At 6000rpm the needles come right out and the bike is on pure main jets. These are intentionally too big to cut down noise...correct jetting produces a snarl so the over-rich engine note is somewhat muffled. This muffled high revs note stays under the noise regs and allows the mid-range exhaust note to be more robust. You need to adjust your pilot screws out ...there's notes on this in the files section. That stops the popping. The pinging is probably mechanical...many have commented but in an air-cooled engine where you sit on top of the heads, pinking is actually MUCH louder and nothing like the distant tinkling one hears in a car. A bike has a distinct and loud CRACK when it detonates. Jon

a.k.a. idle mixture adjusting screws. Not the idle speed knob.

You start to see the proper website, but immediatrely a popup starts, consumes your entire screen, and stays there as far as I can tell. I didn't hang around, don't want to give it time to install stuff on my computer.

Subject: [W650riders] Time for tune-up *** The pinkering I don't think is anything as most of the Ws seem to have that..but the exhaust popping is symptomatic of your carbs needing properly jetted as they are not jetted so well from the factory. Have your factory airbox removed thats located behind the side panels that the carbs breath into and put them on some K&N single filters for each of your carbs and have the carbs rejetted to suit the new air setup and you will have a roaring machine without any popping. Music Matty ' Pop quiz ('cause I don't know the answer): Engine pinging on acceleration or uphill, and exhaust popping (like a baby backfire) on downshift are symptoms of what, specifically? Mixture? Carb asynch? Something else? / Rob |

开云体育Congratulations, Dick - Victoria Police here has a
couple of ST1300s, I inspected one - lovely bike, and they like 'em.?
Haven't heard about the weave here, but they don't have a freeway on the Island
and they don't wear?a topbox either.? I presume you won't regularly
travel at 125-145 mph, but maybe I'm wrong?..?? How many bikes will
that leave in the stable??
?
