Hi, I have a newish RS125 (1200km) that due to some non standard circumstances (buyer puchased bike new from a dealer in another state) had the performance kit installed (at 0km not at first service) but was not jetteed to suit. Bike is one of the strange ones... it's a 12/2009 model but with the older denso CDI and PHBH28 carb. Can somebody who got this pack installed after the first service and who has PHBH28 carb tell me what size main jet was fitted by the dealer? The stock main jet in my PHBH28 was a 128. I'd really appreciate it! Cheers.
