Actual motorcycle content....no....really!

Well.....more or less anyway.
So it's hotter than a whorehouse......it's hotter than a Jesus-freak on a....umm...well it's really friggin' hot outside the app on my spiffy phone says it's currently 98* outside and if i walk back into the shop it's....122*!!!!!!!!! So, as you might imagine, too hot to accomplish much past say....10am until around 8pm when it'll cool back down a wee bit. In the mean time I play with spare parts and plan for the other frame just like this one:
Sakura with the old Triumph short course tank and a random Sportster seat that actually REALLY works pretty well with just a touch of rework. I like the way this looks, screams Brands Hatch to me. I WILL build this version someday soon.....
Doesn't everyone use channel lock pliers to remove valves? Me neither.....In this case the owner wasn't worried about the shafts because........


....because I'ma gonna cut'm up on the lathe! Quick first pass.....

Here they are after a few passes on the lathe, a few more passes in my home made swirl polisher and now needing only to be lapped to the valve seats. For general edification: Thinned stems for more flow, blended the tulips for improved flow, back cut the intake valve faces for some small bit of anti-reversion and the hard to show radial seat blend. yeah...they'll flow a bit better than stock!

  1. HA! Thought you missed them, good to see you here Bob. I think they'll do the trick no?
    I should be able to get started on the head late this month or early next. I'm waiting on some parts for the flow bench and my silicone for port casting but all in good time. This WILL be a fire breather.....
