Uh, well I can't undo the bolt which fastens my front sprocket. I'm not even quite sure if it's a left or right handed thread (assume left). I checked the correct torque setting, and I should be able to undo it quite easily based on that, but it won't budge. Also, how should i be trying? Bike in gear, rear brake on, rear wheel on ground with someone on the bike? With the bike in gear, i'm just turning the engine over against it's compression... Anyway, please help me, someone! Cheers, Mick.
