Honda-SOHC

Hi Mike & Paul, Thanks for the encouragement, but I am still very reluctant to open the motor as I don't really know what I am doing and wouldn't know how to recognise problems if I was looking at them.  For example when Trigger advised that new rings and a cross hatch might sort it I had to google 'Cross Hatch' to find out what it meant.

When I changed the valve guides that was under the very close supervision of my brother, and it didn't solve the oil burning issue anyway.

I have owned the Honda for the past 33 Years, for much of that time it has been my second bike while I had a string of more modern bikes which were my regular rides.  The Honda has been off the road, but maintained for ten years (or more). Last August I sold my MT01 having decided to get out of biking while I was ahead.  I couldn't sleep the night the MT01 went as is was the first time in 46 years that I didn't have a bike, (big mistake I thought) then I realised that in fact i did have a bike - The Honda.  I got up at 6 am and the bike was running by 10, insured by 11, and MOT'd by 12.

Anyway the long and short of it I want to get the Honda working well and reliable, and I have little in the way of mechanical aptitude, I've read every CB500/550 related post on this forum and think I know who I am going to ask to book it in for a refresh.

Many thanks Keep it coming

Hi.
Mine does exactly the same knock when the forks fully extend.

I would like to make it stop.

Hi Trigger

The bike has done 38,000 since new. Some of those on low oil way back when I never imagined I would care about the bike in 2016.

I had thought that it probably would benefit from a short engine refurb but have no idea who to trust the work to.

Regards Rob

Hello, I'm new here.

I live in near Nantwich in Cheshire and have owned my CB500 four since 1983, it has started to smoke, it uses about 1 litre of 10/40w oil every thousand miles, although it seems to run just fine.

I replaced the valve guides about 15 years ago in the hope that would solve the issue - it didn't.  It has not really matterd to me until now, but this bike is my only remaining bike and I want to start to use it as a regular (reliable) ride.

I'm not a very confident mechanic and so I was wondering if any members know of a good engineer preferably in the Northwest that could do some work; likely to be a rebore on the bike.

I have put up a Video on YouTube of the symptoms that may be of use.

Any thoughts or suggestions would be much appreciated.

Thanks Rob
