Drz rebuild. High comp piston or standard

[flits84]

Hey guys I've got a drz400e and I've pulled it down for a freshen up but wanted to get your guys opinion if I should replace the piston with a factory one or a high comp? Any benefits or downsides to either?

The standard is high compression 12.3:1 if I'm not mistaken for a factory E model.

the generic answer is more compression creates more signal and flow and by deduction conceivably produces more power .. the downside is the risk of detonation is higher so you have to worry about top quality fuel or additives .. i'd stick with stock, its got the stock ratio in there so the average cletus cant mess it up ...

I don't know this as fact but I've read on the quad site that anything over 13.1 requires race fuel in this motor.

ok guys so in that case ill stick to the stock 12.3:1 piston. our premium fuel in New Zealand is 98. Being a E model it already goes great and id like reliability more than anything
