Background: I built a 70 GSX clone back in 1995. The setup I had worked great for many years. Had the engine out recently for some fixes and thought I would have the transmission gone through. I told them to leave the VB alone because it had a shift kit in it and loved the way it worked. I'm am looking for my invoice to tell you what all they did but in the end it was a lot. Pretty much an entire rebuild. Got everything back together and broke in and started testing and tuning things. Current issues: Issue #1 I did have a shudder from 1-2 under medium to heavy throttle but no issues under light load or under WOT. I did have the modulator screw turned in about 1.5 turns to the right for a firmer shift and later low throttle shift points. I backed that out and tested it some but haven't fully tested it to see if that issue is gone totally. Any thoughts on that? Issue #2 The shifts for 1-2 and 2-3 used to be at 4600-4800 at WOT. Now the 1-2 was 5200, and I let it go to 5200 but couldn't stand to let it go any higher to see where 2-3 happened. I had another governor so I swapped one in with heavier weights. The shifts for 1-2 were at 4400 but let it climb to 5200 and still no 2-3 shift I put a heavier spring on one side to see what that would do. The shifts for 1-2 are at 3500 but still no 2-3 shift. I saw mentioned a number of times in the forums the B & M governor calibration kit but seeing how it is shifting at such a low rpm for 1-2 with a weight and spring change already that perhaps I need to look elsewhere for the 2-3 WOT shift issue. Any thoughts on that?
