My name is Steve aka srsupertrap; I have been riding and wrenching motorcycles since the 1970s. I grew up in New Jersey and have lived in Colorado since 1999. I am a Medical Device Quality Engineer. My brother handed down his 70 Yamaha R5 350 to me at 17. I learned the necessity of reliability modifications earlier on especially with plug fouling. Like many of you, I was influenced by Kawasaki’s Z1.

I drove a pizza delivery truck part time in my junior year of high school. I met Big Al who managed a Pizzeria in Waldwick, NJ and owned a 75 Z1B. Big Al influenced me with his motorcycle camaraderie. Back then NJ required new riders to be escorted to the Department of Motor Vehicles (DMV ) road test by an endorsed motorcycle rider. Although Big Al & I lived in different counties, he agreed to meet me at the Lodi DMV for my road test. I arrived by myself early for the scheduled test. I was sweating bullets with five cars ahead of me before my road test but no escort. I heard Big Al’s Z-1 exiting Rt. 17 before I saw him. He bypassed the line of waiting cars and pulled up next to me, killed the engine and asked me if I was ready. I smiled relived, said yes. I think that is what brings us all together on forums today: passionate about bikes and willingness to help.

Although not too active, I am also a GS Resource Forum member dating back to 2007. I still own a modified GS1000E. After I purchased a highly modified but dead 1981 GPz550 in 2013, I joined The GPz550 Forum in 2014. I documented the GPz550 restoration on the GPz550 forum. Unfortunately my user name was changed from srsupertrap to n/a. Not sure what happened there. I also sell some stuff on Ebay too under the same name. I have been selling parts for Dr. Kieffer’s M.D.retired race mechanic. No vintage Kawi stuff though.

Looking forward to joining the KZ Rider conversation and adding where I can. My GPz550 picture circa two weeks attached.
Thanks,
Steve

What engine mods are on that 550? I can see you got some sweet flatslide carbs.

Thanks Mikaw for the welcome.

Those are Mikuni TM series TM27D1, e.g. 27mm. Mikuni sold them in mid 1980s just for KZ550/GPz550. I believe the kit came with new push/pull throttle & custom intake boots. They are simple to tune but from what I can tell most GPz550 owners & racers like Corey Clough do not run them. They are no parts anymore for these Flatslides so I am always looking for parts :)

PS: Anyone else running these Flatslides?

Currently rebuilding an 82 GPz550. I found a set of these carbs in decent condition, but the orings and bowl gaskets are leaky, so working on getting better seals first. Looks like I'm going to need to hand-cut the gasktets.

Have you determined if jets at least are available? What about vacuum nipples for syncing? Carb #2 has a vacuum port pressed in for the petcock, trying to decide if I want to drill that out for the others, or put a nipple into the rubber boot. (It seems like nipples for the former are easier to find, but drilling these carbs dos not seem like a great idea.)
