So after much contemplating I've decided to rebuild my carburators myself. I really wanted to take the easy route and have it done but my need to know whats going on in there and see for myself what the problem was has outweighed my common sense. I need a couple of things from you guys. First money and then someone to hold my hand lol no seriously, If someone could recommend a rebuild kit for the type of jets I should have for the cobra exhaust I would be eternally grateful. I have been browsing kits and they seem to be for OEM which as far as I know wouldnt work because the jets are different. Also, I'm assuming the rebuild kits dont come with everything like the float needle and such, is there a kit that just has everything that can be replaced? I would like to replace everything new so I dont have to worry about it anymore or at least for a very long time. Also, any pitfalls to look out for would be greatly appreciated. Thank you guys again for you guidance.
anybody know where i can get replacement screws for the carburator covers? Last owner stripped them out apparantly.

You don't need a carb rebuild kit specific to any particular exhaust. Just go with the complete RedEye kit. For the Cobra exhaust, they sell a supplemental "kit" that includes needles, springs, etc. (see below); however, I believe you can stick with the 35/100 factory jetting: https://www.partsgiant.com/p326138-cobra-carburetor-jet-kitYou can also purchase replacement carb cover screws from RedEye (see below): https://redeye.ecrater.com/p/20132630/screw-kit-for-cv-diaphragm-capI've got leftover Cobra needles from when I went back to OEM. If that's all you need for your application, PM me with your mailing address - and they're yours. Hope this helps. Terry |

Good point. I *believe* all of the replacement hardware available from RedEye is JIS. Amazon sells some good JIS screwdriver sets - which are a very useful addition to the toolbox when wrenching on metric bikes. Terry |

If you could, can you take photos of your rebuild adventure. This is something I may like to do myself too. I'm always open to learn new things...  |

not 100% applicable anymore. there is a new std that works and most of the so called special companies that are selling JIS are actually selling the new standard which can be bought anywhere including harbor frieght. Most JIS advertised screwdrivers sold today by companies like Vessel, Hozan, and others are actually conforming to a new standard: DIN 5260 which is identical (at the tip) to the newer ISO 8764-1. https://rtstools.com/jis-vs-phillips-screwdrivers-and-where-to-buy-a-jis-screwdriver/The reason these companies have changed to DIN 5260/ISO 8764-1 is because the new standard is designed to work in both Phillips and JIS screws. I have used this mod and it works very well https://goldwingdocs.com/forum/viewtopic.php?t=15547 |

if u want to pick back up the HP the cobras lose follow what Marc of FactoryPro recommends. http://www.valkyrieforum.com/bbs/index.php/topic,8248.0.htmlhttp://www.valkyrieforum.com/forum/tech_archive.cgi?read=969520This was posted by J. Orr, 3/27/1998, on the GWRRA BBS, valkyrie section. The following mods were done by Marc the owner of Factory Pro on a valkyrie that had cobra 6x6 pipes. K&N filter (w/o prefilter) Air box mod (remove plastic welded baffle) 38 pilot jet 3.5 turns idle mixture screw front needles set on #3 mid and rear needles set on #2 115 main jets all carbs this picked up 5 hp over the base run with the cobras. this HP is still down from the stock pipes or almost the same. |

(I need a picture) I thought you remove the rear engine hanger from one side only, then you can pull the carbs out from the larger opening? |

Tech manual Page 5-6 Remove the rear upper engine mounting bolts, bracket bolts and engine mounting brackets. Page 5-20 Install the engine mounting brackets, and tighten the bracket bolts and rear upper engine mounting bolts. TORQUE: Bracket bolt: 26 N-m (2.7 kgf-m, 20 fM.ft] Mounting bolt: 44 RI.m (4.5 kgf-m, 33 Ibf-ft) Yes the picture on both pages only shows the left side engine mount, however both pages do specify engine mounting brackets. I have removed the carbs and removing both brackets makes it easy and no need to play with the radiator shield. |

Shadow , Just a fyi. After the carb rebuild , move the bike outside and away from any building or car you like. Use a fuel supply bottle and not the fuel tank. Leave the tank off and away from the bike. Have a fire extinguisher at the ready. If you have a fuel leak , repair it.
I have bought two bikes that had caught fire. One of them leaked fuel and he kept cranking until the bike caught fire. It was in his garage. Got it rolled outside and the fuel tank exploded. Similar with the first one I bought. I will try to post a picture.

Wow great information, thank you all for the great tips. It would be scary though buying a valkyrie without this forum. I cant tell you guys how much I appreciate the wealth of knowledge I've aquired from all of you, thank you again.

Shadow,
There are a couple of us on here that are local to you and have offered to help you out if needed. Most of the stuff you inquire about here on the VRCC we have done and have experience with.
I have had and ridden valkyries for about 16 years, F6BANGER maybe a little longer.
If you need any help, extra hand, tools or support send me a message.
We also do some riding.
Laters Steve

Yes, thank you so much steve. I appreciate the offer. I may just be calling you if I run into problems. I'm ordering the things I'm going to need now. I will probably start actually stripping off the carburators in a week or two. I plan on installing the sissy bar I ordered and starting to paint the rear fender when I do that. So I will take off the carburators at that point. I plan on doing a black/white theme with the letter "v" from the movie v for vendetta. So I will be doing some guy fawlkes things. Not sure exactly what yet but I'll start posting pictures as I go along. Thank you so much for you help and support.

Terry, thank you for that very generous offer. I think probably the best thing is to see what jets I actually have in there first. The previous owner just said "its been rejetted." After looking over the title and such and after purchasing the bike I dont believe the guy actually knew anything about it. The reason I say this is because I noticed he had the title transferred to his name only a couple of weeks before I bought it. What I suspect happened is he won a storage auction that had the bike in it and didnt really know anything about the bike other than what he researched in those couple of weeks. If i do decide on cobra jets I"ll let you but I would have to insist on paying you for them. I'll keep you posted, thank you again.
