    Mr. 8pack,
    This is Roadstar B asking about the center of balance of the engine.
    I put a small stick under the Roadstar engine from front to back on the line where the engine cases meet and the engine seems to be balanced at that point.

    I saw your bike in some internet photo and it was hanging up in a building.
    I was thinking that if a person look straight up from underneath they could see the
    cases where they come together and if they are in the center of the frame.
    Only if it is safe of course.


    Have you had time to look at that?

    Thanks for that answer about the oil tank height.
    I may not be using the transfer gear box and oil tank.
    I would be making my own oil tank.

    I used to live in Sausalito,Ca.
    I am now in Guerneville and have a tech question for you.
    I am building a custom bike and trying to determine the center of the road star engine when looking from the back.
    I was thinking that it would be great if the center is right where the main engine cases split. Am I far off?

    I know it's still early, but did you get permission to run the salt in 2014, or do we have to wait until 2015???

    Sounds good I'll enjoy watching the fun. Suggest studying Frankenstein's site (URL in his profile). He is a new model VMax nut these days, for good reason. However his vmax site retains his Warrior builds. Also, his threads and posts remain here, he was always very willing to accept and share advice and his results were generally excellent. Also suggest checking Nigel Patrick's old posts, see: Road Star Warrior Forum : Yamaha Star Warrior Forums - View Profile: PRWarrior because he didn't leave much 'up' on his company site at Patrick Racing Billet after the Prostar days.

    That will be fun. Lemme know when, I'll ride over. What frame and middle drive design are you planning?

    The boys at Patrick Racing discovered and shared the maximum rpm limitations of the engine design, there's links to conversations in Tomba's 'Popular Mods' post. Nigel Patrick owns all the recorded Warrior-specific top-speed records having dominated Prostar drags for so many years that the other manufacturers walked-away and ProStar collapsed from lack of competition (like CanAm and Porche lol). I mention this because your overall gear train including rear tire diameter and front drive pulley will need maximized modification for all high-end rpm. No worries since the bottom end isn't so important on the salt. That means its a very do-able project if the twins can be tied up real nice lol.
