Recently my brother who has a 1979 GS750 told me that his air filter has a foam, fitting on the top to seal it to the box, also it has a rubber snorkel on the back of the box, my gs850 has neither of these tell me where to buy one or if i could possibly buy one from someone on here
 
The foam on top of the filter can be replaced with weatherstripping foam from the hardware store.

The snorkle can not be purchased separately, you will have to find one from a member or get a completr box that has one.

Oh man change the font color! my eyes...:eek:
 
I bought a snorkle on ebay. & used 3/16x3/8" storm window foam to seal my filter & airbus.
 
Hi,

Have you seen the 'airbox sealing' and 'air intake repair' guides on my little website?

You might have better luck looking for parts in the 'Parts Wanted' and 'Parts For Sale' sections of the forum..


Thank you for your indulgence,

BassCliff
 
Thanks Bass hey while on the subject, do you know if the cv carbs on the gs850 have clip positions on the needles?
 
Stock needles only have one clip position. Some people have shimmed them with tiny washers to smooth out a mid-range flat spot, but that's all the adjustment there is.
 
Well that sucks, my bike has aftermarket exhaust and I have changed the main jet as per the Vance and Hines recommendation but I cannot runn wot as it will run up until about 7k rpm then fall on its face

What size jets are in it currently and what changes have you done so far?

Eric
 
I re-sealed the air box and cleaned the carbs once, also installed 120 mains and that's it, I think it may have really clogged up needle jets
 
Take the carbs apart and clean them correctly.
At your altitude those jets would be close to ideal or slightly rich depending on the exhaust restriction.

www.cycleorings.com is your friend. ;)

Tomorrow I'm gonna clean the imulsion tubes and also the pilot jets to see if that makes a diffence

Is that a really quiet Vance & Hines pipe? Keep in mind that "quiet" = "restrictive".

My son's 850 has a rather quiet pipe. We don't know for sure, but are led to believe it might be a Jardine. We have 120 mains in there, and it does OK. If your pipe is less restrictive, it might need 122.5 or even 125 mains.
