Back in 2006, before Romania joined the EU (and the roads got improved) we entered the country from Guyla in Hungary and rode roughly eastwards to a rally in Turda. We came out again via Cluj Napojca towards Debrechen and then on to Kosice in Slovakia. A full account of the trip appeared in Cheval de Fer shortly afterwards.

So you will just have to join the Ariel Owners Motor Cycle Club. www.arielownersmcc.co.uk Go ahead and do so - it will be one of the very best ways you spend money this year - or any other year.

Just out of idle curiosity I was wondering which swinging arm frames are the easiest to fit a Sq4 engine and gearbox in to?

I apologise for this response in advance - but the best and easiest swinging arm frame to fit a Square Four engine into is of course the Healey 1000/4 frame.
I sold my swinging arm Square Four kit last week. The argument went "Why do I need a swinging arm Square Four when I have a Healey?" (The swinging arm Square Four kit involved a 1954 swinging arm frame modified to take the Square Four engine).

I have always been a Triumph twin guy but like you I thought it would be nice to have a square four.
I bought a 1958 Mk2, earlier this year. It's lucky I'm retired... it took me three engine rebuilds before I was happy with it! New con rods, big end shells and new main bearings. Pistons and bore were OK. Big ends and main bearing journals were all OK. I had problems stopping oil leaks in the head area but all OK after fitting an Otto gasket. I did reseal all the pipes and fittings on the head at the same time. I had to cut extra keyways in the camshaft sprocket to get the valve timing spot on. There was already a morgo pump fitted. I would never do an oil change with out taking the timing cover off and bleeding the pump. I have fitted and oil filter.
At one point in the summer, I was wondering if I'd done the right thing.... but now I'm happy with the engine, I know I did the right thing. It seems very happy and vibration free at 65 to 70 mph, two up. During a two week holiday, We went to the Annual Rally in Amsterdam and although we took the bike on the back of our truck, we did 800 trouble free miles in two weeks.
I have converted to 12v and fitted an alternator.
I don't want to see the inside of a square four engine for a long time!
I hope this helps.....
