@@volksdude1970 it’s internal. I checked for everything before opening it up. I had people telling me 5 thousand things it could be. Check the easy stuff first then if you don’t find it you’ll have to split the cases. Maybe post a video of the sound? I should have more videos on my TH-cam page showing what it was. Hopefully the videos are still up. TH-cam said they flagged a couple of them for music in the background 😤

This is the video that shows what it is th-cam.com/video/fFrgZX7uOl0/w-d-xo.htmlsi=cj2Aszs5OHs5nPyy

@@stelioskotso1304 no the starter clutch is attached to the crank. You’ll have to take the starter motor off. Along with everything else. Then split the cases

@@jamesa6272 send me please your e mail to send y few pics of my progress..and I hope y can help if I stuck.also y should have made a full video of the disassembly,it would be helpful for me...

Fucking hell @james your a hero for sharing this with me. Thanks a lot

Me to. I’m 5’2

Same here! Bike fits perfect!

@@joellaurin9007 yes it does. I just wish it would of came with a 750cc lol

Probably broke as I was in the middle of something. But thanks for being so observant. I walk on glass barefoot when I’m not working on the bike

Hmm. I didn’t have to loosen the steering shaft. I just pulled the rack forward with the rack bushings out. Gave me the room The shaft telescopes. You can pull it. Not sure if it will budge though. Also Maybe you have to open up the clamp alittle bit to get the shaft to slide in.

Cat test pipes 😉

Thanks man! Yup me too. My neighbor always had a fox body with the flow 40s when I was a kid.

Thank you Buddy!

It’s straight through with a core packed in fiberglass packing.

I definitely agree! It took me awhile to figure out what series it was that has that 90s sound. When you look at videos of flowmasters people just say “40 series”. Well there’s about 3 or 4 different series of 4 series. When I found out they were original 40s I bought them. It’s really hard to get a o/r H pipe now also. This one on this car is off of my 03 that I made fit.

@@jamesa6272 oh wow that’s crazy man.. also, the original 2 chamber flowmaster 40 series are the best mufflers ever produced hands down. You know what I love? When you go through the gears and you get it into 3rd gear, you can really hear that “wwwaaaaaaaa” sound I can’t explain it but I’m sure you know what I mean.. it sounds so good

@@JTM1987 Yeah man I know what ya talking about! They sounded even better on my 03 gt with the pi setup. Check those videos out of mine if you would like!

Sure. They are Emgo reverse cones. The plan is 40 slow and 125 main.

@@jamesa6272 where did you buy them from?

@@kerryrozon4166 someone on eBay was selling them

@@jamesa6272 Do you have a part number? There’s a whole bunch of different ones listed on EBay?

Hey. Yeah the starter bolts backed themselves out of the starter clutch. So when putting everything back together I saw that bolt was stripped from previous tear down of someone else. I just put thread locker on that bolt

@@jamesa6272 Do you have a website or some other social media your posting stuff to on this? I have a 87 450 and it has not been run in yrs. I know it needs carbs clean, and I saw oil moisture around the engine to cylinder. Was thinking maybe fork\dust seals to. Would be awesome to pick your brain on this bike.

@@1kzrider I don’t… just basically on here but if you have Facebook there is a rebel 450 forum

I could make this post private and give you the password and you can email me if you have any questions if you want

Jeez this video was when I was chasing the problem totally blind without knowing what it was but Yes you have to loosen the motor mounts and tilt the engine to get them out when you get them loose. Mine didn’t feel like they were going to snap though. It might feel like that because there is a rubber bushing /seal around them I think.

Hey. Thank you. Not many videos of them out there on TH-cam. I’m sorry I don’t have the dimensions because I took it apart. It was a simple build I just measured the the top of the engine and made the stand by those dimensions. You’re going to be working on the engine upside down. Measure the top of the engine and go from there. Your going to have to loosen the motor mounts to get the middle cylinder head bolts out. They are long and they will hit the frame. You’ll have to maneuver the engine to get the middle bolts out. Do you have the free manual? If not here it is: www.hanssnel.nl/hanssnel/Manuals/CMX450C%20Rebel%2086-87%20Service.pdf I got most of the parts I needed from cmsnl, Partzilla, and eBay. Cms/Partzilla both have part diagrams that are extremely helpful for the fix. You’ll need a nice place to work on it with a lot of light. Once you dig into it it’s pretty simple. This was the first motorcycle engine I ever split the cases on. When you have the engine on your stand… you can do what I did and get a ratchet strap and hook it to the engine and your ceiling / rafters and pull the top case up. Instead of prying on anything of the engine. That idea I had worked fantastic. I also watched a lot of videos on cb360/cb350 tear downs and rebuilds. They helped a lot. Specifically “Saturdays wrench” channel on his cb350 rebuild

