Dave Diprose had the Auckland champs pretty well sewn up with one for years. He won plenty of races. As always it's not always just the bike but the rider as well, hence my one never doing too well. There was a pretty fast one fitted in a RS125 chassis down south that from all accounts was fast as well though I'm not sure of actual results - Darryl Cotton's one.

DCs is an aircooled 125 with 24mm carb. believe it is someway short of 125. When DD bored a cylinder it went through to ally in some sections so full 125 wouldn't be possible without stroking it.

Funny though you say 6 speed MB100 though J, a 4 speed MB won the F4 GP a way back in ~ 1990 at Ohakea. It was protested but legal. I used much of the same engine in my H100 for a BOB attempt (but with 6 speed) & lead for most of the race until the big end called time 5 min from the end. This was just prior to FXR era, they would have nailed me, the poor H was winding itself up in knots & I couldn't take the kink in the back straight flat out & the hard old 18" slick was sliding into the hairpin every lap (been resurfaced since).

I also remember Mike on his RG framed MB giving Jimmy the hurry up at Taupo. It was visibly faster than the Kawasaki.

.

My Notes have Darryl Cotton and Neil Batchelor both with H100's?? 2nd and 3rd in the GP at the last TRRS and 1st and 2nd race 6 and 1st and 3rd race 14.

Dave D has posted a more complete and no doubt more accurate set of results from the TRRS some where earlier.

OK ok,..... and yes, it was an FXR (Andrew A) that won the GP...............and yes, the Suzuki GP's of Team ESE had to eat humble pie............

But it was certainly a day of "what might have been". Nigel Duff won the 1st 4 lap heat of the F4 GP before the red flag, & then seized on the 1st lap of the 2nd heat (the one that mattered). And I have to say that my son Nathanael qualified on pole 2.7 sec faster than any other rider, but then unfortunately broke the ring & gouged the bore on the 1st lap of the GP. He carried on for a few laps with no compression & no power, dropping back through the field. Then he had to go out on the 50 for the 2 races later in the day, managing to lap faster than most of the F4 bikes. I hope he has better luck next year. It would have been nice to see the 1st ever double bucket GP winner (dreams are free)...

Diesels MB possibly produces more power but has to carry twice the weight.....and is less reliable. The CBR's down here are the yard stick but there is some interesting projects underway to stop their domination. Both the CBR's down here are Aussie spec race bikes that are now modified (cams etc) and are ridden well by skinny arsed young punks. Last BOB Hoogie matched Avalons pace on a CBR (commuter frame) where as Avalon was on a RS125 frame. Watch this space!

. . . .and hopefully better looking.

That pretty well answers the MB100 performance question. The GP at Taupo where me and Jim came 1st and 2nd I don't think there was too much in it as far as speed went, mine may have been a little faster I really don't know. What I do know is that Jim's Kawasaki handled heaps better than the MB/RG. This was confirmed at a 2hr race some other year when I co-rode his Kawasaki. It proved the suspicion I had that Jim was just messing with me to make it look good for the spectators. Pretty sure we lapped 3rd place. Bit like me and Ziffle at the last Wigram GP, though I managed to be in front of Ziffle at the end of that race.

Sorry I spoke.

Making progress with the 50. As the stroke is 3mm shorter the cylinder had to be trimmed top and bottom to get the port timing where I wanted it.

The exhaust stub holes were stripped out and in the wrong place so I tapped them M8 and glued some threaded alloy plugs in with Devcon F.

When it came time to re-tap the holes M6 I found that the old welded repairs had moved the centres way off so the plugs did a great job of allowing me to get the new bolt holes in the right place.

I am very pleased with the finished job………
