thanks ,

 

I put a 13t on mine. It makes a big difference. Ireally like it for trail riding. Don't have to slip the clutch nearly as much now.
So far that's all I've done. Will probably put a new pipe on some time soon.

 

i think thats the first thing im going to do is the sprocket......im wandering if someone has come up with a modified end cap like they have for the ds.....i kinda like the polishied exaust it has on it..lol..

 

Ive seen modded end caps for the 450r on ebay, not sure how they work.. but they look nice.

 

what is the "HRC" kit and what does it include?

 

the HRC kit comes with a new air box lid that has a hole in it, an snorkel extension for the intake, a new endcap for the exhaust that has a screen type spark arrester, you remove something from the exhaust, i beleive the stock spark arrester, you get a bigger jet for the increased flow, and you get a new cam. i've heard a lot of people say that it has a noticable power increase, but not as much as they expected considering they got a new cam. the stock exhaust is pretty good, so there's only a little room for improvement. hopefully honda will make a better cam, once they do that i'll invest in the kit.

 

thebigshow- the kit is good but not super. The airbox lid that comes with it is exactly the same as stock they just cut out spots in the lid and then put a plastic mud splash guard that goes on the lid, if you look at your lid, it already has the spots lined out that they took out of the lid. Also if you want an end piece could probaly make you a good deal on one, we got an hrc kit, but already switched to a full Yoshi system, we only rode once with the end cap. Also we are running a pro flo kit! it all seems to be working really well! it is an alright kit! Anyways let me know if you need any other specs!

 

thanks guys, do u think opening up the spark arrestor will make the same power as an after market pipe?
