Reassembling carbs for my '81H and am using solid metal needles from carb rebuild kits I bought for a '79SF in lieu of the viton tipped needles that were in my carbs. One of the carb tips advised against using the solid metal needles because they might jam. I did notice that the new needles do not have the tiny wire bails on them to attach them to the float tang like the viton tipped needles did. Anyone have any experience with this? I don't want to have to disassemble the carbs again due to a sticking needle issue.

The needle seats are different shaped I believe and the metal tipped ones will not seat properly. Get the proper needles.Nathan

Your original needles should work fine unless the viton tips are damaged in some way. Just wipe any white residue build-up off the viton.81H Venturer1100 "The Bentley" (on steroids) 97 Yamaha YZ250(age reducer) 92 Honda ST1100 "Twisty"(touring rocket) Age is relative to the number of seconds counted 'airing' out an 85ft. table-top.Comment

the viton does get hard over time though and if they are original they are most likely hard.Originally posted by motoman View PostNathan

Take you originals and wipe them on a rag soaked with carb cleaner. Wipe toward the tip and rotate to make sure the entire surfance is cleaned.Originally posted by natemoen View PostSkids (Sid Hansen)

The metal tipped ones might be narrower and a different height so you might run into issues using them in the late type seats. I could care less for those retaining clips, they are more a pain than they are worth. If your float drop level isn't too low, you shouldn't need them anyway.

carb question
Thanks for all the advice, guys. My old viton needles look pretty good (the bike only has 13,700 miles on it) so I'm in the process of reinstalling them. Hard to be positive, but the profile of the metal needles does appear to be slightly more pointy than the viton ones. I need to get these carbs reassembled and back on the bike ASAP. Will let you know how it goes.
