Hi chevelle, sorry not to have replied earlier to you but I haven't been on here for a good while. I was made redundant from my job so things have had to take a back seat.
Once I really got into the engine & was able to have a good look there was so much that needed replacing. I bought a used Ironhead motor to cannibalise for the bits.
All the covers, primary, timing, rockers were shot, so was the primary drive & the clutch. Gearbox is o/k but worn.
I picked up a belt primary drive in great condition off ebay but don't know whether to stick with the chain drive, whats your thoughts on this?
Good news is crank, rods, pistons cams etc are brand new.
Crankcase are good except the steel insert in the primary drive side that holds the main bearing in. There is the groove where the circlip sits, that part of the insert has broken off so there is no way of holding the circlip in place.
I may have to engineer something.
Once I get sorted I'm hoping to start building the engine early new year, funds permitting. I'll keep you informed.

Hello, I dont know the quantity Sputhe put out. I have only seen 8 in photo's from the net.
My 77CI, I would guestimate at 90 rear wheel HP, never dynoed, I know its a hell of alot stronger than my 4&5/8 stroke XLCH.

My Friends 92CI Sputhe ran 124 HP on the dyno, he put a ton of effort into that engine / bike.
He actually wants me to buy his bike.
What do you think its worth?
It is set up like a XLCR w/ the tank and rear section.

Thanks chevelle, will you buy your friends bike?
It's hard to say what it would be worth over here, the market is strange where Harley's are concerned.
I'm hoping to get the engine bits vapour blasted this month so I'll keep you informed.
Cheers, Waffa1

I think I will buy it in the spring, I need to get my project back together. If I were to buy it now I would have too much fun playing w/ the new toy and the old toy would stay in a million pieces.

Anyway here is another Sputhe Sportster..... this ones got NOS!

Default NOS Sputhe

Many thanks for the link to the NOS Sputhe chevelle, I've managed to buy Easyriders mag # 108 from ebay usa.
The last email I got from bigbear was late on last year & he was telling me he was going to move to Arizona I think???
Maybe that's why he hasn't been on here?
I gave him all the fin dimensions from my heads & cylinders & also told him I'd had to have head gaskets made because the face to face surfaces were corroded, a guy your side called Lani ( advertises on ebay ) made them for me, lovely job. Keep you informed when I get things done.

Hi, I'm starting to get things going with the Sputhe but need some help please.
I was hoping to junk the generator & fit an alternator, I've been told that an alternator is available to buy, does this replace the generator in the original position or do you have to adapt the primary case to fit it?
Any help will be much appreciated.

There are a couple of ways that I know of. 1st check this one out on the forum - these are available from vtwin:
http://xlforum.net/vbportal/forums/s...d.php?t=599461
I believe these rotate externally.........and they're supposed to be available with an internal regulator.
There is another post here somewhere, and they've used a small automotive alternator with a machined adaptor, which gives a little more amperage. I'll try to dig it out
