telecat Posted December 8, 2009 Report Share Posted December 8, 2009 Disadvantages are that it does not fit the standard reed block so you need to buy the adapter from a Gas Gas Dealer. You need to set them up as follows Main 118, pilot 42, needle JJH with clip on middle, 3.5 slide. I think that you can also try the 115 Main but that's a good starting point. Advantages are that they run sweeter and pick up faster and with more power thru the rev range. Quote Link to comment Share on other sites More sharing options...
