In fact no other's mods, the goatbelly is there, the reeds too, just the mufflers a little bit more open.
I've noticed that , like today, this morning was 17°c she runs perfectly
, start without choke, but needs choke to keep alive (middle), this afternoon around 29 , awfull, the engine is rough, intake noisy (grrrrrrr) not as round ans smooth it is in "cold" mode.
The iddle is 1k rpm
for the batt, in france I can't find a maint free batt
, so it's a new one but...voltage is ok
I've some hot starting issues also, when I stop to refuel she's accept to run only if I walk with her, pushing the start button and on 1st gear "playing with clutch".
I don't know if all these problems are linked but it seem that when the T° increase the carburation is to lean (backfiring, and getting hot, and not sweet engine)
Does the reeds play also on normal throttle (on ride), or only in throttle off ?
does the air mix screw involve in the not iddle mode ? or only at iddle ?
for me the main pb is not so much backfiring but the difference between 17°c and 29°c, between a pleasant engine, round running
, and a rough engine, hurting
just a remark more,
when I've tried to close the holes he has done, it was better...
