First the problem and Question...
I recently Installed a stock 03' Katana exhaust on my 91' 600. Everything seems to be running well. It idles without issue and for the most part is very smooth. I know I have lost power but yesterday I went out to do some low speed skills in the course we made in the parking lot when I ran into an unexpected issue. When I come to the end of the setup there is a very tight circle followed by a slalom. I use the throttle to get the bike upright after a fast tight turn. This time I almost ate it right there in the turn because when I gave the bike a lot of throttle it accelerated but then sharply choked right after. It was identical to the feeling of running out of gas. I though it may have been a fluke however it happened 3 more times after. I checked gas, fuel petcock position throttle cable and air intake with no problems. This did not happen with the old exhaust on the bike. The only time this would happen with the old parts was when the bike was not yet warm. Any ideas?
My second question is if anyone knows how I can check if the gaskets at the header are leaking. I have obviously stuck my hand up there to see if air was leaking, but this is very crude and I can't leave my hand there for very long. The reason it comes into question is due to the exhaust swap. I took the route of shaping the exhaust at the oil pan to fit without putting in the other pan. When tightened down there is a 3-4mm gap between the collar and the manifold. Not all the way around but only the lower bolt area. I have a picture of what I am talking about and to show you where I am talking about. The picture is before the modification so that is not the size of the gap.
Clymer manual didn't say anything about it.
