 +Article by Hopper of the XLFORUM ((https://​www.xlforum.net/​forum/​sportster-motorcycle-forum/​sportster-motorcycle-era-specific-and-model-specific/​ironhead-sportster-motorcycle-talk-1957-1985/​52379-sprocket-cover-kick-starter-damage-repair-kit)) \\
  
 +This little bracket is the cure for broken sprocket covers and mountings on kickstart 1977-1978 models. \\
 +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). \\
 +It's in the -78A and -78B Parts Catalog in the transmission sections under part# (34850-77) - SPROCKET COVER KIT. \\
 +But the part number for the spacer is shown in the -78B catalog. \\
  
 +They are not easy to find, so making the spacer 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 77 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 is 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. \\
