You must always turn off your fuel if you leave the bike standing.
It is probable, and it`s quite common, that your valve needle O rings have dried out and cracked, which allows the petrol to flow past and into the cylinder.
No 30 is what you need http://www.cmsnl.com/suzuki-dr750-1988- ... ml#results
Part no 13374-35C00. Replace both of them.

It happens with me, but mine is a sr43 so the fuel didnt go to cylinder and it was solved changing this o-ring.

It is worth changing the float bowls for SR43 bowls so that they can overflow onto the ground. At least you can see you have the problem then. there are plenty of other bikes that use these carbs so you may find another bike with overflows on.

I had the same problem with me was the problem carb float needle . When looking at the top of the needle you can not see that is consumed as it is very small . A little sandpaper can to make it right , and of course the level of floats . I bought a set of rubber O ring in the local store it cost 4 euro and all replaced only is essential that the silicone .
