Coming back to the DW versus Curb weight quoted by Suzuki, I believe all Japanese manufacturers in the 80's quoted the DW without any liquid on board i.e; not only fuel but also oil and coolant if any.
This explains the difference between the two measures.
A marketing gimmick as when KTM annouces ready to ride weights with very little fuel in the tank...sigpicJohn Kat

Time to choose an oil cooler from the spares pile.
Oil cooler 1 by Max Mutarn, on Flickr
The lightest cooler from the pile is a transmission oil cooler so that will be the 1st cab off the rank. Temp gauge will show how effective it is.
Oil cooler 2 by Max Mutarn, on Flickr
Making the lower bracket for the oil cooler from some scrap ally square section.

After the lower bracket is installed and the cooler fitted I'll be able to work out the top bracket.Last edited by Shin-Ken 1074; 03-29-2024, 09:56 AM.Badgezz, we don need noh stinkin' badgezz!

The cooler needed some work with a flaring tool to sort out the hardlines, good to go now. Cooler position doesn't foul on brake lines, speedo cable or steering lock to lock. So far so good.

I wanted a decent sized gap between the cooler and frame to allow unrestricted air flow. The OEM cooler bracket is more of a plate than a bracket and its positioned very close to the cooler with not much of a gap to bleed away heat so the OEM bracket is out and in with the DIY aluminium bracket.

Cooler sits neatly within the body panels and in the air-stream between the forks.

The plan is later today to drop the engine oil and install the hardware for the oil cooler including the all important EF oil filter cover used when running an oil cooler. Haven't weighed the cooler parts yet, adding weight is no fun!

Remind us please what engine you're running. 1074 is in your name, but for some reason I thought you were working with an 1135 (which came with a cooler so naturally also the proper oil filter cover).

The build has the 1135 EF engine installed. I removed the oil cooler to record engine oil temps while test riding and although the oil temps without the cooler are below the range Suzuki state for operation of an air-cooled GS I am fitting a cooler to check the temp difference.Badgezz, we don need noh stinkin' badgezz!

So didn't your engine already have the correct filter cover?1982 GS1100E V&H "SS" exhaust, APE pods, 1150 oil cooler, 140 speedo, 99.3 rear wheel HP, black engine, '83 red

Installed the cooler today, adding weight is not my idea of a good thing but for testing it has to be done. The total weight of cooler and hardware came in at 864 grams so the running tally needs an adjustment. I will off-set the weight of any additional parts that are bolted on by reducing the fuel load. One litre of fuel = 767 grams. Once I find out how thirsty the DW is I can work out how much fuel I can off-load. Aiming for a ride weight of 198 kg for the Kat.
