So here is my delima... I currently race a 06 CRF450R that has more mods than I can mention. I have kept my bike in perfect shape but I am getting my butt handed to me on the starts. I can chase the pack down and finish pretty well, but I wouldn't have to claw my way to the front if I could get better starts. The input that I am getting is that the newer injected has the edge... I personally cant say for sure, since I have a small fortune in this 06 and could never justify parting with it and starting over. I have been kicking around the idea of upgrading to the newer 450 but is the performance really that huge?

I have an 09 and I don't think a carb is your problem. Practice starts.

i rode an 09 and did not notice any great power over a carb 450, just different...a little jerky too. i installed a 480 BB kit in my 06 and it hauls the mail. there is enough room in the 06 to go as big as 500cc. the larger bore smooths out the power, but when you roll it on it continues to pull (lots of power, but very controlable). nice mod.

I love my 06. I'm thinking of getting a holeshot device but I don't have any first hand experience with them. Some people swear by them, you might like them. What kindof traction are we dealing with? You mentioned sand?

On sandy stuff I always started in first gear, contrary to what everybody says about 2nd and 3rd gear starts. You jump out to about a bike and a half lead in the sand and speed shift the hell out of it about 15 feet off the gate and you'll keep that bike and a half lead.

I am now in Florida and the sand is definately a new monster for me to tackle. I am actually from PA and the D6 tracks there are mostly topsoil or topsoil/clay mix. so for me the sand is the worse thing I could have landed in, especially here, deep soft sand. Up north I was winning Championships, and now struggling to stay in the top 5.
The holeshot device was my next buy as well as trying new tires. Holeshot device is about the ony thing I haven't added. Kinda feel wierd about them though... just doesn't seem to make sence, but then again I am kinda at my wits end with these starts. Tire selection is a little defferent for me since I get mixed info on the tire compounds. I was leaning towards the MX11 but hear they chunk apart. So I have been kinda in limbo... also heard the sand race tires dont corner worth squat... then again... wouldn't know...
I do start in second, but admit I have never tried a 1st gear start here since we moved... worth a shot... can't hurt me any worse than what I have going on now.. lol
Thanks everyone for the input! Anything else please feel free...

rejet the carb sure and tune it. If you have not gotten a ALJ or R&D power bowl, you are missing out on a lot of potential of the carb there.
