What Mods Should I Start With?

[robertwarreniii]

I just bought a '05 450r, completely stock. I want to add some performance mods. I was wondering what you guys recommend starting with to get the most bang for my buck. I was thinking along the lines of a new pipe or maybe a whole new exhaust system all together, a K&N air filter, and a jet kit/ignition module kit. I also would like to get some nerf bars for it. I was leaning towards the Pro Armor XC. Any suggestions would be awesome.

I would say get an exhaust to start, open the airbox lid and re jet, IMO get a UNI filter. Depending on what riding you do would determine my next mod.. IF your going MX I would say work on suspension and width. OR your an XC guy go w. a steering stabilizer, some skid plates or sprocket guard/ Rotor guard.

Pipe/filter/cam IMO

^^ Agreed^^ All three of these at once. This will last you a
month. (You'll want more) Then you have to port the head.

Intake, pipe and Porting... u can call Titan Motorworks. I was able to do 3rd gear holeshots with stock gearing after they did my motor.

i agree with this but would add revaved stock shocks to the xc part if you have the money. just get a slip on exhaust full system really isn't that much diff. i would not tear into the motor to much stock is the way to go. i have had 2 big bore motors and they lasted about a year i have had a stock motor last for 3 years and thats when i first got a quad and did little to maintain the the motor.

Im sorry... a 3rd gear holeshot? im saying "bs" unless you slip the clutch like crazy. or maybe if you were running 12/41 gearing would this happen. i have had DASA, Baldwin, rage and sparks do motors for me and not one of them could do a 3rd gear start with stock gearing.

im callin your bluff.

im not saying that titan dude cant build good motors but i dont think they are that good.

I understand your theory. I've run both stock and bored and
stroked engines. But I would rather ride a bored and stroked
engine for a year, than a stock engine for ever. IMO.

thats what a racer would say, but the weekend warrior wants something that lasts. Me on the other hand. I used to race a lot and I put quite a few races on my R. About 25 actually. My motor internally is stock with the exception of a 03 CRF cam. I run a rossier pipe with a open box with UNI filter. Thats it. Its on 05, bought in 06 and its still going good three years later.

i run a 11.5 piston, crf cam,open lid,needle,hmf slip-on and it runs hard. im very pleased with it. 14/40 gearing. even runs good with my 22 " rocky trail tires. on 20,s ,it rips
