HP is in the Heads, Revisited

At the time I posted about these cylinder heads there was some interest in what the power output was going to be. I was waiting for the tins to come back from paint, but I finally got the bike on the roller awhile back.

 

 

Ported the heads for the 95" listed below.

Every set I do is by hand & tailored to the combination.

No CNC, hogged out, everyone gets the same thing, cookie cutter, polished to the max, oversprung, high lift gains only, unknown chamber size combinations here.

All pretty basic mild stuff but with a lot of tricks for this engine.

I dont know if I would want to do a set every day, but it is kind of fun to watch them take shape, go home at the end of the day with dirty hands & aluminum chips in your pockets.

In anticipation for when it goes on the dyno & makes good power.

 

 

 I'm fairly happy with the outcome, although it could have been better if some other things in the combination were different. The exhaust isn't ideal, but it's what the guy had & he likes that look/sound. I left the compression really mild (9.5:1) so there may have been a little more there too.

Either way, its going to run real nice!

 The guy is 72 years old & this is his little bar bike/chopper. You can see what it makes over a 88" with air cleaner, exhaust & tuner.  Also what it would make on a DynoJet if you're all about racing dyno numbers.



Next stop!

It's all in the heads. Just need some valves to throw in there and I can show the kids how its done. Where'd I put my radiused inlet???

When Sportsters Ruled the Streets...

 

A friend of mine was telling me that he traded in his panhead chopper for a sportster in '64, paid $1000 to boot. 

He gave a me a book & I found this inside.

 I'll get the picture to him, but I doubt he'll ever get the bikes back.

Redirection

This time we're taking a bi-plane detour. The seniors are so engaged in this project.

WTF

Ever seen this in a locker? I'm tearing up a spare locker to gather some sheet metal in hopes that I can practice my welding for when I decide to patch up the rusties in my toyota. It takes patience to not warp the SOB and the Toyota metal doesn't like to weld for shit.

Dreamin' Of Reamin'

 

It's been a slow process but I'm finally picking up steam on my truck engine. I've got the port work mostly done, so it was time to install the guides. I made this little "bottle-jack gizmo" that sits in the lifter bore so when you drive the guide in they all stop at the same height. It went really smooth & now I'm dreamin of reamin!

I need NOS, Harry!

Two of the BIG ONES!!
