Honda-SOHC

YAHOO! I GOT IT OUT! and I didn't even sacrifice a virgin ( not easy to find here in Essex anyway )

I think I was lucky but it was in there very tight. heres how it went just in case it helps someone else. I soaked overnight in penetrating fluid, a quick tentative feel with mole grips showed it to still be 'somewhat stuck' I purchased a 'Professional stud extractor set' ( their words not mine ) from Halfords, Machine Mart do the same thing. These are devices that look like large spark plug sockets which have 3 eccentric doobreys ( sorry to use a technical term ) inside which grip the stud, the more pressure you put on the tighter the stud is gripped. The 8mm one can just be fitted over the stud in question, it is a VERY tight squeeze and I had to tap it on just slightly bruising the the fin below but nothing to worry about as it won't be seen. I applied heat with a blow torch attempting as far as possible to heat the alloy rather than the stud applied a little candle wax then on with the extractor and with a bit of fiddling out it came, I couldn't believe it.

Not sure the wax made any difference but I had seen it used in a u toob vid so I figured it couldn't hurt. I found the head fin below the stud tended to push the extractor slightly off line so at first it didn't want to grip but with a bit of fiddling and pushing it against the fin eventually it did.

Anyway I am off to the pub to celebrate

Thanks Mick, yes, got it from Oxford. Strangely I went to look at the 550's he had but the F1 rang too many bells and I had to rescue her. She is totally original except the exhaust. Spookily in 1976 I went to Costins Honda in Southend looking for a secondhand 500 and came out having bought a new yellow F1. History repeats.

Will have a go at the stud, all the others are fine but am not going to lose too much sleep over it, am looking up 'spark erosion' even as we speak 

Hi all, as per my entry in the new members forum heres a pic of my barn find project F1 ( provided I have attached it OK! ). It has low mileage and has been standing since 1985. Pic makes it look a lot nicer than it is, all the chrome items are shot  paintwork is very nice tho.

First snag, exhaust stud has sheared while trying to attempting to remove exhaust. I soaked all nuts overnight in releasing fluid but such things are bound to happen on a bike that has been standing so long. Anyone removed one of these studs successfully? I plan to try releasing fluid and mole grips while applying heat as I assume it is a steel stud directly in alloy, sound like a plan?

Hi all,

An ageing 'born again biker'from Essex UK here. Old enough to know better but despite that have taken on the restoration of a yellow 1976 CB750F1 ( the exact model and colour I actually had new in '76, ah you can taste the nostalgia! ) This beast is a low mileage ( just under 6,000 ) 'barn find' Basically all chrome parts are rubbish so if anyone has anything including nuts & bolts that are in very good nick, from fork legs to chain guard, anythijng to reduce my bill at the chrome platers and get it on the road as soon as poss coz basically I can't wait! contact me please with pics and price.

Any advice / common probs with this kind of rebuild gratefully received ( like how to clean the crap out of the fuel tank without rubber arms )

cheers for now!
