Question about Yamaha Motorcycles

Hi, Anonymous start with 1 1/2 turns out then you will need a vacuum board or 4 vacuum gauges to sync all four.
For this scenario, you will need your service/owners manual if you can't find the first and best tool you ever bought for your Yamaha, despair not, for a mere $10 you can download another one.

SOURCE: idle speed problems
You have to sync thecarbs and also you will have to reset the air-fuel mixture screws.
One of the carburators should be factory adjusted, I dont wn a kawasaki but I own a YAMAHA SECA XJ750R and thro it I am sharing my experince.
Once you have located the factory preadjusted carburator you can thn set the others to its specs. I use the feeler gauge to do for my bikes carburators and it works fine.
With regards to the mixture screw..... get the all in tightened but slowly aas to not damage the pin end of it!.
Start the bike and get it to normal running temp and thn set the screws 2 and half turns out...you may need to set your idling speed before you begin this setting of the mixture screws, you prolly will hveto go higher on revs or vicecersa ....onc eyou are at the mixture screws and adjusting them , you will surely note the differenc ein sound of he bike an its idling ..
Hope this will help.

sounds like the main jets are partly pluged, you must remve all brass jets and seats including needle jet and its slide soak in carb cleaner and blow out with compressed air only.. hold up to bright light to verify if all are clean. jim

You can fail emissions on a bike in arizona ? Wow i thought california was bad....anyhoo let's get to your concerns....All those srews should be very close to the same setting....rule of thumb is start at 1and1/2 turns out on each screw, almost any gasoline engine will run at these setting then you can fine tune from there.....no wonder you had bad idling problems...Good luck to you friend....Tim
