j/k.. There are a few good threads on jetting that will explain allot. Go to the search box and look up jetting. You will need to re jet if you haven't already for that pipe you have.. Its not hard to do and one of the most important things to know.. My suggestion would be to read and read it again then read it again until it completely makes sense..

nope, you do not rejet to go faster, you rejet to match "go faster" mods such as pipes, airfilter, airbox ect.
anything that increases the air flow into or exhaust out of the engine requires the jetting to be richened to match that extra airflow and keep the air/fuel ratio correct.
and what main jet ?
i believe toomey suggests a 310 main, and the airscrew will need adjusted
you did plug chops to confirm ?

Toomey B1 is #310 with an aftermarket air filter with holes drilled in the air box lid.
Take the lid off and you may need to go bigger.
Whatever way you go you will need to plug chop to confirm.
Before you make the plug chop run it is important that the float level is correct, the idle is set correctly and there are no air leaks in the system, otherwise the smoke ring may lie about the AFR.
WHEN ALL OF THE ABOVE ARE CORRECT PROCEED WITH THE FOLLOWING.
Warm up motor to operating temp.
Fit new B8ES plug, ride WOT through the gears and hold WOT in 5th or 6th gear for 10 seconds, or as long as you can safely.
Switch off the motor and pull in the clutch, apply brakes to come to a stop quickly.
Take the plug out and replace the old one for the ride home.
Carefully cut the threaded end off the plug to expose the insulator.
There should be a smoke ring of a cardboard or biscuit colour around the insulator.
If it is non existant or a very light colour, you are lean and require a larger main jet.
If it is a lot darker you are rich and may go down a size in main.
I prefer to run a little on the darker side, I may loose a little power but it is worth it for the peace of mind that I won't need a rebuild so soon.
This is a good to ride plug.
This is what I like mine to look kike a little rich.
You have to get up a reasonable speed so that you can get the motor to pull strongly.
Then hold it Wide Open Throttle (WOT) for 10 secs or as long as you can.
The idea is not to get speed but to make it pull strong at full throttle to get onto the main jet circuit.
I find I can safely do it on a short run by applying the brakes some.
If you have not enough room you can use 4th or 5th gear with good results.
