Are they the same?

Are the 2006 and 2007 HRC kits for a 450r the exact same? Im told that the main jets are different. My 2006 HRC kit shows a main jet #162. Wanting to know if I installed this on my 2007 if it would make a difference.

hey man there the same!!! both have the same part number!!! so yea go ahead and put it in your 07

Should be the same, however I thought the 06 and 07 needles were different.

well i was told by the honda guy that the carbs were the only thing that changed but i looked up specs on both year models and they are both Keihin 40.0mm flat slide with throttle position sensor (TPS). So the needles should be the same.

for those of you that might have the same problem here is the deal. The 06 and 07 HRC kits are exactly the same except for the jet needle. When you buy a 07 kit it is labled as an 06-07 kit. The only thing that is different is it comes with theneedle jet for the 06 and a different one for the 07. This really kicked my butt but i finally figured it out.

Well whats different the needle or the main? They're two different things.

[Dave400ex]

I'm pretty sure it's the needle.
