hey. today i did the oil block off mod, and put new 32:1 gas in there. now alot of white smoke comes out of the exhaust. why? also, there is a small oil leak from where the engine sprocket is. is there a seal that could be bad? and if so, is it easy to replace?
white smoke. why?

sounds like your burning gear oil. white smoke is a sign that ur burning gear oil, could bee a bad crank seal.
when its running and warmed up to running temp put your hand at the end of the muffler and rev it up a little a couple times and see if your hand feels oil and u also can look in side of the pipe when its not running and see if it looks real oily. if so than u are mixing rich. or it could also be a crank seal going out on u but if it didnt do it before then prob not white smoke is a sign of bad crank seal, also when it warms up does it go away a little bit??
and your leak from around the sprocket it just a seal kickstarter seal shifter seals always wear out and leak cheap fix. but i would also look at the case to see if your chain broke at one time and may have hit the case and cracked it. this happens time to time but more than likely just a seal.
actually just since i did the oil block off today did it start smoking white. well i cant tell if it is completely white or has a bluish tint. but still with my second question, is it easy to replace the sprocket seal? where can i get it? i have looked everywhere and cant find a "sprocket seal"
its black and sooty. i think i just mixed too rich. but still curious about sprocket seal
u can order it here if u are have ing a hard time finding one or u can get a kit off ebay that will have kick starter seal, shifter seal,this one and a few more.1998 Yamaha BLASTER / YFS200K OEM Parts, 1998 Yamaha BLASTER / YFS200K OEM Motorcycle Parts - BikeBandit.com its part # 26 if its the one behind your sprocket its like 5$ or u can go to the dealer ship and get one if u only need this one.

The seal behind the sprocket is called an "oil seal" not a "sprocket seal". It is a very easy fix. Once you get the sprocket off, it took me like 5 minutes to replace it. Just remember to put tape over the sprocket shaft and oil the inside and outside surfaces of the seal before you try to install it. The tape is to keep the shaft from tearing up your seal.
what gaskets would you need to replace all the seals
oh and did you block off the oil injection to the carb? just a thought this is something I forgot to do
