Well, everythings as done as its going to get now. Did a dyno-run last week; the jetting in those SE carbs were surprisingly weak. Going from 165s to 185s still wasn't enough, and 185s were the biggest I had. We made a couple of pulls and got 100HP. Far from optimised. All down to the great white dyno now!

Did a short vid of it running (195 jets now):

Here it is ready for loading:


And with Shaun, who's coming along to crew:

Ready to roll. Off to the shippers first thing tomorrow along with the other guys:


Gotta be honest, I'll be glad to see the back of it for awhile!

Are you guys going to stay for the BUB Speed Trials August 25th? I certainly hope so 'cause you've got a fantastic build there.

Get off the stove Grandad.  You're too old to be riding the range.

Briz, thanks for sharing your build!  I have enjoyed the read and the corresponding history associated with the Weslake v-twin.  You have certainly created a bike that does that beautiful engine justice.  Congratulations and good luck!

Good job, Briz.  A hundred horsepower is not shabby.  We will be at BUB.

Thanks guys, its on its way now. See you all out on the salt.
Cant stay for BUB unfortunately, funds wont stretch that far I'm afraid; this has already cost more than the GDP of most 3rd world countries!

Well, we made it!
we're here at Bonneville; everything has worked out well so far.
The bikes arrived at LA OK, all the online booking of transport and accomodation has gone smoothly.
we arrived at wendover on wednesday and went out to the salt yesterday morning and got the pits setup:



After a little preparation, Desperate & I got the bikes into tech inspection; Mine passed and desperates Indian just needed a little lockwiring. Registration now completed and ready to do the rookie thing. tomorrow....assuming the salt dries out!
One screwup; I discovered that I'd badly miscalculated gear ratios. Turns out at max rpms it would theoretically be doing 270mph! Biggest rear sprocket on now, but top gear isnt going to be 5th!

Well, speed week is over, and we're leaving amazed, defeated and with many lessons learned.
This stuff is no cakewalk, as we discovered and as you all already knew!
We never got to grips with fuel supply and had much trouble with carb vibration.
Some makeshift rubber mounting of said carbs saw our best run on tuesday of 111mph. We typically ran out of power halfway up the first measured mile which indicates fuel starvation despite enough fuel  line capacity to run a big-block. Should have had a pump.
The bike itself proved to handle well and went straight.
Pretty sure we'll be back. Probably not next year but in 2014.
I'm kind of through trying to re-invent the wheel with this drivetrain and will be selling it on in favour of something with better parts & knowledge base, maybe a Buell XB9 lump or similar. The Weslake is a strong engine but its going to take a lot of time and testing to get the best from it. And this is not easy when you live on a different continent from the salt!
The  bike goes to the shippers in Los Angeles on Monday.
Anyone in the US who might want to make an offer on the drivetrain would need to act quick!!!!! :-D
