This is Jetting information obtained on the MIG Forum website. This is only here to serve as a guide. Your Marauder will require different jetting depending on your location, exhaust pipes, etc, etc. But it gives you a good idea on where to start jetting. We are not responsible if you kill your Rauder. Stage 1: Adjustable needles and set the Mixture screws. Stage 1.5: Adjustable needles and set the Mixture screws.

Removed tank and carbs. Rejetted w/95front/105rear, placed 2-#4 washers in place of the plastic one on top the jet needle, 2 washers equaled half the thickness of the plastic washer. Reassembled everything last night and she fired right up. Runs great w/the mixture screws set at: 2 1/4 turns out. After clocking 25 to 30 miles I know now I was definitely lean. Rolling on the throttle and she just steadily pulls strong. I did remove the snorkels from the air boxes as well. -------------------------------------------------------- Mutant's Marauder 2002 Marauder Stage 2 Jim's Kit 122.5 front/132.5 rear mains SU-5589 K&N's Stock exhaust ---------------------------- Rogue's Marauder so far running spacer jim's stage 2 125/135 main jets su-5589 k&n filters stock primary's Web race cams got to change the springs (vesrah's in the mail) and going up to a stage 3 when i can find the right filters Jims screw kit jardine slash cut rumblers ------------------------------------------------------- Eric's Marauder 1999 Marauder (Green/Black, the fastest colors) Spacer Jim Stage II Kit SU-5589 K&Ns 125/135 main jets 42.5/47.5 pilots Cobra Slashcut Slipons -------------------------------------------- Skier's Marauder Stage 2 Jim's kit 122.5 front 132.5 rear clips at 4th notch front, 3rd clip rear stock pilots SU-5589 K&N's stock exhaust drilled out, stilled baffled Vesrah clutch springs 16T front sprocket ----------------------------------------------- Dennis's marauder 2000 Marauder spacer jim stage II 127.5, 137.5 stock pilots 3rd clip front, 4th clip rear, a/f screw 2 1/2 truns out.

I know others run larger mains than mine - but my ride seems to run a little rich, even at these sizes. ----------------------------------------------------- Comments: Stage 2 with debaffled or stock pipes start with 122.5/132.5 main jets with your stage 2 kit. With slip-on pipes 125/135 main jets With 2 into 1 pipes 130/140 main jets ---------------------------------------------------- Stage 3: With slip-ons I'd start at 135/145 main jets. With wide open drags about 10 points more each. Of course this is just a starting point.
