THIS IS NOT A FULL REPLACEMENT KIT ... ONLY A SELECTION OF PARTS TO ASSIST A CUSTOM BUILD
Additional work and spacers maybe required
This is for Sportsters 1991 up ( 2004 up may require additional work ) engines with seperate Taper Bearing to outer races type wheels ( NOT 2000 up sealed type ) with a hub exceptence of 1.985" I.D. sprockets.
This may well be all you will need, but often with so many model variables and requirements, you may need other parts to complete the installation. Treat this as a starter to offer up to see what you may or may not need, we will work with you to finish the job, by excepting parts back and supplying spacers or other sprocket combinations as required. Also great for working out to clear wide tire use, as this sprocket can be installed the other way around to create an offset for a wider tire use.
To work out these requirements.... measure with a straight edge onto your outer face of the rear sprocket, already fitted on your wheel ( with clearance for your chain to tire ) centered and squared in your frame. Measure the distance from from the same edge in contact with the rear sprocket outer face, to the exposed mainshaft bearing.
If required.... we have a seperate listing for new sprocket nut ( NOT included in this listing ) as well as a listing for a high tensile Allan cap screw ( which is now included ) for locking the sprocket nut in place.....see photo below to show installed position.
You may require some additional spacing work ( send us a working drawing of dimensions if required ) these we can supply for around £20 for the transmission and from £30 for the rear wheel.
We also have available the following transmision sprocket spacers 0.600" ( approx 15 mm ) & 0.750" ( approx 19 mm ) & 0.840" ( approx 21 mm ) width.
We also have available sprockets for wide tire use in our other listings
