If it is a A10 it will be a 650cc Twin GOLD FLASH or ROAD ROCKET.

Gold star are singles

Some info on the BSA Rocket Gold Star here, http://en.wikipedia.org/wiki/BSA_Rocket_Gold_Star .  A mate of mine owns and rides one on the road. Also :-

"All Rocket Gold Stars have the frame number prefixed with GA10 except for the first two test machines. The first one which was dispatched on 31st January 1962 with frame number GA7.12925 was fitted with engine number A10R.6380.  Production began in February 1962 and the first bike, frame number GA10 101 was dispatched to BSA New Jersey on 16th February 1962.  It was finished in red. There were 1584 bikes made of which 272 were scramblers."  (Excerpt from Brian Pollitt article BSA Owners Club)

They are my favourite BSA model, except for the unit Spitfires. Martian, as it's a '58 model, you may have a Gold Flash, iron or alloy head ?

Great to read about another BSA being built for scrambles. Hope you have fun with it. The good news is, they are a pretty simple engine to work on.
Pay close attention to cam timing as this where most power can be lost or gained on any of the old pushrod pommie motors.
Yes, the rules are the same regarding travel limits for suspension. The forks will need to be of the period. There are a couple of choices for the good forks. Ceriani's, Betor or Roadholder's are the gun forks for the era. Personally, I think the ceriani's are over priced for what you get. I have Roadholder's on my B44.

Pretty sure that betor's and ceriani's are for pre 64 not pre 60?
Anyone got documentation proving otherwise?
Cheers. DJ

Yep, 7 and 4 is the go, but before you get started on the bike have a look on the www.ma.org.au site, read through the Manual of Motorcycle Sport, particularly chapter 16 for classic mx rules, and 16:15.7 for pre-60 rules. No point knocking something up, then finding out it's not compliant. There are several threads on this forum based on little else, and there's a long history of people turning up with bikes outside the rules who have left cursing and not returned.
Should be a good weapon though Martin, a big twin sounds great in a vmx field. Best of luck with your build.

For used parts - Murrays brit bikes/brit spares (not sure of exact name, lists in Just Bikes magazine) http://kmmotorcycles.com/frame.html

Good places i use often and recommend which will have what you want are

www.classicallparts.com.au
https://www.draganfly.co.uk
http://www.burtonbikebits.net/
www.feked.com
http://www.vintage-motorcycle.com/
http://modakmotorcycles.com.au/ (have not use for years)
http://burlen.co.uk/
http://surreycycles.com/
www.davelindsley.co.uk/



And british spares in NZ is gonna have a lot of what you need too (address in my earlier post)

I looked through your list and all those parts are going to be available

Start with British spares in NZ and Draganfly in UK first. They are the best. Then go to the others for what they don't have.
Title: Re: A10 gold star parts and advice
Post by: martian170 on February 07, 2015, 05:15:20 pm
Awesome thanks for that will start working though the list
Do I need a steering damper ie something a got to have or just road use
Only thing I have not found is the ht lead pick ups but shops / stores may may these ( hopefully)

Well project sort a finished achieved 9 laps at the last narrogin meet went really well after Peter lawson told me it was only running on one cylinder. Gradually built up speed but the gear change and brake on wrong sides where scary, things to do make more decent foot pegs and swap over rear brake and gears other than that ready for wondering then the Nationals thanks to all for help advice and support , most improved modern modification has to be the bright spark magneto condenser worked a treat
Ps if Ya in my race you may need ear muffs whilst overtaking the girls a tad loud

Yes Mick I know. I piked it. The A65 broke my spirit I am afraid BUT my Pre65 Bully is a great bike and the A65 will come to the track when finished by another Heaven member.

Congrates on a great build Martian170, looks sweet.

MOMS requires a silencer but that has not been universally applied at nationals in the past it seems
Title: Re: A10 gold star parts and advice
Post by: Brian Watson on August 05, 2015, 12:59:07 pm
Hey Martin, at recent nationals.. the requiremnet to have a silencer has been enforced.. I believe tho..if it looks like you have made an attempt.. all good.. even if the actual "silencing" was minimal...I know Gosta Lindgren was running around fitting a silencer to his BSA at Pt Augusta last year on Friday arvo..as Nick would say.. "aural splendor'..

The guy who races a A65 over here in NZ has genuine Ascot pipes on his bike, the pipes look straight through until you look closely & discover they have some form of insert inside the pipes which definitely work. He reckons there is no shortage of power & from what I've seen it appears it's easier to keep the noise down on a big twin than a single
