Bike was running like **** and would not idle. Took a look around the bike and noticed the rubber caps where the emissions hoses were taken off were dry rotted. Any others had this problem? I will give update when I put new rubber caps on. These were the "help" brand caps I bought at the local auto parts store.

 

Yup, I had that happen on the cvk .... used some marine high temp rubber things I had laying around the warehouse. The "help" brand suckers did not seem to last long for me.

 

+! exact same situation here, but different brand. Brand was "Vacu-Tite" purple package. Cap rotted off and bike wouldn't hardly run. I havn't found a good cap yet.

dan888,

Go to a nearby auto repair/maintenance shop and ask them for the caps that you need. . . . many of the products we purchase, for repairs, come with various-sized vinyl caps on them. We generally save all of these caps for later use in the trade. These caps should not fail for a VERY long time!

 

Magoo is on the money here, the marine one's I used were vinyl as well and never failed in two years....but now I got a FCR

 

Or you could put back on the emission garbage and not have to worry about rotting caps.

 

Custom block off plate made and rtv or jb weld the airbox hole.

 

I have a block off plate. The only spot I have trouble with the rubber caps is on the carb. I have some of those vinyl caps laying around, never thought of using them to block the vaccum line.

You can also drill out and tap it, then put a screw in. Or solder the top of the fitting. I have had the same problem with the "help" brand.
