    1981 GSX1100 Katana Based Project

    The super light weight chain guard was supplied with a titanium allen bolt and aluminium spacer. The spacer is needed to off-set the guard position as the 520 rear sprocket is installed 8mm closer to the wheel than the stock carrier due to using a lighter sprocket carrier. Carbon guard hardware...

    The project Kat had a full length carbon chain guard fitted and although lightweight when compared to the OEM steel chain guard, there are lighter aftermarket guards out there in the wild. Caught this tidy used carbon guard, sooo light. Carbon guard MKII by Max Mutarn, on Flickr Carbon guard...

    I scored some used carbon parts on the weekend so a few more grams to be shed once they are installed. Also having a set of machined aluminium mirror mounts made to replace the current set that just look wrong as well as being heavier than they need to be. Pics of carbon parts and mirror mounts...

    1981 GSX1100 Katana Based Project

    The muffler that had been used for the build decided it didn't want to be on the Team and threw in the towel, the titanium inlet parted company with the can flange. I found a pretty decent used carbon and stainless muffler to replace the damaged titanium unit and installed it today. Sounds good...

    These Kats are 42 years old and still look good, parked up or going for a blat like on this perfect day. Kat Ride by Max Mutarn, on Flickr

    1981 GSX1100 Katana Based Project

    Update on the mirrors, the stems are cast aluminium and not forged aluminium so drilling or thinning down the stems may weaken them. For now the mirrors will stay as supplied and not be modified however, because they are wider than "Old School" Suzi Kat mirrors I can now see in the mirrors...

    1981 GSX1100 Katana Based Project

    The mirrors arrived today, 773 grams total for the pair. I was hoping they would be lighter having aluminium stems so this will take a bit of work to make them lighter. If I can get them down to 600 grams that will be just over 30% lighter than the OEM mirrors so that means taking 87 grams off...

    While I am waiting for the mirrors to arrive and see what they weigh, hopefully less than OEM mirrors, I had time to fit the volt meter today. Made the bracket last week and left it over the weekend for the paint to cure. Adding weight is the opposite to what this build is about however, my...

    what did you wrench on today??

    With a lithium battery on board, management/monitoring of the charging system is critical if you want warning of potential problems with an over-charged battery. The battery I have is 15 volt max so it's time to install a volt meter and to keep things tidy it will sit beside the engine oil temp...

    Next thing to go on a diet will be the mirrors. Right now the Kat is fitted with genuine Suzi mirrors and being genuine they are a quality part however, that quality includes weight. I found a set of used Barrac mirrors with aluminium stems, compared to the OEM steel stem these should be lighter...

    1981 GSX1100 Katana Based Project

    Now that the Project is a going concern and is performing well, there is now time for some tweeking to shed some grams here and there when any excess weight is identified. There is no bar buzz being generated throughout the rev range so the bar end-weights can go as well as cutting 20mm off the...

    Took the Kat out today to test the modified (lighter) seat pad for a two hour ride and so far so good. The new seat pad is smaller in area and 26mm thinner and has lowered the riding position. Although the seat pad is thinner the ride was very comfortable and in fact is more comfortable compared...

    I don't know the weight of an 11E centre stand but a Kat centre stand with bolts, bushes and spring is 2,330 grams so the centre stand is long gone from the build. The centre stand is the lowest bit of hardware (not including wheels) so its effect on the C of G would be minimal compared to...

    Not yet! The running tally numbers are for dry weight which is fine however, there is no fun with no fuel! After test rides to check fuel consumption it works out that 13 litres of fuel gives a range of 219.375 km. Using those numbers I can reduce the fuel load from a full tank of 21 litres...

    There may not be any big ticket items left to modify or delete to save weight however, there is always something that can be worked on. This week it is the seat pad. This is the first version for the seat pad and although light it could be lighter. Seatpad1 by Max Mutarn, on Flickr The...

    what did you wrench on today??

    I like to give the chain and sprocket a wipe down each month to prevent the old chain lube building up and gumming up the works. Cleaned the chain and sprocket today before new lube on the chain. Chain Sprocket ajpg by Max Mutarn, on Flickr Chain sprocket b by Max Mutarn, on Flickr
