... by the way it has 8000 miles on it and was sitting for about 4months with no work or care for it, it has no mods done to it andi only know of one wreak but when it does warm up it runs good well okay
More info is better.....sounds like maybe it's a case of sit-itis...start with the easy/cheap stuff first. If this were my bike, I'd start simple/cheap.
A. Drain the gas tank....flush with fresh gas and drain again/check for rust/water. (The bogging problem)
B. Fill with Chevron premium...they have an additive (Techron) which really does clean carbs and injectors...if non available in your area, put in fresh gas a nd 8 oz of Yamaha carb cleaner(not because it's a Yamaha...this stuff works better than ANY other product, period!). If the carbs are munged up a little, this will clean it up....if it's a more serious case of mung, the carbs will need disassembly and hand cleaning.
C. Drain the oil and change the filter and refill with the recommended type and AMOUNT. Sometimes bad float needles/fuel petcocks can allow fuel to overflow into the motor; causes thinning of the oil and overfilling of the crankcase. (The smoking problem).
D. Check the airbox for oil puddling to eliminate chance of oil breather problems.
If these simple/cheap fixes don't fix the problems, you will need more significant repairs/adjustments.
