You can rebuild an engine quickly or you can take your time and be anal as fuck.\u00a0 That’s why it has taken me so long to post this final follow-up (Part 2) to my KZ650 Performance Project. \u00a0Truthfully I just took my sweet ass time while still being anal about every step. \u00a0See Part 1<\/a>\u00a0to get caught up.<\/p>\n I started with a barn find\u00a0KZ650 and ended up with 700cc bore race cam equipped rocket. \u00a0I kid you not…this thing hauls ass. \u00a0It’s still being broken in so I’ve been hesitant to rev it over 5k rpms but man does she go. \u00a070+ mph at 5k rpms and pulls strong! \u00a0Redline is at 9k….shit I am in for a surprise when I get there.<\/p>\n Here is a list of work\/mods\/upgrades with KZ photo porn to follow:<\/p>\n Here is where I left off. \u00a0Polished the engine covers. \u00a0Two Dremels saved my life trying to get that valve cover to looks so nice.<\/p>\n Used a K&L Motorcycle Engine Stand for the rebuild and installed new crankshaft bearings as shown covered in assembly lube. \u00a0If you look closely I nearly made a mistake during\u00a0assembly. \u00a0The right most shift fork has a guide pin sticking out of it. \u00a0That pin is suppose to be recessed to meet up with the shift drum guides. \u00a0Turns out I had it reversed.<\/p>\n I used a little bit of carb cleaner to ensure the case halves were free of contaminates before sealing. \u00a0There is big debate about what sealant to use but Hondabond worked just fine. \u00a0The trick is to apply a thin coat. \u00a0Once the case halves are mated the the rest will squish out. \u00a0Applying too much can create major problems and potential clog important oil passages. \u00a0Red stuff is assembly lube…goes on gears and smooth bearing surfaces.<\/p>\n Not shown in the picture but during the case mating process the most important part was\u00a0to make sure the shift forks line up to their respected gears on the other half. \u00a0A second person was critical in this setup.<\/p>\n Using two pieces of cardboard I was able to create a tool that allowed me to install the Wiseco K700 Pistons (+2mm) with ease. \u00a0I’d highly recommend watching techniques on how to install circlips<\/a>\u00a0on the ends of the piston. \u00a0It’s to easy to damage a piston during this process if you don’t have the right technique.<\/p>\n Dropping the block on to the pistons took two people as well. \u00a0A ring compressor wasn’t needed but it can be done by slowly squeezing each ring into their cylinder one by one. \u00a0Each ring gap has a specific position it needs to be facing. \u00a0This step is very important.<\/p>\n Installing the head and\u00a0cams was easier than I expected. \u00a0Setting the timing on the camshafts was simple\u00a0with the service manual.<\/p>\n WARNING<\/strong>: \u00a0Be careful with over tightening the bolts on the camshaft caps. \u00a0With these old bikes its a common problem for them to strip. \u00a0I had to replace 2-3 using Helicoils.<\/a><\/p>\n Installed a ZX6E tailight and LED blinkers with LED flasher relays – look great in action!<\/p>\n\n
