+This little bracket is the cure for broken sprocket covers and mountings on kickstart 1977 models. \\
+It can also be fitted to pre-1977 models with minor modifications to the sprocket cover. \\
+It is standard equipment on 1978 kickstart models and was issued by HD as a retro fix kit for early 1977s. \\
+HD OEM part number for the spacer is (34848-77). \\
+But they are not easy to find, so making one is a real option. \\
+It would just take two pieces of flat steel strap and a piece of 3/4" water pipe, some drilling and some welding. \\
+It basically bolts to the two rear engine mounting studs and sticks out around the kicker shaft so the cover can bolt to it. \\
+Mid-77 models have the extra bolt hole in the cover. \\
+Earlier models will need a patch welding inside the cover and drilling. Easy enough to do. \\
+**Pics: The "spacer` as HD calls it**. \\

+**Installed on the bike**: \\
+Note the 1/4" bolt, pointed to, goes through the sprocket cover. \\
+Nuts are yet to be put back on the rear engine mount bolts. \\
+Looking straight down from on top, there is a divot ground in the tube where the rubber oil supply line will go. \\
+The bracket itself seems good and solid. The tube is thick walled so will not flex. \\

+And here is the factory support bracket fix kit in place around the kick starter shaft. \\
+Also my extra support bracket on top of the gearbox casing, ready to bolt the sprocket on when it arrives and then the cover. \\
+Third pic I of the top bracket before I drilled and tip it in position. \\
+Nice welding job by my aircraft welder buddy there. \\

+I shaped and had welded a piece of a 3/8" aluminium plate inside the sprocket cover. \\
+And then drilled a hole for the spacer bracket mounting bolt to go through. \\
+Covers before mid-77 will need this attachment point. Aftermarket covers for 77-78 will have this standard. \\
+Third, pic: the modified sprocket cover, welded, filed down and drilled to suit the factory support bracket spacer. \\
+It is easier to just buy an aftermarket 1978 sprocket cover, it already has this in place. \\

+Then I made a big extra angle bracket to go from the bolt holes on top of the gearbox, over to support the top bolt on the sprocket cover. \\
+(which I enlarged to 5/16" to make it stronger) \\
+Make sure it has the bit sticking out at the top so the angle does not hit the chain. \\
+I also had to make an extended gearbox breather fitting to allow for the bracket being fitted underneath it. \\
+It is just a bolt with a hole drilled in it and an old piece of metal brake line silver soldered in. \\
+As well as this, I had my gearbox casing welded up and redrilled the wrecked original dowel holes, but I reckon that with these two brackets, that step might be optional.

+And I did have to grind a little clearance on the factory spacer to allow for the oversize 22-tooth sprocket. \\

+**Dimensions of the spacer**: \\
+A rough sketch I made by laying the part on paper and drawing around it, then measuring up. \\
