rik1216 Posted February 28, 2018 Posted February 28, 2018 hi chaps dont shoot me i know this will have been covered a million times just point me in the right direction but !!! right cheap set of wheels and forks were aquired for the 7/11 so there going in front end mint no probs boooosh rear wheel erm right no probs swap bearings as the srad spindle is too large but on checking the bearing tables a rough guess at a 58x20x15 there not available so question 1 does anyone have a set of slingy bearings or boiler bearings if there different they can measure for me ? i,m tipping the spindle is 20mm second question is does anyone know the different widths of sprocket carriers that fit on different models , as you can see the wheel is quite wide :-) the motor is an m so has a slightly longer out put shaft but i need to se how much i,m playing with , cheers adrian Quote
bluedog59 Posted February 28, 2018 Posted February 28, 2018 Re Wheel bearings, perfect opportunity to fit "captive" spacers, makes wheel changes a lot easier. 1 Quote
dupersunc Posted February 28, 2018 Posted February 28, 2018 Captive spacers ftw. I'm told you'll need to machine a bit of the sprocket carrier and run an offset front sprocket to get the chain alignment, there's around 10mm difference in the rear sprocket offset between the Srad and oil boiler rear wheels. Though you appear to have wp stuff in the pictures. I'm doing this conversion myself in a week or 2. I'll do a little write up on it. 2 Quote
MeanBean49 Posted February 28, 2018 Posted February 28, 2018 Like Dunc says its not a straiightforward swap, Srad/TL/Busa and earlier K-series gsxrs all have a different sprocket offset to slingshots. Oil boilers are 100mm and the rest 110mm you need to account for this somehow otherwise you cannot have a central wheel with correct chain alignment. Easy soloution is a 10mm offset front sprocket if theres clearence. I use K series wheels and i had to do a lot of machining of wheel and carrier. I got 5mm that way, run a talon rear sprocket backwards got another 3 and there was space for a 2mm spacer behind front sprocket. I believe its easier to machine the outside face of the srad/tl/busa carriers than k-series. Other ways you can get clearence is using a 520 chain and sprockets, and spacing the front sprocket by the difference in sprocket thickness. Another tip is I always measure from the center of the standard wheel to the inside face of the sprocket and the centre of the wheel to the outside face of the sprocket carried spacer. You can then compare to the wheel you want to use. Sometimes the sprocket offset is ok but the sprocket carrier itself is too wide to get wheel central. I believe this is the issue with the Triumph 675 rear wheel Quote
Mole28 Posted February 28, 2018 Posted February 28, 2018 (edited) I've just done this. It is a Slingy but the dims same as a Slabby I believe. I had to make new tophat spacers on the outside and a new inner spacer for the carrier. I also machined a bit off the carrier sprocket face. Edited February 28, 2018 by Mole28 1 Quote
no class Posted February 28, 2018 Posted February 28, 2018 Won't fit...... can't be done ..... 2 Quote
Captain Chaos Posted February 28, 2018 Posted February 28, 2018 1 hour ago, no class said: Won't fit...... can't be done ..... who told you that? Boilerdude? 2 Quote
rik1216 Posted March 1, 2018 Author Posted March 1, 2018 Why Carney it be done ? Everything can be done :-) Quote
Madb Posted March 1, 2018 Posted March 1, 2018 agree with no class on this one. That's a 750wn/wp frame and swinger. 5.5 wheel is tight .6incher just won't it do this time. tho you could fit a later arm from srad 750. Quote
rik1216 Posted March 2, 2018 Author Posted March 2, 2018 they moved me to the watercooled section !!!!!! but my engine is oil cooled i feel violated :-) Quote
Captain Chaos Posted March 2, 2018 Posted March 2, 2018 yes normally the engine determines the section it goes in. But in this case it's about a watercooled wheel in a watercooled swingarm and watercooled frame. Not much to do with oilcooled IMO. 1 Quote
rik1216 Posted March 2, 2018 Author Posted March 2, 2018 Haha but why me my engine is oil cooled I feel like !!!!!! Well I feel hurt 1 Quote

I believe this is the issue with the Triumph 675 rear wheel hi sorry for the intrusion im building a bike with suzuki gsxr front strad wheel as i like the design , i also want to fit a 6 inch strad back wheel and im looking for 110mm from centre of wheel to back of sprocket , i just found this thread on back wheels on a strad 750 6j rim being that ,is this correct . again thanks in advance Quote
