Soooooooo. I decided to just completely rebuild the bike from the frame up  ::)

I stripped it down and sent the frame and swing arm to a sandblaster:


I hung them from a wire for a makeshift paint booth:


My girlfriend walked out and asked where my motorcycle was... she rolled her eyes at my now TWO projects..


About 4 coats of Eastwood Chassis Black:



This is far as I got on the engine tear down.  I am just going to clean, paint and install a 650 cam:


Cylinder is black VHT, Planning on block sanding the fins.


Of course I had to test fit some of the pretty parts =)

Are you aiming to keep the stock functionality of the hinges and just shorten the overall seat?  So much for stock!!  :o

Might be a stupid question, but I can not find any reference to which engine mounting points are the grounds (unpainted).

Is it just the back two that make direct contact with the frame?   ???

Is there a downside to having more than just that one ground point?

For some reason I thought it was the bottom rear two as well, so I have all three of hose unpainted...

The battery only has 1 NEG terminal. It only needs 1 ground point.

I got the whole motor reassembled and put in the 650 cam.. but then I realized I forgot to put in the two hollow dowels that go between the cylinder and the head... The step by step I was looking at didnt use them and I didnt notice them until I was cleaning up my bench.

son of a BETCH.

ok... so I used a brand new OEM base gasket and head gasket, with permatex copper spray in both. I also used hondabond on the new pucks, so it is sealed up nice.  My question is...

Do I need to run those dowels? If not necesary should I just leave it as is since everything is sprayed and torqued?  If I do have to run them, can I reuse my brand new head gasket?

this is a bummer  :-\

Bryan, I don't have a qualified answer on the dowel pins so I won't opine, but I will say, 'been there, done that' in similar fashion, and whether or not they speak up, I bet a dozen ore more guys that read this are saying it too. Re your head gasket, if it is MLS I personally think the answer is no on reuse, and yes if it is copper. Paper gasket, unknown, but if it isn't damaged when you pop the top off, I am going to GUESS that reuse is fine.

Thanks!I actually was watching the soco videos and actually found him on this forum and someone else said "hey I built my motor watching your video but I dont think you used the alignment dowels between the cylinder and the head" he responded with "im not sure what you are referring to' then the thread died  ::)

 I used the stock OEM gasket that is the waxy/graphite looking thing. Im not sure what it is made from. its not the aftermarket MLS though

"Of all tyrannies, a tyranny sincerely exercised for the good of it's victim may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated, but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience." - C.S. Lewis
