    So whilst transiting from pub to pub down the Cowley road in Oxford I found this in a barbershop. Being quite a few beers in I decided to investigate and was sent to a nearby guitar shop where I was treated to a twenty minute soliloquy from the owner on the merits of the K series BMW, he did though take my number and promise to pass it to the owner. A week later and a phone call and I met up this morning with the owner and shook on £2200. I'm very happy with that. It whispered to me that it has always really wanted to be a mid 80's endurance replica.
    So, I figure the winter won't be much fun just sending off the Banshee parts to get the frame made so I'm going to do this instead and sell it in the spring leaving the Banshee motor and radiator in the spare bedroom for now.
    It is a 7/11, a very early 1985 750 frame and a 91 1127cc motor. I'm sure this period conversion will eventually be thought of as a kind of Triton of its day?? It does have a Spondon swing arm and an Ohlins shock, TL1000 front end.
    Plenty to do to make it black and gold...
    I had a ride out on it, the motor is strong and runs clean, very torquey. Front discs are warped which made me a little cross eyed and the steering is so steep with the TL front end you are trying to pull the thing back out of corners where the front end is falling in. Not a relaxing ride but ok for 100mph+ straight. I got loads of boring specs coming up as it comes apart... :hmmmmm

    I've been struggling a little with the concept of building something to sell rather than building it for me but the plan is to sell in the spring so rather than an outlandish Japanese Bōsōzoku or something in primer grey with sharks teeth I'm going for the slabside bodywork and black and gold which was the 1988 GSX-R1100J limited edition. Decals purchased and paint only has to be gloss black, simple.
    I measured up and have close to stock wheelbase 56", 1100 was 57.7 I did wonder if the Spondon arm had been lengthened but it would seem not.
    Weight is 420lb wet , the 750 was 410lb and the 1100 529lb. An extra 30-40Hp with the 1100 motor over the 750.
    The motor is prefixed V711 which is a 1991M, should have 40mm carbs but I only have 36mm, runs just fine though.
    The rake though is another matter. It comes in at 23.2 degrees, lethal.

    So if I drop the forks as far as I can in the lower triple

    IMG_2609.JPG

    I then get a more respectable 25.1 degrees and 3/4" reduction in trail, would have to make a new top triple though. The stock was originally 25.5 degrees but they soon sharpened it to 24.5 but lengthened the wheelbase an inch at the same time.

    IMG_2613.JPG

    So to overcome this....I already have an R6 front wheel and lower triple. Forks are 43mm and cheap on Ebay so back to a conventional fork and sell the TL1000 front end complete.

    Cool project. Thanks for sharing.
    How is the engine bolted at the bottom? Are those custom brackets? Hard to say.

    Increasing rake increases trail.

    I think they are factory, the reason this conversion was popular was the fact the 1100 motor goes straight in the 750 chassis. Most people at the time didn't change brakes or suspension though leading to an 'interesting' ride.

    Wrote that sober!! Going to pub in minute though :drinkI am in part doing this project to keep me out the pub (weekdays only!), it's only 50 yards away and I've got in to the habit of going for a couple after work..... The logic is that my Banshee project is mainly getting parts made and waiting whereas this I can really get stuck in to and work in to the night. I am really enjoying tearing this apart.

    Definitely time for a beer.... :beer

    IMG_2632.JPG

    Stuff ordered today. I know the exhaust that was on there is more practical and probably better suited but I've wanted a bike with one of these for about 30 years.

    oh ok. That is very convenient. I had a 750 at some point but didn't realize they were the same dimensions.
    The 750 had good power so the 1100 should pull like a mule.
    Love projects like this. Keep up the good work.
    Thanks.

    I believe this is what's known as 'artisanal metal craft in a modern café style'.

    Lock stops removed a'la 'acksaw and oil cooler mount screws used instead.

    Not the first time it's been fitted :fpalm A selection of holes, and not in a WLW style! This is the worst bits I've found so not too bad really, the bike has been looked after, moly on all the threads and everything greased. There was zero swarf on the drain plug magnet so the motor should be fine, I hope there'll be no more surprises.....

    Oil cooler removed and it's clear to see the frame and engine were painted in one lump, I heard that people do things like this :dunno

    IMG_2649.JPG

    What a beautiful arm :viking

    IMG_2650.JPG

    All ready for engine out tomorrow then get the frame off for vapour blasting.

    A tight fit indeed, no wonder the later frames had one removable side. The breather cover on top had to be removed along with the sump, pick up, and the oil filter got a screwdriver hammered through it. Messy but it's out :-)

    Not so great, number two pot has been running lean. A careful investigation required, I'll need to know why before it goes back in....

    hopefully is just the carb and/or simple valve adjustment.

    I zoomed in to see if the frame had the removable section before I got to where you said it didn't.
