My son has inherited an Ossa 250 Mick Andrews (lucky boy!) but it has no compression (got stuck on full revs, so re-bore is likely). Steve Sell is going to sort it for me but I need to get the engine out to take to him. As a newbie to bikes, any advice, things to watch out for, or sources of info would be much appreciated. Are any special tools required? Risk of damage (eg exhaust removal?). I've found the parts diagrams and manual online, but it doesn't cover engine removal. Many thanks.
