Stuck, cant figure it out
Ok, so ive been searching for about a yr and a half, so no one can get upset that i ask this. I have a 93 vlx 600. Replaced stock intake w velocity stacks, and just recently fabbed/welded my own 1.75" exhaust for it, using the idea of one of the older posts on here. Ive been fighting with tuning the carbs for a long ass time, and cant figure it out. Im in illinois, so pretty much at sea level, jetted with 135 main, 45 pilots, 2-2.5 turns out on A/f screws. It sounds great, rides well and i know its a bit rich. However when i get to about 60mph in 4th gear i start losing speed. Ive tried, 140, 145 mains and i get the same thing. Cant take this out on the road much as im in the country so most roads are 55 and up.
Made sure vent lines to carb are open/ capped accordingly based off tjbrutals video, but my carb doesnt have any ports that need to be capped(theyre not there on mine). Plugs look fine, little dark on account that its a bit rich. Anyone else have any ideas? Im at a loss, about to consider selling it and get something with not as much problems.
