Problem was,with the reduced height due to cutting them, the bars are now touchin the rear of the the fork tops,and restricting me from fittin the risers in the middle of the yoke,therefore my risers are overhanging the back of the yoke by approx 10mm ,which i will cut off to make it look better.
Also couldnt use the 2 threaded holes in the bottom of the risers,cos one would have missed the yoke, so drilled n tapped one in between.
The only way i could've fitted the risers on yoke without the overhang would have been to lower the forks by around 10mm,enabling the bars in the risers to clear the tops.
Too late now,as the're fitted
