Some how the log book topic became a capacity discussion. Alan C. writes"Keith, I'd like to see a class introduced into historic racing, with a 750cc limit. The gap between 500cc and 1300cc is too large and really you need to have a bike around 1000cc to be competitive in P4 unlimited.
The 750cc Pushrod Class is good, but I don't really see why 750cc XS Yamahas, and genuine CB750s and Z750 Kawasakis shouldn't be included.Apparently they run a 750 four stroke class in NSW. I suggest we should try to get Australia wide formulas for historic racing."
Why have a push rod class event and then let CB750, XS750 and Z750 race in it, it defies logic? If those blokes want to race they can in Formula 750 which is a national class. At least the push rods are turning up which is more than the others I have listed are doing, so why wreck a good event?
Anyway, CB750's make good sidecar donks and XS 750 are good as boat anchors, I cant think of a use for a Z750.

Just raising the point for discussion, John. Just repeating what I was told about the 750 class in NSW. The factor which has eliminated 750 pushrod machines from P4 seems to have been the presence of much larger machines in every one of their races. If you think back to when Tony Cacciotti rode the Bill Patterson CR750, you'll remember the main opposition was Peter Allen on the Mussett Triumphs, a Bonneville 730, and a 750 Trident, and he usually beat Tony. When Don Emde was here on the XR750 Harley, he was right on the pace during practice, but ran a timing side bearing during the actual races on the Saturday at Calder. There was no standard CB750 Honda my 500cc Triumph couldn't beat. I held off John Collins on it at Calder one day when he and another guy had the Mussettt Triumphs there, at a Hartwell Club day.
Simply imposing a 750cc limit on a Formula 750 Class, and excluding two strokes, would bring back a lot of competition into our sport! The problem with the pushrod class is that it is run concurrently with the unlimited at some meetings. It's all very well to have a trophy for a class winner, but there's nothing like being first over the line, if you're the winner. We either need more 750 pushrod machines or widen the class to include certain OHC bikes - enough to run a field of class eligible machines.
I know I might be jumping the gun a bit, it's early days for the 750 pushrod class. The pushy class is a bloody good idea - let's work on it? |

| I think Don Emde was here in 1971. |

I am glad you like the push rod concept. We DO NEED to get them fronting to justify a separate event. By the way have you thought of a use for the Z750!!!.
Formula 750 will cover stock machines, and they also need to tun up. |

A Z750, if you could find one, would give a CB750 a real hard time, and could probably be made to go a bit harder than a CR750. I just couldn't think of any other 70s Jap OHC 750, which could race in a Formula 750 race. Later on there were 750 Katanas, and GS750s. There were XS750 Yamahas. Actually Greg Lawn of Central Motorcycles pointed out a few years ago, that old Japanese 750s were pretty cheap. I don't think they'd be that easy to find these days.
The point is a good 750 Bonny, Atlas or commando will blast off most of those old Jap 750 four strokes. They will also beat most 750 Ducatis, but a good 750SFC laverda can be very quick. If you think back to the Jim Eade Laverda of 1973, ridden by Vic Vasella at Phillip Island - blew off Hone and Decker on Z900s.
If someone wanted to get a Z750 going fast, it would mean meggas, fairings, and hot cams, and they wouldn't be allowed to use alcohol. |

| OK but at the moment the HMRAV does not want them in the push rod events. |

I don't blame you for that, however how do we get the word around that Bonnies, Atlases and Commandos are getting a new deal? Do we need a bit of promotion/publicity. Perhaps an article in the AMCN might help?
Are we running seperate events for the 750 pushies this year? |

Seriously John, I've been unable to figure out which way to go with the 850 Norton. Do I build a quick short stroke Norton 750, or do I send overseas and buy a 750 Weslake motor? (Both would cost about $3000) An alternative would be to build a 500 and wait for InCA to come here - FAT CHANCE!
If the 750 pushy class really gets going, it'll be worth investing a bit of money and time in building something a bit decent. |

| I am happy to help attract pushies to an event. At the moment I do not have the support for a separate race, mainly because everybody wants a separate race and we dont have many pushrods anyway. Maybe over this year we shall get a better action plan happenning. But for the time being, we need to get them at the track. As for what to do with yours,Al, get a sidecar. |

How about a separate Formula 750 race with a trophy for pushrod 750s ? (NO TWO STROKES) And run a separate series for the two strokes (I really liked the two stroke races at Broadford the other weekend)?
The events could be 'ACROSS PERIOD'as long as every machine was eligible for one of the listed periods.
This would reduce the total number of events to be run at a meeting. |
