections going to the killswitch would have to be bridged, as the killswitch completes a circuit.

removing rust is most easily done with electrolysis.
Removing paint is easily done with paint stripper. (although I have heard they have had to removed an ingredient due to adverse environmental effects and paint stripper isn't really that good anymore).
if that bike was mine I would leave the good paint. I would remove the light rust with wool and some good wanking motion. The heavier stuff I would see if it would be worthwhile setting up an electrolysis tank. I would then touch up the exposed bit of metal with some rattle can paint.

That would have to be some size of electrolysis tank to take even part of a bike frame, why not use a wire brush mounted on a drill? that would take off both the rust and paint and leave a bright surface to start over with primer and paint, why does stuff have to be so complicated?

Well I wire brushed the frame the other day and it didn't look too bad so I probably could just paint the individual areas. The rims on the other hand are probably 100% covered but I'll give them a go with the wire wool once the engines sorted Very Happy

I'm doing some electrolysis this weekend, I plan on using my wheelie bin as a container as it's the biggest thing I have.

this is what I did. I could have used the wire brush and drill bit but there was a huge amount of rust on this bike in particular. would have been there forever. As the bike was stripped down it was easy enough to fill up the wheelie bin and leave it going for a few hours

Ignore the spokes, #0000 steel wool will have the rims looking like new.
