Just looking for some advice on my new set up I’m building. Need some suggestions for roller weights - bearing in mind the over sized trans pulleys.. also in need to jet that massive 28mm carb! Yamaha Aerox The SET UP: Stage 6 Mk2 70cc raging 0.6 squish & a few mm advanced on stator plate(portmatched) Jasil extreme crank Stage 6 c4 metal cage bearings & seals Pwk stage 6 28mm carb Stage 6 viton reed block carbon fibre Motorforce 28mm racing air box RMS High flow Manuel fuel tap Diaphram fuel pump Polini boost bottle Motorforce racing Coil 32k volts Stage 6 oversize rt transmition pulleys Jasil 13/43 primary gear kit Jasil 14/41 secondary gear kit Bosch 12v water pump Plus loads more.. this is most of the stuff that will effect rollers and jetting
Wouldn't know without starting it and riding it. The boost bottle doent do anything by the way. Thats going to be awesome though. Still running an oil pump or premix?
Yes it’s premix, I know the boost bottle doesn’t do much but it can help when slamming the throttle after decel I believe.
I have done a stage6 race build but not with a carb that big or the over size pulleys So prob won’t help you knowing my set up Sounds like a serious build though! Any pics?
Any input is greatly appreciated not many pics yet but will be documenting the full build and should be posting to YouTube. Will keep you updated Here’s a couple of random pics
You have way too much gearing, just put the primary 13-43, as for jetting start from 160mainjet, rollers try 3,5 but your main problem is your ignition, you must get innerotor ignition.
