That little bit of an increase in R.P.M.'s is normal when you move the throttle lever to the choke position, that is just the way the throttle linkage is designed. It is just putting a little extra tension on the governor spring as the choke linkage is being contacted and activated.
There is an adjusting screw to let you adjust the full throttle R.P.M.'s. You can raise or lower the speed by adjusting the screw setting.
The engine usually developes its peak torque around 3100R.P.M.'s, and peak Horsepower around 3600 R.P.M.'s.
Your torque is what you are really after, thats what does the work. The Horsepower is how fast it can do the work.
Tabora and O.P. should be able to give you a few good tips on adjusting the throttle cable, they have a few secrets with them. They are very easy to adjust as long as it is done properly with the nut adjusters on the cable barrel where it attaches to the throttle control.
You need a little bit of freeplay in the cable, but not too much. If you don't have any freeplay, your engine speed will change when the handlebars flex a little bit when operating the machine, and it can cause a little bit of cable bind or movement, causing a slight speed change, they are sensitive.
