Hi guys, i'd like to get hold of a cheap but functional 4 stroke engine to really just rip apart, rebuild and learn on the way, perhaps just trying a few things to it also. Ideally it would be OHC.

Now I'm curious, I'd like to fire it up once I've rebuilt it is tehre anyway it can be fired up on a bench with just an external fuel supply and what would I need electrical wise? The original loom I guess?

Appreciate your advice.

Kind regards

just go for a little single cylinder carbed like from those shitty chinese imprt 125's, can probs pick them up real cheap as the rest of the bike gives up waaaay before the engine (as i found out), in fact you could have mine if you wanted it, been sat in my garden for bloody ages doing nothing

I suppose an air cooled motor may be easier as less to worry about if you do want to try and run it afterwards.

A squirt of petrol direct into the carbs should be enough to get some fuel into the system to fire it up.

There should be plenty of cheap engines off of ebay and the likes, or what about a cheap Chinese pitbike engine?

I had the same idea as you but was thinking more along the lines of a minimoto engine as a little smaller (obviously) and less to lug around. I still think the wife would have thrown a fit if I'd done it on the dining room table though.

i would go for a whole bike. reason being you will have the coil, tank, wiring etc etc there already and an engine fired up on a bench wont be on the bench long if it isnt clamped down tight.
a knackered pit bike would be ideal.
the last motor i ran on my bench was an 18cc strimmer motor. i had to clamp it in my vice Thumbs Up

certainly appreciate the offer may take you up on that if I could sort delivery out.

Yeh definitely thought simple like an air cooled of some kind.

My initial dream was (still is) to get a ZXR 750 engine and strip and rebuild that do a few tweaks then drop it in my zxr frame, at least I'd have a use for it after I had opened it up.

But moneys very tight at the moment since I've xferred jobs and it won't be till the new year till I get my hands on a ZXR engine but frankly I can't wait that long to get my hands dirty so thinking of something cheap and cheerful just so I can piss about with on the winter nights. Tv's crap at the moment anyway and it gets me out the flat.

I too had visions of laying out a sheet on the bedroom floor and stripping it down but then realsied I'd be shot for it. Luckily missues dad's got this big warehousey, garage thing with lights and electricity he doesn't use. Oh and it's just a few yards away. I'm game.
