Hi
Posting on behalf of my son as he is too young to be on these sites etc, anyway we are quite new to bikes and more into mountain bikes if anything. Anyway, bought a 2nd hand Norco Nail for my son as he wanted to do more jumps etc and told him no to doing it on his expensive MTB! The bike is in real good knick etc, looks like very little use, 1 question I have though, not understanding how bmx work (gear ratios etc), when you pedal it, it (pedals) seems very stiff/jerky until you get them moving faster. The chain is very tight and no slack in it at all. I'm assuming that is the problem; the chain needs to be loosened of a bit ? But I'm getting mixed messages on reading up on it/videos etc. How much slack should the chain be ? Or could the problem be in the pedals/bearings/cranks area?
BTW
Many Thanks
