I am going to Silver Lake Sand dunes in a couple of months and I was wondering what I can do to my 450R to ensure that I can take stock 660s and Banshees no problem(still lil worried about those 2 in a race).
I want to spend less then 500 if possible beacuse I still have to buy paddels and dont have a lot of extra money to dump in my quad right now.

 

remove air box lid or air box.
K&n filter
jet it
add a pipe (DRD if you need to be quiet)

Add somne radlites if you do night riding for bling. www.radlites.com

 

I have just put a stage two hot cam in my 2005 trx 450r. I have been told by some people that after about 60 hours I will need to completely change my valves and springs. Is this true?

 

I just got my 450er and it has a full yoshimura pipe on it. I havent had much time to really get to ride it yet, but this things is a lot faster than I expected. I would go pipe, filter, jet kit, and you will be fine.

 

If you are worried about spending alot of money I would recommend you getting a Honda Hrc kit because they are very cheap and can add a good amount of power to your bike.

 

I dont think a 660 would be a problem against a our 450r but im no sure about the banshee. never seen the two race.

 

No, this is not true. A Hotcam is a drop-in cam, meaning no changes are needed to the valves and/or springs. A Web Cam is a different story.

 

What year is your 450R?
I have an '04 and I went with a stage II Hotcam, UNI Filter, Cut open air box lid, Slip on pipe, and rejet the carb. I have a 185 main, 50 pilot and dropped the clip on the needle to the bottom.
This can all be done for around $500.00 if you can do the work yourself.

You should beat stock Raptor 660's and stock Banshees with this setup.
