Hey, I am 67 and still going. Yea I have a Bazazz with a auto mapper. So I don't have to take it to a Dyno guy. The injector is a 400cc and it is installed in the stock throttle body. I am installing a slipper clutch and a Factory Pro Shift Kit while it is apart. The 305 kit and cams are installed and waiting for a clutch holding too to install slipper clutch. I am running Sava race tires. I also have titanium motor mount bolts, caliper bolts, sprocket and disc bolts along with ceramic bearings back and front. Nobody makes a 415 sprocket kit so I decided to try these other things, trying to get the revolving weight down as much as the 415 kit would. Really close to same price. I was hoping to have it ready for a track day this weekend but all the stuff isn't here. Ari got his 250 to under 300 lbs I was told. Can't find the info on that, but feel mine will be around 300. Every 7 pounds is a horsepower. I didn't do the porting I wanted to, next time. Woodcraft is making me a a keyless ignition harness, I have removed stuff on the frame which was a pound or so. I want it done.
I also have a tick SV650 I race, won a championship with it a few years ago, it right at 318lbs 85 hp. I got a Kevlar tank and PM aluminum wheels that really help. On the CBR air box, I also am going to add some those UNI small round filters too. I race at 4200-5000 feet and need more air.
I will let you know the weight as soon as I get it all together. Oh yea, I run 110 race gas. Got to to beat all the other 300's. I am 155-160 lbs and am trying to get that down too.
