Get a Clymer or Haynes manual for your bike. Synthetic probably would not cause problems but isn't necessary either. Stick with the dino juice and routine maintenance and you'll be finde...

a quick search on the net (amazon, etc.) didn't turn up a haynes manual for your particular motorcycle, but 10 seconds on google (search perameters: "how to change motorcycle oil") turned up these useful links...



1



2



3 (here on the MO servers)



4



5



if nothing else, see if there is a section in the owner's manual (did you get that from the previous owner?) which covers this very basic and necessary process.

cheers :)

What would be the point in switiching to synthetic? It's just more money for a bike that will be just fine on dino oil.

The only possible reason would be if you're in a very hot climate and you're having a problem with overheating. My air-cooled HD consistently runs 50+ degrees cooler with synthetic oil than with mineral oil.

Yes, that is a concern I currently have. When the temps get in to the 70's I noticed that the clutch pull becomes very rough. I am not sure if that's a indication for a hot engine or not. My bike doesn't have a temp guage and it is air cooled.

It would be kinda cool to have the oil in the bike be worth more than the bike itself.

Don't put synthetic in this bike. The gaskets and seals in the engine are 25 years old. If you put synthetic oil in it, it'll leak oil like a sieve. I don't think synthetic causes leaks, but it will find its way through places that regular oil won't, especially with old seals.



I had a '79 400 Hawk that I rode for years and just put regular oil in it. It's still running for the guy who bought it. The 450T will run great with regular oil.



Get a manual to change the oil. It's not hard to do, but these bikes don't have spin-on filters so the manual will give you some guidance the first time.

fumanchu 04-28-2007 10:05 AM

Re: 1982 Honda CB450T-Hawk Oil Question
 
...links 4 and 5 have to do with your synthetic vs. dino dilemma. (i do agree with the others about just running decent dino oil in your rig and changing it at regular intervals, however.)

cheers :)

Re: 1982 Honda CB450T-Hawk Oil Question
 
Do you mean ambient temperature at 70 Farenheit, or engine temperature at 70 Celsuis? Because if it's giving you problems at 70 ambient I'd say it isn't the weather causing the problem.



You can get a cheapo IR point thermometer at pep boys. It will tell you the temperature of anything you point it at. Useful for finding hot spots on engines, tire temps, surface temps in general. Could come in handy for you.

it's quite a common old honda's problem. when the motor is hot, the inner ally clutch hub expands and rubs against tired and deformed clutch springs. Tear it open, get the springs out, fit new ones (cheap) and while there, enlarge with a dremel bit the internal diameter of the spring cavities.

Re: 1982 Honda CB450T-Hawk Oil Question
 
I am finding that Shell ROTELLA T SAE 15W-40 seems like good choice for a dino oil. Any one have any experience with it?

nolaandy 04-28-2007 03:35 PM

Re: 1982 Honda CB450T-Hawk Oil Question
 
For a number of reasons synthetic is not a good choice for this bike. Rotella T 15W-40 is a good choice, as are all the diesel-specific non-synthetics. You can also look for Delo or Delvac, but Rotella is much easier to find.



Synthetics will indeed find leaks where currently there are none.

Better yet: take the springs that are in there - use a screwdriver between each coil (or some other means) to "expand" the springs. Cover a cookiesheet with foil and then "bake" them at 350deg F for 4 hours in your oven to re-anneal them (it goes without saying to clean them thoroughly if you'd like to use the oven again for food).



Whilst it's apart, take the clutch STEELS (noting which order they came apart) and toss 'em down on a flat sidewalk. Use your foot to move them around, "scuffing" the surface of each side. The coarser the better. Don't overdo it, just get the surface good and scratched-up. Clean these thoroughly, re-assemble with clean engine oil in the reverse order, with your newly-annealed springs.



Button back up with a thin bead of Yamabond or Hondabond (hylomar) sealant.



There you have it - Zero Dollar clutch rebuild. (you should already have the hylomar in your toolbox. WhaAAAT? You say you DON'T? Why not?)

If you are just now getting around to changing it (for the first time since 1982?), why bother? The old oil is probably barely broken in.

Re: 1982 Honda CB450T-Hawk Oil Question
 
You think that I'm joking about that technique?



It seems to be pretty common amongst moto-cross racers; it's been related to me by three different people (but only one suggested the spring-annealing trick).



I admit, I have yet to actually try it. BUT, I fully-intend to use it next time I have a bike with a "soft clutch". (actually, I have one that's softening-up a bit right now, and will likely employ this method early this summer)



I'd say it's no less-valid than enlarging the openings around the pressure-plate springs. If Honda had wanted them bigger, they'd have made them so at the Factory, right?



I'll report-back on my success (or lack therof) soon enough.







P.S. Those of you who change your own tyres: If you don't have a Mojo-Lever tyre bar, WHY THE HELL DON'T YOU?!!!! That thing is FAN-tastic!

Try talking to these MOrons like this
 
Try telling them a third time.. You see these MOrons don't like to use logic, facts and data. You see they are avid Faux News viewers ... So use a little fear like "if you don't replace those deformed clutch springs she'll blow" these low life W loving GTPB hicks love that kind of talk..Best to add some derogatory comments about liberals, engineers and Honda bikes in general just to seal the deal.

For a Republican, you sure worry about what this motorcycle forum says about liberals a lot.



As the guy who chaired his district's Democratic Primaries, I haven't felt particularly insulted, and frankly I think most insults Democrats get are deserved. Trying to count votes at the primary was like herding cats. Every other person there wanted to count as well; they were all better counters than each other, some were professionals, maybe all of them, it was hard to keep track.

I don't know what I am
 
Really then you probably know my wife who is one of your counter parts on the Republican side. Yes I am a Republican just not a W neo-con reckless fiscal spender Republican. I state my positions then you decide.
[*] Pro life
[*] Rifles and shotguns are ok to own no restrictions but I would ban assault rifles and hand guns
[*] Fiscal conservative like a balanced budget
[*] gays should have the right to get married
[*] Against racial quotas but think blacks should get retribution for slavery in the form of no down payment liw interest home loans and free college tuition for life.
[*]Strong military but we should not play the world's policeman.
[*]Need a national energy policy and program to get us off all foreign oil by 2020.
[*]Need a radical simplified tax policy. Flat tax with the first 35,000 not taxed. i.e. if you make less than 35,000 you pay no tax. However if you make a million you pay 350,000 dollars no exemptions or deductions..
[*]Shrink the size of the Federal Government. Don't need 4 FDA bureaucrats for every farmer
[*]Catch and kill terrorists using covert hunt them down kill them techniques. Rather than invade a country style..

Technically if you make a million your first 35,000 is tax free..

My GSX1100G is especially touchy on the oil it tolerates. This shows up in how easily the tranny shifts. I used Mobil1 for years because it gave the best tranny performance. It'd go 4-5K with smooth shifting. However recently the cost of Mobil1 went from $4 per quart to $7.50 for the 15-40. I went to RotellaT and the bike shifts just fine for the 3-4K I go between changes.



So, if you're worried about seal problems (no comments about blown seals, fur seals or harp seals please) go with RotellaT. $9.97 a gallon at Autozone.

You know. it's really past time that the stupid moderating function got disabled. Some @sshole has been moderating all over the place the past week or so. If someone doesn't have to balls to state directly what his disagreement is then the coward should just go and f*ck himself.

I run it in my '76 CB750F. No problems, no new oil leaks. Clutch seems quieter.



Good stuff as far as I'm concerned and it's pretty cheap too.
