What are the best mods for a 2009 CRF450?
The Shop
If you like it then ride it. If you're not sure if you like it then nothing anybody on here suggests is gonna help you either because you wont be sure if it helped.
Ride the thing and try and work out wat you like and dont like before you ask randoms who've never seer you ride before.
One thing i will say is it, those things were renowned for being harsh on muffler bearings, keep an eye on them, seriously.
I had the same problem with my 09 it finally stopped running all together, I pulled the fuel pump out, cleaned the fuel pump filter and she was good to go, ended up spending the $50 and getting the fuel pump filter kit, did not have any more problems.
Getting it to handle well is the fun part, I spent a bit of cash and time with a local suspension guy (IN AUS) and got the bike to a point where I was happy enough, not perfect but for my C grade riding level it was fine, I know a lot of guys that spent the money on the rear link and were more than happy in the end.
For suspension absolutely spring it for your weight. The forks dive really bad and to help correct most of the turning issues you need to keep them from doing that. You can lower the rear with a link or knuckle to level the bike out some more and others seem to think that helps. To me it's gimmicky and caused more problems than it solved.
Other than that ride and enjoy. I had easily over 200 hours on mine of hard riding and it was solid as a rock. Easiest horsepower comes from an exhaust, that can bump it up to nearly 55hp.
Not much work once you have done it once and fixed the problem. Shawn is right about the idle speed, Check the manua but I am pretty sure it says to set it around 1700rpm, I know i had mine wound way up. I know a few people that had the fuel pump problem.
I could not work it out for awhile, I would go through a third or fourth gear sweaper and the bike would bog down like I was in a gear to high, I could kick it down and it would have no effect. Then it got worse and would to the same and just stall, Would then start fine, I had no idea and the day it finally died on me i spent weeks trying to work out what it was until someone suggested trying the fuel pump before getting the ignition checked. Glad i checked that first!
If you are a A grade rider ill stop with sugesting ways to fix the handling, think there would be a world of difference in our riding. Though the rear link seems to be the best fix from what I have read.
Pit Row
I had an 09, sold it after 7h, the main issue for me was the clutch that was heavy in pull, and you had to press it to the handlebar for 100 % release. This ended with me being forced to use four fingers after a few laps, because if I didn't, I stalled the bike EVERY damn corner. I had some issues with the chassis as well, but being a C/B-rider one really wonder how much is in the head. Also, I newer figured how to check the valve clearance since you are supposed to bend the feeler gauge or something. Hard to start as well. Still very good looking bike, good power, liked the linear power and the ergos was amazing. Still I didn't regret selling it though.
You look to put Brembo stuff on this one?
As far as the power goes it all depends how fast you are and the type of riding that you do. My bike has an FMF exhaust and a remap and its way to much for me. I wish that my bike was stock now.
Yosh full system (had the o2 sensor + computer remap- but switched it back because it didn't help from what I could tell)
Flywheel Weight
Hinson 6 spring full clutch + basket
Factory connection revalve + linkage pull rods
1 tooth larger rear sprocket
Bullet proof reliable.
