It could be coincidental, but after about 15 minutes of warmup, my Silverado gushes oil from the right side when throttling at idle. I can ride it fine for about 15 minutes, even with occassional WOT, but then at some point you throttle and it gushes, coming from where the silver oil tubes join the right side of the bike and from somewhere on top of the rear cylinder that I haven't yet identified.

I was so proud of myself too after successfully doing performance mods. The bike runs great. Put on a ProPipe, Barons BAK and ported manifold. Rejetting worked great and there's no backfiring whatsoever.

I'm truly bummed. I don't think taking all the pollution control stuff out during AIS blockoff would have caused this. What do you think?

As per Road Star Clinic instructions, I left a rear cylinder center-mounted hose attached and aiming at the ground. The manifold nipple is plugged, as is a carburetor nipple formerly going to the AIS. Another real cylinder right side-mounted tube is going to the Barons BAK.

I'm really baffled, that's why I think it may be coincidental. But I wanted to get some feedback from you guys before taking it in to the dealer.

There is a breather tube in the top of the valve cover on the back cyclinder. Based on your description, take a look and see if maybe you knocked that loose during the AIS'ectomy. Also make sure you did not loosen the oil tube banjo bolts during your operation.

Very interested in hearing about this ... once my MAXAIR shows up I plan to rip the entire bike apart AIS, smog and all.

CRASH

Crash,

There are two nipples on the top of the rear cyllinder. The one smack in the middle has a hose venting to the ground. The one on the top front right side goes to the Barons BAK.

1) Is either one of these the breather tube you are referring to?
2) Where are the oil tube banjo bolts you are referring to?

Thanks,

Peter

Those are the breathers I am refering too.

The banjo bolts for the oil tube are actually on the left side of the engine, so I doubt that is the problem since you say the oil gushes on the right. WIll look close again and see if I have any more bright ideas.

I'm confused and need a pic!

On the right side (when sitting on the bike) there are two chrome oil lines going from under the cover (under the seat) to the lower part of the engine (by the decompression valve).

There are also two black hoses coming from the top of the rear cylinder. The forward one runs to the back of the air filter.

Which ones are spewing the oil?
