Honda-SOHC

A lot of people's don't like the PD carbs and just base it on getting them going if the set has suffered no use and things have got gummed up.

I think they are the right way to run an engine and offer an advantage over the older types.

They don't run lean as such,  just closer to optimum for an engine to be efficient while adding extra fuel just under acceleration. Just when it's needed in other words, and not rich all the time to make the oil diluted with unburnt fuel. Properly cleaned and setup they're good carbs and no reason not to use them.

The valve guides for F2 are well covered on here.  Honda seemed to have stretched a little too far on this aspect, but if you've not got them then it'll not give you problems in that area.

I think I will attempt to use them when the time comes K2. They are in mint condition. I think it's time I moved over to the cb750 link before the moderator comes calling as my introduction has gone on long enough.....Thanks again.....Frank

Thanks for that Hairygit. The guy who looked at it confirmed the same. He actually said the inlet ports on the F2 are bigger than the K's and that the F2 carbs run lean. So I now have a set of spotless F2 carbs that have been serviced and vapour blasted that I can't use, great start.

Nothing gets thrashed anymore at my age. I wish it did. Thanks for that.....Frank

Attached oil filter pics. Am I right in thinking if I was to purchase a std oil filter bolt I could disgard the sandwich plate? What issues might this have? It looks quite hideous on the engine block (boil on the end of it's nose) don't like it! I am going to strip the bike as light and as naked as possible, what do you think?

what a nightmare, trying to get the engine out. Having digested most of the posts on this subject and reading manuals I tried and tried to get the engine out as instructed. I eventually had to remove the exhaust studs and she came out easy. On inspecting the studs some were just threaded bar and I'm thinking these cant be original. Anyone know how long they should be. I'm also a bit confused about the oil filter housing. When ordering a new oil filter for an F2 they only show one large o ring along with the small one for the bolt. I have the housing for the filter plus an extended housing that has vents. This too has a large o ring. This secound housing is not shown in the Haynes manual so I'm confused as to what filter I need. Any help would be appreciated.

Thanks for that guys, I'm still waiting for the V5, so should make interesting reading. I must admit the wheels through me out as well

Yes Dixons it is. I'm just outside Filey at Hunmanby Gap down by the beech. I've just taken some pics. Can anyone confirm the model. Ive also include my Yamaha triple xs750 before and after.
