Since I can't really get any parts or get any painting/powder coating for this at the moment (24 year old growing up in NOVA$$) I did manage to get a few things done.


A good friend of mine offered to do some work on the frame, so that's off at his house. In the mean time I managed to get the head studs out with a tip from calj737, heating them up till they are red, tap it with a hammer and they come right out.


Just. One. More.



So now that thats out of the way I'm kind of idle for the time being, hunting down a set of 18" aluminum rims at a good price isn't going anywhere anytime

Buchanan's Sun Rims are not an arm and leg. If you want cheap, try to pick up a used GL1000 rear wheel (uses aluminum rims).

As for GL1000 rims I am hunting down two rears per calj737's recommendation.

Actually, the GL1000 may have had 17 rears.  Make sure to check before buying.

I should probably just replace the front spokes for now, and later on when I switch out the front end to a USD get a nice set of sunrims front and rear to compliment the bike.

Small update, got a second job so I've been a little busy.. not so much on the bike. However a good friend of mine has been working the frame issue for me.





Everything is handmade and I couldn't be happier with the results so far. I've also just made plans with a friend who has expedience painting engines for once the lower case is split to get the case spiffed up.

I also made a little time to clean up my work space and garage.



I'm working up to splitting the case, pretty anxious TERRIFIED of it.

Started to do a little while I had some time this evening,


I already have a concern, the connecting rods have some rust on them.. is this normal and I can just soda blast them? OR should I try to replacement. As I've mentioned before I do not plan to do a very high out put engine, just a 836cc kit later down the road, for now I am keeping stock displacement.

Today I made some great progress!

Started with flipping the engine upside down over a recycling bin,


I also did this to keep track of the bolts, and rolled it up like an tool bag to keep them from sliding out.


Now I was starting to get in to the case, to my surprise it in very good shape, no hard build up and the rollers for the primary look great (to me?)


This fell out of the timing cover, not sure where its from HELP


And now I'm here,




So as far as I can tell nothing looks terribly out of place or worn, looks like I'm going to end up with a fairly solid little engine after this.

And a little more happened.

Maybe it wasn't the best choice to drill it out... one bolt out of everything so far isn't too bad!





Sharing a garage with three other people has it's down sides.. luckily everyone has been respecting my space with the build, I have good roommates.

The kindness of people is astonishing sometimes.
 Merry Christmas.

To give a small update on the build I packed up my engine and took it to soda blast and my soda blaster crapped out me, I will be on some what of a hold till I pick up a new one.
