kdotlowe Posted September 9, 2018 Share Posted September 9, 2018 Well technically my girlfriends. Since riding on the back of my motorcycle through Vietnam, my girlfriend has expressed interest in learning to ride a motorcycle herself. Always keen to crowd my garage with more non-running vehicles, I swooped up a pair of YB100s from the Moped NZ Facebook page. Good excuse to buy a 2 stroke, cause I’ve been pining for one for a long time. The first one is complete with live rego. Recently failed a WOF on fork seals and brake shoes - so nothing major. The plan is to keep my hands off it! I’ll pillage the front fender off the second bike, flip the handlebars back over and have a completely standard bike for my girlfriend to learn to ride on. Would love to completely restore it one day. The second one is in bits, but it looks like everything is there. Registration status is unknown. 2 Quote Link to comment Share on other sites More sharing options...
Popular Post kdotlowe Posted September 9, 2018 Author Popular Post Share Posted September 9, 2018 https://youtu.be/GHKt-AbF_wg Goes hard for what it is etc. Pulls my fat ass around pretty well. Think I'll struggle to get it over the Harbour Bridge though. Robbed the handlebars and rear wheel from the parts bike and spent FAR too many hours replacing the fork seals. Fresh WOF, fresh rego = happy girlfriend, ready to learn how to ride! 10 Quote Link to comment Share on other sites More sharing options...
kdotlowe Posted September 11, 2018 Author Share Posted September 11, 2018 Decided to go balls deep on the spare engine. I've had a fair few motorcycle engines apart, but I've never had them down to the bare cases. Time to learn a thing or two. I also need to find out why the engine was in pieces in the first place. I can only assume something is broken or something is missing. Started stripping, bagging and tagging. 3 Quote Link to comment Share on other sites More sharing options...
kdotlowe Posted September 11, 2018 Author Share Posted September 11, 2018 Found a problem! Now the scavenger hunt begins for a new one. Stripped the carbs which had the the most disgusting, gooey, varnished fuel covering everything. Will give it a dunk in the ultrasonic cleaner. Also managed to get the crank out with a bit of persuasion. Super excited to send the cases off to get vapour blasted. Now on the hunt to find replacement bearings & seals. 5 Quote Link to comment Share on other sites More sharing options...

kdotlowe Posted September 15, 2018 Author Share Posted September 15, 2018 Carbs came up super nice after 15 minutes in the ultrasonic cleaner. Also stripped the rest of the bike down. 3 Quote Link to comment Share on other sites More sharing options...
MichaelJFox Posted September 17, 2018 Share Posted September 17, 2018 Shit yeah. I hand cleaned everything, what a waste of time haha. I almost did the bridge the other day, but then ended up taking the seats out the Corolla and taking it over, never again. Might just risk the biscuit next time. 1 Quote Link to comment Share on other sites More sharing options...

kdotlowe Posted October 7, 2018 Author Share Posted October 7, 2018 Been a little distracted with another new bike purchase. However, nearly all the parts have arrived to do the bottom end rebuild. Just waiting on one more bearing and trying to find a replacement shift fork.Shout outs to Yambits for being a helpful bunch! 3 Quote Link to comment Share on other sites More sharing options...
kdotlowe Posted November 20, 2018 Author Share Posted November 20, 2018 Engine case are away getting blasted & powder coated. My new shift fork arrived all the way from Florida. Rebuilt the shift drum, and pulled apart the transmission to ensure everything was in the correct order. 4 Quote Link to comment Share on other sites More sharing options...
kdotlowe Posted December 12, 2018 Author Share Posted December 12, 2018 Fresh out the oven! Ready to start assembly. 7 Quote Link to comment Share on other sites More sharing options...
kdotlowe Posted December 15, 2018 Author Share Posted December 15, 2018 Installed the new bearings today. Baked the cases for 45 minutes in the oven and left the bearings in the freezer overnight. Dropped in easily! Installed the transmission to make sure there was enough clearance to seal the case halves. Couldn't figure out why nothing would line up - turns out when I replaced the shift forks I accidentally put them in the wrong order, oops. Couldn't figure out why I had no first gear, and spent an embarrassingly long time trying to solve it. Until I remembered this bike has a GP shift pattern with N at the bottom. Doh! Will install the crank as soon as possible but judging by how hard it was to remove, I think I'm going go need a crank puller tool. Anyone have one I can borrow? 2 Quote Link to comment Share on other sites More sharing options...
kdotlowe Posted December 25, 2018 Author Share Posted December 25, 2018 It's Christmas time and I'm poor so I'm waiting till the new year before I splash out on some crank installer / case splitter tools. In the mean time I've been cleaning and painting bits and pieces to keep the progress going. Oh and I bought a brand new exhaust header & silencer from China... FOR $15. Postage is around $80, so less than $100 for a brand new exhaust - I wonder if it will actually fit? 5 Quote Link to comment Share on other sites More sharing options...
kdotlowe Posted January 11, 2019 Author Share Posted January 11, 2019 Tusk crank puller tool arrived today and made easy work of installing the crank. Not a cheap tool, but I think it will pay for itself if I'm rebuilding engines frequently. Can't seem to find any Yamabond locally and Threebond is ridiculously expensive so I may have to order some online before I can seal the case halves. 3 Quote Link to comment Share on other sites More sharing options...
