Hi All,
I recently bought my first Ariel, a 1958 HT5, so I thought the best thing is to join the Club, which I have now done today. The bike seems to be pretty original, a bit tatty but was running although not very well and not easy to start. I want to check the bike out and do what needs to be done over the Winter so I can use it next year. I started checking obvious things like chains - both totally shot. I found the clutch centre nut was just finger tight, sprocket lockwasher not turned over and other stuff like that. Strangely, all sprockets look good and clutch plates show no sign of wear at all. Anyway, I thought I better take the head off and have a look. Valves look very good and guides look new but there are signs of the exhaust valve either sticking or not been ground in properly.
Piston (+0,020) is clean (the photo shows it as the head came off) and there is no wear at all in the bore, it measures exactly what it should and there is no wear 'step' but what do you make of the black deposits all over the the bore ? See photos. I have not taken the barrel off.
The other thing is - is there some sort of locking device on the front brake plate that I cannot see ? I can't get it off by standing on the rim and pulling the plate and I don't want to unnecessarily force it.

Any suggestions for the best place for spares and any ideas for wheel rims and tyres. I will be using the bike more as a rough trail bike and very low key novice trials - no serious trials and I want to keep it largely in original trim.

The spots look like rust that has been polished over by the piston. Might be worth lifting the barrel and checking the rings for freedom in the grooves as well as feel the big end. Check the front brake backing plate for cracks and corrosion. Nev

Hello MarkC,
There could be a ridge in the liner, turn the tensioner back an try again.
It has signs of being in the water or in a flooded area.

Thanks Nev, Chris and Adrie :
This is great - I can post late in the evening and have answers early in the morning.
1.)I will pull the barrel off this morning, as soon as I check the Cricket score.... If this has been rust it could be worth honing the barrel I suppose while its removed. I had intended to get the alloy castings aqua blasted while they are off to get rid of the staining but I will cap (top and bottom) the bore beforehand.
2.) I'm in the North of England.
3.) The bike does have signs of being in a flooded area and also signs of standing a long time.

Honing's OK but you do remove metal. Marks don't matter much as long as the rings seal. Nev

Check that the barrel has not rusted through from the outside-can happen, mine has.
You need to remove the brake plate anchor arm from the fork to remove the wheel with the brake plate attached. Be aware that the anchor arm is slightly cranked to accommodate the difference btn plate and the fork not being in line. When the wheel and b/plate are re-attached the anchor arm should fit nicely without being stressed, otherwise the plate will tend to be stressed out of line, seems obvious I know. I believe this may be one reason some bikes have suffered a brake plate failure at this point.

Thanks for all that.
I lifted the barrel off and those marks are definitely corrosion (possibly condensation through standing after a rebuild ?) and the black probably burnt oil where the rust spots were. Anyway, now the barrel is off I can now feel some of them so some marks must be deeper than others, I will hone the barrel and see if it helps at all but as Nev said, it doesn't really remove any material.
The piston rings seem fine in the grooves with adequate gap.
I cannot detect any vertical (or lateral) movement in the big end but there is a large amount of rocking movement, nearside to offside (like a propeller). I will have to split the crankcases and check it out - Anything specific or general I should look out for or be careful of ?

I'm in Northumberland Phil, as you probably know it's generally sunny up here although I did buy the bike from 'down South'.
