    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

    Speedmoto VM30 Kit

    The stock CV carbs run horribly with K&N pods, the diaphragms in the OEM CV carbs need smooth laminar air flow into the carbs to get a good reliable vacuum signal. It works after some fidling around, and some people say they run fine...I don't believe them at all. I have had pods on a stock...

    GS400/500 Gr650 Hybrid engine

    Small update, I have decided on the way forward and have ordered the parts. I'll be using GS1000 con-rods on the GS400 crank, the challenge here is the difference in big-end size. GS400 GS1000 Stroke 60 64.8 Crank Pin 28 29...

    GS400/500 Gr650 Hybrid engine

    Forget about everything I said below, I did some more thinking and although it would be possible to modify the GS500 crankshaft, the real issue is the big-end plain bearings. Mixing roller and plain bearings is not a great idea because of the needed oil pressure towards the plain bearings. I...

    GS400/500 Gr650 Hybrid engine

    Small update regarding the hybrid engine, I went and picked up a bottom end for 25 euros, a steal! The seller had a lot of stuff so I got myself a whole bunch of seals, o-rings, and gaskets. Also I got a bin full of nuts, bolts, washers, 2 crankshafts including their balancer shafts and some...

    GS400/500 Gr650 Hybrid engine

    Update 2 I wanted to make the rear swingarm look a bit more aggressive, the GS500 rides amazing with an USD front fork and doesn't really need any bracing in the rear, so this is purely for looks. I started out by drawing the brace on a piece of paper, cut it out and stick it to a rectangle...

    GS400/500 Gr650 Hybrid engine

    Hi guys, I have studied the art of necromancy and bring this thread back from the dead! I am just going to continue like nothing happened...well...life happened. And life has put this project up in the attic in boxes for a looooooong time. Back in 2016, I had send out the crankshaft, custom CP...
