Carb Sync Update & fork seal questions

Postby new82 » Wed Dec 14, 2011 5:35 pm



Well, I finally got my carbs pretty well sync'd within 1/2 lb of each other any rate, and it makes a world of difference - even makes the bike feel lighter. ran it up on the uphill side of a bridge from 1500 & it pulled smooth & strong. started missing a bit above 7k, so I upshifted, but was smooth & strong everywhere else. I used a single harbor freight vacuum gauge with a 4 way valve and a medicine bottle for a plenum. Next time I'll use a bigger plenum bottle, because I still had to dampen oscillations with the valves.

Next project on the agenda is a starter overhaul per the DIYs.

Has anyone used any kind of seal conditioner with any success in the front forks. I changed the fluid about a month ago & put ATF in it & they leak a pretty good bit. The oil I drained out before filling was an oil, not ATF, and was thicker than the ATF. I was thinking of using something like straight 20W & possibly some kind of conditioner. I'd rather not replace the seals yet.

Congrats on the carb sync, it really does make a big difference.

On the fork seals, it has been my experience that once they leak they always leak.There is no real bandaide fix. Just go ahead and change the seals, They are not hard to do and are not very expensive. ATF is what the book calls for ,but I prefer a firmer ride and use 20wt fork oil. Do not use anything other than ATF or fork oil.
Ride safe, Todd

You might try cleaning the seals there is a "tool" that you stick down between the seal and the fork tube and it will "grab" the crud stuck in there and pull it out..if any is there, worked for me..no more leaks.. I made mine own from film negative strips, or a plastic bottle or even a coke can or you can buy one..like below..Google seal mate and you'll find the site..it's $6.

Thanks RB,
I'll try making a cleaner out of one of those thin fake credit cards like AARP sends you & try it out. Not expecting miracles because I have no idea how old the seals are that are in now, but they didn't seem to be leaking or not as much before I switched to ATF. I'll try cleaning seals change to 20w fork oil & see what happens.
When I do get around to changing them, any recommendations as to the LEAK-proof seals & boots vs OEM ones?

Most Oem seals have lasted for 20 years or more. If you are going to replace the seals do the bushings too. If you don't your seals will leak sooner as worn bushings allow the tubes to move laterally. Also the seals look like they can be installed either way ..but there is a top and a bottom and it does make a difference..look carefully at the seal lip when you take the old ones out..and match the new ones there is a slight bevel.

RB is there a video or step by step to replace the seals and bushings? My '83 Interstate also is leaking from both front seals... and it was recomended by a cycle shop to replace. Any help wwould be so much appreciated. I have no mechanical skills what so ever... :o but really want to learn to work on my bike that i had for 1 year now. thx

Note 1000 and 1100 are similar but there are differences in how you separate the tubes from the legs.
