Thanks for the compliments. It's taken me months to get it that clean. The gentlemen I purchased it from kept it outside all year long, and only road it maybe 3 or 4 times a year. Those poor carbs were a complete mess when I took them apart as they were gunked in ethanol corrosion (green and brown). Plus he lived on a farm and the bike was filthy dirty, and I mean filthy! I use a spray/wax cleaner from the autoparts store...can't think of the name. I've tried the stuff sold at Honda, but it sucks...leaves a white streak and really doesn't shine all that well. Once I'm done with the mechanical side, then it's time to pull all of the covers off, and I'm going to paint it (I used to do paint and body work); same color of course.Good video, beautiful and super clean bike.
When you check the vacuum hoses make sure to squeeze, bend and manipulate them as some splits and cracks may not be visible otherwise.
Also pay attention to hoses that have a preformed bend as they can collapse along the inside radius of the bend.
I've replaced nearly every vacuum hose on the bike except the PAIR system hoses, and the three hoses that go to the IASA Valve. I also changed the troubled hoses under the carbs as one of them had a hole at the bend.
I think sometime tomorrow I'm going to yank the plugs off and perform a compression test to make sure none of the valves are sticking. I've seen this happen before although on automotive engines. My 5.7 Vortec misfired a lot and I thought it was worn rings. I yanked the engine out and rebuilt the entire bottom half first. When I got to the heads, that's where I was stunned. Half of the exhaust valves were caked with ethanol corrosion; it's a sticky gew that stretches like cheese when it's wet, and smells like burnt corn when you use a drill and wire brush; the crap is very hard to get off. Normal carbon buildup is easily removed with parts cleaner. But ethanol corrosion has kind of like a tacky candy-apple texture. And because the gentlemen I purchased the bike from used ethanol in the bike, and left it sitting up for more than a year without fuel treatment, I wouldn't be surprised if the valves are not closing.
The troubleshooting continues.
