Thank you for all of the information. I think I'm going to order a set of colortune plugs to help with the air/fuel mixture. I believe the plugs are 12mm on the RSV correct? Anybody use these? What are you thoughts on them?

So I'm gong to add a little more here. I changed the plugs yesterday. They were all very dark on the end. They are supposed to be somewhat tan aren't they? If that is the case, does that mean I am running to rich? Oh, And I put the stock butchered exhaust back on for now. Now, syncing the carbs just makes sure they are doing the same thing right? It does not do anything for lean or richness. I'm sure there is a procedure for that. Thank you VentureVet for the info. I think that is what you were giving me but I just am not sure how to go about doing what you said. It's always a good feeling when people are willing to help. I know I'll get this bike into shape and running great again. I guess it just takes time and some hints.

EUSA1 tells me you are a Pro. How's this idea? I'll come up there to you and you can show me how to do this. I'll buy you a beer.

I came from several Victories. Both Visions. Lost my last one to a divorce. Man, I loved that bike. They can get warm. I just recently purchased a 99 RSV. working through some issues since it sat for 3 years in a garage and never touched. The price was right and gets me back riding. I do like the RSV. A nice comfortable ride. I haven't taken any long trips on it yet though. I did a lot on my Visions. Those engines are so rock solid and power through the entire band in every gear. I'm a road captain for our local dealership. Ride them all a lot (Both Victory and Indians). I like the Tour Master also. Love the looks. But I love the way I can stretch out on a Vision. I guess there are pro's and con's to EVERY bike. You like the Vtwin sound, you like the 4 or 6 cylinder smoothness. It's all preference. I think my problem is that I like them all (except I'm not a HD type of guy). I'm not against the bikes (I like the look and ride), it's the attitude that drives me away. I have to comment on the dealership issue that someone brought up. The Indians and Victories, like I said, are rock solid. They just work. And there is a large network of people to help also. Whichever way you go, you will love it. I'm sure of that. Good luck hunting and ride safe. OH, I want to mention one more thing. It is odd for me coming from the Victories regarding the heat. It is warm on a hot day, but on a cool day, it sure is nice to put a hand down next to the engine and get some warmth. I miss that on the RSV. They run so cool compared to what I'm used to. On these cooler days and I'm out riding. I don't have my built in motor hand warmers!!!!!!!!!

I had my carbs synched by the local garage but I'm not sure they did it correct. I want to verify it but don't want to pay them again. I need to know how to do this anyway.

Anybody out there have a Morgan Carbtune for loan or sale?

I get that. I have been told that the AIS circuit is there to burn extra fuel in the exhaust. Someday I will have to have them looked at again. I've put a bit of money into this bike to get it running and I just can't stand the thought of paying the local dealer another $350 bucks to do it again. Although I think he should do it again for free since it wasn't right the first time. At least I can ride it. It runs good and sounds good. But I do agree with you. Just happy to be able to ride again.

So simple. But it took someone with know how to tell me how to fix it. So the backfiring and popping was coming from the AIS circuit. From what I have learned and been told is that puts more air into the exhaust to help burn anything fuel that is left over after combustion. So, we disconnected the front and rear AIS connection and put a cork in each of them and put the tubing back in place. I didn't have any corks so I went across the street to a local Italian Restaurant figuring they would HAVE to have corks. They did and gave me a few. One cord is awfully long so I cut one in half. Put one half in the front circuit and other half in the rear circuit. put the tubes back on and started it up. I just couldn't believe my ears. No popping or backfiring. So I took it for a test ride. Perfect. Just incredible.

You are the man. Not a single pop or backfire now and all fixed through text messaging. Incredible.

Ok. I bought a 1999 Venture a few weeks ago. I know the last guy that had it let it sit for about 3 years. He also apparently tried to do some exhaust mods to the stock exhaust and totally butchered it. The bike runs pretty good so I thought I would take it into the local shop and have the carbs cleaned and synced. They did but it still backfired a lot. They said it was the bastardized exhaust causing the issue. So I bought some LA Custom slip-ons. I just put them on and it did not fix anything. Sounds louder and good but still backfiring. This all happens with little to no load on the engine. I also note that if I am in 3rd or 4th gear and cruising along and decide to speed up a little, it tends to bog. I told the local shop this and they said I need to rejet. I'm very new to Yamaha and know very little about their engine setup. It is just plain embarrassing to ride like this. I've hear different things about some circuit that is supposed to open something up during decel, low load, etc. to let more air in or something. What do you guys think? I know somebody has the answer and I'm not quite sure that the garage has the answer. I already spent money on a new exhaust that they said would fix it. I'm running out of money. Any help would be greatly appreciated. I have not replaced the plugs yet. Thank you.

I just picked up a 99 RSV. I'm liking it so far. But that space under the gas tank between the cylinders is really ugly. I see you have that coverd. What is the cover just under the gas tank and between the cyclinders? covers up all the ugly stuff. Where did you get them? Thank you.
