The road rocket racing sidecar project

[Rocket Racer]

G'day Tim.
Just make sure you short shift whenever you can to give the motor a rest. She won't like being at full boil ALL race. I have seen a lot of motors in pieces after a box change to more cogs.
Cheers

I hear what you're saying. My hope is that I can lower my hard red line into the mid sixes and keep the motor in the 5k to 6k range, whereas it has often ran through to and well beyond 7k which I haven't been happy with, but then it was also sometimes down in the 4's out of the power.
There is also some other development work in the winds which I will keep quiet until finished and hopefully realised as planned. But I'm hoping I can reduce load on the motor by being able to downshift less brutally.
I'm hoping to have it ready for testing by the spring (around September).

new pipes taking shape, but above top front engine mounts, both downtubes have broken so time for some repairs and careful review when engine and gearbox out.
It has taken a lot of abuse and not really what BSA designed these frames for

Love the gearbox, jealous as.   But would probably need a kicker for road use.

They say they're going to be doing kick start versions but I'd just fit electric start

[Rocket Racer]

They will fit a kickstart if you want one and at a modest charge, but on my race bike its plugged so didnt go down that route. They don't have a speedo drive,
They do splined or tapered mainshafts and the clusters are common to their other boxes.

With the motor on the boil more, I'm looking to retire the chronometric tach and fit something that will give real time information

I'm thinking about doing an HPC coating in black on the exhaust system rather than chrome this time so any castor oil marks dont show

[coater87]

 Here powdercoaters offer a ceramic coating for the inside of headers.

 There are a bunch of theories on why it's good for racing, but a lot of regular guys do it because the headers last longer I guess.

Hi RR

I would have been very tempted to go for the splined mainshaft option

If all goes to plan  the next race meeting is late August; engines stripped down, crank needs a grind and...
but hoping the streamlining will be completed sometime this week, the bikes rolling chassis in Carterton sans most bits
so a few things to do.

Carterton? In the wairarapa?

Carterton? In the wairarapa?

Simon, yes, about 14 hours return in the truck 
Probably heading down for a days outing in the next week, dropping it off I left at 5am and was home by about 8pm.
The very clever guy doing the work has one of Geoff Perry's bikes https://www.youtube.com/watch?v=h9He_3pX1_I

Hi Tim,
the fairing looks great
I have ordered last week my TTI 6speed for the A10.
Designed a stronger new barrel with a 3D programm for a 750 big bore conversion, seemed very expensiv to produced the mouldings.
Don,t know if spend this tousands of Euros for a mould and no one want these barrels.

cheers Klaus

Klaus,
your barrel plans sound like a thread on their own. I know I'd love a big bore alloy barrel, I guess interest always comes down to cost. http://www.shopevengineering.com/BSA-Alloy-A65-Cylinders-detail.htm?productId=-525795&browse=-35182%27A=0&shopby=-8415&catalogid=-2087 and whether if you could preconfirm enough interest to justify 10 or 20 barrels like the a65 owners have.

But given most my competitors are on 750-1000cc replica motors it would be nice to keep my a10 in the game.

Hi All,
A while ago Julian M built a big capacity A10, CNC machining the cylinder
https://www.a7a10.net/forum/index.php?topic=6024.0
I'm sure he did not throw away the CNC program 
As he is in the "trade" it would be worth contacting him

I have read about Jer Hill's A65 cylinders on britbike forum they seem to be the business 
Currently he is looking for orders to make another batch of 10, 5 speed A65 clusters but is having difficulties getting commitment 

Some years ago there was a move to remake cast iron A10 cylinders but the number of reject castings made the proposition uneconomic, as the foundry wanted to be paid even though the castings were unusable

Yes Sure, I would love an alloy cylinder for my A10

how much weight is that fairing gong to add Tim? looks rather large (and very cool)
