    Also a Conventional one. Dmaster has bought some to use on his BMWraceSaberg project.
    I think they were only used 1 year '96 if i'm right. The ones I have seen so far all had damaged chrome which the DRZ forks don't have that often. They have more travel than the DRZ forks and already have the axle clamps higher on the bottom tubes. For a travel bike I would use the DRZ fork.

    I have that one as well, also an adjustable KYB and a SM one that's a whole lot prettier, and that's been whipped into shape nicely.

    Personally I like to adjust my compression and rebound as well as my travel to the individual ride. As to the preload pressure, well a lot of that depends on the quality of the fork, but my performance has always been within acceptable limits. :lol3

    Just to confirm this: You're about to start making custom triples for the airheads, and those triples will be made to suit into the preferred adjustable conventional type DRZ forks? Tempted. :)

    Ras is right we already made the drawings. They will be gul wing shaped to use all the available travel trying to keep the front end as low as possible without shortening the fork.
    They wil also have holes in them to mount a MX type steering damper. The stem will be using the BMW size bearings and adjustment system.
    The handle bar mount will be KTM style with two positions to choose from.
    All the holes to mount a stock G/S or GS headlight are already in the triples including the holes for the fender.

    We still have no details about what they will cost or when they will be available.(I hope asap)

    A few months ago I mounted a Silent Hektik 370 Watt alternator with LiMa controller and ignition.
    The bike runs great and I have there ignition on a few of my other bikes too.
    Because I use my R80ST for a lot of low speed trials riding or single tracks I wanted an alternator which would charge more on lower revs than the stock system. (Although I never had a problem with my stock charging systems on my bikes except for a broken rotor. Which after they had been replaced with a re-wound one never failed again.
    Because I have seen to many burned out enduralast systems I thought I would give the silent hektik a chance.

    After riding the bike a few months I really liked the system. The ignition worked great and my volt meter showed 14.1 volts from 1500 RPM. But when the bike was getting really hot it would stall from time to time. At first I didn't worry about it.
    When I took the bike for a full day off road riding for the first time with this system the weather was warmer than the weeks before. When we were riding trough a forest on MTB trails the bike started to make shooting sounds and stalled completely.
    After letting the bike cool down for a few minutes it would start again.
    This alternator is getting SO HOT that the ignition pick-up mounted on the alternator stops working.:hmmmmm
    This is something Silent hektik warns about in their manual.... I didn't expect it to happen on a day with a 20 degrees C.

    So now I took the alternator off again and mounted the stock one with my old re-wound rotor. Problem solved....

    [​IMG]
    I still use the silent hektik ignition with the pick-up on the stock alternator which works fine just like my other bikes.
    Maybe this information will help someone who was thinking about using that charging system and likes to use their bike in hot conditions like I do. Or does someone know a solution for this?
    Opening the front cover isn't an option on my bike because my engine will be full of sand within a few hours:rofl

    On the triples, will they use the same offset as Suzuki or BMW? 22mm or 36mm??

    What fails on the Enduralast system. Are you talking about their alternator or ignition ? I have their alternator with about 50000km on it. so far no probs

    Likewise. That thing has been about as maintenance-free as possible. I forget I even have it until these threads remind me.

    The regulators failed on a few bikes I know of. They caught fire....
    Thats why some shops over here don't sell them any more.

    But what you and AW are saying sounds great and I hope for you guys they will last a lifetime.
