The jets on my carbs are 127.5 and im about to throw a 4-2-1 yoshi system on it,
Do i dynojet it or stick with just changing the jets ? and what size jets ?
I have put some races cans on it and it was getting too lean at the top end
and loosing power so put the standard ones back on.

Do not use Dynojet. Factory jet kits are better. I think I used the stage 2 kit on mine with similar mods.

Been looking for factory jet kits im in the uk so running the 40mm bst carbs and the only ones i can find are the US 36 mm bst kits, so may have to go down the dynojet route or try just getting bigger mikuni jets
