Gixer1460 Posted August 2 Posted August 2 Just from the lack of spatter says this is quality welding, so nice to see! The headstock mod seems 'sensible' but when my Z1000 frame got used in the Kawazuki, the 1100L upside downies were almost TOO steep without any mod to frame - the difference in fork length and wheel size from 19 down to 17 was quite dramatic!

LLD Posted August 5 Author Posted August 5 (edited) So, for a little background.......... Last year i started with roundy round racing as I was looking for a way to use the GSX stuff i have collected over the years. As a Katana enthusiast there was no question what it would be and we (my best mate and myself) started to run a mildly modified Katana which we acquired in Germany. Although it is a very nice bike, it had a few issues: it was only one, which makes it difficult with two guys and the frame was quite wobbly under heavy braking. So the idea of building a second Katana came to be, with the intention to use it in Classic Endurance competitions. Edited August 5 by LLD 3 Quote
LLD Posted August 5 Author Posted August 5 So, the targets for the second one were: stiffer frame better front fork stiffer swing arm use FRP rear body work with OEM styling instead of the Speer based parts The modifications on frame were shown in the pics before. Reinforcements in the common places, adjusting the front fork angle with 2 degrees and lowering the swing arm pivot with 5mm. The latter had to be bored out anyway to make room for the TL1000R swing arm. Moving the pivot point helps improving the angle of the swing arm. Besides that the mounting points for the rear shocks were reinforced and repositioned so that shocks can be mounted parallel. 4 Quote
LLD Posted August 6 Author Posted August 6 Because I am combining so many different parts, many brackets, bushing and adapters had to be made. A nice opportunity to test my new 3d printer to make test pieces before I send the drawings to my machinist. In this case it were some pieces to mount the slabby rear wheel into the tL swing arm. A special axle block was designed and tested in 3d before having them machined. The inside plate was a new lasered piece to deal with the much thinner rear axle. With the 3d printer I can make several interations in a matter of few hours, without the need for a full machine shop and spending hours in machining itself 5 Quote

LLD Posted August 7 Author Posted August 7 (edited) On the front end it was not different. I choose a YZF600R Thundercat fork as it is a relatively modern, right side up and 41mm fork. It is also much longer than for instance a R6 fork, which make it a bit easier to achieve the correct stance 41mm as that is the maximum in some series we would like to run. But with the advantage of some nice 4-pot brakes To end up with reasonable trail I choose to use Slabby yokes which were almost a drop-in in the GSX frame. In order to mount the Slabby wheels, because they are 18" and cheap, I made some spacers and used ZXR750 discs. I hate to modify wheels itself, as it makes swapping more difficult, so I designed some spacers to accommodate the ZXR discs on the Slabby wheel. Again some tests were printed before committing the design to the machinist Edited August 8 by LLD 2 Quote
