Crf450R Rumor

i have always rode yellow... even my street bike.
but if honda puts fi on the 450, i will sell my rm250 and buy one at all cost.

i know suzuki will eventually but i cant wait...

i don t think jap will move to fi in mx bikes,carb are more efficient and less cost,also they don t want to push the price of bike at stars

Hey rickyd, I see our Saturday ride convinced you to seriously check out the CRF huh? I don't know the answer to your question, but it's entirely possible that the salesman didn't know what he was talking about. When I went to look at my new KTM on the sales floor, the guy trying to sell couldn't tell me about half the changes they made to the bike between then and 2003. At least I had the info from the internet. Now hurry up and buy one so I can try it out!

Awesome. I'll see if I can go into Redwood City Honda sometime this week and see if anyone there has heard about the fuel injection rumor on the 2005 CRF450. I'll let you know what I find out.

see thats the great thing about fi.. no tinkering. the computer will automatically compensate for simple bolt on's. larger items ( ie: full exhaust ) then a remap will need to be done. it is so much easier than you think. i learned about fi when i was a kid working at a turbo buick race shop...

Honda is a pretty conservative company in a lot of respects, and they clearly have a very competitive and cost effective setup using the reliable and easy to tune FCR carb. I wouldn't hold my breath expecting Honda to be the first Japanese company to put EFI on a dirtbike.

i bet people said the same about them trying an aluminium frame! :) although i doubt we will see FI on a big 4 prody bike, it would be cool, lets hope that it wont take them 5 years to make it work!

right, thats my lot in here, i am off back to my 2strokes........ in the mean time, dont get your valves out of adjustment guys! :clue: :joke: :laugh:

Well, there is a big move on street bikes to FI on the last couple of years. I got a honde cbr600rr and it has FI and my friend has the older cbr600F3 that has the carb set up. The FI even on a street bike is still a little crude at low thottle positions. The transistion from accelerating to engine braking back to accelerating is a little jerky, kinda like an On/Off switch. On the carb bike, it's alot smoother.

The one place where i see a big advantage is starting the bike, FI makes it so easy and smooth when the motor is cold. No choke button, no sputtering, just press start and it fires up right away.

IMO FI is just the logical next step for a 4t bike.

jackdrinker, what turbo buick shop did you work at? i have an 86 grand national, do you have turbo buick? i might have to sell the car though :ugg:

i worked for modern musclecar for a few years, my buddies uncle is mike licht.
yes i have a buick.. 87gn to be exact.
ops intercooler
ta49 turbo
37# injectors
th downpipe
atr pitbull single 3"
orange strip converter
terminator chip
and a few other secrets..

hey guys,
my take on fuel injection is that it is a very efficient, very simple to maintain, reliable system. Whether or not it has a place on a dirtbike is a different story. First of all, it compensates for changes in altitude, doesnt come out of adjustment, and is computer controlled to provide the best spark, air, and fuel mixture for power. Any roughness seen throughout the band may be associated with incorrect tuning or being out of mechanical adjustment. FI should run smoother and pickup as quick or quicker than a carb setup. Honda also seems to have faith in the idea of fuel injection for the two wheeled world, just look at the super sucessful cbr 600 f4i. Not only that, Ducati has been using weber marelli FI in their street bikes for years, and aint many japanese piped bikes running away from a stocker duc. FI has huge potential and is extremely adjustable. They can be adjusted (the fuel map and timing and such) from a laptop in the pits, while the bike is being ridden. This is formula 1 technology currently, but nearly every team now has some system to find out what the motor is doing at every point around the track. They do this for a reason. Getting to feel for your motor and tuning it accordingly is an art, but an important one. Last time I checked every second (every horsepower on the front straight) counted for something, especially among your riding "buddies", right? I cant stress this enough. TAKE NOTES ON YOUR BIKE!!!!! Always, Always, because it can help you learn what works best where, how you tuned it when it worked, how you tuned it when it didnt, what clicker settings were good for that whip landing, what grips and bars you didnt like, what noises the bike starting making before you grenaded the head...... You get the picture. Your bike should be, in some respects, like your woman. You gotta know her, listen to her (more the bike than the woman on this one), and you gotta take care of her, cuz then she takes care of you. Besides, your woman likes a winner, even if she says she doesnt care if you get last place.

jackdrinker, thats really cool you got to work at modern musclecar, mike lict is a good guy to deal with, i ordered plug wires of him. my car has almost the same mods as yours but i was planning on going with a pt51 turbo, from 009 injectors and a stretched stock location intercooler cas.

lonewolf,
although cas makes a great piece, getting it WILL be a problem. Guys on turbobuicks.com have been screwed so many times over by him.
Have you had any problems with that pt51?

jackdrinker, i dont have the pt51 yet, it was gonna be one of my next mods. its actually a toss up between the te44, ta49, and pt51. i have heard of problems with the 51 though. as far as CAS i know there is problems with them, but i dont know where else to get a stock location intercooler, maybe Mease Performance but the has been problems with them too. how about dropping me an email, we can discuss cars there, its Lonewolf86gn@aol.com, moderators might be getting mad because we are way off the topic.
