clivegto Posted June 24, 2017 Posted June 24, 2017 Got a gsxr 1000 k9 bottom yoke. Had a bottom bearing that fit but no top one. The yoke needs reassessing as the stem is about 6mm to short & steering stops altering. 1 Quote
Dezza Posted June 25, 2017 Posted June 25, 2017 I have GSXR750Y forks and yokes, which are very similar to most of the later 750/1000 items, and yes indeed, to fit them to a Magnum 2 frame the stem has to be changed as the stock one is too short. Quote

clivegto Posted June 28, 2017 Posted June 28, 2017 There's not enough material on the bottom yoke to sink the stem in on the k9 yoke so tried a slingshot yoke stem which is too short as well. I then tried b12 stem which is too long so put part of the k9 bearing on to shorten it by 11mm which makes it just about right. Am thinking get a spacer made to fit the bottomside of the yoke. Last pick is with a b12 top yoke just for mock up. Or better still get one made. 2 Quote

clivegto Posted June 30, 2017 Posted June 30, 2017 (edited) Went on a road trip to see Sam, took the frame with me as well. (cheers mate you are a star as always). After nearly 5 hours we came up with this. Edited June 30, 2017 by clivegto 4 Quote
clivegto Posted July 2, 2017 Posted July 2, 2017 Pressed it together went to fit the forks only to discover that the bottom yoke is 1mm smaller than the forks so will have to get them milled out. (K9 yoke k8 forks). Quote
Dezza Posted July 2, 2017 Posted July 2, 2017 Are you using GSXR1000 forks? If so raising the yoke relative to the top of the headstock will 'pull the forks up' by a distance that equals the width of the spacer. I hope this does not mean that the front of the bike sits too low. I think my 750Y forks are probably the same length as 1000 forks and I have them about 2mm below the top of the top yoke and they are just about the right length but the bottom of the top yoke has the protrusion on underside where the stem passes through milled down by a couple of mill and it sits much closer to the top of the headstock.

clivegto Posted July 2, 2017 Posted July 2, 2017 (edited) @Dezza yes gsxr 1000 k8 forks which are 720mm from wheel spindle centre to top not including adjuster on the top of the forks. What do your 750y ones measure, I don't know what length the forks were on the first Harris magnum 2's was. If the k8 forks are shorter than what is needed I can always do this in the pic below.

clivegto Posted July 3, 2017 Posted July 3, 2017 I returned the 2 right hand side silver spot calipers to the breaker & they sent me a right & a left set of gold spots. Am happy with that. 1 Quote

Gsxrsam Posted July 3, 2017 Posted July 3, 2017 The forks........750 and 1000 are different sizes...... Quote
clivegto Posted July 4, 2017 Posted July 4, 2017 Bottom yoke was sold to me as gsxr 1000 k9-L0. Quote
clivegto Posted July 4, 2017 Posted July 4, 2017 (edited) Hoooo bludy Raaaaa, have a 1000k8 bottom yoke from one of Sams mates for little money. Have not got time to press the stem out tonight as have to take Mrs gto out for a meal. Any one need a k7 or k9 one lol. Edited July 5, 2017 by clivegto 2 Quote
clivegto Posted July 5, 2017 Posted July 5, 2017 Any one know the length of the forks harris first fit to the magnum 2. Quote
Swirl Posted July 5, 2017 Author Posted July 5, 2017 I got the forks that were on it mate, dont reckon it was built in the first place with them on as there usd kawasaki of some sort, chrome was properly destroyed on the stantions, willeasure them later Quote
clivegto Posted July 5, 2017 Posted July 5, 2017 Popped the k8 spindle out & fitted the moded one along with the rest of the front end. Comparing it with my NWS slabby the forks are 40mm longer but with the extra spacors below the top yoke 18mm which makes it 22mm taller than the NWS with the forks flush on the top yoke. 2 Quote
