Ok, frustrating day trying to get these carbs set up right.* I started with stock carb set up and I have fabbed dual HMF mufflers off my vforce and used the stock headers. Ran ok with a pause on accelaration and* popping decel. Thought ok just rejet.Rejetted with 175F and 170R. Turned the fuel screw out a 1/4 turn. Ran like crap when I hit 20 mph.* Scratched my head and tried running it with the air box lid covered slightly and it ran worse.* Opened the lid slightly while running it and it would hit a spot every so often where it ran great. So I thought ok needs more air and went home to drill 6 1 inch holes in the lid (Worked great on my V-force). Rejetted again to 190F and 190R turned fuel screw back to where it was stock,* 1 9/16th back and 2 1/16 front, went out and ran it and ran slightly better than before.* Tried running with holes all covered up and uncovered one hole at a time and no difference. Stock was way better. At this point I am ready to put the stock muffler back on and put the stock jets back in. WTF is up with this carb set up? How is it different from a V-force 700 set up? On the 700 engine I ran a K&N with 9 holes open and HMF duals running with 185F and 180R.* It ran great.* I have read Hunter works posts and am well aware of what is being said about making changes to air boxes and changes to the carbs. I can see his points, but believe there is a lot of potential with these common mods.* Maybe I need to put a lighter spring on the slide, I don't know.Maybe Mickey from Four Stroke tech or someone with experience with the v-twin engines could give us some guide lines on jetting, fuel screw, air box mods and exhaust. I am a simple shade tree type of guy and need help!
