1999 cr 125

What should I run premix wise using klotz techniplate synthetic? I run 32:1 but have been reading its different with synthetic?

I run 32:1 in my 99 cr125 with Honda HP2. no issues in many years.

does your bike blow any spooge? i was thinking about going down to 40:1 because of how much i have?

Mine has a small amount when my wife rides it but none when I do. Change your jetting, not your oil mixture to reduce spooge.

well i also ride the woods and cant always go to fast but i normally stay and second and third sometimes but normally second so i can use the power and what should my jetting be in central pa? with an fmf fatty and powercore 2 shorty and v force 3 reeds

I wish I could help you with that. I am running a jd custom needle in mine so what I'm running won't help much. If its only a little spooge and the bike is running well I would just leave it as is.

well its enough that the swingarm shows black and well enough but i havent washed it yet and its only very small amounts not even enough to see come out the pipe up close but need a paper towel to watch it come out very little so i figured since its only a small amount moving down to 40:1 wouldnt be a bad idea im gonna clean it up tonight a little and might put up pictures for everyone since it is a very nice bike in my opinion

The type of fuel/oil, jetting and speed you ride has more to do with the spooge than the oil ratio. If you are riding trails, there are better oils than Klotz, that will reduce the spooge.

I would recommend staying at 32:1, with an injector compatible oil like Lucas, and reduce the jets to Pro Circuit specs.

so go down one size? and we have a big jug of klotz from when my dad had a 250

I revised my post to show PC jetting specs. They went down on all the jets w/ the '99 CR125. This will help reduce the spooge.

1369L needle @ 3rd clip

I was running klotz R50 in my yz250 with no issues at the mx track. But trail riding it was "spoogey".

I found out that Klotz has a very high flashpoint and needs to be run wfo. Great oil and great protection but not ideal for trails.

I've switched back to semi-synthetic Yamalube 2-r. I can also reccomend Super-M.

Keep the premix at 32:1 but maybe go up a clip position on the needle.

so it comes from the factory rich?

so it comes from the factory rich?

Apparently, very rich.

well alright that makes sense than about the koltz

why would it come that rich?

why would it come that rich?

To keep people from blowing up their bikes.

that makes sense is that how all 2 strokes are?

CamP that needles for a cr5?
