CB750F2 SOHC

[Moxey]

Morning

I'm going to look at a CB750 F2 this afternoon and was just wondering if there is anything in particular to look for.

It's listed as a non-runner, been laid up for 20 years

The bike in question

I'm suspicious that its an import with the late registration (79 onward was supposed to be DOHC) but I still don't think those are original colours? I'm also aware of valve issues with the F models but other than that any specific points to check?

Thanks

Doesn't actually say in the add that its an 'F2'

The Honda SOHC forum is probably your font of all knowledge on these.

It isn't totally original; has ace-bars for starters. AFAIK, all the SOHC 750-fours were 'K' designation, and to the cross-over DOHC model that immediately preceded the FII.

XRW672S, isn't a 1981 registration! 'S' suffix is 77/78, so either an ad mistake, or '81 is the year of import, 77 the year of manufacture.

Add provides very little other info, pictures not a lot more; colour sceme? Doesn't look non-factory, but which option it was for & what market? Probably US. Early pressed comstars would have bee contemprary; twin-disk? I'd not be so sure on; the 'fast-back' euro-styling with abbreviated tail but non integrated tail-lamp, may mark that one out as a cross-over model, or a US regional variant for local C&U regs.

£1000 for one of the last 'unloved' comstar and plastic body SOHC's is a bit on the high side for a resto-base to my mind; restored they are seldom worth more than 3-4K... but, even at a grand, they are a cheap source of parts, broken to restore a wire-wheel model.. unfortunately, though that one could be pretty original bar the bars, and might be a more viable resto.

Did you buy it?

So I went and had a look, turns out its a 78, the 80/81 was a typo (I missed the photo with the reg in ) turns out the owner inherited it along with a vast quantity of bikes (some really interesting, BSA A10's a starfire alongside Jawas superdreams etc) from his father who passed recently and as it turns out used to compete against my dad and his mates in sidecars in the 70's.

No way was I willing to part with more than £800 for it going by the photos less now I've seen it in person and discovered the engine to be seized, going back on Sunday with some tools to check the top end if all seems fine I might make an offer but if its bottom end then I'm going to pass, knowing who the previous owner was I'm suspicious it was raced at some point.

Last October I passed up on a 78 F2 from a friend with a burnt out valve but in otherwise ride able condition, he offered it to me for £800

That was never a popular bike when it came out. Maybe in the states but not in UK.

I seem to remember it being one of the first multi cylinder bikes in mass production with just one silencer. That did not go down well.

The older one was much nicer

To this, in the colour scheme I remember

No contest in looks and it had a cheap feel to it.

So did the comstars and twin front disk come in with that bodywork? This looks different.

I do love old Japanese multis
