Popping before and after cleaning. TOO RICH?

[muaymendez1]

Hey guys. jose here with my 96 rstd. I just purchased this bike 3 weeks ago.

The bike had a hard time rolling when cold and also popping at idle and decel. I decided to adjust the valves and clean the carb.

All intakes were tight at 27,600k miles exhaust were fine. Plugs looked good and I changed them anyway. The carbs had some gunk build up.

Everything back together and the bike pulls like a monster but i get popping through the pipes at Idle. Accel and lots of popping on decel.

My lil bit of experience tells me this is a rich condition allowing raw fuel in the pipes which get ignited by the heat and there fore make a popping sound in the pipes.

Question if i am correct is.How do I lean this out a bit to get her running better.

the bke was bought with aftermarket louder pipes. not sure the make of pipes. the baffle are still in and yet it sounds pretty loud.

I have yet to spray carb cleaner by the intakes to see if any change in RPm which is what i read to do to locate and intake leak.

does anyone have a pic of the pilot screws. I looked for the caps and think i found the holes to be drilled out but I am not sure

Hey Jose,

That's a really nice bike you have there! After all of the great tune up work you have done there, the next thing I would do is to Sync, the Carbs. with a Manometer. The Idle Mixture Screws are set with an Exhaust Gas Analyzer at the factory. If you do not have a Manometer, I live in South Central Pa. and you are more than welcome to come by and I will Sync. your Carbs. for you. I can even offer overnight lodging. It is always a pleasure to meet a new VR.ORG member. If you come on a weekend, we can even get some riding in.

Well . went for my first rider after valves adjusted. 125 miles and only 2.96 gals of gas. Speed was around 45-70. Back roads, hwy, stop and go. Not easy on the throttle.

I am really surprised to get 41 mpg, i was a lil nervouse that I would need fuel at teh wrong time so i pulled over at the first gas station over 120.

So i guess im not running rich and If I am.Ehhh who cares .Queeny is riding wonderfully, and pappa is happy.

Now on to discover the darkside

or not!

Popping sounds through the exhaust indicates a lean mixture. It looks like your bike has aftermarket mufflers, they probably flow better than the stockers. Bikes are tuned from the factory with the stock exhaust and run a little lean anyway. Better flowing exhaust means more air in the air/fuel mixture, a lean condition. Did you note the color of the plugs after they were removed, white is lean, tan is good, black is rich. I would look at the plugs closley after a few miles and go fom there, I really think you will need to go up in the main jet a size or two.

My plugs were fine when I pulled them a week ago and the outside dirt and agin shows that they are not new but my buddy thought they looked good as well. No white or black just tan. I had new plugs ready to go in anyway so I swapped them and he took my old plugs for his goldwing.
