This may be a silly question to some, but to me its not cause I dont know for sure or not. Today I rode for a bit and got home. I shut the bike off and was just going over my bike like I always do after riding it. I like examining my bike for new problems. I took the oil dipstick out and looked inside and then I smelt a strong odor of gasoline coming from the oil tank. Is this normal and is it normal to have gas that has entered the oil tank area? Is this common? Also, when I am letting it idle and I rev it up it shoots out a little of smoke and never noticed it before to do this. It did not do this before me discovering having a intake air leak. I tightened the bolt only and did not replace the gasket yet either. I have been fooling with the carb screws to try to fine tune the carb. I have drag pipes on the bike in case someone needs to know. Please just hit me back with some feedback. Thanks so, so, so much for all you all have done for me so far. Im ever so grateful!!
