I've been hooning this thing a bit. 

ran into my first issue which was the lights stopped working and we couldn't find where in the original loom the break was so ended up just wiring the headlight and tail lights straight to the stator through the trail tech which worked a treat and that also ment i could ditch all the original handlebar controls and ignition switch and rip out the entire old loom which tidied the bike up a whole heap. 

bike ended up dieing on me on my way home from work and had to push it home, it had lost spark so i pulled the side cover off and turns out one of the screws out of the stator had made its wat out and had a bit of fun behind the flywheel and knocked the points and one of the windings. so i chucked my spare stator in and after mucking around with the weird timing advance setup these use managed to get it going just in time for the penny pincher's first big ride.

We managed to travel around 550km's over two days all on back road and gravel which was  super fun my bike ended up making it to the lodge where we stayed the night then when i when i was full cut and tried to start it to do a drunken skid as ya do there was no one home and we couldn't get it to fire up at all the next day which was lame, have a feeling something to do with the points is fucked again so it may be time for a xr100 motor with a cdi setup for reliability. 

i ended up riding one of the other boys a50's on the way home and that was a great time, really have to work hard to keep those things humming up hills and just in general.

Note: the Irvine's mince and cheese pipe sitting on the engine casing, i recommend 50km  @9000rpm to warm i through throughly

Next plans for the bike are to get it going reliably, ride it more, i am wanting to play with a fibreglass mould for a new seat pan and recover it in some brown leather, also i managed to destroy the speedo drive in the original speedo on this ride so may end up getting some nice small desecrate  rev and speedo gauge, also get a good quality tail light as the aliexpress ones seem to rattle apart easily this being the second one i have killed.

i should probably update this more. 

Junked the xl100 motor as i couldn't be bothered with stators etc anymore and bought a 1992 xr100 motor, got it bored out to 54mm and chucked a fresh top end in it for DGR bike was running super rad at DGR until the last 10mins it wouldn't rev above 5k rpm and was making a hell of a top end noise, got home and pushed it into the corner in the shed and gave up for a bit.

It was wicked fun hooning with you over Te Urewera. This little beast is impressively quick and seems to handle the gravel with ease. Can't wait to smash more gravel with you dudes in the future.

east cape is coming up so thought i better actually fix this from last year/make it faster. 

started off by making up a new seat and brackets to hold bits and pieces this weekend, will fire it down to Lewis and he can work his magic on it for me.

then stripped it down to a bare frame and packaged all the bolts up to get sent off to get re zinc plated.

will do the standard sandblast and powdercoat for everything to tidy it up.

next is motor work, big carb upgrade, stainless exhaust etc. will see how motivation goes and how distracted i get by other projects
