Supa 5 Engine Rebuild

[andy288]

Any idea on competent person(s) to completely refurbish my Supa 5 engine - I'm in the West Midlands?

Anyone fancy it?

Try doing it yourself, they really are straightforward engines, a haynes manual and the official MZ manual in conjunction would see you fine (i have a pdf of the MZ manual and parts fiches if you need) and a decent set of hand tools.. only specialist tools required is the clutch puller.. cheap enough to buy.

?What about the UChannel tool for splitting the cases? ?Unnecessary?

I have the proper manuals with dimensions for everything, even a block of wood for supporting the piston.

I have scanned the pages so I could upload them if they would be useful to anyone.

Never used one in years of working on MZs. ( I have now got one somewhere that I got given when I bought a ES250/1 outfit form Germany... God knows where it is though)
Remove all the screws.( Are there 13 of them? (it's late and a while since I did it!) knock out the dowel at the front of the crankcase.Then I would play a Paint stripper hot air gun over the main bearing until I got bored and use my favourite tools, a old butter knife ground to a sharp edge and a hammer and tap round the crankcase until the cases parted enough to use a pair of tyre levers to totally remove the generator side case.

With practice I could split a Supa5 engine , replace all the bearings and seals and rebuild it over a weekend ( well it was that or not being able to get to work on Monday!). Follow the book, take it easy and they are a very simple engine to rebuild

Take your time do it correct...and tidy
no thrill like having your old daily driver everyone makes fun of
be the only bike that makes the weekend ride and not break down

i think the reason the english guys like these old 2 smokers .
is fix it right and do not abuse it and it works good for a long time

it can not be the gas mileage as every 2 smoker i ever had was a gas hog but they were 305cc and up
