Engine Building


South Devon Classics engine rebuild service caters for all types of engine. From single cylinder two stroke engines to multi cylinder four stroke superbike engines, we can undertake all types of engine work from a two stroke top end rebuild to a superbike cylinder head reshim or complete strip & rebuild.




Single or multi cylinder engines, rebores, crank rebuilds & crank bearing & seal replacement. When rebuilding older two stroke engines, we try to use NOS ( new old stock ) parts wherever possible.





Single or multi cylinder engines, cylinder head reworks, valve clearance checking & re-shimming. We carry out compression testing & cylinder leakage testing prior to any work commencing on any four stroke engine. This gives an indication of the general condition of the engine.





Moto Morini 350 V Twin engine. Owner had drained the oil during a routine service to find large pieces of metal & swarf in the oil..

Engine was brought to us for stripping to see where the metal had originated from. On dismantling the engine, it was found that the left hand crankshaft bearing had disintegrated. No idea where the missing ball bearings have gone!

Honda TL250 engine circa. 1973, imported from America that is going into a period trials bike. Engine had a snapped timing chain & the cylinder head was full of "Idaho" dirt. Miraculously no valves were bent but they were stuck in the guides. Engine has been completely stripped, head refurbished, new piston rings, seals, gaskets & engine covers repainted.

The completed engine ready for collection.

Honda TLR200R engine that is having a "big valve" cylinder head conversion. Inlet valve size is up to 32mm so valve to piston clearance needs to be checked & piston valve pockets may need deepening.
