Carl's new Build

[Carlriddle]

Thinking on upper shock mount??  More brace??

[Lance-W]

I think the vertical load is ok but you need to do something to keep it from twisting the tube that you are putting the load into.....  See the crude sketch below

[Lance-W]

Like maybe where I drew the blue line?  Hard to tell without standing there and seeing it in 3D

[Carlriddle]

Lance that would work, also down to outside tube.  I knew it need something else, and up to roof might make motor a perm mount.  I think I'll go stare a bit at see what the voices say.

Carl,  Does both the spring force and shock force transfer through that mount?

If the spring and shock forces are in the same plane you should be good to go with the double sheer mount, but if it is out of plane, as Lance is elluding to, then you may want to add some reinforcement.  Perhaps just some gusseting at the mount intersections would be sufficient?

2 cents

[Carlriddle]

I'm either going to run a tube straight forward or back to outside frame rail.  I looked at both ways but will wait for a few other items to decide which one.   Will build airbox this week and it might be too close to rad since I had to lift engine to get exhaust to run under.  Need some oval exhaust tube to go thru frame. Hummmm to Internet I go.

While studing shock mount, I had to twist lower mount to stay within shock heim.  Cycled rear susp, all is good.  Made a few tabs to mount middle seat, just nothing photo worthy.

Then UPS stopped by, woohoo my new wing trunk.  But It was too big, so I had to cut it down and will have a couple new bends placed before having it welded.  Pics then.  Ds was pretty sure I could get 30 beers, 1000' of tow rope, a shovel, and a floor jack.  now I'm down to 100' strap and a 18pk, so BYOB.    Also got plates for new airbox, and have sump welded on my old alum tank.

[Carlriddle]

Made new airbox.  Filter from mid-70's datson 240.  But I've lost one of my stacks.    Also moved the rad back and down a bit.  Much happier with this location.

Looks good!

Working out my final gearing.  And since anything smaller than the 15T zx12 sprocket is like finding Jimmy Hoffa, I've found a machine shop to cut some up.  The zx gearing internally is taller than some of the other sport bikes, I'm thinking a 12T front will get me close.  Chart bottom right compares it to busa.  Thought?

[fabr]

Trouble with busa tranny's is they are too close ratio from 2nd up with a big step from 1 to 2. Further ,first is wayyyyy too fricken high to start with. Of course ,my buggy is 1800# approx without passengers. Lighter buggies may not need a lower first for taking off easily on slopes. 5th and 6th are way,way,way too low also. Maintaining any decent road speed should not require 8K + rpm. No need but unless willing to spend$$$$ we are stuck with it.

looking good

And the zx is 10% higher in 1st.  Going to try the 12T and then have a 13T made too after I see how it does.  Probably some spares as I'm concerned with how durable they'll be.  Be happy with a yr+. 
Next option will be a new rear and the common 14-15T fr. 

Thanks DS.

i wouldn't be surprised if you get 2 years out of the 12t but that's still a tight bend so as long as your chain is long with that big rear sprocket you should be ok on chain heat.  the rpm would be nice but for the money i would be going fabbers direction in the future.  looking good carl
