And the good news is that GPR010 has been started (& GPR011 is on the drawing board); come on Billy this must mean we can get Homologation for GPR frames and I can ride my twosmoker 250 in superlites??

Good stuff. Perfect time to remind scott I get a ride on the 550 when its track ready.

I have a sickness. Just purchased another 250 2 stroke. This time a honda. Oh and your knock gauge is here.

CR250? Sweet! - trail season is starting again.

Flywheel weight & soften it up a bit should be the biz,

Good idea. Next on the list. No this is a nsr mc18 with a 21 or 28 engine in it. Just so happens I have a 21 frame and swing arm in the shed. But will leave it Alone till the rgv is finished.

Hand up for crash test dummy

I guess the thing to remember is that 550 is the size of the bucket (read RS125) and is smaller than the only tig-craft in NZ. So it's going to be very very cool.

So bucket racing & tinkering (frames suspension engines and fueling) has improved our understanding and enabled some big gains on larger bikes; which should be on show at a track near you very soon.

Been reading up heaps on fuel injection systems to get a handle on oxygen sensors and A/F and mapping. Looking forward to playing some more.

Yeah a bit sick, mate of mine was moving to Australia and had painted all the parts off the bike, sold it to me still partially dismantled, we just put it together and flicked it off. Could have done with a repaint, but that's the new owners problem now.

Old video of Crazyman at Kaitoke, probably last year, riders might remember the occasion.

Who are those masked burglars at the end....?

I am real keen on getting on with my fuel injection project too but have been distracted by Team efforts to get two or three F5 2T's track ready. Had two of them on the dyno recently with disappointing results so far. But things could get better as Chambers has come up with a way of making a single exhaust port that is 75% wide and has a perfectly flat/straight top timing edge for ultra abrupt exhaust port opening. Anyway hope to test that idea on the dyno next week, then if it works out OK I can get back onto setting up the Beasts EFI. Bert please post some more about your EFI project.

Our current project is sorting out master boasters GPR550 v2. A shitty software platform called tuneboy connected up to the stock ECU; crashes continusily. but none the less it makes since and once oxygen sensors are sorted we should be seeing some dyno results.

Now stumbled across this, Great read (if you can read Italian then use google translate).. Right up your ally Husa.
