Nah done within a couple of weeks & no changes. Actually I'd have to look up my notes, but I think I increased power whilst doing testing on the Motomart dyno, so I last tested with 19 on the DJ & arrived with no changes & read 22 or 23
& got it up to 24 with some changes. So the diff may be less than I suggested, But you see what I mean. I had heard MM dyno was 15% optimistic by the DJ operators other comparisons.
Don't you look at my accountant.
He's the only one I've got.
See the thing is. If you look on line and research dyno dynamics v dyno jets all you will find is the opposite to what you are saying. All that aside I am very confident that the power the bike has is very close to what the graph is saying. It has a year of racing under its belt against fast CBR's and lots of street stocks on Manfeild and Ruapuna there is video even. You can not deny race results. The last all in race at BOB is proof enough. The bike is fast. And lets not forget with me on it the total weight is 200kg
Anyway you are not allowed to bag it, coz it might be for sale after Taupo. I need top dollar.

It is looking to be a very interesting year at the TRRS, and I will be there..........![]()
Hey I'm not saying it isn't fast. Having a flat power curve means the mean power through the gears is high compared to a peaky bike so you can go faster esp on longer ccts. My 125 was getting juiced by the RG150s at Taupo back in 06/07 but I beat them all 'cause it took them till the end of the straight to catch up again. Heck I beat a few RG150s at Taupo & Ruapuna on my 50.
Ruapuna takes quite some time to learn & those local lads sure know how to ride there well. But most of those bikes aren't fast.
Stay on at Taupo this year & I'm sure you'll do very well.

The power spread is a big thing, but a bit less so at somewhere like Taupo. We did a through the gears run on the dyno before we got it all sorted and it never went below 25hp after the shift. The MB50 gearbox is sweet but even so it was noticeable the drop in power between gears on the kart track if I shifted a bit early. Mind you it was only making 25hp then whereas it doesn't drop below that now when shifting on the dyno.
Some interesting FXR dyno charts.
A mid field or better FXR thats peddled with a great deal of determination and does very well.
NedKellys GP125 graph compaired to the FXR and you can see the FXR has nearly twice the useable power delivery and that seems to make them very hard to beat with hp alone at Mt Welly.
A megaphone equiped FXR that runs at the sharp end of A grade at Mt Welly. A little megaphoneits just befor 8K that the owner hopes to dial out with a different length inlet trumpet.
And Marshangs very well developed and interesting FXR special ...........
Speedpro's MB100 green line looks like it has plenty of useable power compared to TeeZee's GP125 red line and the front running FXR, blue line.
Its obvious that some hp is needed at Mt Welly but its the whole package that's important and the FXR's seem to have it as they are very hard to beat or even keep up with when racing them there.
Is it correct that the last three roadrace spectaculars have been won b FXRs?
If so I guess that would make them hard to beat at Taupo too!
