Quote from: senensis on May 22, 2016, 02:52:10 PMThanks for the old school 2 stroke effort Gave a (very) quick spin to the 125. I think it has way too much low end torque - it is too easy to make it flip in first and second gear without the clutch outside of the pipe range. In that regard the CR125 feels much closer to what it should be (even if a bit too tame).

When you do mx in a 125 you have to quick shift the gears up to get a decent speed. I must tweak that low-end. Thank you so much senensis for the feedback. That's what I need to improve that and next bikes.

This is at the rear wheel so for the engine I think you should add 20% approx (YZ is given at 31hp, was 36 factory I think). http://www.pulpmx.com/sites/default/files/u165/csteel101_10.jpghttps://gyazo.com/dcebdcd0f1dc65d6507504288f7840aaIt starts at 7k, but extrapolating from other data, you have a flat between ~5 and 6.5RPM at 10hp, then it goes down to 5hp in power at 4k RPM minimum and then stalls.

Quote from: HornetMaX on May 24, 2016, 09:54:17 AMHow much you lose between the engine (crankshaft) and the wheel is described (in MXB) by the "Efficiency" parameter in the "driveline" section of the bike .cfg file.For this mod bike it's currently set at 0.92 (i.e. you lose 8% power). 20% transmission loss sounds huge (for road bikes at least, don't know if it's any different for mx bikes).

Quote from: ChrisK on May 30, 2016, 08:40:38 PMthe engine now feels realy good but the autoshifting is bad it shifts maybe by 5000-7000rpm.ya i Need autoshift rider lean f/b r/l, dabbing, using the clutch, steering, throttle, rear brake front brake is enough for my fingers
