Had the IDENTICAL problem. Good compression, fuel pressure, no codes, clutches good. Ended up tearing it down and the skirts were scored as well as the cylinders. Spendy rebuild. Don't trust a compression gauge to tell you your engine is solid internally. Mine was not. Was decent cold but as soon as it warmed up it bogged 70 percent of the time. CFI plugs should have good clean color. Mine were slightly dark. Ended up being a telling tale.
Good info I have the EXACT problem. Fine when it is cool but 5 minutes into the ride it bogs @ wide open. Was you'res low on power as well? Mine is I so don't want this to be the problem but....

Had the same promblem last spring found a hole in the exhaust valve bellow and wore out exhaust valve springs. replaced both bellows and springs and cleaned valves. runs like it did when it was brand new
Mine was having similar issues after I spent a ton of money on the "fix-it" kit, ecu, tps, etc. In the end, it was bad reeds. Sucked 1 1/2 petals. Replaced the reeds and the sled has ran flawless ever since. Sometimes it may be the simple, over-looked things.
