Is it overheating while riding? All 450's overheat idling on the stand.
Yes, while riding. I put a 180 main and the spark plug looking very good plus the overheating in f.o.t. stopped. Maybe i must change the needle 1 clip up. I open the right side of engine ang the water pump cover to ensure for leaks. All good. Maybe the opened boot of 2012 and the twin air filter acts deference from 2006 to the mix. I check the spark plug tonight again. But with 45 pilot and 2 turns, the idle are stable now with no b.f. thnx a lot.
One more, i have all the stock jetting of 2002-2008 X and R models 250 and 450. If anything gonna help anyone just show my the way
