    Bimota SB6

    I thought up a few names for this thread, but once I loaded this thing onto the trailer, none of them did the bike justice. So, I present to you, my Bimota SB6.
    It's tiny, and perfectly formed. And has 1100cc worth of Suzuki grunt buried between those epic frame rails.


    She's pretty shabby, but I can't stop looking at it.
    (note, while the tank, airbox and exhaust aren't fitted in that pic, I do have them. Seats and number plate holder, not so much. Headlights are on their way from Japan.)

    "Where can we get hold of a Vincent Black Shadow?" "Whats that?" "A fantastic bike," I said. "The new model is something like two thousand cubic inches, developing two hundred brake-horsepower at four thousand revolutions per minute on a magnesium frame with two styrofoam seats and a total curb weight of exactly two hundred pounds."

    I gotta ask, how much did it cost you?

    I'm partial to the SB8 myself, but still, wouldn't kick that one out of the garage!

    The plan is to have it sorted and on the road for less than the Katana & leftover spares sold for.... cosmetically she's a bit scruffy, really needs a full repaint and a couple of fiberglass repairs.

    Bimota SB6

    Epic!
    These, the V Due and Ducati 916 were my favourite bikes as a kid.
    Oh and the Britten v1000

    Looking forward to updates!

    may take a little while - in the meantime, here's a road test from 1996 - check out the RRP on it.

    I was at the creek in 96/97 when 1 of these turned up for a rideday, it made everything else pale into the background such was it styling.

    Thats awesome. The whole concept of what Bimota did was epic. Such a cool thing.

    Progress so far has consisted of ordering parts and moving it into the spot in the shed where I can work on it - in doing so I had to move the Mito, so briefly had them parked side by side. The Mito is much much taller, and feels to carry all it's weight up high when you lift it off the side stand, even though it's not even 130kg... Just seems odd that the Bim is 60kg heavier, but carries it all so low. Should be fun!

    Cheers. Still can't stop looking at it, and still can't believe I finally own a Bimota.

    Fucking miles off. Waiting on carb rebuild kits among other things. Also waiting for me to finish painting the dining room.

    I hope the painting the dining room is so you have a nice comfy place to work on it and show it off as the art piece it is.

    Awesome find!

    I've done a few small jobs on an SB8R at a mates shop. I love them because they're so different and the fact that the legends at Bimota said "fuck it" to being normal.

    I nearly bought a basketcase SB8R last year, but there were a few issues - NLA parts, EFI that no-one in Oz knows anything about, and it was unable to be complianced... The SB8R really is an exotic thing, but they're not particularly pretty with the stewie griffin forehead! Looking back now, I'm happy the kat didn't sell and I missed out on it, and this cropped up just when the Kat sold (stopping me from buying a 748SP).

    With any luck, I'll get the carbs off this weekend and get stuck into sorting them out now that I have my rebuild kit. I'll snap some more pics to illustrate some of the bonkers packaging in the thing.

    So, been struggling to find time here and there to work on it between getting dragged off on holidays and working on plastering and painting the front room (Fucking horsehair plaster, people who wallpaper over horsehair, and then paint over the wall paper!)... anyway, been hunting down bits and slowly rebuilding the carbs...

    So, went back to the guys I bought it off and made a template off the seat of another SB6 they had - the seats are basically unobtanium, so the plan is mould my own base for the main seat, and carve a buck for the bum stop, mould it in carbon and enlarge the storage space while I'm at it.


    So, to get to the carbs, it's off with the seat unit...


    and out with the carbs.... a few pics of the sights along the way - including the main reason FCRs are a bear to fit - you have to cut big holes in that crossmember for the float chambers.


    Note the clearance pocket in the upper shock mount:


    Oh, looky here - the oil filler. lol.


    Guess Marconi really wanted to wrap the beams tight around the motor...


