I am trying to find something that has been proven and works on my sons stock ds50.I am not looking to re invent the wheel and hurt reliability etc.I have removed both air and exhaust restrictors.I am looking to order the cdi next but not sure what one to order as I have seen mixed opinions,I would like to get a plug and play one (dont really want to cut wires etc) ,can anyone confirm that the ds90 cdi is the same as say a aftermarket one?Also does anyone has the jet specs for the above basic mods?I have not checked the band between the clutch can someone confirm that all years had these?Also what gears have you guys found to be a good over all for slow grass and dirt riding and trail ridding etc?

Thanks
Brian
