#104730 eps_racer (User) Fresh Boarder Posts: 6 I know, another jetting question, but I need help 3 Months, 3 Weeks ago   Hi guys, I just hit 1050 miles on my 2007 RS 1700. I just installed a set of V&H long shots, and an open K&N filter. Took the bike on the hwy and couldnt accelerate past 40mph. I know I need more fuel, so I bought a Speedstar jet kit and followed the tech instructions on this site, but some things arent adding up. My main jet is a 182.5, but the jet kit only goes to 175. Also after reading other tech articles, I am also going to radius the manifold, install a larger seat valve, block off the AIS. What main jet, needle clip, and pilot jet do I need? any help will be greatly appreciated..I dont want to mess this up and I know you guys are great Thanks   Logged     The administrator has disabled public write access. #104733 Musky (Moderator) Doc took Grams beer Moderator Posts: 13084 Re:I know, another jetting question, but I need help 3 Months, 3 Weeks ago   Port the manifold and get the float level right before you do the jetting. Not sure what jets come with the speedstar kit. If it has a 167.5 and a 170 those are the 2 you will most likely need. I would start with the 167.5 main, Clip in the 5th groove from the blunt end of the needle, PMS at 2 1/2 to 3 turns out. Leave the stock pilot in there. Do the WOT. If the main checks out move the clip to the 4th groove from the blunt end and tweak the needle and PMS from there.   Logged       The administrator has disabled public write access. #104746 eps_racer (User) Fresh Boarder Posts: 6 Re:I know, another jetting question, but I need help 3 Months, 3 Weeks ago   so a smaller jet size? I thought I would have been too lean already. I guess the theory is the needle is actually coming out of the jet farther so the size can be reduced...is this correct??? The jet numbers are getting too small for me to read, even with a magnifying glass..ha ha...but i will go with the 170 and 5th groove. thanks   Logged     The administrator has disabled public write access. #104760 DocShadow (Admin) Hmmmm .... send beer Admin Posts: 10750 Re:I know, another jetting question, but I need he 3 Months, 3 Weeks ago   The needle is thinner than OEM so you need to go down on the main as you're richer with the aftermarket needle.

I was running the 167.5, 35 pilot... but after wot I am running 165 mik. 35 pilot, needle 4th from blunt, pms 3 turns. Its never ran any sweeter! Sounds just like Curts, can pull tree stumps, and gets an average of 47.2 mpg.   Logged     2004 Midnite Silverado   The administrator has disabled public write access. #105169 eps_racer (User) Fresh Boarder Posts: 6 Re:I know, another jetting question, but I need help 3 Months, 3 Weeks ago   Hi guys, well took your advice and dove in. My wife thought I was crazy when she came out to the shop and saw my new bike 1/2 apart. Just want to say everything went real smooth thanks to all the tech articles and your advice. I really felt like I had everyone there helping me out. Took the bike out WOT test and all...and it runs excellent.   Logged     The administrator has disabled public write access.
