Engine hard to start when cool

[KawiSXi750]

I just had my cylinders ported, and bored and installed new pistons and rings. When the motor is cold it takes a little effort to get it started and you can't get on the throttle hard without it stalling until after about 5 min of riding. Kinda have to feather the throttle when starting out. I'm guessing its a jetting problem but wanted to get other opinions. It's a 95 sxi 750 bored 1mm over, running about 3 deg advance, between 175 and 180 psi on both cylinders.

Yes, You can jet it a little richer, It all depends also how the cooilng is set-up, single or dual lines and what's the water temp you normally ride in...P.S. Primers work well for cold starting.

Yup, a primer is going to be installed. I ride in warmer water (approx 70 deg) most of the time with a single cooling set up. My main concern was the bogging on the low end for the initial part of the ride. I'll open er up some more on the low jets. I guess we'll see if my stock jets are gonna be big enough. Carbs are not my strong suit.
