I recently got the team suzuki yoshi for my son's 250.We installed it ,let it warm up and tested it around the neighborhood. The motor had a lot more responce and sounded great.Their wasn't poping or missing with the new pipe.My neighborhood shop say's that the team suzuki series is made to run with the stock set up .Should I leave it alone or jet it,If I jet it what jet should I use.[img]i/expressions/face-icon-small-cool.gif[/img][img]i/expressions/face-icon-small-frown.gif[/img][img]i/expressions/face-icon-small-confused.gif[/img][img]i/expressions/face-icon-small-frown.gif[/img][img]i/expressions/face-icon-small-cool.gif[/img]

 

Full pipe=Jet......Slip-on=good to go! Do a search on here for z250 pipes and you'll learn.

 

As was said in the other thread about this...

Any time you increase the flow of air threw the engine, you need to rejet the carb, or it will run lean. Before you rejet you might as well put a better flowing filter on the bike that way you'll get a little more power, better filter, and will be more worth while to rejet.
