Track day/fun bike build, 85 R80RT

I'm in the process of building a bike that will mostly be rode around town for fun and also a few track days a year. The bike is a 85 r80rt. So far the upgrades have been.

custom subframe/seat.
flipped bottom triple clamp on top
woodcraft clip-ons
Rearsets
forks rebuilt and 10wt oil
New cables everywhere
new oil everywhere and oil filter.
Bridgestone bt45 100/90/18 front, 120/90-18 rear

For now i'm going to keep the motor/exhaust/intake stock. What I am interested in is making it handle better. The upgrades I want to make are, not in any order.

Frame brace
fork springs (wilbers linear or racetech emulators and race tech springs)
wilbers rear shock.
Duel SS brake lines (individual Lines running from the lever to calipers)
ebc pads


I just got the new top clamp mounted and now looking for a new option for the instruments I looking into fitting a Scitsu tach and mounting indicator lights for the gen and oil.

I'm always open to suggestions on what i'm doing. Thanks for looking.

Has anybody mounted a scitsu tach to a electronic ignition? Also I'm having a hard time finding a place that carries idiot lights for the gen and oil lights. I know the gen lights is a 12volt 3 watt light not sure what the oil light is though.

For the lights, any little LED should work.

Get the right size front tire and the handling will be better. And go for a custom build shock thats longer than the stock one.

I do plan on the next set I get being a 90/90-18 front tire, The only problem (if you can call it a problem) is that I had to lower my front end about 1 inch because of the new triple clamp to mount properly. Right now I am running the stock front fork spring (.770 kg/mm) and the sag with me is 27%. I was thinking about setting a little preload to raise closer to stock height but I don't want to go less then the 27% I already have. My thinking is the 100/90-18 tire would raise the front just a tad.

As for the longer rear. It was thinking about a longer shock. Just did not know how it would affect the shaft.

If I ever run into corning angle problems I plan on raising the motor.

The 90/90 tire does handle better although you will go over the edge of the tire. But with the front as low as it is now you need to get some more height in the bike indeed.(specially iff your doing track days)
With the stock height front end there isn't enough cornering clearance imo.
For my mono's I needed to make a dent in the exhaust otherwise the shouck wouls be stuck in my exhaust. I will check what shock length is still safe for the shaft.

I was also thinking that if I raised the rear end a little it would also make the steering a little quicker. Not sure what the actual degree change would but.

Mean front view. Ya like the stands. When I was mounting my rear sets, I had the bike up on the center stand the whole time. The day came that it was time to take it on a test ride the center stand rested right on the shifter lever....simple delete made everything good. I also tried setting up the side stand and it also rested on the shifter.

As you can see the top clamp is simple and very precise. I did have to raise the forks up a bit to about .40 or so from the top of the clamp, which lowered the front just a tad.

Had to ground down a axle nut socket to fit the acorn nut hole. Did it on a bench grinder, Pretty happy how good it looked.

As I don't use turn signals I deleted all the excess in this part of the harness.
