At first I liked the finish of sandblast on the aluminum frame
But once I started arming, stop liking. To give brightness a simple and fast way, I choosed to use Cif and kitchen sponge, getting a satisfactory finish in my opinion.

A lack of tools.
With a rod and two pieces of valve, made a specialized tool Wink

I recognize that the clamps do not look very nice.

I have been reading in various forums and internet, information about of the original CR carb, the mikuni.
There is much talk that it is a carb very difficult to configure and somewhat unstable, so recommend the Keihin. Based on this and when riding the bike, it was impossible carburizing for me

So, some time ago, I decided to buy this carburetor Keihin PJ 38 mm from CR 250 1997.

When it checked, had neither the spring nor the needle, and as seen in the photos was pretty dirty.











Bought the repair kit and buy the original needle

Now, I ask this question
I am currently at 1200 ft above sea level... What settings should I use?
Which Power Jet, Jet Maint, etc.

I hope you please help me.
I just found your thread - great work!

Here's my carburetion i use over here in Switzerland. We are at about the same sealevel but my bikes have the older HPP engines with Mugen kits so it might still differ slightly. My carburetion is based around a very special sized needle which makes for massive gains. I have friends in Italy who tried it too and they couldn't believe how well it worked.

PJ 38:

Main jet: 190 (Using a stock cylinder you might try 185-188-190)
Slow jet: 58
Valve: 60 (By the way: yor valve is very,very worn. The only problem is that it might get stuck wide open....so take care!)
Needle: BGK (3./middle)
Air: 2 turns out
