I've looked at the available "chopper kits" for the Savage, and they cost more than I paid for my old '87 to start with. That is just too much money to me. So I continue seeking alternatives.
Then I recalled the name of the old shop that used to do forks for chopper guys clear back in the 1970s. "Forking by Frank" or just "Frank's" as most called it. And sure enough they are still around and have a web page:
http://www.frankmain.qpg.com/So... since there is no online info, other than contacting them directly, here is what I found out with a phone call:
They will do Savage forks, and even have them in stock. They no longer do really long stretched fork tubes due to issues with the strength of thin walled fork tubes. In fact, they will usually only do 2 inches over on most heavy bikes, but since the Savage is so lightweight, they will go up to 4 inches over stock.
Good news: the price is a very reasonable $215 for a pair of 4" over tubes, which includes everything needed to use your old parts. (IOW a spring spacer so you can use your original springs). But of course an extended brake line that isn't included is needed. Luckily, someone has already put an over length stainless steel brake line on my old 1987.
Bad news: I've done some calculations, and the 4 inches I'd like to add takes the trail geometry out a little farther than what is considered optimal. I've already bought a rear tire that is about one inch taller than stock. It will raise the rear axle by about 1/2 inch. But it would be best to raise the rear another 1-1/2" to get the trail back in line, and also I wouldn't mind having the ground clearance anyways.
So far, about the only option I've found for longer (and hopefully longer travel) rear shocks, is expensive Progressive brand shocks. If anyone here could show me where to get a more reasonably priced pair of tall shocks to fit the Savage; or even some air adjustable shocks I would be eternally grateful (ok, maybe not eternally, but I'd at least say thanks)!
Update: I've found where new 12-1/2 inch Showa shocks, like some of the old British and Japanese bikes used, are available. MUCH cheaper than Progressive. The seller says the shocks are suitable for "heavyweight" bikes and they look like a fit, but a little more skinny than the stock or Progressive springs. Also, I don' know what size mounting hole through the shock's bushing is needed. Can anyone tell me what size dia. the shock bolts (studs) are on the Savage?
