No problem!! have fun riding and be safe. I just went through a $36,000 surgery for being not so safe and it was not worth it at all. Be very aware of the surroundings everytime you go riding because things can change and ruin your day.

If it doesn't change things, you are probably running lean. It should run better though if it is lean when you pull out the choke. The best way to tell is to test your plug, but alot of times the choke will let you know. I would try a bigger main jet and see what happens.

If It is white, it is lean. It should be light brown to tan color. Is the plug fairly new and are you doing a plug chop?? Ride at full throttle for about 1/4 mile cut the engine off without changing the throttle from full until after the motor is off, not stopped. In other words, don't use any idling or anything, just cut the bike off at full throttle and coast to a stop and check your plug. Is this the method you are using and is the plug pretty new??

A 180 main should be just about right for that setup. You want to be a little rich and then adjust from there. I am running a 200 main with all the mods that I have and it runs real smooth throughout the whole range.

OK, it is my personal opinion that either one of two things are going on with your carb. A) You're choke is out of adjustment. B) You are way too lean. The reason I say this is because when you flip on that choke, it should really change things. There is quite alot of gas that comes in through the choke and If it isn't bogging when you use it there is something wrong. First of all, make sure your choke is adjusted/working properly. The easiest way to do this is to remove the carb. Look inside the bell of the carb. and while activating the choke you can see the plunger through the hole that supplies the gas through the starter circuit. A flashlight is the easiest way to see things. When the choke is full on, you shouldn't see any of the plunger, half you would see exactly half of it, off you will see all of it with the hole completely shut off. Now after you verify that the choke is adjusted properly, put the carb back on and try things again. Try to use the choke in other throttle ranges and see what happens, the bike should bog down and run like crap because it is too rich. This is also what should happen when you do it at full throttle. Let me know what happens.
