The Jetting looks good. Id go with JD's advice about the SVS.
You can't fog the carb, and hope to get on top of the SVS. When it gets bad, you have to remove the exhaust, saturate the inside of the exhaust chamber(s) with Seafoam for a deep clean, add a can fo Seafoam to a new tank of gas after cleaning the exhaust chambers, and ride it like you stole it. If you can find one of Curts post and click on the link by his sig pic, it'll take you to his website. You can track down his deep clean for SVS method there.

Ok, so I just ran into the previous owner of the bike and had quite a lengthy conversation about what issues he may have had w/ it. I found out , much to my disappointment,that he had been chasing the same running issue for quite a long time and paid the local Yamaha dealer what he describes as " large sum of money " trying to solve the same problem. He said that they had also rejetted the carb in an attempt to stop the rear cylinder fouling. I am going to look up the SVS cure in the forum and try that. I also want to dump the factory carb. Maybe it has some type of internal issue that everyone, myself included, has been unable to correct. What is the HSR reccomendation and a part number that I may be able to locate it from ? 42 or 45 ? |

Per your handling issue, in case you were not aware, DO NOT trust the alignment marks on the swing arm for the rear wheel alignment. These are notoriously wrong. If you aligned the rear wheel by those marks, that could very well be part / all of your handling issues.

SVS has absolutely nothing to do with the type of carburetor, and everything to do with slightly narrow valve guides and riding like a grandpa. The permanent fix is to have a valve job done and ream the valve guides plus slightly heavier valve springs
SVS was only a problem on the 04-05 roadies due to he head design which Yamaha fixed in 06

Well, I cannot speak for how the previous owner rode it but "grandpa" would seldom be used for the way that "I" ride it. When it is running properly. Also , I guess that I am a bit confused because literally , from my first post on this forum, EVERYONE on this site has said that proper carb adjustment has EVERYTHING to do w/ SVS issues. |

A rich runner will foul it up. Running too much oil will foul it up, and being an 04-05, its predisposed to SVS. I've seen SVS in 1600s from ridiculously jacked up jetting, yes, but on an 04-05, a few folks have had to go to the valve guide reaming to get it to stop. Yours is just the bad luck of a poorly informed shop getting the work and not fixing it right, as there WERE technical service bulletins issued on 04 and 05 models for this issue. If you take some time and fix it right, you'll have a kick ass bike. If you sell it because you don't want to fix it and just try to change up plugs and get it running good enough to sell without telling the next guy what is up, you might get a decent dollar out of it, and be a dick. If you sell it and tell the next guy what is up, he's gonna want some consideration for what needs to be done to make it solid, and if he's not a Road Star guy, he'll think you are up to something. Either way, your best bet is to get your SVS fixed, because it hasn't been fixed right yet. |

Being a dick is really not my style , unless it is warranted. I kinda feel like I am on the receiving end of that type of situation right now. I am just tired of throwing money at this thing and not fixing it. If there is a fix , I am all in. Pissing money away , I am not. That being said, do both heads have to be repaired or just the rear one ? What ACTUALLY needs to be done ? Does it require motor removal or can the repair be performed in the frame ?

I don't think any of us are trying to be dicks. Well most of us anyway  We just really want to know that your bike is running properly and that you are happy with it.
Like I said before the permanent fix is to ream the valve guides but only a couple of people have had to resort to this.
Also, no you don't have to remove the engine for any of these fixes. You just need to remove the exhaust for Curt's SVS fix. And to do the valve job the heads will come off without pulling the engine and you should do both heads so they both flow the same
Here is some good info and Curt's SVS fix http://www.cherswitz.net/Projects.html

Hey guys, is 185 main jet stock? Why would it have a barons adjustable needle with the stock jet. I would think 170 or 175 would be better. |

182.5 is stock on a 1700, and I wasn't saying anyone was being a dick, but I certainly understand your frustration. If you have not tried Curts SVS cure, I certainly would if I were you. As Tug said, only a few have had to do the ream repair. If Curts cure gets you running right, getting the jetting right and keeping 4 quarts only of oil in it should get you fixed up. I know at least 2 people jetted right with 04s that never have had SVS issues. Patience is at a premium, I understand, but as it says at the top of the page, YOU CAN DO IT! |
