For what it is worth........
at best a kit is going to get you in the ballpark. There are several factors that drasticly
effect jetting on two strokes. Fuel used and oil choice being two of them. Exhaust as well S/A or silencer.
If ballbark is not OK, then there is no short cut to getting it right.
Many OEM needles have their own number system and do not share technical info.
Needles are measured each 10mm. You need to know where you are starting, in order
to figure out where you are going. Next is to figure out where in the power band does not work correctly. Some correction can be made be made with jets. It is when you get out of you adjustment range with the needle clip that a new needle may be in order.
The Needle is part of the fix. Many try to "jet" around the problem or feel that the needle is the magic answer. Oh yea, don't forget the slide. This can fix many problems being clean down low. Some own tractor two strokes and don't know it. Businesses that
offer kits are providing a needed service by getting us into the ballpark. However,
each bike, each rider, each situation. Basic stuff here equals max power to the ground.
Colors are used for certain applications. But my grand daughter gets mad at me when
I go outside the lines.
