Ec 300 2008

[5valve]

Got this used bike, not in perfect shape, but starts first kick hot or cold.
When I roll it on straights, no problems, valve opens, power acceptable (huge)
Low and mid speed grunt is acceptable. I'm just used to 4 strokes, so now I occasionally dig in.
MJ:168
PJ: 40 (replaced 42)
stock needle N1EF #3
Air: 1.5 - 2.5 (2.5 kicks in power quite sooner)
Series 1 carb
No mods (maybe sth wil surface, when I start digging into engine, which i love doing)
13:52 gears, will go to 51.
1:50 sint offroad premix
95 fuel, fresh mix every ride
Power valve inspected, cleaned to the bone.
Issues are:
Idling is sometimes high, sometimes just about to sign off, but it doesn't. I think it is minor bike lean angle sensitive.
Steep slippery full throtthle uphills, tested 2nd, 3rd gear, sun, rain mode, bike cant rev out. It is close, but seems like hitting rpm limiter. Its just that small amount of less wheel spin, so you cant reach the top. 3 rd gear got me higher, due to more speed, but feeling of not enough speen was again there.

When surface is flat, bike revs and overrevs normally and hugely.

Is it all about the float level being too high? (for starters?)
