lets just say i am happy i got the lower air filter and silencer out of the way before the leak

 

 

This is really cool! I have an 2018 KLX250 EFI. I will definitely check this out when I do my valve adjustments! I'm currently at about 3700 miles on it. So I still got a little ways to go. But this seems really interesting thanks for sharing!

 

Goos, you will feel it when you are on a really steep rough trail and find yourself coming to an almost stop in 2nd gear about to lose it, instead of stalling and falling you open the throttle and the bike will just react and drag you up. It is that low down torque that MCM gives you.

 

@Klxster @klx678 guys bit the bullet after 4 years and doing MCM after I put the big bore on.
Issue is I ripped the top off , got it to TDC and it looks like to me at some stage the bike got a 1/2 MCM exhaust only.
Looking to see if my assessment is correct?
As above took me 4 years and lots of reading and studying @Klxster pdf. diagram looking to see if I am reading this correctly and all I have to do is the Inlet side?
Based on everything I have read here why would anyone just do the exhaust. When I got the bike it had a standard header with DG slip on?
Cheers Geo.

I see a 1/2 MCM Exhaust side, am I seeing this correctly, at TDC Mark in the gap.

I am seeing a 1/2 MCM exhaust side.

 

I does look like some moron did-up a exhaust retime and left the intake stock.

What did this moron do with the KACR ? Pull the spring ?

 

Thanks for the response @Klxster . TBH, this I guess is the surprise/ adventure, call it whatever when buying a bike that is preowned. I know I am at least the third owner. The KACR will go down and take a photo, but the spring is still on.
Also thanks for the confirmation I feel a bit more sure in moving forward and where i will mark the sprockets and chain for reassemble.
1 thing I notice if I full throttle it on the highway/ back roads when I have it in supermoto mode, it's like it starves/ pauses for a think at about 6k RPM. Haven't pulled the jets yet on the CVK. Though thinking of going the Mikuni, whilst I am at it.
Appreciate your support.
Thanks
Geo.

 

The chain placement is irrelevant. What you need to pay attention to is the T mark on the flywheel (top dead center), that the cam sprockets are bolted on with the exhaust in the IN holes (as it appears they are) and the intake sprocket bolted on in the EX and the cam timing marks (which it isn't), then at that point, the cams should be placed with the alignment marks to the inside of the cam run positioned two teeth above the surface of the heat (which the exhaust is). It appears whoever did the work didn't do the intake cam, only the exhaust..

Here is what it should be. The chain is "endless", so it really doesn't matter how it is put on the cam, just the alignments of the marks are important.

 

Went down this morning this is the view of the KACR still at TDC. of the Exhaust 1/2 MCM.
Start OK when warm
Have to lay it on its side, choke out when cold to get it started.

Thanks got it.
