Glass fibre bits on.

Not sure about the air filter retaining bands though. May do something different there.

I used them years ago for road racing and was impressed with the set up service. They never gave any trouble, were the right price and still fitted to the bike when i sold it years later. At the time they were basically just copies of girlings, not sure what the off road ones perform like but they look the part on the 73 :ok

Speaking of looking the part, that ride looks like a show bike. :thumb

Don't worry Stan, it will be getting very dirty. Hopefully very soon.

Don't know who made Ian's but have a look at Raysons Exhausts. They are over your way and will make you a fantastic system. Ben and Tom are the guys there and will build it exactly as you want.

Have you tried Mark at CCM Britain

Or try OS Pipes
If you have a look at following link and click on CCM B50 you will see the the purpose made Exhaust in Stainless Steel made for my Bike.

My exhaust was made by Colin Hickie at Hickie Racing down here in Devon. I wanted a steel system to keep it the same as my other original CCM. I also felt that the chromed steel would be lighter than the stainless equivalent. It would have been a great deal cheaper to have had it made in stainless too !

Interesting 4 cylinder engined BSA at OS and the triple BSA certainly looks the Hurricane part - but I digress. The CCM looks great but what is the CCM header diameter?
1 3/4 ?
Also what wall thickness of the stainless tubing used?

I used to ride it in the late 70's early 80's on the road with the original straight through MX Exhaust, don't think I would get away with it today.

hi grouty, superb looking bike and ex pipe. as a rule of thumb st / steel is only about 0.5 % heavier than steel, so if the whole lot weighed 1 kg in steel, it would only be 5 grams more in st/st. a small price to pay for "last for ever"

That's true Stew. But the biggest issue we had was getting stainless in 18swg tube. Most stockists want to sell you 16swg or 14swg.

I am happy with the chromed system as it's 18swg. The pipe diameter is 1"5/8 (on the advice of Mark).

A little bit more done over the holiday period.
Forks stripped and re-assembled hopefully for the last time. Front brake arced to the drum, and cable fitted.

Image

I measured the travel at a perfect 6"1/2 . I have used 15wt oil to start with. We'll have to see how it feels when I get to ride it.

Image


Throttle and clutch cables done. A lovely pair of bar clamps made by Anita :smile:

Image


Rear brake cable and pedal.

Well spotted Gerry. I wasn't going to put the nyloc's on until I had finished taking the wheel on and off. Thought I would wait a day or two to see if there are any weeps from the fork slider first.

Bit of an update ......

Interspan trigger fitted, wired and timed. Several fiddley bits done that I won't bore you with. Filled it with oil on Friday (R40 of course !). Let it sit overnight.Saturday was leak free ! Fitted the fuel pipe and put some race fuel in. Fuel on, choke on, and a few kicks through to wet thing up a little.
Ignition on, and it fired up second kick :grin:
The next challenge is to sort the jetting a little. Choke off and engine stops, or touch the throttle and it stops. On Mark's advice I will try a bigger idle jet and see where that goes. These Dellorto's are all new to me.

So it looks like my 10 year build will soon be done. I wonder what will be next ?

Ok, it's been a while. But the weather had messed up my first race meeting, and the second, and the third I was clerk of the course so couldn't ride any way.
I got the chance to take it to a modern practice track today .....

So, I finally got to race it for the first time this Sunday. What a lovely bike ccmicon It started and ran faultlessly all day.
3 superb starts, and with all my years of experience, I slowly and carefully worked my way back :lol: Ended up with 6-7-6 results.

A huge thank you to Mark and Anita, without whom my dream would never have happened.
