--- Quote from: Spitfire on December 23, 2009, 09:21:43 AM ---As Bryan says, the F2 motor was the most powerfull SOHC CB750 motor, the bottom end is bullet proof and it's only the valve guides that are dodgy. Like all the CB750's they need regular oil and filter changes but apart from that they are very reliable.

What about availability of parts such as valve guides. Again have read comments about spares for the F2 motor being hard to get. Is there an option on uprated / higher spec valve guides.

Also and off on a tangent -  did F2 come with electronic ignition as standard or was this the last of the points models?

UK Pete:
The parts for the F2 are getting harder to find, for example pistons ,rings and valves, i would say the fact that there are plenty of them still running and on the road would suggest they can last, apparently the valve guides are the first thing to wear out, but are easy to replace and still available, also the valve tips can take quite a beating the fix for this is to instal lash caps, nearly all engine parts for these black engined F2's are available, dynoman & cycle x in the USA make piston kits, ss valves, springs , cams ect, if you look around and have a large wallet anything is possible, i am rebuilding one at the moment , i dont expect to do more than 1000 miles a year on it so once rebuilt it should be good for a long time, you have to remember that k models also have there problems its not as if they go on for ever with out anything wearing out, but the production run was long so parts are a bit cheaper, and easier to get in some cases.
I have 14 bikes and if i go on to any forum there always seems to be negative coments about any one of them, i think there is nothing better than to make up your own mind , my opinion of the F2 is it is the last and the best of the sohc Hondas and a fast appreciating classic,  i may change my veiws when i have finished it , if a k model came up for the right price i would also like to own one of them one day. oh yes the f2  have points, but aftermarket electronic igniton is available still

I agree on the future classic thing. Buy now while you can.

A good (gold) K2 will cost you
