Hello,
After six months of sleep my SR has starting to roar again on this morning ...
... but... something doesn't seem OK.
Here's the problem: although the engine is hot, is runs only with choke middle opened. If I release the choke, it slows down and then stops.
I've tried to check with Colortune, here's what it says:
- choke on, flame is orange-ish (obviously, rich mixture);
- choke off, flame is blue-ish. It should indicate right mixture, but as I wrote before the engine slows down and after a little it stops. It keeps on running only if I twist the grip a little bit but, doing that, the engine backfires.
(Engine is as factory fitted, standard air filter and muffler.)
Could it be something connect to lean carburation? I remember that something like this happened also during last times I started the bike, but in a very minor way.
Can anybody help me?
Greetings!
