    Best Run so far, no bar

    Ran a few 6.44's in the 1/8 and a few 1.52 60 ft's too this past weekend. Was starting to carry the front wheel some too. I guess that's not too bad with struts and 16 psi in the 7" slick.

    Being the only 30 year old bike with a 20 year old Katana head it was sort of nice puttig 3 of those ZX14's on the trailer before I was sent home too

    Take a bow, brother.
    Great to see the old brutes put the new brutes in their place.

        Yeah, make's me think if the old GS had a fairing like the newer bikes and if I lost alittle weight since I'm around 250, I probably give them a real run for their money

        A 1.49 60 ft is my new goal now

          If you are running it without bars, put a set of shocks on it & you WILL bring the 60s down by a tenth fairly easy! Ray.

            I like a full body , it helps the MPH - but a side wind is the trade off.

            how low is your chassis? - advantage

            I ran around 11 Psi in my M/T 7"slick - but I had a wheelie bar.

            I'm building a no bar street style bike for next year -- DOT tire, single stage lock up 68"W/B I'm not used to this so I may have a few questions next year. I have a strut but if shox really help that drasticly I need one.

              It's just a stock GS frame with a 90's gsxr swingarm thats been extended around 4" so its about 65" long. Right now I got the rear about as low as it can go due to the swingarm touching the frame. Plus I'll need to fab up some shock mounts if I go that route. I bet my bike weighs more than 750 pounds with me on it ??

              Right now I like how it feels and can drop some more air pressure and see how see launches again without the bars. Or I can just bolt them back on quickly and not have to readjust anything. I run about 8 psi when the bars are on too.

              A slider clutch would be awesome but they cost an arm and a leg!

                I love my slider!me and my pro bike are 235/460= #695~#700

                but at 65" running a no-bar slick ?!?!? wow I admire you sir. carrying the wheel

                index racing is getting popular. Ther rules are a little binding like DOT tires and throwing a lever. 68" and 70" max - working head and tail light, suspension.

                10:50,9:50, 8:90.. I'm still not sure how I'm going to get it done.

                maybe a little nitrous and a really safe engine combo OR Tons of compression and loose me some weight. either way I got to get it lower -
                need some short 37mm tubes and sliders.

                and a rear shock -my strut is technically illegal I'm not sure how much they check. Tech is a snap at most of the places up here.

                  Yeah, you got to be careful coming out of the water box cause onetime I stood my bike straight up with just one hand and scared the hell out of the water box guy and me too

                  I've finally been able to make some clean runs the past two times out after fixing a air shifter problem, that darn PSI gage had a intermediate leak and I was chasing my tail replacing and testing everything else. You know Murphy, works fine at home but once at the track all heck breaks loose !!

                  After a few more outings and I get a good feel at launching I'll fill the NOS and see how she runs with a 25 shot ? That should crack the 5's in the 1/8.

                    hey jake what sprockets are you using?
                    front and rear?

                    are you using a lever clutch? what RPM are you launching at?

                    I'd like to get a good combination that works before I put my butt on the line.

                      With wheelie bars I run 14/46 gearing, but since I've took them off for the past few months I kept the 14 on the front and went with a 48 rear to help get it out of the hole.

                      The 14/48 combo seems to work for me and my weight around 250 suited up. I even removed the lockup and went with 3 oem springs and 3 HD ones cause I like a heavy clutch lever.

                      As for launch rpm I really don't know ?? no tach just a shift light set at 9800 but I'd guess around 4 or 5 grand. I go through the 1/8 traps in 4th gear with the shift lite on and thats with the M/T 7" slick. Most likely I'll add a 2nd shift light with different pills until I can find the best RPM launch.

                      If I can get a solid 1.50 60ft that should give a me a 6.39 time or better I hope ?? I know I can get more aggressives with the throttle and clutch. Been trying to get away from thumb racing this year if you know what I mean.

                        great no bar combo

                        Fantastic. That is really some excellent information. Thank you for sharing.

                        I have the single lock up and 3 red and 3 regular springs..

                        I have the sprockets 14-15 46/47/48/49

                        I'm 240 in suit and the bike is going ot be 450-ish . I have a 1150 front end (heavy) but I want a regular gs1000E fork/skinny 18"(light). she's raked and at 68" now. I have an old fangled 18" GSXR wheel that has been widened to 6" by welding material on the edges and cush drive welded solid too. never seen one til I bought it. I can use a 7" slick or a 180 DOT radial on it. Going to lower it as far as rules allow (2"). if it works I plan on fixing a lot of red wagons next year. young punnks think a "sissy bar" bike is too deadly aaccurate.. ha! just wait.

                        I'm amazed you went bigger in the rear after removing the bars. I thought you'd soften it up without the bars.

                        But if you are not spinning, not lifting, and getting good green R/T's I'm all ears.

                        LOL! thumb racing is my speciality! yeah I tune with air gap. top bulbing or bottom, I'll be out of my element wiith a clutch in my left grip instead of the front brake.


                        I have changed a couple things since this picture was taken.

                        here it is at 73" and I am going to lose the GPZ fairing. My seat is going to be right on the frame bars (no foam) you can't cut the frame rails to alter center of gravity , more rules to comply with.

                          I figure a bigger rear sprocket would help more getting the bike to move ?

                          With struts and a slick my tire pressure is the only adjustment I have with the frontend strapped down. Had it at 16 psi when I ran my best 60 and ET. I'll drop it another 4 psi and see how it runs next time out ?

                          With bars I had it set at 8 psi and got a few pic at launch and it almost looked like the rim was touching the ground when the slick was wrapped up.

                          Looks like next year going to be fun when I start using the nitrous again

                            Keep in mind Jake that the heavier the rider, the higher the tire pressure. Just because someone else uses a different pressure doesn't mean it will work for you. ESPECIALLY if they have a 120 jockey on it! Ray.

                              That's what I like about test and tune days Ray, lets me play with things and see what works best for my combo.

                              120 pound jockeys should be outlawed !!
