Re: BIGGER JETTS FOR 25HP NISSAN

Nissan does not offer a jet upgrade for horsepower. Do you have a handtiller or a remote control model? If you have a handtiller model you can pull off the rubber grip on the throttle handle and pry out the little metal block. That will make it a 30 hp. If you have a remote model...its a 30 hp out of the box.

What IOB said, but to be more specific: You cannot increase hp by increasing the amount of fuel unless you also increase the amount of air.<br /><br />Bigger jets would only make your engine run lousy and suck fuel.

There is only the one plate on the 96 and newer models.
