Newbie...just bought 2014 300R, need advice

[95jersey]

Test ride of my new 14 300. This is before the re-jet. Just putting around trying to get use to the bike on some single track and small hills. The video never does the whoops justice, but you can hear the bike motoring through them.

I'd suggest either NEDW/NEDJ as a starting point. NECW and NECJ are your half clip leaner alternatives if you wish to fine tune. Not sure about the bikes in the states, but here in Australia we get assorted pilots and mains with the bike. Should be working around the 40/42 and 172-178 range.

are these needles in order of lean to rich? What would be a clip leaner than nedj? I know necj is a half clip

Nothing that I know of Matt. As you've stated, the NECx is half a clip position different. The diameters are richest to leanest: F, G, H, W, J, K, L.

FOUND THIS ON ANOTHER SITE (BUT THINK THEY MAY HAVE GOT NECJ AND NEDJ THE WRONG WAY ROUND SO USE DISCRETION):

The specific needles being tried are from a 2008 Suzuki RM250. Again for ease of reference and understanding of which needle is rich or lean they are listed below from rich to lean in 1/2 clip increments:

NECF
NEDF
NECG
NEDG
NECH
NEDH
NECW ('W' is substituted for 'I')
NEDW ('W' is substituted for 'I')
NECJ Part Number 13383-37FE0
NEDJ
NECK
NEDK
NECL
NEDL

Needle Diameters, again, rich to lean.

NECF/NEDF 2.705
NECG/NEDG 2.715
NECH/NEDH 2.725
NECW/NEDW 2.735
NEDJ 2.745
NECJ 2.745
NECK/NEDK 2.755
NECL/NEDL 2.765
