Reply from Tim Olson-MXA:

Honda changed the ignition map a little, but since it probably works better

on the '02 also they just decided to sell the same part for both the '02 and

'03 bikes.

Followup from me:

Dear Tim:

With all due respect, that still does not jive. Lets say some guy steals

the CDI from my 03 CRF to put on his 02 to gain this performance. I then go

to my local dealer to order a new CDI. How the hell am I guaranteed that

the new CDI I get is the "Remapped" CDI designed for the 03 (but also

improves the 02 according to you guys) and not the 02 ignition that does not

perform as well as the 03???

Who's your source and how can you back up this claim????? There are several

thousand readers of and MXA that are on the edge of their

seat waiting for this response......please clarify!!!!


Dave Garzoli

Personally, I find his initial explantion to be pretty weak and I can't wait to see if I get a further response from him.


Wow, that is something. I'm with you and your response-----if the number is the same then how does a guy know if he is getting a remapped 03 box or a 02 box that has been on the parts shelf for a year?

BUNK! I think it is great that MXA thought enough to give you an answer-----BUT I think they are making it up as they go.

Thanks for the effort of asking the question. Be interesting to see if it and their answer ends up in print (readers questions) as the "cast in stone because it's in print" God's honest truth. RR.

Have you asked Honda? You'd think they'd really know the answer.

They will know, but will they tell :)

If it's truly a new part Honda would have a new part number for the '03. That's the way they've always done it. Unless they changed the mapping mid-run on the production of the '02's so that all parts in the system are indeed new (to '03 specs) then it is the same part. I could probably get in touch with a Honda reginal service manager if I tried to find out the truth.

Have you asked Honda? You'd think they'd really know the answer.

I would love to but I cant find anyone other than my local dealer and service techs to ask, and they all agree with us. No new part number no change. Ive search the web over looking for a phone number or address to ask the question straight to the factory to no avail. If anyone here has a contact of a reliable source at Honda that could settle this I would appreciate it.

Here is my 2cp...

The 02 ignitions had their own part number. When the 03's came out they had a new part number. At that time they probably dropped the 02 CDI's and listed the 03 part numbers for the 02's.

you guys believe that Elvis is still alive too, don't you?

although my $.02 will never convince most of you (even though i have more experience in production than i care to admit or you could imagine)i will say this. the honda ignition was remapped at some point in 02'. minor remapping is simply a software change, therefore the components of the ignition ARE IDENTICAL. since the changes were so minor (despite what some people on this board might think) and it is compatible w/ the 02's, there was no point in wasting the manpower to change a stupid part #. so for all the 02 CRF owners that got smoked in their last race or couldn't climb a hill bc they don't for certain have the career altering power of the remapped ignition, i guess you'll have to buy an 03.

That sounds reasonable but that's not the way Honda does things from my experience. I've worked for a Honda car dealer for over six years now. Computers are updated all the time. Usually it's a very, very slight change to the parameters of a sensor. Some peoples driving habits cause engine to think that the oxygen sensor is malfunctioning and it sets a check engine light so Honda releases an updated computer with a very slight change to the parameters so it recognizes this is just a driving style. Some people put 91 octane gas in their Civics instead of 87 and drive like an old lady. It causes a carbon buildup on the valves and sets a check engine light for a misfire... Honda releases a new computer... you know the story. Anyway, those are just two of many examples and every time, although you'd think the new part would supersede the old one it doesn't, the new part always has a modified part number. Other Japanese manufacturers can change a part in some way (say an oil filter shape) but it still fits all the same applications so they retain the same part number... not Honda, they will modify the part number every time.

Ok, im bored so I'll bite....

If you spent so much time in production then you would know part numbers arent stupid or trivial. Any manufacturer will change the part number of any part that has changed from year to year. Even if it is a software change. As far as the manpower to change the part number, it is just like the ignition map... and I quote... "simply a software change". With any CDI the electrical components most likely stay the same from year to year. The software is the most important part. With software (and the exact same electronics) you can completley change the power band of an engine.

I would be willing to bet that if the part numbes have not change then neither has the ignition (no mater what the magazines and salesmen say). Sounds like a marketing ploy to me in that case.

      Jeremy Martin Leads the Charge for Wiseco Riders at Daytona Supercross
      Christian Craig Turns in Career Best in 450 Competition
      MENTOR, Ohio (March 13, 2018) – Jeremy Martin showed the way for Wiseco-sponsored riders in Saturday night’s Monster Energy Daytona Supercross presented by Honda. In a season marred by bad luck and misfortune, Martin put together a near flawless ride to earn his first Eastern Regional 250SX Class podium finish of the season.
      Martin qualified eighth for the division’s annual visit to the World Center of Racing, finished fourth in his heat race, and came home second in the 250SX main event, missing his first win of the year by less than a second.

