Honda-SOHC

Hi Pete. Well have moved on a bit since my last post. The cylinder head is now in the hands of the cylinder head shop and when xmas is over I have to get some oversize valves due to the seats needing cutting, also the case barrels and head have been vapour blasted so look great, will be having the cases painted soon (its all money) still have a list of stuff to get like bearings ((roller) and chains and stuff to bring it up to a good motor, but looking at the componets all seems to be in good order. Looks like I'll be fitting a 4 into 2 exhuast system (only becuase allready have) untill the HM300's are in stock with DS if and when they do them. I plan to get the engine up and running via the bench test method first before it goes in the frame as to ensure nothing leaks and oil is getting to all the right parts icluding the head as have had problems in the past (wrecked cams). Not sure if anybody knows if the oil ways in my head are fixed as in the later heads as the head I have is an early 1(short intake stubs) as I would like to take them out and make sure the are clear. The wheels are also away to be respoked (stainlesss) so should be getting them back in the new year. They are fitted with alloy rims I am aware these are not the original but they are what was fitted when I brought the bike in 1980. Anyway all the very best for The new year and hopefully there will be another K0 giving it what for on the roads where they belong. Safe riding all. Chris D.

Cheers Pete. I'll try to get some pics on but have trouble with the file size and no program to squeeze them to 300mb. At the moment things are waiting on bits and pieces and of course dosh. As soon as i get moving i'll get back to the forum hopefully this wont be to long things seemed to have stalled a bit. Anyway looking to get completed around june/july time so better get my finger out. I too have a new set of HM341,s but hopefully DS will come up with the goods at a price we  can afford. Cheers Chris.

Just a quick update on rebuild, frame and swing arm now away for powder coating, engine yet to be stripped and cleaned. Not to sure if I am going to have the cases painted etc but my thoughts are heading that way. Sorry for no posts lately its been hetic and time has been in short supply. Will hopefully get back to the K0 shortly as the guys who are doing the frame are on hols so will post some pics when I pick frame up. take care all. Chris.

Hello top end fixer.

Yep will post some pics when rebuild starts in ernest, just wanted to get engine running properly as always did have idle probs but not so now as utrasoniced the carbs  and balanced ,all new internals to carbs and set floats properly. It now sounds the bizz. When I brought the bike in 1980 (yes I have had it that long) it was all black and would not run as some one had fitted the carb slides the wrong way round. When I rebuilt it in 88 the camshaft had a roller bearing conversion (never seen one before or since) which i ruined due to the too much holymer prob and fitted a later head, I now have a few spares and the original head will go back on when I get to that stage but will go in with all new primarysand camshaft chain and anything else tha needs doing. I have learnt a lot since a while back so hopefully this rebuild will go better and I am taking it back to it original colour which is candy blue green, however am having probs getting fork ears and finding some one who can respray the tank etc. So all is ongoing and cheers all for the info.

Hi Guys.  Just a quick note re ultrasonic cleaner, have recently brough a JPL 8050 from Maplins and bunged in my carbs from my K0... really did work well needed a couple of goes and you can clean 2 carbs in the 2.5ltr tub,its at a good price at mo.. get the metal gleam for best results...

All the best Chris.

Hi top end fixer and cheers for the welcome, yep did use blue holymer on the 88 rebuild and yep plastered it on, so goes to prove to much is not always the best?. Just in process now of getting carbs sorted and came across a few bits in the rebuild kits that are of no use to my beast, namely the air screws that have holes in them and the bike would not idle, so brought a ultrasonic cleaner and cleaned up all the carbs and refitted the old air screws and bingo more or less a perfect idle staright away. Just got to sync them up and hopefully smoothnerss will return (do get a slight pop from No2 pot but it seems to have always done that).

Cheers Chris.

Hello all, just joined forum and as you say all very helpfull, work in Brighton live nr Heathfield. My bike is a CB750 k0 1970.
