Honda 450r sat, now won't start

Recommended Posts

My older brother bought a 2005 450r (kick start) new in late 2006. He rode it for one year (maybe 5 times) and then it sat. Since he doesn't want it, I want to get it running. It won't start though. It has some type of plastic screw thing on a line (maybe going to carb, not sure) that my wife was turning. Not sure what that did. What should I check/clean to do to get it running? Thanks guys.

thats the idle adjustment, you probally need to put the carb off and take it apart and clean the piss outta it. then i would reassemble put new gas in it and it should fire off. after that change the oil in both sides of the engine and let it rip

Get an owner's and a service manual!!!

What he said, and a valve adjustment. Do not try to start it with the old gas in the tank, you will just make things worse!

This Honda is unique among 4-strokes, because the engine and transmission oils are seperated! Read this: http://www.thumpertalk.com/forum/showthread.php?t=982482

definately take the carb apart and clean it out. its not nearly as bad as it seems. a can of brake cleaner, an air gun, and i bet it'll fire right up.

Just spraying a bunch of cleaner around all over the place won't do it. It is always the idle jet that gets crudded up when stale gas dries up in a carb, so be sure you clean it, or better yet they are cheap so just replace it.

which is exactly what i meant when i mentioned an air gun. a can of compressed air will even work. you dont need a manual, its really not that bad. pull the rear fenders, gas tank, and air box. turn the gas off first to the tank and crack the screw loose on the side of the carb to drain the gas inside the bowl (bottom cover). you dont have to take the cables off the carb. pull it out and twist it enough to get to the top and bottom of carb. pull the needle and clean out the passages. pull the bottom cover off and remove the float to get to the jets. remove them and spray them out, spray the passages in the carb. blow it out with air. put it all back together.

just becareful while youre doing it and dont drop anything. lay everything on a rag in order if ya have to. then get used to doing this cause its a very common thing (at least it is for me running around on these dirty coal banks in PA). 2 or 3 times and you'll just complain cause ya have to take so much stuff off to get to the carb lol.

hope this helps.

If you find that there is a black contaminant in the fuel when you drain the float bowl, it will be time to replace the fuel line also. This 10% ethanol in the fuel eats up non-compatible rubber fairly quick reducing it to a fine black sandy looking crud in the float bowl. Of course this will plug your jets and orifices in a heart beat.

i've also had a bad batch of gas destroy the filter inside my gas tank last year. that same batch destoyed one of my carbs too. it was in my quad for a couple days before all this happened. guessing it was ethanol? ran fine in the orher 2 quads though.... weird.

Thanks a ton guys for the responses. Been so busy with planting and baling hay haven't even had a chance to look at it. Got a manual downloaded and found where it talks about the carb. Would I need to get like a carb rebuild kit?

I would remove the carb, open the float bowl, remove the jets, and let the carb and jet soak in one of the gallon cans of carburetor cleaner they sell at the parts stores. After soaking for a day or two, blow it our with compressed air and look through the jets to make sure they are not obstructed. If the float bowl o-ring is still in good shape, I would go ahead and reassemble the carburetor and reinstall it along with a new fuel line. Give it a try then. All you will get in a rebuild kit is a new fuel inlet needle valve, float (maybe) and gaskets/o-rings.

I personally wouldn't try cleaning carb on qaud. If you goin to clean it out u need to COMPLETLY take it apart. Not just jets. You will still have junk in other valves of carb. Take your time and take everything apart so u get it right the first time. I would also reccomend taking pump apart. Metal rod of pump known for rusting (as said above) ethonal eats up/ hold moisture in carb.

Once you clean everything up and make sure of spark don't be afraid of a good pull start if you get tired of kicking...lol

Have fun

Just want to say thanks a ton guys. Finally was able to work on it today. Got what little old gas was left drained and removed the carb. Cleaned it up and put new fuel in it. Fired on the first kick after not running in probably 3 or 4 years.

      Hi all!

       I've got an issue, one of many when it comes to bikes. I searched throughout all the pages I could find pertaining to my situation and couldn't find very much useful information.
      So the issue is, the bike has no electric start.... until it's hot enough to melt steel that is. It will bump start first time every time. But I can sit and crank the starter over for ever and it'll never start until the charger is bumped up past 200 amps. Not good.

       The story so far,
      Got the bike for 1k cash. Guy said it has no spark and no second gear. This particular guy also only ever rode newer crotch rockets. Brought it home pulled the choke, attached battery charger and she fired right up. Ran like absolute crap, but oh well I figure it's an older bike with only 10k miles so it probably needs a good carb cleaning. Took the carb apart and didn't know I messed something up until way later(didn't tighten down main jet). Oh well she runs well enough if I can get her started. Moved from California to Oklahoma. Eventually found the money to fix 2nd gear, and as I am a certified Honda small engine technician apprentice I figured it would be no big deal. Completely tore down engine to it's roots replaced 2nd, and 5th gear(because 5th gear connects to 2nd on the countershaft) dogs were worn pretty badly on both. The engine looked quite good compared to most others I've seen. Put the engine back together as per the service manual. Did all the right steps including loosening the banjo bolts to test for proper oil pressure. I even tore apart the electric starter to clean the contacts and the brushes and replace the dielectric grease. Adjusted the valves as per the service manual, replaced all gaskets, o-rings, seals, and oil filter.
       Finally after about a month of waiting on parts and reassembly I get to start her, only she doesn't. Electric start is still giving me the same issues I've always had. So I replaced the Ignition coil, CDI box, and put a new battery in, plus the starter motor rebuild. Nothing. Still cranks forever. I said what the heck and tried to push it slightly down hill and bump start it, and voila... fired right up! Once she gets hot enough and the stator charges the battery enough it'll electric start... sometimes.
       So I looked towards ignition, used a tool called ignition mate. Pretty awesome tool if you can afford it. Well while cranking the ignition mate reads the spark plug is getting 1-4kw of "spark" every cycle, well it only fires after getting up past 5kw sometimes 6-8kw. And sometimes the ignition would be intermittent as in it wouldn't give any spark at all. I cycle the ignition and it seems to soft reset the bike as it will usually give it back spark. I tested this with the new and old CDI box, the old one would never spark. Ever. So I threw it in the trash. A month later I stil l can't figure it out.
       Is there something I'm missing?

      TL;DR
      Bike won't start using electric start only bump start before and after engine rebuild
      Electric start works after pushing the starter past about 200 cold cranking amps or when hot.

      30 years ago I sold my beloved 1985 CR500. I was young and needed money for a car. I had a lot of fun on that bike and some of the best dirt bike memories were made on it. Out of all the bikes I've owned it's the only one I regret selling. I've had opportunities to buy a 85 cr500 before but never pulled the trigger figuring leave the fond memories in the past. Well today I couldn't pass up the bike any longer. I found me a nice project bike to take up some free winter time. The bike is all there and it runs but most importantly it was cheap. Not the prettiest but it's mine. With lots of money and time it shall be returned to it's former glory and be ready to make some new memories.

      Has anybody purchased/used one of these Arrowhead IHA6017 cdi boxes??  I tried 2 different ones of these on a 1987 and 1994 XR200R, and the bikes won't even start.  Bikes just pop and backfire, had to put the old cdi's back on.  I noticed when I ordered the boxes they stated "advance ignition curves" in the specs.  The box is also much bigger than the stocker and won't fit in the rubber mount.  I didn't mess with moving around the timing to try and get these to work....I just sent them back.
