Hello..
I recently sold my GSXR 1k and bought four dirt bikes for the family. I raced MX a few times when I was 15 and then stopped riding due to location. I enjoyed this as a kid and I am slowly getting back into track riding.
I was not looking for any upgrades but I came across a sweet deal on a jardine RT-4 full TI Exhaust. Now I am worried I have to rejet it. I have a new CRF450R. Everything is stock. I just ordered the pipe today.
What type of jet kit should I buy? Should I take it in to have it rejetted or is it easy enough to do myself. As a kid I remember just unscrewing a jet and tapping a bigger one in. Not sure if it is the same.
Any advice on this would be great. Thank you in advance!
