Title: '76 175 Jackpiner Shocks
Post by: davelar on November 21, 2011, 09:28:14 PM
I have restored my '76 175 Jackpiner. I am the original owner of the bike.  Years ago I enjoyed racing and trail riding the bike.  Now I intend to use the bike in casual competition.  I wanted to put new shocks on the bike and would be interested in what shocks people are using on similar bikes.  The shocks must be AHRMA legal.  Any thoughts or opinions would be welcome.

I have a 1974 Jackpiner  and the rear shocks are Shock Performace and they work great, but they are not cheap.

Does anyone have any experience with the vintage Koni's. I've been thinking about buying a set of rebuilds from rdhaag. Does anyone know how they perform or do they just look cool?  Tom

Performance options such as tires/shocks have factors such as budget and use to consider.  From a restoration perspective a shock such as Hagon can be used for a Girling or Koni period look with/w-out stainless shrouds for around $250.  Progressive/NJB offer a product that is also period looking and a little more suited for general trail riding, cross-country, and light motocross for about the same price.  The next stage of dual rate spring gas charged shocks (i.e Works Performance $450-$500) all effectively double the investment but offer performance for the serious active racer.  For the unlimited budget and the wow factor Ohlins at around $650. complete the list.  

I'd say Progressive if just once/twice a year and you are not riding at an elevated level.

Thanks Dale, nice rundown!  So Koni's for display only:). I have a set of progressives on a six day and have been happy them.  That's a beautiful collection of bikes you have. Later, Tom

Tom, hi,

the Koni's you are refering to are race quality,
they are built by Robert Haag
he was part of the start up of FMF in Cal. back in the 70's
Robert and his brother did much of the porting and engine work for FMF, you can find alot of early Elsinore cyls with the name HAAG stamped on them,
he also came to be a local hot shoe Pro Moto-crosser as well,

you can buy these Koni's with total confidence in their preformance and quality,

hope this helps,

PS: contact him and tell him i refered you from the POG,

regards,

Has any other low-budget racer like me run rebuilt 14.25" Curnutts with any success on pre-'75s? Simple and cheap to service, don't wear out, decent dampening and 1/4 the cost of Works?

Big Mac, I'm running Curnutts on my 74.5 250 HS and like them a lot.  I used to have the piggyback Zokes, but they were too harsh and beat me up on the trail (I'm a CC guy).  The Curnutts are just soft enough to keep the rear wheel on the ground and be easy on this ole' guy!

I've also got a pair of 16" Curnutts on my 390CR Husky for the same reason.  Originally bought Works Performance b/c I was doing MX at the time, but when I switched to CC they were too harsh.  The Curnutts were just the ticket for me.

Currently I'm looking for a pair of shocks for my 73 JP, race quality.  WPs and Ohlins are about impossible to get on eBay then rebuild (everybody wants them), can't afford to pop for new ones, so we'll just wait..........

Believe I've got a pair or two 14.25" Curnutts, 1 pair needing rebuild. Also a pair of 16". I've never been called on it, but believe the 14.25 inchers have a bit more travel then technically allowed for vintage AHRMA rules without putting in travel limiters. And the 13.5" versions are too squat in the arse for correct bike setup, IMHO. If someone has a desire around $100 or so give a call or text 503.888.2851

Jon, I'm interested in the 16 and a pair of 14.25; I'll call tonight around 9:30 eastern time, you'll probably be having your morning coffee on the left coast!

Mick, give a call anytime 8-8 pac time, it's my cell. Other interest in the 16" pair, so first chance you get, drop a line.

Other set I pulled out are 13-3/4" to centers with 4" shaft travel, by the way.
