    Marks 4-2 made my A/F ratio rich?

    I added a Marks 4-2 exhaust with the 14" cans and had my bike dyno'ed to see what adjustments need to be made. The dyno chart shows me very lean at idle then rich from about 2K all the way to red line. My A/F ratio from 2K up is around 12-1 I would have thought a better breathing exhaust would...

    Going to buy Marks or Holeshot

    I listened to Marks Pipes and Dale Walker Holeshots on the web. Without hearing both in person, I think I like the sound of Marks better, but I like the look of the Holeshots better. I am not sure which system would give me the best horsepower increase, but that's secondary as I'm already...

    Marks Pipes + something new? Marks baffles

    Recently, installed a Marks 4-2 stainless steel exhaust with 14" mufflers on my stock 06 w/o any problems. (Thanks to you Mod Monkey, it?s not stock ANYMORE !!) Made the recommended changes: 1) set the A/F screws to 3.5 turns out and 2) shimmed the carb needles to 0.038? (used two #4 steel flat...

    Center Stand and Marks Exhaust

    When I bought my VMax, the center stand had already been removed by a previous owner. I missed having it for a number of reasons, which included checking the steering head bearing tightness. I had questions about installing a Marks exhaust and then installing a center stand. CaptainKyle came up...

    Additional Parts Needed To Install Marks Exhaust???

    My Marks Exhaust will be in Thursday. I'm fairly sure I need exhaust gaskets. Don't think they will be supplied. Mark said something about springs. What springs might he have been refering to? I was so excited to actually speak with him and make the order, everything flew right over my...

    Kerker vs Marks 4-2-1?

    It's been a long time since I've heard the Kerker and never heard Marks exhaust in person. What's the difference in sound/volume between the Kerker and Marks 4-2-1? Thanks

    Has anyone run Supertrapps and Marks on the same bike?

    Hey All, Now that I've got my bike to ride like I want it to, I am considering making it faster and pull harder. I know the exhaust in stock form is more restricted, so to fully benefit, I'm guessing I'd need to upgrade to a full system, and then do something like a stage 7 kit from Sean...
