    I think the tire will spin on the rim at 6 or even 12, but i'll give it a try.
    If you like the Rat look, I'm sure that we could get out a torch and welder and really pull off some pounds it you want to have some fun.

    If you want a few pictures let me know and I will post.
    Thanks Lecroy go ahead and post a few, may give me a few ideas.
    Thanks Jake

        Jake,

        No problem. I added a few more pictures to my site that show how the starter was changed. Just go the the bottom.



        Saves about 4 pounds total. But the charging system also adds a load and with magnet is a rotational weight so you will gain a lot more than the 4 pounds. I would try and find a junked one if you can and maybe sell your good parts to help cover your racing costs. Just let me know if you have any questions.



        I tuned up my old GS the other day and drove it today. It's running good so I may take it to the local track this Friday to see what kind of times I can get. Seems like when it was running the mid 7's in the 1/8, it was running high 11's in the 1/4. It's been about 14 years from the last time I raced it. I put a new transmission in it when I rebuilt it so it should hold up just fine. I'm thinking I would need to spray in order to catch you.

          Come summer I'd like to remove the magnets and keep the onboard starter sence I'm already running a total loss system now.

          I bet that old gal will come back to life after a few runs. If it's like mine the more you run it the better it gets.

          Good Luck

            Well Jake, I took the old girl down to the track today. I had forgot how much fun it was to drive.

            Fastest 1/4 114.5 MPH
            Quickest 1/4 11.885

            Fastest 1/8 94.34 MPH
            Quickest 1/8 7.565

            The 1/8 MPH was all within 1 MPH. The 1/4 runs fell around 12.0. I tried keeping it in third but that really blew the top end (108MPH). My reaction times on it were poor at best. My best was a .593 (0.093) which is nothing to write home about. That skinny tire was all over the place. I got it to hook once and cut a 0.430 light with the tire a few feet in the air. That's when I got the 11.88.

            I was the slowest bike there I think out of a pack of 20 or so, but it got a lot of compliments for being so old and in such nice condition. I don't think they pay out anything for that.

              As long as you had some fun Lecroy that's all that matter. A little nitrous might just wake up them dudes and tell them you mean business.

              Tonight I found out my clutch did'nt like that wide slick. It started to slip in 2 and 3 gear, just had to back out of the throttle and let it hookup again. I guess it was about time it wore out. Best time was a few 7.10's and that was it. Best part of the night was when I was doing a burnout and I let the bike roll a few feet and that slick grab some traction and the front end of the bike came up fast and hard, so fast my left hand came off the handle bars and I was doing a one handed wheelie right towards the water pit guy, scared the *@%^$*@%^$*@%^$*@%^$ out of him and I thought I was a goner too. Can't wait to get the bars on too to prevent that from happening again.

              Best part the slick worked out great and it's a strange feeling making turns with that wide tire. Feels like the bike won't fall over and you really have to force it to make those turns, kinda fun.

              Ordered new plates and springs so by next week I should be good to go. Will see if I can reach 6.75 or better next time.

              Take Care

                lecroy, check your GSR inbox buddy. There has been a reply to your PM in there since the 27th of last month that you have not picked up yet

                Maybe you want to turn on the feature that gives you a message when you get a PM. I like that, that way they don't sit for weeks unreceived.

                  I took my starter to a machine ship and they put it on a lathe and cut the magnets off for me. I was agraid to remove the bottom part of the magnet assembly when I saw part of the threads for the starter are in there. I guess lecroy is proof that it works. I run 8.5 psi in my slick. A look at the tire after the run shows that to be the most even wear. I was 225 last year. And on the subject of riding with the slick. I ride mine like a 3 wheeler. counter steering will get you killed. if you want to turn right. shift your weight to the right, lean the bike to the left, and pull back on the right bar. When you lean to the left the tire is up on the left edge and will push the bike to the right. pup had a great article on riding a car tire bike online. A small tire is the same principle just not as drastic. Here is the url. http://www.stripbike.com/chassis1123.html

                    Better the clutch plates wear than other things!! Real good you didn't kill the starter guy!!

                    It was a LOT of fun. Thinking to go back on Sunday with a few friends. Not sure if I'm going to run or not. Maybe just shoot some video.

                      Thanks Ryan for the link

                      So to turn left I put more pressure on my right footpeg and vise-versa. The more pressure on the peg the faster it will turn or go in the other direction. And you do the same thing when the bike is on the bars to keep it going straight. I learn something new everyday around here....Thanks

                      I guess I won't be doing anymore SuperBike leans.
