94SecaII

Wow! Nobody has anything or is it cuz I'm a Yankee

I bought my 94 SecaII last October from a motorcycle enthusiast. This guy had bought it from a husband and wife and the wife rode the SecaII and her husband had another bike so I'm pretty sure that my bike was not abused (as it was ridden by an older woman). The guy I bought it from did some work to it such as: jet kit and carb rebuild (dunno what stage jet kit), K&N Velocity Stack intakes for each carb, he replaced the vacuum fuel pump with an electronic one that would normally go on an ultra-light aircraft - he said he matched the PSI of the electronic pump exactly (somewhere around 4 PSI) and also installed a Vance&Heines 4into1 exhaust. He only put about 500 miles on it and sold it to me with about 12,500. I've put 1000 miles on it so far. Last week I changed the oil and filter to get it ready for spring and summer. I asked a technician what weight oil to use and her boyfriend (a YZF600 owner) suggested I use a perfomance 20/50 weight oil. Is that too heavy? Just today I was screwin with a buddy who was tryin to talk to me and I revved the engine. It has never smoked before but as the engine was idling down, it smoked. I noticed so I tried it again, and again while it was on it's way down in RPM's it smoked again. Can oil that is too heavy make your engine smoke or is there a greater possibility that a bigger problem exists inside my block or in the valves in my heads. It has never done this before and this bike is in immaculate condition?