    The original vacuum only fuel tap is another piece of unobtanium, and has been replaced with this piece of shit. Dunno how it fed the 1100, but it's got two, tiny 3mm holes inside it as part of the "turn to stop flow" arrangement... Bolt spacing is same as SRAD/SV650, but that's a whole nother story. Fuel level sensor is also missing, but the OEM ones never worked very well - have a plan for a replacement though.


    Onto the carbs - stripping in progress.


    So, the 90's "Slingshot" GSXRs had Mikuni BS-SS series carbs - BS40SS for full fat 1100s (US got 36 i think? DR650 also got BS40SS fwiw), BS38SS for the 7fiddy. They all have these fragile fucking brass tubes down one side of the carb - 3 curved to clear the linkage, 1 straight on the outboard pot. Of course, i stupidly managed to fuck the outboard one while trying to get the airbox on to keep the water out on the trip home. Then, while removing the throttle butterflies and shafts, I fucked another one. Oh, and one of the carb caps is cracks and fucked.... and to the rescue comes the 750 carbs I had left over from the 750WP I briefly had... except the caps are different - the 750 caps have the internal stopper ~2mm deeper, so I guess I'll be ordering an OEM 1100 one to make sure all slides open fully. So I stripped the 750 carbs, discovering they had a Dynojet kit in them (Dynojet bits are for sale if anyone wants them), and have started butchering them.... Have since got all of the casting off that brass tube, going to liberate a spare curved one, and the straight one too.


    Using a Litek kit to replace bodgery like this:


    Also took the one piece fairing off - I'll do it a better way next time!


    Hoover hose is the factory cold air feed to the airbox - not sure I'll bother refitting it.

    Some of the tight packaging (Headlights not fitted - from a Cagiva Elefant of all things, as is the tail light - later used by the1st gen Ducati Monster) - 2 small batteries under the gauges, overflow bottle wedged between the batteries, gauges and the headlights... and an adjustable steering damper, that you can't actually adjust without pulling the fairing off...


    There's all sorts of fun to dig through with loose fasteners, disconnected wiring.... this may take a while!

    Had some time to chip away at some smaller jobs on saturday - connecting up the ignition switch was one of them... fuck, what a ballache!

    Needed to move a coil to get enough space to connect the ignition switch connecter up in the steering head - well, fuck, that turned into a major effort - the spacers for the coils are loose, so you have to hold them in place while slotting the bolt in - and then not drop anything while getting the nut on the bottom. Had to pull the coil back out more than once to pick up a spacer or nut dropped and hiding inside the headstock areas...

    Pulled out a mullered helicoil on the seat unit mounts - they're a 3 diameter helicoil from factory, so wound 2 1.5D coils in to replicate. Luckily they'd only damaged the first turn of the insert, cleaned up perfectly when the tap went through.

    Removed the hoover hose and the rubber heat trap that kills the alternators on these while I was there. Had a bit of a shitty moment though, as I sprung the lower seat unit mount areas out to get it off the frame - heard a quite loud "Keeerack!". Inspection showed this:

    It appears when SB6s went from Mk1 to Mk2, the "reinforced seat unit" was a mess of chopped strand plastered inside the seat area after the beautifully laid up glass (most of it) and carbon (cosmetic for the exposed carbon in the "Raspberry Ripple" paint jobs) cloth was already cured.... anyway, looks like I'll be grinding that out and replacing it with some divinycell foam core and some carbon uni and cloth. There's the start of a similar delamination on the other side too. Not looking forward to the mess/itchyness of this job.

    Here's a pic showing the transition from the main layup to the reinforcing - have a suspicion the M in paint pen was to indicate that the job had been done.

    Aiming to get the carbs finished this week (just need to install the brass tubes and finish screwing it all back together), and get as many of the coolant hoses sorted as I can.

    Speaking of which... the lower clamps on the little connector hoses between the cylinders are completely inaccessible. Have to remove the lower steel tubes to do it. Sigh. (You can also see the rubber mat I removed here)
