kdotlowe Posted January 13, 2019 Author Share Posted January 13, 2019 Titanium bolts for the side covers, for no reason other than they look sexy. 6 Quote Link to comment Share on other sites More sharing options...
kdotlowe Posted January 15, 2019 Author Share Posted January 15, 2019 Sourced some Threebond and sealed the cases. Installing the disc valve cover & gear selector. Looks like I'm missing a bunch of circlips and other misc hardware. Will have to dig around the box the engine came in to see if I can find everything before I can continue. 3 Quote Link to comment Share on other sites More sharing options...

kdotlowe Posted January 15, 2019 Author Share Posted January 15, 2019 Found a box full of misc parts which contained some of the parts I required - the joys of building an engine from a box of parts. There's a few variations of the YB100 with mine being the earlier model. Seeing as this engine was in pieces when I purchased it, I'm not sure if a piece I can't find is missing or just not needed. Currently referring to 2 seperate schematics and unfortunately my engine seems to have pieces from both... Installed the kick start shaft after a bit of fluffing around with gear orientation. Also installed the clutch basket. Turns out my clutch plates are at OEM measurements. No wear on them at all. I'll be using them again so I've left them in some oil to soak overnight. 2 Quote Link to comment Share on other sites More sharing options...
kdotlowe Posted January 16, 2019 Author Share Posted January 16, 2019 Clutch plates all installed. Oil pump assembly installed. Love installing parts when they're all clean & freshly painted. 6 Quote Link to comment Share on other sites More sharing options...
kdotlowe Posted January 17, 2019 Author Share Posted January 17, 2019 I've been busy. Missing one titanium bolt which is heartbreaking but hey, that's the right side done for now. 9 Quote Link to comment Share on other sites More sharing options...
Truenotch Posted January 17, 2019 Share Posted January 17, 2019 You’re doing great work! I’m taking notes for my MX100 rebuild soon... 1 Quote Link to comment Share on other sites More sharing options...
kdotlowe Posted January 17, 2019 Author Share Posted January 17, 2019 @Truenotch cheers bro! Looking forward to your build thread! Got carried away and installed the points/magneto. Realised that I need to find a replacement side emblem, mine is bent to buggery. Also placed an order with Yambits for a 0.75mm oversized piston. Toyed with the idea of going 2mm over, but I think I'll keep it conservative for now. Once the piston arrives I'll send the cylinder off to get a re-bore and hone. 4 Quote Link to comment Share on other sites More sharing options...
kdotlowe Posted January 20, 2019 Author Share Posted January 20, 2019 Gave the wiring harness a once over. Other than a few crusty connecters it was in surprisingly good condition for the age. Also cleaned up the air box ready for some polishing & powdercoating. Quote Link to comment Share on other sites More sharing options...
kdotlowe Posted January 29, 2019 Author Share Posted January 29, 2019 $15 dollar exhaust arrived and it looks just as you'd expect - like a $15 exhaust. I'm happy enough. 1 Quote Link to comment Share on other sites More sharing options...
kdotlowe Posted January 31, 2019 Author Share Posted January 31, 2019 Shout out to Yambits! +0.75 piston arrived alongside and new small end bearing. Cylinder and head are off next week to get blasted. Once painted the cylinder will be off to the machine shop for a a fresh bore & hone. 3 Quote Link to comment Share on other sites More sharing options...
kdotlowe Posted February 14, 2019 Author Share Posted February 14, 2019 The end is in sight! Blasted head and cylinder. Once machined and installed the engine will be complete! 3 Quote Link to comment Share on other sites More sharing options...
kdotlowe Posted February 20, 2019 Author Share Posted February 20, 2019 Look what we have here. Had to do a mock up after painting the cylinder and head. Off to the machine shop tomorrow. 7 Quote Link to comment Share on other sites More sharing options...

That was vapour blasted - well at least the head was. Done through a guy called Darth Vapour. 1 Quote Link to comment Share on other sites More sharing options...
kdotlowe Posted February 25, 2019 Author Share Posted February 25, 2019 Making a start on the bodywork. Pulled out the swing arm and lower shock bushings which was an absolute bitch. Using a ghetto method of hot glue and a socket extension to pull out some of the tank dents. It's surprisingly working. What's everyones thoughts on powder coat vs paint? I want a good finish and the frame, side covers and tank will all be colour matched. Is powder or paint cheaper? (I suck at painting so don't want to do this myself).

xsinclairx Posted February 25, 2019 Share Posted February 25, 2019 Not sure which would be cheaper but powder covers a lot of imperfections easily. The down side is that it looks thick if that makes sense. I got my frame and bits coated but personally think paint would look nicer. 1 Quote Link to comment Share on other sites More sharing options...
