Storm jets.

[china007]

Need help on what to upgrade the jets to after exhaust upgrade. Current jets are 34 and 105. Ordered a set of keihin clones that are small and do not ETF. Any suggestions.

Thanks

It's the pz30 carb

What jets did you order and where from? Have a model number for them?

Generally, the PZ clone carbs run a 99101-393 main jet

As far as jetting suggestions, I am going to use a TT250 as an analog - similar counterbalanced engine and Keihin carb replica with the same jets.

With an exhaust a 112 main seems like a good starting point. I would recommend a 115 to start just to be on the safe side. Keep in mind that your altitude and the current air temp will change what jetting you need. If a 112 worked for somebody in the summer at a similar altitude to you, you may be looking at a 118 if the temps are on the cold side where you live. If they were at a lower altitude, this will change it as well.

The best thing to do would be to pick up a range of jets, 110, 112, 115, 118 would likely suffice.

I bought these jets from amazon.

Yes, you definitely ordered the wrong jets. Those are the jets often found in PWK flat slide style carburetors.

lucky me. So can I order the ones from this posting. Would it be easier to order a different carb. I was really hoping to ride given this nice weather in Puget Sound WA. My elevation is also around sea level to 900 feet with occasional trips to the mountain/hills.

http://www.ccwthariders.com/uploads/...ing_manual.pdf Here is also a link to tuning the carb.

I don't need much help with carb tuning personally , but maybe it will help others.

If you order the right jets or a new carb, in either case you will have to wait, so why not just order the jets? Any carb you order is going to need jetting anyway.

Would these work for the PZ30?

Thanks.

Since there are variations to the PZ30 depending on who manufactured it, the best thing you could do is to take the jets out of the carb and confirm their style and dimensions. Most likely the pilot/slow jet is the style linked by XDoubleXA, but it would be a good idea to confirm before ordering.

lol megadan that post was not for you but the basics for someone like myself and in case anyone reading this had questions they would see that. You are right so it will be jets only. You think there would be any issues riding it until I get the jets in or will it cause some damage.
Thanks

It will be very lean with that 105 main jet I wouldn't personally ride it, but if you stray from going WOT for any length of time it should be ok. It might not run very well though. It may be a good idea to shim the needle, or move the clip down a notch or two to help with the mid range throttle positions until you can get it jetted properly.

Here is the two jets measured by a ruler.
