Hello,
I'd like to use your wisedom and experience to get ahead of my problems. Or maybe issues. I'm lacking both knowledge and money, so I have to precisly plan everything to buy, and can't risk any misteakes. My current setup is :
SP 50, 2008r.
Streetrace 70cc
LeoVince RR
Malossi Multivar (old, 16x13), 3x4g+3x7g
Polini Air Box
21mm PHBG, main jet 80.
Vmax aprox 95km/h.
While I was on 17.5mm, stock airbox and 6x7g rolls I could go even 115km/h
But I was affraid of the engine being too hot, so I bought 21mm.
I started with 92 main jet, but it was hell. Had to drop to 72 jet to get it going.
Now I bought S6 Pro Replica, as Yasuni R and S6Pro are to expensive here.
For now my issue is : Runner starts at 6.5k, accels nicely, than on "cold" start (when I just started it after night)
it gets strange rpms lost at about 7k till 9k, it seems like it has too much fuel, it makes strange sound from the exhaust, and I feel on the handles that it can't rev up. If engine is hot - this issue does not happen.
My brother says that this is 2 stroke engine, and that's just it's way of working while it's cold.
Second thing is that I know I should start it with choke on (I have manual now) but although it ONLY starts
with choke ON, I have to always turn it OFF 5-10s after start, if I won't do it, it will fall off, and die on me. Usually I try to sit on the bike after it has 4 stripes of temp on the screen. I know that switching from stock airbox onto polini air box, I had to upjet. BUT what I don't know is about how much? When I bought Gilera, it had 70 jet on it. And it was 50cc, all stock. Then I went from 70cc streetrace, and with stock airbox I was getting best results with 72 jet. More was giving me stuttering effects on 8k rpms when I would violently pull to full throtle. Now I changed to 80 jet. Should I go higher, or can I try lower?
Does little gold screw I belive it's called pilot - affect only idle engine speed, or also whole throttle operation?
I know these are quite specific questions, but these are only those I can't bare to find any answers for.
Thanks in advance,
Bart
