    Gs with 6inch wide rear wheel?

    I've got a 180 tyre on a 5.5 rim in gs550 frame with an oil cooled engine .  Even though the frame has had material removed around the chain and on sprocket carrier , to get the 520 chain to clear the tyre things are not straight .   I might go to a 5 inch rim and 160 tyre to get a straight chain run and decent life out of my chainset.  Maybe I need an offset front sprocket to bring things inboard a touch more ,  not sure there's even room for that , hope this info helps 

    Out of curiosity, what rear wheel are you using, and are you using the stock swingarm?

    Customgs,

    First, I am curious as to why you want to run a 6 inch wheel.  Is there any other purpose than "it looks cool"?  In the setup you want to run (600 engine in gs550 frame) an extra fat wheel and tire will hurt performance more than it would help.  The fat wheel and tire has a lot of inertia to overcome to get it to start spinning.  The stock 600 engine does not put out a lot of torque.  A larger, heavier bike with a large, high output engine would benefit from from the wide tire with it's greater traction. 

    That's my mechanical engineering thought process; if anyone else has real world experience that differs, please share.

    Whilst getting a 6" rim in may be nigh on impossible, even if you did the rubber on it will most likely give you even more issues inc the above!

    Not a lot in it, but try a 5.5" instead ;) 

    I will most likely do the 5.5 because it does look like less hassle. I am only running a 600 now, but future plan include a 1200 bandit motor as soon as I find one that's cheap enough. I will admit it would mainly be for looks, I couldn't see much difference in handling in a 5.5 vs 6 inch wheel. Running a slightly taller tire would cause a quicker tip in would it not?

    Which gs? 

    like most things, anything can be done, you'd have to get a swing arm to take the 6" rim then cut some of the frame away for chain run and use a spaced front sprocket .

    Can be and has been done.

    shaft drive frames (gs850/1000) with a chain drive motor put in, have more chain run room ;)

    I have an 81 gs550 with a teapot 600 motor. I would like to monoshock the bike and use a swingarm from an 06 gsxr1000 which have roughly the same swingarm pivot width. So instead of cutting some out, could you heat the frame and dent the frame for chain run clearance?  Or would that weaken the frame?

    I would think swapping the complete 650 would be the easiest.  But if you do decide to use the 550 bottom end and the 650 top end, use the 650 cams. When using the 650 cams you will need to switch the timing gears off the 550 cams to get it to work.

    I believe mac 4 Into 1 exhaust is all they sell anymore for the 550/650.  

    Also the CV carbs are more difficult to tune, but are tunable. I tuned my 550 with cv's and velocity stacks, and it ran rather well after playing with some different jet sizes.
