Idling

[Downgrade]

After riding for awhile, my bike idles really high it seems when Im at a light/stop sign when Im holding in the clutch, but is fine once I start moving. Im not sure what causes that, Ive tried to adjust engine idle, so its not so loud, but seems like it has a hard time idling when I first start the bike.

Also, the bike backfires when I turn it off after I ride it for 10+ minutes at 55-60mph, but only sometimes. Any ideas?

First........... Yes, it will have a hard time idling when you first start the bike. You need to use the choke, & reduce it, bit by bit, until the engine gets warmer. That's what happens with air cooled engines.

second ......... the engine idle should only be set when it's HOT, & the choke's OFF. Suzuki recommend 1200 - 1400 RPM, so use this as your starting point to get it set to what you're happy with.

Yea, I guess my main problem is the choke cable doesnt work, Ive tried using wd40 to loosen the control, Ive taken it off the carb, I guess I just need a new cable, hopefully

I only adjust mine when the motor is warm. I have mine set a little higher so when the engine is cooler or first started, I can still let it sort of idle by itself without stalling. I have noticed when you set the idle to idle good at warm engine temp, it does not idle good at cooler engine temp. Hope thsi helps. GZBrian.

How many miles since the last valve adjustment?
