i have a 1986 GSX-R 750, and i'm going to put a ducati biposto tail section on. i know it's been done before, but i haven't been able to find how it was mounted. i have the full subframe for the ducati tail section.

Also, in the space under the gas tank, i would like to mount a battery instead of the stock location. anyone know of a battery that would fit in this space, preferably a sealed battery similar to an optima?

also, what sizes of screws do i need to replace all of the screws in the carbs with socket head cap screws?

i appreciate the help!

Looks like there was a kickass company, but can't find them now. Do they still exist???

Read these old threads.

well crappy... i already bought a ducati tail section...

Well...if you have someone that can weld for you or if you can do it yourself I would just chop off your current subframe and weld on tabs to attach the duc subframe to then. It bolts on, right?

i have someone that can do that, yes. but then i NEED the battery to be remounted... any ideas on that? last post for tonight, gotta work in the morning u know...

na....but if you search on here you'll find some posts on it and other guys on here have relocated them.

If you want to see a cool sv....check what this guy did to this one. He put an MV Augusta tail on it. See how he had the tabs welded onto the frame to mount the MV subframe....

Check out the size of the battery on the Honda CBR1000RR (2008? or 09). It's tiny, about 4" tall, 3" thick and 3.5 inches long. Has more cold cranking amps than the specified battery for GSXRs. It's sealed, can be installed laying on its side and will fit under ur tank easily. I think it's a YFZ7 or something like that. If you know your screw size, do a google for McMaster-Carr. They are an industrial supply, ship to anywhere and will have anything you want in stock. They are about the best around for any type of hardware.

The cbr batteries are a good idea.

The cap bolts are M5x1.25...I think the ones I used are about 12mm in length. I replaced all the screws with cap screws...even the ones holding them together on the rack. They were all the same size. Be sure to get small lock washers to go with them. McMaster-Carr is a good source, but I get mine from the local Fastenal store. They are also online.
