Hi again,
I am also planning to do a little frame bracing; maybe only a couple of extra down posts (near battery box) and mig welding the dodgy stamp welds on the bike.
Does anyone have any hints on how crazy you can go with additional bracing?
Cheers and Thanks,
Ben.

I have obtained this answer;
Frame bracing comes under the catergory of period modifications. You must be able to prove that such bracing (in this case) was actually done in the period. Minor 're-welding' would probably be permissable but it would need to be on a individual case by case. The extra down posts would definately have to be a proven period modification. So the main hint would be not to go crazy.

Ben,
I have a fairly extensive collection of CB350/CYB350 photo's and writings, the clean up and boxing in of all pressed and spot welded sections is common to all CYB and most CB frames of the period, boxing in or bracing the frame just above the swingarm is done by most American racers in the class but may need to be confirmed here.
E-mail me at gorcat@bigpond.com and I'll send you as much as I have in dribs and drabs (dialup takes forever) or burn it to CD and mail it (I have been collecting for quite a while so there is a fair bit including some choice webb addresses).
did you get it running?????????????

Hi Ben
Do yourself a favour & look at some/most of Honda 4s down you way at the next meeting!! they are all braced, extra frame rails, gussets, filled in whole sections with sheet metal,etc etc If people are going to jack up about period mods to weather they fit/or were done back in the period half the field if not more in period 4 would be in trouble also!! But saying all that a nice pyramid shaped brace above swingarm pivot below seat base helps things greatly best of luck with the project, I will go out & race it 1st & change things as you go, Race with the seat of your pants!! is fun!! Waiting to buy, getting the best parts the right gearing tyres etc etc Turns into armchair racing!! which is boring!! It seems like armchair racing is overtaking actual racing lately, so get out & have fun Ben

| the Vic. HMChas been approached to discuss a push from the MA board to consider the future of Historic Racing and the guidelines. In the short term please dont put new technology into your bike at the moment until this issue is discussed. Steve was correct, many bikes may not be kosher with a new interpretation of the rules. I shall keep everybody informed when things start to move. |

Ben, If you want to get some advantage, have a look around for a Seeley Honda frame. There were a lot made by Colin Seeley in the seventies, and some came to Australia. I believe the Dunster Bros from Canberra had one a couple of years back, and you might be able to track it down.
Please be careful doing frame mods, if you change the head angle, make sure you get the fork offset correct, otherwise you can crash easily. |
Is your machine authentic or merely eligible? |

| Alan, surely mods to a CB750 in the period cannot be interpreted as permissible mods to a CB350 in 2004 if new guidelines are introduced. |

Heya,
Thanks for all the info, very helpful indeed. Steve, Mick, I am just a little worried about racing on a bike that I don't trust! I want to get it to a state where I am comfortable with it and it is in the best possible state (given time and money)before endangering myself and others on the track! I am not trying to be an armchair racer, I'm just new is all! Don't worry, I'll be out there soon enough!
Cheers,
Ben.

| Advice I have received from most of the AHMRA blokes has been to do your first season or so on a close to stock setup and work up from there, the reason being that crashes and mechanical isues from learning racecraft and the capabilities of your machine become very expensive if you have already modded it to the max. This is one of the reasons I am starting with the P5 CB360 and wont build and compete on the 350 until I have learned how to race, I dont really mind if I am doing it from the back of the field on an uncompetitive bike because the skills will be up to the full on machine when it is built. |

Hi All
Ben the 1st time I raced (some time ago on the road) I rode the bike their took off the lights & the pipes & left just the headers & turned the handle bars upside down chucked some race number plates & went racing had a ball finished down the back somewhere, & then put on lights & rode home!! & started changing things to make it better to "race" it all started their & after I race now I always change something for next time to improve things (I hope or wish) at thatI had some fellow come up to me & say it wasn't period (P4) So a bit disheartened went & had a look at his bike which was so called period look, just about every part was changed from say standard to the best bits from many a bike/s forks were different swingarm, frame mods, wide rims to double dics on the front etc etc etc & even a late model out of period engine!! & he's telling me thats my standard bike from the factory minus lights & rego plates wasn't period yea right!! I run still today!! drum brakes all around (which looks period well I think!!) double brembo's 38mm -40mm forks late model carbs "don't look period to me anyhow (P4) Period 5 yes!! but don't look right to me & lots of spectators think the same way also!! maybe I'm old fashioned but when my father 70odd tells me they didn't look like that when he was hanging around the tracks years ago is good enough for me, funny one day this fellow came up to me & said he could hear the scream from the my drum brakes as I out braked him coming into a corner in SA, I didn't have the nerve to tell him it was coming from my helmet & not the brakes, but Ben it all about having a go, thinking back now it was a bit silly, but I'm still as silly as ever & yes having fun also.

Hey Steve,
Yeah, you are right, its all about getting out there and having fun. It will still be a little while before I'm finished the bike to a safe and reliable level....... without going tooooooo over the top! I look forward to seeing all your backs then, or maybe I'll be to far behind even for that! I suspect even losing will bring a smile to my face.
Cheers,
Ben.

You might be looking at their backs, but put a mirror on so you can read my stickers as I struggle to keep in touch , and my machine is P5 |