      “It’s Daytona, a real man’s track.” said Martin who sits fourth in points. “It was the toughest race of the year as far as fitness. I had to slow down a little bit, halfway through the main. I was getting close to (race winner) Jordon (Smith) and I was starting to think about where I could make a move on him, then I made some mistakes and he got away from me. Couldn’t quite get close again, but it’s good. We’re on the podium and in contention for wins again. That’s something I haven’t been able to say in supercross in a while. We want to get wins and now we know it’s coming.”
      Martin’s podium was a bright spot, but the rest of the event was rough for the GEICO Honda/Factory Connection squad. RJ Hampshire crashed hard in his heat race and had to be transported to a local hospital. He injured his back and ribs, but shoulder pain left him with the most concern.
      “I felt good on the bike all day,” said Hampshire via his Instagram account. “Had some pretty good speed and my foot just slid off hitting my shifter in those rollers during that heat race. After seeing the pictures from the crash I’m very thankful I didn’t take a shot to my head. I have some fractures in my T3/T4 in my back and ribs. Also have some damage to my lungs which is why I’ll be spending a couple nights in the hospital. I’ll be getting some more checkups this week on the shoulder also.”
      Cameron McAdoo, the third member of the team, was unable to compete at Daytona after being sidelined with a hand injury two races ago in Atlanta.
      Across the paddock, in the premier 450SX Class, Christian Craig got the call to fill in for Team Honda HRC. With the team’s regular riders Ken Roczen and Cole Seely out with injuries, it was up to Craig to carry the load for the factory team, and the upstart rider didn’t disappoint.
      The San Diego native was solid in both qualifying sessions, won his heat race and snagged the holeshot in the division’s main event. After relinquishing the lead to eventual winner Justin Brayton, Craig continued to show he was up for the challenge. The 26-year-old rider raced for second and third for most of the 20-minute-plus-one-lap feature before losing one more spot in the late goings to bring his No. 32 Honda CRF450R home fourth in the final rundown.

      “I had a great week testing with the team,” commented Craig. “They came down to Florida right after Atlanta and I feel like we really improved. Just getting more time on the bike and getting more comfortable was huge. I started off race day feeling really good. My qualifying position didn’t really show it, but overall I was happy with my riding. It’s all about having fun out there, and man, that’s what I did tonight. I was up front in the heat race, fell to third, but then the two guys in front took each other out so I ended up winning. You can call it luck or whatever, but I just put myself in a good position to capitalize on people’s mistakes."
      “I had a good gate pick and some confidence going into the main. I grabbed the holeshot and led for almost the first lap, but [Justin] Brayton got by me pretty quick. I stayed second for quite a while. I just rode my hardest and did my best. Unfortunately, a couple guys got by me so I ended up fourth. The track was so tough. This is only my second time racing Daytona and last year didn’t go well, so I really wanted to get some revenge this year. It’s better than the week before, but man, I was so close to a podium. I just need to keep putting myself in good positions and work on getting better each weekend.”
      Monster Energy AMA Supercross rolls on this weekend when the series visits the “Gateway to the West” for its annual race at the Dome at America’s Center in St. Louis. The 11th of 17 races on the 2018 supercross calendar will be televised live on FS1 Saturday, March 17, beginning at 8 p.m. Eastern Daylight Time, 5 p.m. Pacific.

      I have a 03 450 that I just got and it runs great! I love my bike and am big on preventative maintenance. I have searched the threads on TT and have not found any descriptive threads on how to check valve clearance or adjust them. Just by looking at them, I can see that the intakes need to be shimmed and the exhaust valves can be adjusted quite easily unless one needs to be adjusted differently than the other.
      I tried to do it last night, and lined up the marks on each side to get the piston to TDC to check adjustments and could not get any readings on tolerances on either the intake nor the exhaust. I moved the crank a little bit forward and got a .011 reading on the exhaust valves. I read in a thread that the spec was .011" for the left one and .014" in the right for the auto decompressor. The spec I am using for the intakes is .006" Are these specs correct? :excuseme:The only issue is that the adjustment for the exhaust valves is one and the same. Different from my KTM where you can adjust each valve individually.
      No matter where the cam was on the intake valves, I could not get any readings. Does anyone have a thread, website, downloadable manual, or article on checking and adjusting valves in these beasts?

      I recently replaced water pump and seal after I noticed that my '02 CRF450R was spilling coolant on easy trail rides. After the water pump swap (which was successful), I noticed the same problem. It's interesting - the bike only spits coolant (I mean a LOT of coolant) after passing anything above 1/2 throttle. The bike makes this weird 'gurgling' noise, like trying to suck through a straw when your glass is almost empty. This is weird because I properly bled/ burped the radiators with coolant, and filled them to normal operating levels. The coolant spills through overflow hose. 
      anyways - I swapped the radiator because I thought maybe the bike was running hot. I purchased oversized radiators, bought a 1.6 radiator cap (with a temp gauge) and bought engine ice. The bike runs very very cool - the temp gauge allows me to see this. Still, the bike shoots coolant out of the overflow after going above half throttle, making the same weird gurgling noise when it does. Bike has all of its power, top end was replaced not too long ago. 
      I'm lost and don't know what is wrong with the cooling system in my bike. How do I make the bike stop shooting out coolant, and stop making the weird gurgle noise??? Any advice would help me!!! Thank you!

      I have a brand new Barnett Extra plate setup still in the box. It replaces the judder spring with a regular fiber. My old clutch had a judder spring break which wiped out the stock clutch. I was in a bind ordered this kit but it ended up coming 2 days later then it was suppose too. So now I don’t need it asking $180 SHIPPED 
      —“Complete Extra Plate Kit- consists of 8 Kevlar friction plates, 7 tempered steel plates and a set of springs. Provides maximum clutch capacity.”—
