New rider concerned by sprocket nut problems!

[limax2]

My front sprocket is done up tighter than my wallet :'(


Breaker bar and still not coming off, any suggestions or i'll have to cut it free! :eek

I don't know if anyone has ever damaged the gearbox by using excessive force, but for the cost of a new nut I would be inclined to split it if it's that tight. If it's held with Loctite or similar (as it should be) heating it up will break down the Loctite but you then risk damaging the oil seal.
