Hi guys, I'm a long time reader on this forum... been a great resource and truly appreciate everyone that helps out.
To start off, I just got done doing a fresh bore, new pistons, different carbs, different head. The head I traded my stock one for, it's a stock head thats been shaved but I have no idea how much. I put all this together and it starts right up, and anything under half throttle it runs like a top. But right when I go past half throttle it's a straight bog. Anything past half it bogs, like a switch. It's bad
My bike has the following.
Fmf gnarly pipes
Vf3 reeds
Keihin pwk 28 flat slide carbs
K&n pods with outerwear
Stock crank as far as I know
Am at roughly 200 feet above sea level
I run non-ethanol premium fuel 92 with torco gp7 mixed at 4 ounces a gallon.
I tried jetting it all day yesterday had no luck. I had a 50 pilot in it and had mains all the way from 152 to 162 and I noticed no difference in the bog going through each one. I did notice it ran a little better when I pulled both the chokes and pinned the throttle through the gears.
Any help or suggestions are highly appreciated, I'm kinda stuck where I'm at. Gonna very throughly clean the carbs tomorrow morning and do a leak down test if I can get the parts together to do it. I would also love to do a compression test to see if I need higher octane gas but I don't have access to a good one, I have a harbor freight one says I have 120lbs in each and the autozone rental says 110 in each.... I feel there's more than that in it when I kick it. But who knows
Thanks again guys!!!
