That makes sense since the mileage went down over time. Sounds like gradual decay to me. To answer Shores question they only had BAC's when I bought this 2001 new. $150 for the BAC plus costs for a re-jet kit. I think the K&N I bought was $25. Plus the 3m goop I think $3.50 way cheaper and I am still using it till this day. Seemed like a good idea at the time. He isn't talking about a BAK. He is talking about a K/N replacement filter that replaces and installs in the stock air box.   Logged     dave   The administrator has disabled public write access. #1023089 Shores (User) Go getchur scooter!

Goes inside the stock box and doesn't require re-jetting. http://www.ebay.com/itm/Yamaha-K-N-Air-Filter-DBY-ACC56-12-85-XV17-Roadstar-Silverado-YA-1704-/331963082019?hash=item4d4a8aa523:g:FI8AAOSw~gRVnUy2&vxp=mtr   Logged     Last Edit: 2017/09/29 15:10 By Shores.   The west is the best - Jim Morrison Photo by GreenMachine   The administrator has disabled public write access. #1023236 bdenzler (User) Fresh Boarder Posts: 21 Re:gas mileage getting worse 4 Months, 3 Weeks ago   So I am guessing I need a needle set and a main nozzle?   Logged     The administrator has disabled public write access. #1023238 SKWEARpeg (User) Platinum Boarder Posts: 12885 Re:gas mileage getting worse 4 Months, 3 Weeks ago   bdenzler wrote: So I am guessing I need a needle set and a main nozzle? Start with what you need. Do the needle and seat(float valve), and while your in there, check the jetting to make sure its stock. Write down everything that's stamped on the jets, not just the size. A magnifying glass helps a lot.   Logged       The administrator has disabled public write access. #1023240 bdenzler (User) Fresh Boarder Posts: 21 Re:gas mileage getting worse 4 Months, 3 Weeks ago   so that would be a needle set and the main nozzle?   Logged     The administrator has disabled public write access. #1023242 SKWEARpeg (User) Platinum Boarder Posts: 12885 Re:gas mileage getting worse 4 Months, 3 Weeks ago   bdenzler wrote: so that would be a needle set and the main nozzle? No, that would be the needle and seat. It comes as a set, with a new oring on the seat half of the float valve. I'm not really sure what your talking about, when you say main nozzle.   Logged       The administrator has disabled public write access. #1023243 bdenzler (User) Fresh Boarder Posts: 21 Re:gas mileage getting worse 4 Months, 3 Weeks ago   please excuse the second post of the same. I see in the IPB that it is the .Needle Valve Set 4SV-14107-20-00 5UH-14107-20-00. I now see the o ring you are speaking of. Thanks again.   Logged     The administrator has disabled public write access. #1023387 bdenzler (User) Fresh Boarder Posts: 21 Re:gas mileage getting worse 4 Months, 3 Weeks ago   Yea I got that but these were not available at the time I made the filter for my scoot. When I if ever need to replace my "home made" filter I will surely invest in one of those. BTW just picked up my needle set today and hopefully replace it Sunday after I finish cleaning up after Irma destroyed a bunch of crap at my place. We got hit pretty hard here in Brevard County. Just wanted to have no misunderstandings.   Logged     The administrator has disabled public write access. #1024836 bdenzler (User) Fresh Boarder Posts: 21 Re:gas mileage getting worse 3 Months, 3 Weeks ago   Well mileage is now back to normal. 43 when running slow and 39 when i get down the road. Thanks for the advise on the fix. Only took me three try's until I got iy not to leak. Float bowl gasket issues which I resolved. Thanks again SKWEARpeg....   Logged     The administrator has disabled public write access. #1024841 SKWEARpeg (User) Platinum Boarder Posts: 12885 Re:gas mileage getting worse 3 Months, 3 Weeks ago   I’m glad that fixed it. It’s usually the oring on the seat, that starts letting fuel past. Once it starts leaking, it can get bad to the point of the bike not even running in pretty short order. Was it the little bitty oring on the flange, the one that seals the accel pump, that mysteriously disappeared? They have a habit of doing that.   Logged       The administrator has disabled public write access.
