Ok so another newbie question but ive found asking here is the fastest and most accurate way of finding quality info out so here is another,
My 81 750k is my very first bike so i have nothing to compare to. Ive noticed that my acceleration seems to be sluggish around 2500-5500 in 1st,2nd gear.. Ill give it the throttle and hear the motor and Rpm's increase but the acceleration just doesnt seem to be what I think it should? Understanding its over 30 years old and only a 750 yada yada i got it- Is it dirty carbs/something else or normal for these?
As always THANK YOU to all who respond!
P.s. If it is carbs, is there any method of cleaning that doesn involve total restoration and a migraine!

Motorcycle carbs are not like a car. You do not need to completely strip them and it can lead to problems if you do not know anything.
One of the most critical parts in a motorcycle carb is the float needle.
Just replace those every two years or so.
But .. the idle jets can be clogged up . Especially if it has been sitting around.
It could be something other than the carbs also like the timing and the points and condensers.

I like vintage bikes because they take me away from the clutter of technology that I work with everyday and back to a simpler time of mechanical elegance and simplicity.. "ninadm"

If you don't feel up to cleaning your carbs yourself, you can always send them away to get professionally cleaned. There are people that specialize in cleaning the cb750 carbs. One of the best manuals for cleaning them that I've seen is written by a carb cleaning service.
