Post by: pacopastor34 on May 13, 2016, 11:35:02 PM
UPDATE 24/05/2016

125 Engine updated by senensis.

New links from MXB-CENTRAL.COM!!


UPDATE 22/05/2016

125 Available to download. Link below.

Hi, here you are the first version of the '96 250 and 125 Kawsaki KX SR. I'm not a good modeler, just starting to learn. It's my second model ever. And my first in 3d Max.

I put very much love and time in that work. It wouldn't be possible without the help of the community. In special RiccoChicco, who gave me a lot of info in the beginning.

I took some parts from 250sx p2sta/attacker/ddmx old model.

Great job for your 2nd 3d model ever! Absolutely love it and will have some Axo Splitfire gear to contribute to the cause soon ;)

P.s.. For the next version: the front wheel is not in line with the forks.

For me the engine is perfect as well as the handling of the bike. It is very good going in and out of turns.
Really good job on these two bikes.

Cheers  ;D

Thanks 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). Expanding on this - it picks up outside of tight corners without the clutch way too well for a 125.

Edit: the 1st is a bit long, rest of the gears seem on point.

I'm agree with you, CR125 feels close to the 2stroke mid-range kick. But I wanted to recreate the full throttle 125 ride style. 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.

Added a quick edit as you replied.

I see what you mean, but that 125 full throttle style is usually achieved by going through clutches like a mofo :d It's all about reaching that mid range pipe kick asap and keeping it high revs to avoid the bogging down at low rpms. I don't know which power / torque curves you used, but I would suggest a slower ramping up at first, then a steeper curve reaching the mids.

I'm gonna tweak that engine in order to get that kick and fix 1st gear.

That's the curve I made.

This looks like a 250F power curve. For a 125, you are looking at almost nothing (10hp) until 6k RPM. Then it starts picking up. Have a look at this article:
http://www.motorcycle-usa.com/2002/11/article/2002-yamaha-yz125-vs-yz250f-2/
There is a power curve and a torque curve. It's for a '02 125YZ but quite frankly, nothing drastic has changed on MX 2 strokes engines since the addition of liquid cooling. The engine is basically empty until 7k RPM (most dyno you can find go down to 5-6k only, where you have that flat section of the power curve. Below is idle anyway).

This is a RM125 which were at the time known for requiring even higher RPMs: http://www.scalvinipipes.com/ScalviniDyno-RM125.html

I hope that helps. It's more difficult than I thought tracking down the proper dyno charts for those small smockers, but any year between 1990 and 2005 will be in the ballpark.

Ding ding ding!
1996 125 dyno chart. 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).

https://gyazo.com/dcebdcd0f1dc65d6507504288f7840aa
It 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.

Oh god, that is amazing. Thank you so much , I'm going to work with this  to make it the most accurate. I will contact you before the next releases! ;)

How 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).

Good catch, thanks for that. 20% is indeed high but given the different values you find and the first full dyno I found (first link, I don't know what they did with it), it matches when you multiply by 1.2. That's why I recommended bumping by 20%.

Still pretty exited by what's coming up next once we dig up more data and modders get a hang of things!

the 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 :D

Just do auto clutch with manual gear shift. by the way, manual transmission is much faster.

Man you should have bumped it - I didn't realize you had re-released it with the new engine files (senensis here, I changed forum name to stopped being confused with myself :d).
Enjoying it more and more, even favoring it over 4 stroke for SX now. The frame works well and it's fun to ride. I am a masochist like that.
