Yes that is a very good idea[url=https://classicgoldwings.com/forum/viewtopic.php?p=181386#p181386:2dndruec said:chuck c » Wed Sep 28, 2016 9:21 pm[/url]":2dndruec]
Some puddle room keeps small amounts of liquid gas from running into the cylinders. As the carb needs to be dialed in, I think that's a good idea. I've already dumped quite a bit of raw gas into my cylinders with the previous experiment. I've even considered adding a small fitting and bit if clear tubing on the bottom so I can see if any liquid is collecting.
The runners are beveled to point roughly towards the center. I don't think it will help flow a great deal but it's got to be better than a nearly right angle flow as it would be if the tubes were flush. That will also spread and disrupt the pluses coming back from the intake valves when they close. They won't be able to go down another runner.
Theory and perceived performance holds the fuel charge "bounces" back as intake is closed. Opposite cylinders is on exhaust stroke so draws it that direction as it begins the compression stroke. This adds more fuel and pressure (compression) to the fuel charge. It then bounces back to the other side. Interrupting the bounce or reducing the distance will reduce the compression of the fuel charge and alter how compression is gained prior to the next opening of the intake valve. It may even put the peak of the compression charge directly under the carb in the plenum at some point which may cause it to stall or backfire.[url=https://classicgoldwings.com/forum/viewtopic.php?p=181395#p181395:oolhqmx0 said:chuck c » Thu Sep 29, 2016 4:58 am[/url]"olhqmx0]
Not that is really matters much either way, why is that a bad idea?
I'll pass that along![url=https://www.classicgoldwings.com/forum/viewtopic.php?p=181442#p181442:v5qp51ek said:dan filipi » Thu Sep 29, 2016 5:09 pm[/url]":v5qp51ek]
Compliments to the welder!
