Yamaha 225dx pipe and brake lever help

[motoman011]

I have a 1984 225dx that my son has been riding, it's all there except for the front and rear levers, can anyone help me with what levers and perches will work? I have new front and rear brake cables for it just not sure what levers to buy. Dennis Kirk has replacement levers but the perches are missing so that won't help. Second, he'd like it to have more power and sound cool, so I'm willing to buy a DG RCM pipe for it. Anyone have experence with these? Stock jets are still in the carb (112.5 main) and the rest of the settings are stock also. Any ideas on jetting the Mikuni VM22 carb and it going up one full size on the main will be enough to make it run good and not hurt the motor? ANy help would be great.

Thanks for your time
