At one point during my ride today, she was backfiring terribly on deceleration...I pulled the clutch in and she stalled.
Started right back up again without any issues, but seem to run a bit "notchy" for the rest of the ride.
When I got home, I tweaked the idle mixture a bit leaner but that doesn't seem to have made a difference.
For the record, I just de-winterized...fresh (no ethanol) fuel...1 oz of Seafoam into tank...new oil and filter...new iridium plugs...air-filter is cleaned and re-oiled...nothing out of the ordinary.
Backfiring on decel could be too lean.
Guys here will up a pilot to help, but pop has never worried me on decel if the bike runs good.
Maybe you're mixture was just on the lean side before and there is just a bit more oil in the air filter now than before, after the clean and change you did.
You could run the bike to temp and check the mixture properly from both directions.
Maybe you need to go just a touch richer.
I'm lucky enough to live a short ride from Auscanvet.
I'd fiddled with carbs on other bikes before, but will always try and learn more from those that know more, and have more experience with the bike.
He took the time to run through the whole set up for me,
Showing a few things to make it easier along the way and explaining things as he went along while working on it.
Even if it's something i've done before, i always check as there's always a smarter bloke than me here, that knows a better way to do it.
Hopefully one of em will be along shortly for other thoughts than mine.
