Jetting help

[Monsterenergybanshee2014]

Hey Guys I was wondering if I could get a little input about the jetting I am running on my banshee. I have the following done to her:

 

 

Stock mikuni carbs with

Stock Bore Stroke on engine

compression is 120 per cyl

280 main jets

25 pilots

I am 882ft above sea level

I also have timing plate mode +4

and FMF fatty and powercore pipes

and K&N uni pods and outerwear covers

 

 

My question is do you think I should bump up my pilot jet to a 27.5 and or 30 pilot jet she runs pretty nice fires first kick but I have 8 months into rebuilding an old 91 J arm frame and I really want to be sure I don't lean her out too much a blow my motor. Any thoughts?

Well changing you pilot is not going to affect anything other than the bottom end. If it runs good and has for this long I would say you are pretty damn safe. If you were going to blow it up would have already happened

I have the same setup but mine liked 27.5 pilots and 300 mains. What are you plugs telling you?

I have only rode this twice since it got rebuilt and plugs looked a little on the lean side when I did a plug chop. That's why I thought I should ask she runs idles strong has no break up in power but I just thought she might be just a little too lean . I tried running a 300 main jet and she didn't like that so I thought maybe bumping up my pilot jet would help me so i guess what the hell i have had this machine apart a million times im gonna buy some 27.5 pilot and just see how it turns out.

 

 

 

 

Thanks

If your plug looks lean in a wot throttle fifth gear plug chop then changing your pilot isn't going to help
