SHEEBANSAVAGE Posted March 2, 2005 Report Share Posted March 2, 2005 Hey guys, I have a 03 shee with FMF fatty's+ power core 2 silencers, boyesene power reeds and a uni air filter...Since this winter I cut off the end of my airbox lid for more air flow... I live a sea level and here is the issue I am having.... Before the airbox lid mod=stock pilots, 270 mains and needle in third position and airscrew I believe it is 1 and a half turns???...It ran awesome... After airbox lid mod= stock pilots, 280 mains and needle in 5th position, and airscrew 1 and a half turns and plugs are coming out grey... I figure it would run ok in the summer when temps get hotter but I need a fix for now.... Where is my next jetting option...Bigger/smaller mains, bigger/ smaller pilots , what position needle and what adjustment on the air screw Let me know what u think Quote Link to comment Share on other sites More sharing options...
FIRST BANSHEE Posted March 2, 2005 Report Share Posted March 2, 2005 grey plugs are not good, 280 mains sound to small for winter. I would try 300 and see how they work. Quote Link to comment Share on other sites More sharing options...

Probably you may nee to go back to the 4rth or 3rd clip position in the needle if you put 300 mains. Quote Link to comment Share on other sites More sharing options...
SHEEBANSAVAGE Posted March 3, 2005 Author Report Share Posted March 3, 2005 Cool, thx for the replys...Today I bought and installed 300's and moved my needle back to 3rd position. Tomorrow I will run it and see what happens... I will post back then.. Quote Link to comment Share on other sites More sharing options...
SICK BOY Posted March 3, 2005 Report Share Posted March 3, 2005 Let us know how it runs,I would have went to 320's and left the needle at the 3rd clip. Quote Link to comment Share on other sites More sharing options...
SHEEBANSAVAGE Posted March 5, 2005 Author Report Share Posted March 5, 2005 (edited) I ran the 300's and ended up moving the clip to the 5th position and I was just starting to see light brown color. So I went and bought 320's and 340's and will maybe try again tomorrow. Another question...Before I changed the clip position (3rd with 300's installed) my bottom end was good and would climb the hills easily in 2nd gear. After I moved the clip to the 5th position, I totally lost by bottom end until the power band kicked in and I couldn't climb the hills at all. I had to run into the hill in 1st instead of 2nd. I needed less speed due the start of the hill but I needed to be in second gear to climb the hill but I could only get into first because it would bog out in second as soon as I hit the hill... Is that part of the power range dependant on the needle position or what? I need to have that low end grunt as well, so will the correct main jet and needle in 3rd position fix that??

SHEEBANSAVAGE Posted March 7, 2005 Author Report Share Posted March 7, 2005 Anyone with any answers or what??? Quote Link to comment Share on other sites More sharing options...
rocketboy Posted March 7, 2005 Report Share Posted March 7, 2005 your bogging range would be a combination of a pilot and needle clip postition ,they overlap ,youll need to dial it in on both circuits .i know if im off on a jet circuit with my carbs by a good margin itll effect the othes even if there set correctly . alot of pepole opt to jet for summer with no lid/or a cut modified lid and in winter just throw a original stock lid back on to richen her out a couple main sizes.good luck Quote Link to comment Share on other sites More sharing options...
SHEEBANSAVAGE Posted March 7, 2005 Author Report Share Posted March 7, 2005 Ok that makes sense...I want to get the clip in the 3rd position and the proper main, so this should fix my bogging... I will try and do a run after work this evening and I will let you know how it goes. I installed 320's and the needle is back to 3rd position so we will see what happens. Thanks again Quote Link to comment Share on other sites More sharing options...
SHEEBANSAVAGE Posted March 8, 2005 Author Report Share Posted March 8, 2005 So I tried again this evening and the 320's didn't solve it neither did the 340's.... Am I going to have to higher again?..I think I am going to have to,,,My next step is 380's and 400's..... This is not a hard process and it seems like posts I made earlier people have done this mod before...Can I get an opinion on this from anyone that have done this mod before or anyone that has a good grip on jetting... Everytime I try a new jet and it doesn't work, I have to go and buy 2 more for the next step up...Can someone give me an idea on the next size because soon I am going to have a whole jet collection.

NEVER SATISFIED Posted March 8, 2005 Report Share Posted March 8, 2005 if your at sea level try this setup and adjust the pilot as needed... 340 mains... 30 or a 27.5 pilot and needle in the 2nd clip ( reason being is that puttin on new reed cages cause your bike to run rich) and if your using race gas that also makes it run more rich... try that Quote Link to comment Share on other sites More sharing options...
SHEEBANSAVAGE Posted March 8, 2005 Author Report Share Posted March 8, 2005 So you figure I should try this even though I still have my stock reed cages? I just changed my reeds...But anyway thats another option..I'll try that. Thanks Quote Link to comment Share on other sites More sharing options...

IF YOU GET A RAD VALVE AND POD FILTERS JUMP TO 340 AND A 30 PILOT AND PUT THE NEEDLE IN 2ND CLIP.. AIR SCREW 1.5.. FURTHER IN YOU GO THE RICHER IT GETS ON THE AIRSCREW.

What about 340's and 30 pilot and 1 and a half on the airscrew... If its too rich, I could go to 320 mains with a 30 pilot and adjust the needle as required. What do u think about that or should I order the 27.5 pilots? Edited March 8, 2005 by SHEEBANSAVAGE Quote Link to comment Share on other sites More sharing options...
