If your bowl isn't full , it's not gonna run right. Do you honestly think that carburetor, those jets , off the showroom floor, ran like that?

JOG , I think he will have to go to bigger jets if he 's going to get rid of that mid range sag . Yoshi had a similar filter and muffler set up on his bike and used a 55 pilot ,152,5 main and two #4 washers for the spacer mod.( their elevations are nearly the same) I don't think mpg will be good ,but it may run better . If he can't live with the bad mileage then it's time to think about a better muffler and smaller jets.

I'm not to concerned with the mileage just want to try to optimize the throttle range with the air filter and exhuast set up i have. It struggle to get up to 50mph and is a dog and stutters on hills.

Here's the update. 55 pilot, 152.5 main, cleaned carb and rebuild, 3 of the #4 spacers for the white spacer mod, new idle mix screw at a little over 1 turn out from the full closed setting and adjusted the float just ever so slightly and now I feel like a complete jack a$$ because it runs about 90% better. Thank you all for every tied bit of ideas and knowledge. I'm hitting 70mph pretty easy but still have a little stutter ad full twist. It really is a huge difference just from a few hours ago.

Ok so I did some back tracking today. I pulled carb and verified i ha e 50 pilot and 150 main jets, blew it all out with air, adjusted need to the spacer mod position, 1.5 turns on air mix and double checked float level. Now i had a theory, the slide is vacuum operated and the slot in the top of the i take side of the xarb is what opens the slide........ big air filter and 10 inches of silicone tube for my i take creats very little resistance.... so I pulled the after off and left the tube, put tape over 2/3rds of the opened of the tube to create less Opening and man this bike has changed. I can pull 80 with with some left to twist. I can pass cars and it'll almost toss me off when hitting 4 and 5th gears. Time to get an a new filter setup or just get a small ryca or such cone. Thank you all for bearing with .e and giving me input. The bike looks and sounds the way I want and I'm friggin stoked

Don't get stoked to soon! Changing the air filter will do little to effect how the bike runs!(you'll be right back where you started) When you put tape over the inlet it cut down the amount of air drawn into the carb and increased the vacuum in the carb body, which pulled more fuel from the jets ,which should tell you your jetting is way to lean . That's your problem! not what air cleaner you use. I'll run this by you one more time 55 pilot ,2 # 4washers on the needle ,152.5 -155 main jet. Don't expect good mpg.

Make sure all important connections have been inspected too. No harm in unplugging say the signal generatore at the plug and spraying with electrical contact cleaner. I found that on top of a major fuel issue that there was this other smaller thing which I didn't discover till I replaced the carburetor which fixed the main problem thus then exposing a curious intermittent fuel starvation. Turns out that cleaning the contact as above fixed it.

Posts: 59	Re: Wide open woes Reply #29 - 03/02/18 at 18:07:38 I fabricated a mild restrictor plate for the air tube, the jets under the slide diaphragm have been put back to stock. Have risen the bike a few times yesterday and today and it's running great. I will be playing with the main jet a little over the next few days and try to find the sweet spot
