Hey there guys. I have a 98 XC600. I'm one size smaller on the main jets, I have the clips raised one on the needles, I have a B&B stinger and 144 studs. I just installed the RSR boost bottle and now my sled boggs out of the hole. Once I get going, it frees up. What is the proper set-up for these boost bottles. I didn't change the pilots - they are stock - I adjusted the air mixture screw down to 1 1/2 turns to bring the idle down. Help!!! What do I do???? ;)

Ice I think you are still lean on the bottom end. Try turning in the air screws some more. You may have to go down to 1/2 turn or less. Go 1/4 turn at a time and see if the throttle response improves. If you need to go below 1/4 turn open you will have to consider going up a size on the pilots. What else have you got in those carbs (slides, jets, needles)?

Gearhead, I think that it's the opposite. I'm too rich on the bottom end. The more you turn the air
screws in, the richer the bottom end gets and becomes less responsive. However, you are correct in
that this will help bring the idle down. According to SLP instructions, if you're down to 1/2 turn on the air screw and the idle is still too high, then you will have to increase pilot size, but they say this is rarely the case. They also say that to decrease idle, adjust the throttle cable and slide synchronization down to 1800 RPM. I tried this too and it didn't work. I'm stumped!!!

TRY TWEEKING THE CHOKE WHILE YOUR THROTTLING UP. IF YOUR LEAN THIS WILL INPROVE THE THROTTLE RESPONCE. IF YOUR RICH IT WILL MAKE IT WORSE. THEN YOU CAN CHANGE THE AIR SCREW ADJUSTMENT OR PIOLET AS NECESSARY.
