Should I use OEM Keihin or Chinese jets?

[HillbillySnowman]

Hi all
Want to start the jetting process on my bike and I have found both Keihin branded and no name branded jets on Ebay. The Keihins are a bit pricey at 7 dollars each while the no names are 50 dollars for a pack of 27. Which ones should I choose? has anyone used the Chinese un branded jets? They don't seem too rough in the photos and would allow me to get a wider range for cheaper. Any input would be appreciated.

Pay a couple bucks more for OEM jets.

Go to jetsrus and buy keihn jets

You could also go a different route and get a JD Jetting kit. My dad used one of their kits and they are awesome. Kinda pricey but worth it.

Jetsrus.com and I have bought those OEM and other brands. Haven't had an issue with either. Keeping a clean air filter and not letting gas sit in carb will pretty much guarantee whatever jets you use will work just fine.

I would use Jetsrus.com however I am in the predicament of living in Australia so any price you guys pay is essentially doubled. I have found a business in Victoria who sells Keihin jets for $6.50 Australian so I may aswell go with them.
I'll buy a couple sizes smaller and larger so I'll have the jets I need for winter.

$6.50 is not too bad given your circumstances. Less than $20 and you are done. Probably the cheapest price you will ever get away with when it comes to dialing in a bike [emoji12]

I realize this is a very old thread but thought I'd add to it in case a search brings someone here. I bought a jet package off of amazon that isn't Keihin and I use them along with whatever Keihin ones I have. I think the key to using off brand jets is doing your own Quality Control on them. I do this my using a magnifier to look for bad machining marks or other problems (haven't seen any yet). Then, and I think this is the most important part, I check the relative sizes of the jets (vs Keihin, or whatever one I'm replacing) by using a pin gauge set. With these pin gauges I can positively tell if the hole in the jet is larger or smaller than the one I'm comparing it to. So far, these aftermarket ones have been consistent there too, but I always check to make sure I'm not putting in a slightly richer jet when I want a slightly leaner jet.
