I'm not going very deep.
Just decent stoich by plug chop indications.
It's just a street bike. Back and forth to work, around town and freeway cruising.
It's a 1983 Yamaha Venture:
rated 99 hp at the crank.
I've just installed VMax heads and cams, the Vboost is going in too, all controlled by an Ignitech controller. Coil on plugs are also going in. The transmission has been swapped for a 2002 royal star venture transmission and the rear differential is also from a VMax. Still using the stock down pipes and collector box. Mufflers are from a Yamaha R1, so essentially the same as a set of "slip ons". Likely less restriction than the stock venture mufflers as the R1 model these muffs came from was rated around 170HP, they should flow fine on my bike, but will also mess with the jetting.
I'm hoping for somewhere around 130 crank and/or 100 RWHP. VMax is rated 145 crank, but hte exhaust is different and it has a skootch more compression (about .5).
Its highly unlikely the stock carbs will be right for the modifications (venture uses Mikuni 117.5 main jets, Vmax uses 155-160), hence the need to rejet. Like I said, not fussy. Just going to do plug chops and get it "in the zone".
Biggest concern is that I don't go lean.
I'll likely have to fool with needle height, float levels and pilot air jet sizes as well to get it dialed in.
No big. Been there, done that.
