those jets
Are at the dealer. He gave you Honda part numbers.
buy a 15 tooth sproket for the front
Do that and don't worry about the rear , it's fine as it is when you run the 15T front.
would need to get a new chain too
No.
Hey, I have to ask you....are you stoned or something ? We have given you very ,very clear advise , directions, part numbers but it's like nothing is soaking in.
If you want help here we are glad to do so, it's what we do.
However, if you're all over the board with your questions (You sure are), and disregard or skim read what we are taking the time to post in order to help you(You must be) you're going to find your future questions falling on deaf ears.
Lastly, while this isn't english class a little more care in your spelling and punctuation would sure make your posts easier to read.
Others are giving you properly spelled,easy to read answers, how about extending the same courtesy ? Doug
