Fine layer of dust inside airboot...

OK, now I'm frustrated. (new to TT, so this may have been addressed). I installed the complete PC Racing proseal kit and I'm still getting a fine layer of dust inside my carb boot (after riding in very dusty conditions). Seems to be coming from the right side. Anybody found a cause/fix for this????

I get the same, have resealed the airboot and around outside of pc plate. Tried different filters and nothing seems to cure the dusting. Always in super dusty conditions I am always certain to find a powder like residue on the right side of the airboot.

Even though I contiue to piss people off here I will continue to say....... I have a stock air filter and a stock air box. When I install the filter I use a <b>LIBERAL</B> amount of grease around the sealing surface of the air filter and I have never even found so much as a single SPECK OF DUST in my air boot. I have been accused of not riding in "dusty conditions" and everything else, but Im telling you I have been riding my bike all summer long in all kinds of conditions not a speck of dust, dirt, rocks, gravel, talcum powder, flour, nothing. Just use a thick bead of grease and it will seal perfectly. :)

I dont have much of anything get in my boot either! I do see a speck or two in there sometimes, but that could be due to removing that tight fitting filter from the box. I hate using grease on the rim, so I just saturate the filter rim with excess filter OIL and dont have a problem yet!


I am with you feetup&sliding. I sealed all joins in the airbox with silicone and cover the filter rim in thickish layer of grease and don't have problems. I am not calling anyone a lair here as i see guys with dust in them all the time. I think its one of them X File things.

A place i have seen them let in dirt is the slot (hole) where the filter cage bolt goes through, i also put some grease around that.

OK to all those hollier than thou guys: Hey this is one of those mystery of the universe things. Why do some guys have trouble with valves and others don't? Before you guys pass judgement on our problems with "I grease the sh** out of mine" or "oil the lip more", if you don't think I have tried all of that and more you are mistaken. I have pretty much lead myself to believe that this bike sucks dirt somehow someway. If you so called experts want to swap airboxes and carb boots, we could see if your fixes actually work. The guy asked if anyone else had the same problem and knew of any fixes, not if you guys could pass judgement on our filter cleaning abilities.

Hey E-WA Go and get a life :)

No one here has "passed judgment" as you put it AND none of us claimed to be experts. This forum is about sharing experiences more than anything.

The guy asked if anyone else had the same problem and we shared our experience PLAIN AND SIMPLE.

For the record and i repeat. I have seen some leak and others not. I DID NOT SAY THEY DON'T KNOW HOW TO CLEAN FILTERS.

I even offered some constructive advise of what i have seen to be a problem.

A place i have seen them let in dirt is the slot (hole) where the filter cage bolt goes through, i also put some grease around that.

NOW, i think you should go back to bed and THIS TIME get out on the right side.

I read somewhere that Honda changed the air filter on the 03 because of sealing probs with the 02 (many complaints). I've seen and installed filters on both 02's and 03's and the 03's filter seems to make a tighter fit. Although my comments may not offer any solutions to your problem, perhaps its clears up why your getting dust in there.

I took the boot/air box apart, resealed with RTV silicone, use the PC racing gasket that goes on the inside of the airbox to seal the filter, and have never had any leak. I check it with a flashlight everytime I change the filter (which is every ride). I don't trust the PC kit that has that thin little gasket replace good old silicone to seal between the boot and air box.

To add a bit more info here. I trimmed the filter cage where it butts up against the housing (the U shape part around the bolt hole) so it would pull the filter up tighter to the sealing surface. I really hate the design of the box that has plastic nipples protruding in against the filter mating surface. I dont feel the PC kit does enough to warrant purchasing it, but I do like the way the MX-BONZ kit eliminates the protruding nipples, sandwiches the boot and air box between two heavy -duty aluminum rings, AND gives you a nice flat mating surface for the filter to seal against!

Hope the info helps someone!

I will be buying the MX-BONZ kit for piece of mind in the future.


Another one i forgot to mention, which probably dosn't do much but we all do it here, is put a piece of course foam in the bottom of the air box to slow down the big hole in the bottom. I used the same foam i got with my works connection skid plate. Just cut a little square and slot it in there

I had the same problem. The MX-BONZ kit works well. You end up with a smooth seating surface for the filter. Still, make sure you use plenty of grease on the filter lip.

Just had this problem after running in a very dusty area.

I use liberal grease on my stock filter. When I took top off the carb to adjust the needle, I found a lot of dust coating inside of cover. There was also dust around the top of the slide. One area was very shiny with no dust. It was about where the hot start port is. I found what had happened was the PVC line that goes from the INSIDE of the filter to the rockerarm cover had fallen off. Dirt was being sucked through the open hole directly into the engine. There was also dust inside the intake boot. How the dumb thing got off is beyond me, but I will watch it from now on.

      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.”—
