Suzuki GT750

 

I am thinking about getting a(n) Suzuki GT-750 for everyday use and
travelling. I have some questions:
(1) How often do I have to rebuild the engine?
 I had a small(80cc) two stroke and we had to rebuild it every other year,
 is that true for this bike?
(2) I have heard the breaks are "spongy" is there a workaround for this?
(3) How often do I have to replace the radiator?
(4) do I use more that one quart of oil per 250 miles?
(5) Is this a 12v or 6v electrical system?

Another issue that I forgot to mention is that the GT750 had three sets of
ignition points and low voltage coils instead of an electronic ignition
system
like modern bikes.

I was forever cleaning the points and resetting them. That was a routine
every
3000 miles or so. The bike would run crappy with dirty points.

I don't know if you can even get ignition points for a GT750 anymore. I was
using
2 sets of Beck Arnley replacement points to save money, but I had to buy the
one set that was different from Suzuki and they cost three times as much.

The weak ignition coils only put out about 12,000 volts and the spark plugs
were
always carboning up, so I spent a lot of time cleaning spark plugs.

The magazine mavens came up with a fix for the coils, they found cheap K-Mart
coils put out 35,000 volts and that kept the spark plugs cleaner, but the
extra
current was rough on the ignition points.

I installed three solid state aftermarket devices that reduced current
through the points
so they wouldn't burn so badly. The device just used the points to signal a
silicon control
rectifier to fire the spark plugs.

I worked on a GT750 endurance racer with some guys who had a novel solution
to the
points problem. They installed a Chrysler multifire ignition unit an a rotor
from a Dodge slant
six. They ground three teeth off the rotor to reduce the number of sparks it
would trigger.

This ignition system supplied three sparks to each cylinder every revolution,
so it had to
supply 72000 sparks per minute. And it worked, at least for the few hours the
engine ran
before it seized from overheating.

It seemed that there was some lint plugging up the waterpump, which is
mounted horizontally
underneath the engine.

Can I adapt this to efi?  Is that an impossibility? John

Will a finger nail file do this?
