Keihin jets for all Keihin carbs
going RM is a great place to buy all your Keihin jets not just dirt bike and ATV's. I purchase all my Keihin jets for Triumph bikes here at RM. Far cheaper than going to Triumph or Triumph sites. Great description in the jet guides to make sure you get what you need.

Great Product
Perfect replacement part. Noticed smaller screwdriver slot than my old one but still works perfect. Very happy with the end result of this product.

Nice jet to use
Replacing this fixed my problem! It was the right part the first time and it came quickly. The layout of the parts list is makes finding the parts for my vine easy!

Pilot jet worked fine
Bought this for a 2002 KTM 520 EXC. Turned out to be too rich for Colorado Springs, but the part fit fine.

Happy with the jets
I was glad to see they had some OEM jets also, they delivered quickly and where accurate in their order.

I will be glad to order from Rocky Mountain again.
