1994 K75S Unblocking a blocked tank vent?
I believe one of my tank vent lines is blocked or somehow restricted. If so, it's probably what has been causing the high pitched chirping (subject of another current thread),
I have tried blowing through a hose attached to the vent pipes protruding from underneath my tank. The rear one lets some air in but the forwardmost pipe is blocked.
Anyone have any ideas on unblocking it?
I already tried #12 gauge copper wire; it'll only go in about two inches before it must hit a sharp bend or something.
I'm going to try blowing some air in with my HVLP turbine to see if that makes any difference (probably not but it's the only other idea I have at the moment.

[QUOTE=deilenberger;817801]I don't think it's a new problem.. :whistle Have you noticed a "whoosh" when you open the cap to fill up? That's the usual sign of a plugged up vent. As the gas is pumped out, and no air can get in, a partial vacuum is formed.. and the fuel pump has to work harder (causing it to chirp perhaps?)
To clean out those sort of lines, it's hard to beat weed-wacker line.......[/QUOTE]
Yes, I think you probably nailed it again, Don. Our housemate thought it also might be the source of the chirping problem and told me to open the tank the next time I heard it screeching to see if that made any difference. Believe I mentioned this in my chirping thread a few days ago but anyway I am guessing that your hunch/his hunch/my hunch is correct. I have almost always heard that whoosh every time I stop for gas and open the tank---so often that I thought it was normal!
I think I still have some red plastic weed whacker line around here somewhere. Although my wife and I will probably be making a day trip tomorrow in another vehicle I may try to see if I can clear the vent before we leave. Then I would almost be assured of perfect performance or at least the bike would be a whole lot closer to normal than it's been for the nearly four years I've had it (Oct. 1st "birthday"). Will let you all know the outcome as soon as I can.
It will be quite a relief to have the bike running well (poss. better) again and the fall riding season around here is nothing short of fantastic.
