I Have a WR250F 2002 I have taken out snorkel,airbox lid &baffel out of exhaust..will I need to richen air/fuel jetting under the carb?..Which way is richen jet clockwise or anticlockwise?................ Also are Unifilters better than stock Is there any increase in power? .... Thankyou..
You will probably be fine with the standard jetting if thats all you've done to an Aussie one. When I took delivry of mine, they actually put a 168 main jet in, and stock is a 170 I believe. If you go for an aftermarket exhaust, then you will need to re-jet.
With mine, it was spot on with standard exhaust & 168 main and all the crud removed from the airbox/exhaust etc.
