WB E-series Pro meg

[erichsen18]

I have a stock 2002 400 EX and i was thinkin about gettin a complete series exhaust and i was wondering if i should being i only have a stock quad? I know ill have to change jets so what do you guys think? 155 main jet and 42 pilot? will i have to move the clip thing at all? Is that the only changes ill have to make?

If your quad is stock, and you plan on leaving it stock, only get a slip-on. It's not worth th extra money for a stoc engien. But if you plan on upgrading to a high comp piston or anything, then get the whole system.

well my quad has recently started smoking when revved up so i think it will be needing a rebuild after awhile and i wsa thinkin then of goin to a 416.

I wouldn't go with the pro meg enless you plan on more mods like a bigger carb, cam, and bigger bore. If you are staying closer to stock go with the std. e-series set-up.
