Help....what's wrong with my engine?

[Swooperjet]

My 701 has been running off and on ty for several rides now. Absolutely no low end power. I've changed out all of the electronics, gone through my carb, new plugs, etc. It's been blowing oil through my exhaust. We took off the exh. manifold and there was quite a bit of oil coming through. The inside of my pipe is covered also.
It feels like there's no compression when I rode it, but we just did a comp check today and it's good and even in both cylinders.
I have a pro tec head that I'd put on last year.

Help....what does it sound like my issue is? Bad crank seal?

could have an air leak somewhere, u check your pulse lines from crankcase to carbs.

Have you leak tested it?

 

[BombThreat]

what are the comp numbers?

i think, due to previous test's my gauge is off by about 35 to 40 pounds, it is an old ass gauge. they were both at 145. i should be about 180.

By "going through the carb" does that mean you put a rebuild kit in it?
Any exh. leaks filling the engine compt. with exh?

Sorry...haven't been on the board for quite a while. Thanks for the input. Turns out that it was a bad ebox seal. Switched over all of the electronics into a new box and bingo. Also added a MSD enhancer, and I likey!!!! (had already tried two stock cdi's so don't think that was the issue, just a bad gasket on the old box)
Anyway, 2 weekends in a row now with the ski running kick ass! First time since last December.
