Today did a whole lot of measurements, close to 400, measuring the position of the exhaust and inlet valve against the crank shaft angle.
So will start entering all the data in a spread sheet, and do some graph magic…
Above you see the overlap measured at a 6 thou opening. It measures about 30 deg, where as normally its about 60 deg. So it looks like the exhaust can indeed be delayed quite a bit….
Lets wait for the comments from the CAM specialist and then decide how we are going to make adjustments 🙂
And if you are interested here is the spreadsheet with all the measurements and graphs :xxxxx
