I have 95 Yamaha yz250, currrently has a PKW38, stock engine, will this carb need to be re-jetted to run correctly? No serious racing, just bought it

It really depends on what has been done to your bike to determine how it should be jetted. for my trx250r stroker ported motor i run a 185 main , 50 pilot, and DGH needle middle clip.

upon putting this on my 96 cr250 which used a keihin already just not the better airstriker, I took the needle and all the jets out of my existing carb and it's spot on jetting and run great.

Hey, I had a 95 YZ250 and I also have a Suzuki RMX that I just put this carb on...It worked awesome on the Suzuki and was going to order one for the YZ...before I did I swapped carbs. The PWK made the YZ smoother BUT it took away ALOT of the hit coming on the pipe. The carb worked fine BUT it seemed like it took away so much of the powerband of why I enjoyed the YZ in the first place. I put the TMX Mikuni back on the YZ and the power came back. The carb was jetted correctly but it just took away too much, Save your money and stick with the old school carb...Surprisingly the PWK worked great on the Suzuki...Go figure.

Absolutely need to rejet. Exact sizing depends on altitude check Fmf's website for approx recommendation. The jets that are in your old carb should be closer than what is in this one.

This was a great question. My 2 cycle 33cc is having issues and I was wondering the same thing. Did you end up purchasing it? If so, how does it compare now that you've had both?

I bought this carb awhile back, And im pretty sure that it matches all the specs of the stock carb. I didn;t take a micrometer to it or anything, it just fit right on the stock parts. (motobravo bari TPD 50cc)I also wanna add; Idk why amazon asked me this question, the seller already answered it x.x

deborah, i have the same engine & when i opened the pkg, it was missing a carb. i called the shipper & one was sent that week, no questions asked. if your engine is out of warranty have you tried tightening the housing bolts. if not out of warranty call the shipper & you should get the same service i did, hope this helps,

I bought the one that was listed for Harley engine. Look up on the pc racing page, see if they list the one you need.

I put this carb on a stock 1600 motor and have not had any issues with the jetting.

Sorry i do not know about BMW motorcycles. My experience with this carb is just with Harley Davidson IronHead 1000cc 1957 to 1985 Sportsters. The VM38-9 carb was set up specifically for these by Jerry Branch [a well known IronHead Sportster expert] back in the 60s or 70s. It may work if the bike is an equivalent ~1000cc engine. I suspect it would require some carb tuning runs.

I bought it to put on a 383 stroker it does really well right out of the box. runs out of gas about 4800rpm. It should do fine on a stock 350.

I had to tweak the carb on my 06 Sporty. If you have EFI then it too will need some tweaking. And I installed Screamin' Eagle air kit. More power instantly and way more responsive. If you do one you gotta do em all.

I bought one of these as the correct replacement for a '71 dual port engine...it runs fine, no jetting issues that I can discern...my engine is dead stock, if you've got a stock engine that recommends this carb, I'd say go for it. Robert H.

I had to rebuild my carburetor on my Echo blower and replace all of the fuel system and it now cranks on the 1st or 2nd pull and works like a champ. There are videos on youtube that will take you through the steps.

Sounds like fuel starvation, my saw was terrible when I first got it, very hard to start. Adjust the carb. Runs like a champ now.

There are various versions of the VM38 carb. The VM38-9 was set up by Jerry Branch [Google the name if unfamiliar] in the 60s or 70s specifically for stock Harley Davidson 900cc and 1000cc IronHead motorcycles. This includes any or all of Main Jet : 330, Pilot Jet : 30, Needle Jet : Q-2, Throttle Valve : 2.5, Jet Needle : 6DP1, Air Jet : 0.5 You may need to change any or all of these. Only another XS650 owner who has done this would know. I have one on my 1978 IronHead - runs perfect right out of the box, no tuning needed at all.

There would be no reason to but a 4 bbl carb and make it work with a 2 bbl adapter. Get the intake and because it's only a 4.3 you will have to do some adjusting to get it to work properly. Depending on the altitude where you use the boat most and proper jetting will be required. Fortunatley this is easily done with this carb.

The carb needs cleaned with carb cleaner spray or if that does not work you will need to take it off the saw, take it apart and clean it and re-install. Fuel that sits for a while causes this to fact. Empty the fuel tank between usage.

Likewise, you're asking buyers here...I can tell you that this carb comes with "standard" sized needles and jets, which may not work for your bike. When I bought this carb I had to purchase the correct main jet and needle for my specific needs...
