Z1000a1 - Carb Rejetting

#1 PostAuthor: angeleddie » Sat Jul 18, 2009 7:13 pm

Hello People,

I am rebuilding my 1977 Z1000a Carbs (26mm)

Looking for advise on jetting, I have a Harris 4/1 & K&N type filters

main jet is 107.5 at present & circlip on jet needle was in 3 position

Would appreciate any advice on using a bigger main jet & raising the jet needle?

thanks

Likewise 117.5 on mine but on 28mm carbs and 1105 when it had a Harris and filters. 26mm may need a little less maybe 115 but 107.5 is amost certainly too small.
