Jetting Problems with DRD

[blackYFZ450]

Just got DRD slip on and jet kit with K&N Fitler and Pro Design intake. Pipe recommends a 172 main but the kit doesnt go any higher than a 165?? do different brand jets have different size holes????? any suggestions would be greatly appreciated

I had the same problem I had to drive 60 miles to a Yamaha shop in Zepyherhills Florida and they had 2 there so I bought 1 and installed it which is not easy either make sure you have a jet wrench because the stock jet is probably torqued down pretty good and do not touch the floats, if you have a problem in either finding one or need some installation help via email ,feel free to ask Email address is sbarrucci@aol.com any way the Dubach pipe rocks and you`ll be glad when you sort the temporary problems out.
