I have a 1998 superhawk with 16,000 the carbs have been jetted with a dyno jet stage one kit K&N air filter and a set of D&D slip ons I wanted to go down one tooth in the front or make it easer to wheelie but i still want top end and make it streetable what should i go with some one told be down one in the front will be perfect

 

Here we go again........

 

Maybe try a search this topic has been debated to no end.

 

My 2 cents is that 1 down in the front is a good improvement. Cheap and easily reversible. You can always try it and go bigger in the back if you want but this is the simple first step.

 

I think you left this out, so I will add it for you: I plan on changing my oil soon, what type of oil is best?

 

Well, there is a consensus around here that -1 on the front sprocket is better than stock. Some consider it optimal.
Give it a try. You'll probably like it.

Then get rid of that K&N filter.
