OK jets in carb are Mikuni 40 which is standard , I have checked all my spare Pilot jets and they are also standard 40, also checked and Dynajet stage 2 dont supply pilot jets anyway but seems that tuners reccomend putting in 42.5 pilots if off idle is lean or too many turns out on airscrews are needed ,, so as i have several 40 jets i want to drill them out for 42.5 now I need to find tiny drill sizes ????

Have tried buying 42.5 Pilots but no one has stock tried NP and Allens , any the prices on Ebay are stupid £38 for a used pair monster 900 pilot jet jet
