Zed thou restoration restarted
Posted: Sat Dec 22, 2007 6:34 pm
I have now finished (almost) building my new office and workshop so I no longer need to drive into the filthy smoke (Bristol) to work.
I have worked my arse off since July so now it's time for some Zed play. I've pulled the lump out, and am nearly finished stripping the old girl down to get the frame and bits powder coated. The tank and plastics are going off for painting. I've already taken the head and barrels off. She has a Wiseco big bore kit (approx 1050cc 1mm oversize) as I have previously mentioned on here. The pistons are as new and haven't even horn of the machining marks. They are however not a very good fit in the barrels! The obvious solution is to have another re-bore, but it seems a shame as the pistons are perfect. Perhaps I should keep my eyes open for a standard size but worn set of barrels and have them bored out properly? I've bought a set of new Wiseco rings, but I fear that I may be pouring good money after bad. Had the bores glaze busted but I am now fearing that teh old girls might still continue her bad habit of smoking! The valve guides were shagged and I have had them replaced at huge expense. I had bought another head before the building project started, but after spending a mint on having it vapour blasted, it transpired that one of the valve guides had been very badly bodged, leaving the valve running on the piss - bloody flea bay! There were also crack between the valves and plug holes and whilst I could have the guide sorted I think I'll concentrate on the bikes original head as this seems in much better shape. After my initial experience of vapour blasting I'm not sure that I like the level of glass and allied crap left and think that I'd rather have the engine slightly dirtier on the outside than me left with ground glass in the innards. Any ideas for cleaning the grubby engine without vapour blasting? Tried little brass wire wheels in my dremmel, but these seem to leave a thin coating of brass behind - presumably a big wheel would be worse. This year I invested hard cash in a little Clarke parts washer from Machine Mart and bought a gallon of the prescribed juice for it which is dilluted with water. I cant say that I've been overly impressed with the results. I have found that my original method of squirting IPA on the part and wiping with a rag seems more effective - anyone any thoughts on this?
I'm struggling the get the dynamo rotor off. I remeber I took the rotor off my old A2 years ago and I have a feeling that I used a big bolt as a puller, but so far I can't put my hands on a suitable bolt - anyone know what thread it is? I could cut one in a bit o bar on my lathe if I can put my hands on one. All this hassle cos a bit o dirt jumped down in when the barrel were carefully lifted - I was well carefull, with Henry on standby to catch the shit before it dived down, but even Henry can suck that quick! I guess it's not a bad idea to see what state the innards are in while I'm at it - anything to get out of bloody Christmas .. Bah humbug!
To those who like Christmas I wish you a good time and to the rest of you, look on the bright side, another week and it'll be over for another ... five months?
