I've been looking everywhere and the cheapest option I can find is $400-700. It seems the 4 speed option is only 150-300. Any idea on cheaper options for the 5speed. Would the Ultima 5speed kicker work?
Save yer Money.. Expensive PITA
and, those cheap 4-speed Kicker "kits" are Crap also.. Slightly better than the Aftermarket kicker kits for Ironheads...
Best way to get a Kicker ... is to get a Bike that was engineered for one.
It would work IF you change the trapdoor, got all the parts for a ball and ramp clutch release, and changed the clutch cable to a newer style.
The 5 speed kickers that don't include a main-shaft are total junk...and most of the ones that do are only slightly better junk...baker is the only one that will actually stand up to any real usage.
Any 5sp kit that has a mainshaft extension is wasting your money, put a lot of those on for guys back in the late 80's & early 90's and none ever lasted. More than a few snapped the end off the mainshaft.
As Tom said Baker is the only serious one out but she ain't cheap.
