Sooo... new slip-on.. terrible mileage

[dmhx1215]

So I bought a slip-on for my 2006 kat 600 and now my gas mileage has gotten terrible. I'm not quite sure what I'm looking for in the forums to search for answers because I'm not exactly mechanically inclined. At least not with motorcycles. So, would anyone be willing to help me? Also have a hell of an afterfire on decel over. Get about 65 miles out of a tank. The slip-on is a two brothers v.a.l.e m2.

Need to remove carbs, drill out the A/F screw covers and adjust to 2.5 turns out. then re-sync the carbs.

Or you could do yourself a favor and get more horsepower and better running with good gas mileage and get yourself a Factory Pro Stage 1 jet kit. Your choice.

is the slipon the only mod? you didn't add a K&N filter did you? +1 on jet kit.

65 miles on a tank... that extreamly low milage I would think more of a leaking float needle that isnt' even really relevant to the slip on.

I would check for that.

The slip on the the only mod I've done so far. I wanted something loud and abnoxious and that's what I got. What is a jet kit? Is it easy to install? And will it fix my fuel mileage issue? Oh and what are the A/F screws on the carbs? I've got 4 so I'd imagine its the same for each carb. And how do I sync the carbs? Sorry if it seems kind of irritating, me being a newbie asking questions, I really just have no idea and I'm more than willing to learn, just have no idea where to start.

And my mileage was great before the muffler.

Read Carbs 102 and get the service manual.

Download the carbs 101/102 pdf off the wiki and it will cover the af screws. With pics! You will need to remove them to do this, perfect time for that stage 1 there talking about! Also, if your reaaallly not mech inclined, how bout putting the stock cans on? Would at least let you know if it really was just the pipe that made that terrible a diff.... but idk...

He has a 2006. That would be carbs 102. Carbs 101 is for Pre kats, 90-97. Or 89-97? Can't remember exactly.

[arsenic]

90-97 600 and 89-97 750.

Thanks for clearing that up. Sometimes my A.D.D kicks in even in my old age

So I've decided to do a stage 1 jet but thats not until next year as the seasons basically over and i don't have the money right now. I am curious though. Could adjusting the a/f screws make up for most of the issues im having or would i have to just rejet everything? Oh and after the a/f screws are drilled out, do I have to re-sync/re-tune the carbs?

Turn you air fuel mix screws out to 2.5 turns as already suggested. A good sync can never hurt
