Re: Schwinn Jaguar springer
Got my 1" springer from Ebay seller cruisinthelowlife. My mistake, will save it for another build instead of adapting. The Jag downtube is 1 1/8". ChoppersUS sells the larger springer and matching headsets, as well as adapting shims for the 1" to 1 1/8".
Don't think merely swapping stems would work, but I could be mistaken,,,,,again.
Which greenline did you buy?? Been looking at them myself and wondering about how well the engine would mount up. No experience with Greenlines. Have you?