@@jamesa6272 great advice. This is the first case crack. I have a Clymer and the service manual. I’m pretty good with instructions and I’ll just take it slow. I’m not sure yet what gaskets parts I need. I figured I’ll order once it’s apart. I have another bike for daily. I’ve got a garage with light and space. Here’s the bike last week after a carb rebuild. th-cam.com/video/ZzTe-pNtnrg/w-d-xo.htmlfeature=shared

@@sacksofphones I’m sure you’ll get it done. I literally went into that engine blind. Everyone had their own opinion on what the clunking was when I asked. No one suggested the starter clutch. I was able to find that out on my own. But it needed to be tore down to find the problem. Other then that your on a hamster wheel trying to chase down every possible thing it could be from the outside of the engine. There were no videos at all on TH-cam showing the internals of the engine when I did it.

Yes there is a chain for the oil pump: Here is the workshop manual Go to page 111 of this manual ( 8-11) and you’ll see it. Below are parts diagrams. I hope this helps you. www.hanssnel.nl/hanssnel/Manuals/CMX450C%20Rebel%2086-87%20Service.pdf Parts diagrams: www.partzilla.com/catalog/honda/motorcycle/1986/cmx450c-a-rebel-450 www.cmsnl.com/honda-cmx450c-rebel-1986-g-usa-california_model1055/partslist/

@@jamesa6272 do you have a phone # I have pictures I don’t think it’s a oil pump chain

Yeah this was when I first got it. I’m real impressed with it a year later. It’s a animal. Especially after removing some of the cat in the muffler. I’ve gotten pretty good and sharpening chains and that helps a whole lot. Def love this saw! Very happy with the purchase!

Hey. No it does not. Check to see if your tires are balanced.

​@@jamesa6272 the tyres ar new and balanced it seems to come from the engine. I can feel it through the foot pegs

@@Andzej52 has your engine ever been apart before? Maybe someone didn’t line up the counter balance weights correctly when they put the engine back together

I’m glad it helped !

You know it brother! No double guessing on what a shade tree mechanic did while your cruising at 60 mph

Same here, just found him because I started getting my 450 started again. But need to remove the carbs an was hoping to find a vid on how to do that 😂

Well. If your mechanically inclined and have the tools it could be an option to do it yourself. Problem is getting the parts. All the shops I called and went to said they wouldn’t even touch it. So your option may be the do it yourself. You’ll have to split the cases and see what’s going on if the starter clutch is your problem. Are you a member of the rebel forums? That would be a good place to start. Tell them your problems and see what they say the problem is.

No. Didn’t have to. If you get the 4 new rubber gaskets/orings on top for the 4 bolts it puts more pressure on the gasket

Original 40 series

Hmm the air box cover leaks you say? Have not thought about that. May be the reason for a stumble here and there when revving. I will check that out after I put carb rebuild kits in the carbs. Thanks man

Yours may not leak. But mine did. Fixing this solved my engine response tuning problem. Have fun!

@@edwardallan197 thanks for the advice! I’ll definitely check it out. My main problem is my oil smelling like gas. Including the crankcase. Going to replace the float needles and hopefully that will fix the problem. I installed new piston rings so I’m hoping the fumes or gas isn’t getting in that way. That’s basically the only problem. I’ve had this problem before I took the engine apart.

@@jamesa6272 Sounds good! Besides float needles, check your old vacuum petcock. A leak in the vacuum valve diaphram is another fuel to oil route..... that little rubber diaphram is very old. I had to drill out the rivets on mine, tap for little bolts, and change the diaphrams. The OEM petcock is too expensive. You have a GREAT durable engine, it should run perfect, start in the cold with brief choke.

@@edwardallan197 I definitely will check the petcock! I usually hate taking them apart

The valves you mean? No it was before I adjusted the valves.

@@jamesa6272 yea sorry I meant valves. That knocking doesn't sound good. It can be as simple as gas or timing, but it can also be something wrong internally like something warped.

@@MacrossGarage yeah. I’m trying to find out. The compression was 145 left cylinder. 165 on the right. So something is going on

@@jamesa6272 That sucks, might need to open it up.

Yeah it did.

Yeah it did but not unbearable. I mean it would probably bother your kids or wife if you took them out for a drive

Thanks man. Probably the only stock exhaust I like on a bike lol

@@jamesa6272 same!
