    Look at the excellent photos and descriptions from Jason (Jason Abbott) and Ralf (Signit98) to see you how to do the job. Links to those sites are in this thread. If you look at those and are still nervous you might want to get some help. If you have some mechanical ability and look at those sites you will probably feel like you can do it. I have not done it yet either. It sounds like the cam chain tensioners are the bigger challenge as long as you mark everything first and secure anything that can be dropped.

    motorcyclemark,

    What you read on the powerfrkusa site are the findings and words of someone within that organisation based on any dyno testing they have done.

    There is a difference in the cam timing between the GS/R and the RS/RT/S engines and the GS/R engines have a lower torque peak so that the amount of rpm change is less and the S/RS/RT engines have a higher torque peak and the cam timing change lowers the torque peak more rpms.

    I hope this helps you understand the difference.

    I developed these sprockets in 2000 and have sold over 200 sets to date.

    Well, I meant it in that my opinion of the sprockets are 100% impartial, but yeah, we're all friends there. ;)

    Lennie, I have a feeling you may be selling more than just a couple hundred sets of these. I couldn't imagine riding a boxer without them.

    I have always yearned for a real first gear on my '07 GS. Will the Lennie sprockets help here? Anybody got a better low gear alternative that is not a GSA...I've already got one ('06) of those.

    Thanks!

    under identical conditions, will these sprockets change fuel economy, if so, what changes should we see?

    Thanks

    It's time for the post R&D pricing to drop. I'd pay under $100 for these, but not $225.

    Hunsolo,

    I have not had personal experience with the GS for 1st gear low end off road. Maybe someone here can speak from experience.

    I'd like to see a link for the installation instructions.

    would you believe it as fact if just one person said they got 40000km on a tire? I know that no one else disputed it but...

    Gas mileage will stay the same or better (if you don't change your riding style). I find that I rarely shift past 5000rpm simply because the sweet spot is now from 2500 to 4500 (lots of torque in that range). If anything, your fuel mileage may increase.

    Loaded up with bags coming back from Laguna Seca I got over 40mpg while @ over 70mph.

    Happy now?

    Lennie,

    So are you ready to sell more than 20/year? If you drop the price to under $100, you'll see them flying out of the shop...

    on a $18000 bike. Tires cost a lot more than $100. A service at the dealer costs a lot more.

    For me, the inhibitions are:

    1. Does it really work?
    2. Will it decrease the longevity of the bike?
    3. How hard is it to install?

    1. Does it really work?
    Yup!

    2. Will it decrease the longevity of the bike?
    I really doubt it, how long will you keep that $18K bike?

    3. How hard is it to install?
    Not too bad if you are mechanically inclines and have the correct tools.
    Be methodic.

    Tires are a must, modified cam sprocket is a luxury.
    I agree with your 3 points, but I also factor in how much it would cost to modify. I don't mind spending the money, I just don't want to get gouged just because it's a BMW. Some don't have the means to modify it and don't mind spending the money which is their choice. Being a machinist for 30+ years I know what it costs and not willing to spend that much which is my choice. Don't get me wrong I think it's a good idea, just a bit high on the price. In the end the only person who has to be satisfied with it is you, and what anyone else thinks doesn't matter one bit.:freaky
    I wouldn't even mind if they were in the $125-$150/ range for a pair, because new from BMW they are under $60 each.

    ...rough crowd here Lennie, I shoulda warned ya...:lol3

    I'm sure Len will be taking all this consensus in with a fair mind.
    That said, he did take the time to develop, test, and manufacture the sprockets (and a few other well sorted add-ons), and he is in Australia.
    I"m sure the price has little to do with the bike brand.

    I've had guys who say they work in machine shops and tell me they could make my barbacks for 1/3rd of what I charge for them, but that's like saying one could make a clay pot dirt cheap (pun) if they had a throwing wheel and kiln.

    I won't make a prediction, but I bet he'll be more than glad to do a group buy if there is true interest.

    Cheers :norton

    I'm one of the machine shop guys, and nope I ain't gonna bust on him
    over the price. I know how it is, folks coming in thinking your
    time is worth nothing.

    A little cut on a group buy might put me off the fence
    though :deal

    I'm not "busting" on anyone. I'm just saying I'm not interested at the current price.


    Lennie, if you want to keep the price as is, for any reason, I'm cool with it. Whether you're still recovering R&D, or if you're just trying to limit the quantity because you have better things to do, or if it really does cost you that much to produce the sprockets, or if that's just your preference - all are good and valid reasons for your current pricing.


    To the others who apparently feel Lennie needs a big brother to stick up for him, lighten up. What's the problem with stating the obvious in a open and respectful way?
