New to gas gas. Ec300 doesn?t scream

[Lozarus]

Hiya new to gas gas. Only had 250f?s in the past and 125
2 strokes..
Got a 2010 Ec300. Just had a new top end. Load of compression and runs well.
Has loads of bottom end but just seems to lack top end like it doesn?t scream. Is this just a characteristic of this engine? I think it?s running pretty rich so am gonna do the jetting. Any particulatar brand to go for or are jets jets?I?ve checked the power valve all ok. Repacked exhaust etc
It feels like apart from the bottom end kick in the first few gears that it runs out of puff feels like a cr125 top end. Any pointers would be appreciated.
My understanding is That I can lift adjust the height of the main jet to lean it out some? At the moment if i lean the bike Right over fuel doesn?t come out of the overflow
Thanks for your help

RM250 needle NEDJ

St N1FE is best cut in two so you aren't tempted to keep it.
.

Then find the right main circa 175

My mate has a 10. We put that needle in. He scoffed as they look the same. Now he won't shut up about it. Try clip 2 from top but don't be afraid to experiment. Our gas / altitude will likely be slightly different.

If you really want a screamer throw a N3CJ in there, has a more angry transition than the NEDW. I run the NEDW though as the N3CJ can get tiring.

agree, if you are looking for a more old-school 2t hit, then go for the N3** needle, the NE** will still scream, but it is much smoother getting there
