Stock 1993 Cr250 Carb??

Came stock with a Keihin PJ? But you can get a brand new in the bag Keihin PWK Airstriker from Service Honda for under $200 (look for the fische for 2000 CR250). The best carb by general consensus ever made for a dirt bike: easy to tune, keeps the tune, not as sensitive to air and temp changes, better response and better mileage. Every Honda I've owned I've switched over, and switched over my '96 RMX250 (BIG difference) and other bikes. You can probably get a used '93 Keihin for the bike fairly cheap but the price difference is worth it IMHO, especially given the seasonal swings in weather in Texas.

I believe Honda East in Toledo has that PWK AS for $180, I was looking at it last week. Going to get one myself, actually. Seems to me I have a PJ on the bike now, my 96 has that same carb too.

>ill order the pwk. Is it pretty much plug and play?

The 2000 CR250 is. Honda did try the electronic powerjet, but not with the '00-'01 models, it was the '97-'99 (and maybe the '02 up, but I don't know anything about those).

The '01 had a Mikuni that is fairly notorious for being tough to jet properly.

The 2000 came stock with exactly the carb you need, a PWK Airstriker. You may need to tinker with the jetting to get it set for your bike (or you may not, every bike is different), but the PWK is so ubiquitous, jets are no problem. You could just order the stock jets for the '93 PJ, they'll bolt right in (one of the other advantages of Keihin carbs-- they reuse the jets even when they go to a newer carb design).

When I swapped the '00 PWK on my '93, it was a direct, take the PJ out and insert the PWK, deal. I changed the reed block from stock to a VForce 3 while I was there, so I had to adjust the jetting.

>I was thinking of getting the vforce 3 also while everything is apart. Did you notice a difference with it?

I've ridden bone stock and VForce back-to-back on the same day and haven't noticed any difference. I'm talking about on my '93. If the motor is ported and case matched, then the VForce would give you more an improvement maybe. I have a ported, matched, etc motor in my '95 and yeah, the VForce helped it flow, but that bike is an animal.

The basic motor is excellent stock. Only a late model KTM is going to beat you. And the motor is close to bulletproof, too.

To get more power out of them, you need to do the whole enchilada, and then you have to run race gas. Keep it stock, it'll even run fine on 92 Octane pump gas.

It was the same for me, too. I'd run the 47mm Showa TC front end, and a 96 shock is a lot more advanced than the stock 93 shock. You're one of the guys doing the TC fork conversion, right?

Plenty of older pictures here with the swap:

Look up the thred here on "1996 MCGrath CR250" there is a complete discussion of the swap (and any other technical questions related to it you may have).

I just got a PWK from a KX250, likely a 98. Does anyone know if that is different from the 00 CR?

I think that carb has a top held on with 2 screws, and might also have a power valve solenoid on it. Unfortunately, it's about 75mm long, while the one you want has a screw top, no solenoid, and is about 90mm long.

The one I have has a screw top, well I will have to measure it. No solenoid as far as I can see.

>The one I have has a screw top, well I will have to measure it. No solenoid as far as I can see.

I'm almost 100% the '98 KX250s had an electronic powerjet. The solenoid may be missing, after all the seller just sold the carb?

>I have a 2001 cr250 and I put a 2003 cr250 mikuni ( TMX11C A ) on it and it runs great.

From my understanding, the TMX can be made to work well, it's just the PWK is easier -- and less sensitive. I've had success with the PWK in part because the "cave man" aspect of their operation and adjustment is straightforward for a (man-) cave man like me.

Plus, here in Houston, it can be 60 degrees and no humidity and then 90 degrees and about to rain in the same day, and the PWK seems to be less touch about those types of swings. Some things I used to think were cool when I was a kid -- like having a bunch of clickers and suspension adjustments -- and tinkering with jetting to find that razors' edge -- as I've gotten older (err, fatter), are less appealing. I suspect that with DJFMX's youth and mechanical expertise, it's a breeze! Don't turn 40, DJ!! haha

Thanks, it does not have the solenoid so maybe it's a 97?
