    If you have exhausted every change on the chassis then you could move your seat. Even moving it a centimeter forward or changing the angle of the rear of the seat can greatly change the way a kart handles. If you are struggling to get it to turn, I would move the seat forward a bit. But go back to your baseline settings on the chassis after you move the seat–then you can check to see if it was the seat move or the chassis changes that fixed or made your problems worse. Remember to only make one change at a time.

    *disclaimer* I am not a MARGAY specific tuner but I did stay at a Holiday Inn Express a few years ago. And I might have been around a few karts over the last few years.

    Thank you Kirk for the recommendation. I actually did move my seat up when I got a new seat a few races back. It did actually help out a lot and going back to baseline setup did help but still slow. Still too much grip with even the baseline. My last change was to go to a harder axle which definitely got the rear end to get loose on Duro’s. This in turn allowed me to add more front end grip. MGs it seems to still be too much grip in the rear. I usually have to add seat struts and widen out the rear. I can’t get rid of the push in the front without putting too much grip in the rear. Hopping and a front end push has been my number one issue from day one with both sets of tires. As you can see running two different sets of tires this season as totally got me all messed up. lol I mean I write everything down and have it all logged. My problem is I make one change and it fixes the issue slightly and then I mess it up again on my next change. Then I go back to what felt good and make another change and it feels good so I keep it. Then continue down the path. I just seem like I am lost. Maybe I am right there and the latest changes need slight modifications. Maybe I have “lost” the feel I need in a good running kart? Granted, I am only a year old in this sport and purchased a well setup kart for my first kart (ItalKart, that I only widened the fronts on all last season.). Buying a brand new kart that not a lot of people know much about it and being new myself was not a good choice it seems. lol

    Sounds to me like you should move seat and/or change seat compounds (yes, again). When we work on a new type of chassis or work with a new chassis brand we typically move the seat 4-5 times before we get it right.

    Call Margay and ask for the recommended seat specs.

    The only Margay I have worked with is Tim Trostel’s, and we had two different compounds of seats and ran each one in 2 locations before we found something we were happy with.

    I was afraid of that Greg. lol This seat is a nice seat from a comfortably standpoint but I have a feeling it is too soft or has been a lot of my problems. Is that what you all are talking about? Is moving the seat forward reducing the flex or something? Just trying to understand what the seat actually does to the kart. Keep in mind this seat is different than what Margay recommends. I picked the seat for other reasons. lol I think that might have been where I messed up?
