4th gear
@ Marcus, Blue: Nope Im not the seller but I do have one for sale hehehe.
I have a lot of inquiries but no takers yet

so there, its a kitti 21T for anyone who is interested.
I will be trying close ratio 3rd and 4th gear soon, Its not for sale though and haven't installed it yet so I can't say anything about its pros and cons. Thanks Bros!
Question @ Marcus: I noticed that those are low speed combi bro (+/- 2.8 ) that you prefer. Of course that is with your 4th gear set, and I assume CDI and 149cc+ block. Have you tried High speed sprocket combis (2.65 or lower)? What was your observation? Thanks boss, appreciate your sharing.
