Well, not a lot of riders are willing to learn how to take apart carbs. I did, and I thinks it's a lot of fun. Can't say for sure that the service manual would help. What is the goal, to restore stock jets to the carbs? Dyno Jet provides their specs for their kits online. I can't find the Clymer manual for my Nighthawk, so I can't say if they provide that info. Maybe ServiceHonda.com? I don't have a lot of specific info, but I've been told that DynoJet kits have more tapered needles, and Factory kits are not tapered. They just come to a point. If you look on the side or top of the jet, the number wil be stamped into it, along with the manufacturer, I think. I know that Keihen (sp?) has a "K" looking thing before the number.
you rock! i have been going nuts trying to figure this out! my boss/friend/former motorcycle mechanic is helping me with this task. and i don't want to open these carbs up until i know every thing! I have a funny feeling that the bike has dyno jet kit. it has a K&N air filter and an after market exhaust so... well it had to have been jetted and i'm going to guess it was dyno jet. we are going to start taking it apart in two weeks, wish us luck!

If you don't even know whether or not it is jetted, the easiest thing to check is the needles. All OEM un-modified needles will have only ONE position to set the height of the needle. All jet kits will have several grooves and an "e" clip that fits into the groove to set the height of the needle. If you can get to the carb top covers without too much difficulty, take one off and pull the slide out. I can't say for sure how to get the needle out, but my '98 F3 has a plastic piece that snaps down into the slide to hold the needle down. It has a threaded hole in the top that fits the carb cover screw. I screwed it in a few threads to give me something to hold, and pulled it out. Never seen VFR carbs, but maybe similar. Please feel free to ask any other questions. I have no experience with VFR carbs, but I have recently found that all carbs are basically the same. As long as you keep track of the parts and put them back together properly, it is difficult to mess up. Good Luck! Keep us (well me...lol) updated.
well the bike has to be jetted, after market exhaust and k&N air filter. but i haven't had a chance to dig down that deep. so far just changed the spark plugs checked the wires and the usual stuff. did a once over on the bike to make sure that nothing was leaking. in two weeks we should start working on the carbs. the gass was pretty stinky so i'm going to guess that the carbs are going to be all mucked up as well. but i'll do my best to post pics! just because, from a mechanical engineers point of view, carbs are really interesting! but thank god for ECU's and fule injectors! new pipes! just change the programing! and off you go!
