Oh Yea Bob
I've had two Sportstrs since they rubber-mounted them , that came about in 2004 .
The first was a 04 -1200cc , the power was great ! Rubber mount and Carb-ed . It did vibrate a little ...
So , in 2007 Harley put Fuel injection on . I've still got a 883 , 2007 model .
After having both : I've come to the conclusion that ... Harley built the 883 and balanced it perfectly
. Its really a good bike if you don't mind the 560 # . Then as an after thought ...
... They desided to up the piston size from 3" to 3.5" (883 to 1200) ... well they threw it a little out of balance when they did.
Also , the 1200cc I had
,
I was trying to keep up with a bunch of WILD-SAVAGES on the Blue Ridge Parkway one year and was having a hard time doing it . So , I was running 2nd and 3rd gear up and down through the RPM range to use power as an EQUEALIZER ... It kinda worked .
But running that bike like that made the front sprocket of the primary drive start working on the crankshaft splines that drove "said sprocket".
The end result was the splines disappearing
. I made it home ... but less than a week later "said splines" were completely gone and I brought it home on a trailer .
So , I built a weld shield around the crank and sat down beside the Crankshaft with a welder and a Dremel tool . Apparently the factory did not have any taper to them to tighten up on ...
... So , the splines I built did have a tapper (lightly) and I used sandpaper and a drill to make matching taper in the sprocket . I rode it around almost a year after rebuilding the crank splines and it never came loose again , how could it ... this time it was two mating tapers tightened onto each other !
The most interesting thing I found was the fact that the CrankShaft was made out of Case Hardened Dough-Ball-Steel ...
... 1,25 " Dough-ball steel ... I couldn't hardly beleive anybody would put 1200cc power on something so small and punney !
It seems to work just fine for the 3" (883) piston regular gas motor but that isn't near enough for the power the 3.5" (1200) piston High-test gas
motor.
So in some ways Harley has got better
. But still not as good as a Single Cylinder 650cc I know of !
