  • Member-Intro: XS1100 Turbo

    Hi all,

    Through much effort by the Brass here (T.C.'s the Man - how appropriate!), I am finally able to log on and intorduce myself. my name is Warren & I live in Western Wisconsin. I have a 1978 XS11 that was my road race bike back in the 1980's. After grenading the motor (transmission actually) at Daytona International during the AMA 1984 Paul Revere 200, I transplanted a 1981 Midnight drivetrain into it, and fitted the beast with an ATP Turbo set-up. From then on, it was my street bike and Saturday Night At The Drags machine.

    Regretably I sold the bike back in 1990 while living in Minnesota; actually I traded it for a 1972 Pontiac LeMans with a 500ci Caddy motor which I sold for more than I was asking for the Turbo. The funds helped me finish College, and after graduating I moved to Arizona for a job. Well, the job went away, and I moved back to the Midwest last year, here in Wisconsin.

    While watching CraigsList just a few weeks ago (I always check the surrounding larger cities for cool stuff), there it was for sale, original as sold, 17 years later! it is now back in my garage, and ready for resurrection. My name was still on the title as previous owner! The gentleman who I traded it to was in his 60's when he got it (he drag raced it regularly while he was able to ride), and his son was now selling it due to health reasons; it has not been run since 2001.

    It is frighteningly fast, and has lots of chassis mods too. The engine is definitely up to the demands of the ATP Turbo, and it has not been apart since I initially built it back in the early 1980's. I was working as a bike mechanic at a Yamaha dealer when racing and building it, and learned lots of tricks through experience and working on most all of the 11's that came through the shop at the time.

    It was so exciting to get the beast back; I had always wished I had never sold it, and still can't believe I was able to return it to my stable. Over the years I have owned somewhere around 150 Yamaha's, but the 11TC has been my most memorable of them all. Thanks for such a great forum, and trust me that the next time the Turbo comes up for sale, it will be be at MY Estate auction!

    Cheers,
    The Yamanatic
    Sure it's gonna make some noise, there's GAS exploding in there!

    Cool.
    What are the odds of that happening?

    In the end you made a good profit.

    Welcome to the forum.

    Post a pic of your bike.

    Do you want it done right or do you want me to do it?

      Turbo XSive

      Well...
      I might have had the fastest XS on the forum.
      Guess it's time to put nitros back on like the PO had

      Would like to hear a few stories about racing it and a pic or two would be cool.

        Hey folks,

        Warren sounds like a great addition to the FAMILY!! He had contacted me thru the Website with regsitration problems, and he also included a photo which I'm putting in here. I'm sure he'll learn how to post photos later, so we can get lots of great closeups of his mods!! Also, he's a mechanic, so that's a great bonus to us all!

        I just hope he has the time to answer all of our upcoming questions about how to make these beasts behave to their most potential!

        This photo wasn't very high res, but you'll notice that it STILL has the driveshaft!

              Welcome aboard ... I myself sometimes wonder where my old 11 went and if it's still running or parted out. It's something else to get it back eh ...

              I would be interested in the frame mods, if any that you did to this bike.

                  Hi All,

                  Thank you all for the comments and encouragement! I will be taking pictures of the XS11Turbo this week; the one posted by T.C. is the photo from the CraigsList ad. The interim owner liked stickers a lot, and I try to peel at least one off every time I walk by in the garage (only 47 more to go!).

                  When I first started racing the XS11, it was esentially stock, and handling was precarious. This is sort of a relative term, because most all of the Unlimited Production Superbike class bikes of the day were precarious! To describe the offerings of the time in my own words, the Kawasaki Z1's were scary, Suzuki GS's dangerous, and the Honda CB's underpowered and resultantly predictable. The Yamaha XS was cumbersome and twitchy, but forgiving - I crashed it several times without falling down (an experience you must have to understand), and once WITH falling down; more about that later...

                  The main reason the choice was made to trade the headlight for a number plate on the 11 was was Daytona International Speedway. The Bowl is an omnious track, and my GP2 bike (an SR/TT hybrid Thumper) was simply not a good match there; I needed Lots Of POWER!!! To ride the banking effectively took a healthy 750 multi or greater; 550's were just not enough. The 11 was the ticket! The first time I raced the XS was at Daytona, and it was awesome; WOW! With an open header, velocity stacks, and the right jetting, a stock motor will propel my 175 pounds to about 142 mph given sufficient WFO time.

                  I actually learned to appreciate the shaft drive because the bike did not squat when cornering under power. You had to be a little careful when transitioning to keep on the line, as it had a tendency to try and stand up if you were too quick with the twistgrip. It would wag the front end as you powered out of a corner, but a stock RD400F steering damper and a Telefix fork brace made the gyration a sort of feedback indicator and was not unpredictable or intimidating. M45 Metzler PZ-2 compounds were very nice tires for the stock rims, as they would go away slowly and bite well even in a skid.

                  The frame on an XS is quite stout really, and it responded well to just firming the suspension. The shocks were a set of 12" Marzocchi remote reservoir's with a concoction of springs I cut up from salvage shocks; they were the stiffest springs I could find and were stacked with a tall collar to limit the travel. The forks were loaded with "Forking by Frank" progressive springs (the highest rate he had), an extra 1" spacer under each cap, Type "F" ATF, and balanced air-caps running about 8psi unloaded. The swingarm is fine for a stock motor, and was left alone.

                  On the High Banking, the suspension would bottom out on the bumps in NASCAR turn 2; you could barely hold your head off the tank from the centrifugical force. It felt more like climbing an endless hill than cornering a banked turn - like riding in a Bowl...
                  The bike actually worked very well and felt solid even when draging the pegs in the carousel. And best of all, it was competitive! Quite a lot has been done since the first excursion onto the track, but all in all it was formidable right from the start, and really gave a ride to remember.

                  Thanks again; I will be working on the pics, and how to get them posted.
                  Warren

                    Nascar, Daytona, GP2 bike, off the planet Yam, crashing without dropping the bike, nasty, some here for sure have too, Yam full noise with the turbo XS, reckon it would do 145 mph?
