Engine rebuild
Posted: Wed Mar 25, 2026 5:52 am
Hi All
My 1098 was leaking oil, the head gasket has blown and the engine had a complete leak of power. I had some work done by a local garage but it wasn't brilliant. The engine still leaks! But the power is still appalling. Travelling up hill I tend to lose all speed and in some cases end up in first gear. I am considering a complete rebuild.
Rebore and New Pistons: To restore compression and stop the oil burning.
Crankshaft Regrind: To ensure the bottom end is silent and reliable.
Upgrade the Head: Fit a lead-free cylinder head with slightly larger valves.
Is there a recommended machine shop that would do this work please? One local to Cornwall would be amazing? I think I can I get the parts from ESM? Is there anything else someone would recommend please? I did consider a 1275 but they are hard to get and I would probably have to do a complete rebuild on that anyway!
Thanks
Rich
