Here's the latest stat. At this point the 650 DP has a 68/78 jet combo, and went with an 8.5 PV. Now, nailing it from a slow rolling start will break the tires loose. :smokin:
BTW, can't tell you how many different formulas for a PV are out there. Makes it tough for us rookies...
Now, I 've got to decide whether to replace the primary throttle plates that were pre-drilled. It idles no lower than 850 rpms, and that's with the stop screws completely out (secondary as well). If I set the transfer slot exposure to .040 (or pretty much where the slot looks like a square below the plates) on the primaries, then I get 850. If I do the same to the secondary slot, I get 1050 rpms. Does it matter that they are not all equal? So anyway, if I didn't have the holes in the blades, I could get the idle down lower.
And a nuther thing, why not remove that secondary stop screw and insert it from the top of the baseplate so you can get to it?
So at what point do I quit playing with it? It's great as it is, but I still haven't messed with various timing curves, dual plane, etc. Don't want to leave anything on the table, ya know...
Wanted to add one thing... After checking the plugs today, it indicates I'm still a little lean (or too hot a plug). I'm to the white side of the spectrum with Autolite 26.
