Gregg

We are heading out of state for wrestling this weekend. If Bill doesn't come up with one let me know. I can start taking the lower cases apart.


Sweet.  He said he's looking today, and I don't think he has to split a motor to find one...I'll let you know ASAP!

Thanks Dude!

The ayes have it, and the minutes shall reflect it.  Bill is the man 8)




I counted and bagged up all 370 nuts, bolts, washers, springs, and various bits and pieces to be zinc plated, but when I called down to make sure the boss was there to give me an estimate, he (the boss) told me that the last guy I talked to was confused and they don't actually do zinc plating, only nickel...well, that's not exactly what I need, so he directed me to a place a little further away, which was nice of him.  When I called the guy a little further away, he was a jerk on the phone, so I decided to check the reviews on him...well, he's apparently not so great to deal with..so unless I want to mail off every single fastener for this bike, I'm stuck doing it myself.  I'm buying the '8' bolt kit from Yamiya, and probably buying a caswell kit for the other major visible stuff like the C-stand hook and spring, the brake pedal spring...basically as many pieces as I can.

I know nickel would not be correct but would it look different than zinc? Better??

Different, I don't know about better.  I bought a $35 caswell kit off ebay that should let me do what I need, and the Yamiya bolt set.  Yamiya has available ruby red painted fork ears, but only right sides, for $45...I picked one up as a spare.  The full left/right side painted set they sell is $250, and the painted lefty isn't available separately ??? ???

Great thread Greggo!

Spent a few hours reading every post from the first to the end of page 12. Looking forward to starting page 13 when I know I have a few uniterupted hours to spend. The SOHC site and the people on it impress me more and more each time I visit. Makes me want to learn all the upload pics from smartphone to computer,join and upload to pic hosting site,figure out how to get'em over here,compose posts that have partial quotes from multiple posters ect ect ect

Nice Work ! looking forward to see what I've missed in the past months.

I have the second batch of fasteners at the platers right now.  The first batch came back looking so good I can not tell them from new old stock.  I'll let you know how this batch looks when I get them back.  Turn around was 3 weeks for the first batch and there is an $80 minimum.  Contact Derek Baker at Plating Specialties, Inc.  1675 East Ten Mile Road, Madison Heights, MI 48071.  248-547-8660   www.platspec.com  derek@platspec.com

Update:  Second batch came out as nice as the first.  Sent 260 parts and total was $115.  Turn around was 3 weeks.

Yup. The left one is very difficult to find.  I have a right NOS red one as well and haven't been able to find a left one in a number of years.

My bottom end is buttoned...new crank bearings, all new transmission bearings, new primary chains/tensioner, new cam chain...Torqued it down and everything spins freely.  Primary chains are staggered...I made sure the gears shifted with the drum before I put the cases together, and I triple checked everything else to make sure I only have to do this once. 

I got my Yamiya bolt set (I frigging love their customer service/speedy shipping) so I took the lot of painted bits home from the shop to put some sub-assemblies together.

Yep :D   I was intimidated at first, but I think I got it all right, especially the two big gears like Mark points out in his book.  They have to be taken off to get the countershaft out of the bottom case, and it's easy to reinstall them backward (I did), causing them to rub...but I know I got them in there correctly now.

Grab it, even if it's a low number diecast ;)

I can see why you said you like putting the bottom ends together so much.

Well, look at what showed up in the mail yesterday ;D ;D  It's the never ending project!!  This one needs a full rebuild with fresh everything :o



I was going to have to buy all new valves/springs/keepers/guides and do a valve job on this head in the above pic, then Bill Benton told me he had this available...Well, what do you think I did...SPEND MORE MONEY ;D ;D  Well, at least I have a decent sandcast head to sell and recoup the costs ;)

I'll do a leakdown test, and if it's good, it gets paint and goes on! ;D ;D  It has S&W springs and keepers!

Mailman left me two boxes from you! Will open .....now! ;D Thanks, I believe that head will clean up good. Recommend disassembly, clean, check guides, probably no seals on ex side. Replace intake seals, check and or surface head and put that puppy on, but please clean it first. Lapping in valves probably all it'll need besides what's been mentioned. Oh yeh, check all threads! ;) ;D Need seals, I should have some.If you need studs or exhaust spigots , same. 8) Bill
Got a 2 hole hub anyone in need!

I tried out the Caswell plug & plate brush zinc plating kit, and was not impressed.  I bit the bullet and took my stuff to a local place after somebody through my dad's shop told me he'd had good results with his Porsche parts through the same place.  If they do a great job, I'll post a review on yelp to counter the horrible one that steered me away from them.  I got quoted $135 for the entire lot, with the environmental fee, and he said it'd be done next Wednesday  :o :o
