More Predictable, but Still Stumbling... Predictably...
After only 50 miles on the 7.0 "upgrade", I now have a more predictable stumble at the 2,700 to 3,100 rpm range, most notably while in 2nd gear at or around 30 mph (48 kph for all you sui-side drivers out there). The fix is just to pull in the clutch lever and let out smoothly again and again and again and... Until you don't have to do 30 mph anymore.
BUT - there are certain conditions within which this stumbling occurs. Those conditions are:
1.) Heat (the internal fan is on)
2.) Trying to maintain at or near 30 mph.
3.) Usually occurs while decelerating to 30 mph from about 40 mph (in traffic) and then trying to maintain 30 mph again as the light turns green, the other cages start to move, etc...
It should be noted that I also have the full Remus exhaust system and race-flow air filters, which only amplify these conditions due to the increase in "performance".
On the lighter side, during other phases of operation, the on/off of the throttle is much more pleasant. To the point that I don't have to worry about the lash of acceleration when making a right-hander around my favorite corner. I like that!
So overall, it was an improvement, but there is still the stumbling. It's just, well, predictable!
