600 jet issue i think

9 posts in this topic

Ok guys my brother picked up a 87xr600. It wasnt running but I found out the stator was bad so I rewraped it. Well now when we ride the bike it cuts out then it come back and then out, if you roll on the gas just a 1/4 of the way it runs smooth but as soon as you go further it cuts in and out. I cleaned the carbs but there wasnt anything there but I did notice that the jets seemed lean. The main is 122, pilot is 45, and the air screw is 1 turn out from the bottom. The only thing the bike has done to it is a white brothers slip on disk muffler.

Any ideas would be great

Thanks

Brad

The DJ kit that I am installin now in a XL600R comes with a 128 main in the left carb and a 132 in the right and the needles with the e-clip in the top groove, go with a 65 pilot (stock is 62 although some hgad 65's in em) and run the air fuel screw 2 turns out. Make sure the air box is clean and opened up and the filter is also clean. If you get into raising the needles a notch - make not of the position of the return spring, because you will have to reset it into the same position. NOT fun. I am still in work on mine...

I am hoping this rejet on my XL600R makes as much difference as it does when you uncork an XR650L.
