heres the initial results of some of the 05 bikes

The 05 cr125 isnt good(surprise) the rm is good but still has the pv opening to late, the 05 husky engine could be great but has serious pipe and pv issues(same for last 100 years)

the rm is in red
the cr is blue
the husky is green(wavey line)
the 05 yz was better than all of them(looking for the dyno)
the 05 kx was a good engine with not a great peak but wide power(didnt graph it, as it had a knobbly tire)

Ohh and the 05 crf killed them all dead as a dodo :think:

33hp and loads of bottom mid and lots of rev-i stopped at 13000rpm but the limiter didnt kick in.

If you ever found it I would like to see the 2005 YZ 125 dyno.
Just to see what I am working with and to be able to spit out some technical info on bike if need be.

The husky is the most surprising dyno for me, with just a pipe it nearly fixes the dips etc and then its a super stong engine,as strong as any out there IMO-maybe stronger.

I brought all the dynos back from Kps but had the 05 crf on the dyno at the time, so it didnt copy the runs over :( i know kp showed me the 05 yz dynos but he said he was in a rush and put them in a older YZ folder, and i dont know which ones they are or if they copied correctly.

The 05 KTM is basically a 04 ktm and they were all strong midrange-not much rev at all.Kp has only tuned about 3 KTM 125s EVER-people just dont tend to have to bring them in, a pipe and a few other bits is enough for most riders.


The cr125 is the main 125 for tuning, i was going to do a dyno chart of all the crs from 01 to 05 but the graph gets a bit cluttered.

Your in luck steve has built a 05 yz144-lets hear how it goes steve?? im guessing its not that different to the previous yz144s, i say this as the 05 yz dyno is good but nothing amazing-a nice engine but for all the changes its not much different in power to a 04.

The 125 yz is a good engine but not amazing good-steve says the 144 goes better than the 03 yz144 but i still think its a little behind a crf250 but it would be alot closer than most 125s. I dont think you will lack power on the 250f as it has a good engine this year.
