Lisa engineering is a nightmare even to me i had bikes all my life, the bike in my avatar i touched every nut bolt on that bike even the engine i striped it down to the bare cases and re built it with a lot of help from my mate who was an aircraft engineer and worked on the A380, it's a nightmare to ordinary people like us but you will get there in the end, i did get one over on my mate he had just rebuilt an engine a 500 v twin he asked to come over to put it back in the bike, while he was making a brew i thought for no other reason to turn it over i put a spanner on the on the camshaft nut and turned half a turn and clunk it lock up solid, it turned out he had put the pistons in wrong left in right bore and vice versa he was very thankful, hang in there Lisa you will get there
