grizzly 600 carb, going back to stock jets
I have a 2001 Grizzly 600 and last winter I put on an HMF Utility slip-on exhaust setup as my stock muffler rusted clean through. I had the so-called "silent core" for it (ya right) and the thing was just too loud for use. Well anyway, when I put it on, I also put in a dynajet kit which upped the main from i think 42.5 to something like 85 (can't remember right now the exact but it was what i considered a pretty big jump). I also put in their upgraded needle and the k&N air filter.
Here's my question. I ended up buying a new "OEM" muffler for the bike and put it on in place of the ridiculously loud HMF setup but I still have the k&n air filter installed and plan on leaving that in. Would I be right to swap the main jet back to the original stock size of 42.5 now that the OEM pipe is installed? Also, if I do go back to the 42.5, would I be able to leave the upgraded needle in there or is that going to cause issues? I basically just want a stock setup with the K&n filter but the way I understand it, the stock jetting is based on the needs of the stock exhaust and air filter setup? Anyone have any insights on this? Thanks
