So the '06 and '07 Honda HRC Power up Kit the same?

[tnsxsear]

Just trying to make sure before I order the one for the '06 for my '07 450er. -Paul

yes they are...

[tnsxsear]

Cool. I wonder why they have different part numbers than. Oh well. Thanks

The jetting is slightly different. I believe that the needle for the 06 works in both carbs, but the needle in the 07 kit works only in the 07 (at least from what I have heard?). Otherwise it is the same thing.

My '07 kit came with both needles. One for an '06 and one for an '07.

my friend just got his yesterday and he said it said that when you run the kit you suposed to swap out the piston every 15 hours. Hes not that motor savy but is he right

15 mx race hours maybe but I wouldn't think for the average trail rider

Make sure that you get the kit that says its for 06-07. The only thing different from 06 to 07 is there is an extra needle in the 07 kit with a little ball on top. It is the only one that will work for the 07. I went through hell trying to find that needle because i bought an 06 kit for my 07 thinking that they were the same.

Well I got my HRC of ebay and its an '06 and I have an '07. Does anybody have the part number or know where I can get the needle I need.

I got the 06 kit in my 07. It has the 06 HRC needle in it. Been running it for over 2 moths with no issues. I think you can use the 06 needle in the 07, but not the 07 needle in the 06 as someone stated in a earlier post.

Thats interesting...where did he get that info from...honda or someone else and did they say why a HRC kit can cause a problem with piston

With that said i have just had a problem (saturday) with an 07 trx450 with 16hrs use
Guess what cracked piston and are trying to find out why this has happened. I have HRC cam with porting, but race mx

That is Honda just being Honda (conservative); I have between 30 and 50 hrs with my bike. It is HRC kitted and still has the stock pison, still runs good too.
