Im starting to restore my 450 so i decided to start a thread its not in bad shape just a few things i want to fix such as

-Oil Leaks
--Valve Cover Gasket
--O-Ring Around Tach Cable
--O-Ring and Oil Seal Around Shifter Shaft
--Clutch Push Rod Oil Seal
-Replace Starter Button/Kill Switch
-Replace Signal Unit Generator
-New Rear Brakes
-New Muffler(s)
-Repaint
-Replace Rear Turn Signal Lens(maybe front)
-New Braided Brake Line
-Re-Upholstery the Seat
-Headlight Fly Screen
-Replace Shocks
I hope im not forgetting anything anyway, i starting with the oil leak father-in-law is pretty good about motors and bikes and he thinks my main leak is coming from my valve cover gasket so im replacing that and we also noticed oil from the shifter shaft so i will replace the o-ring there. im also going to replace the o ring around the tach cable. the question i have is while we have the valve cover off we are going to make sure the valves are within specs along with the cam chain. anything else we can look at while we have it open. also since im ordering those other o-rings are there any other cheap o-rings i could replace while im at it to eliminate oil leaks, bike sat for a while before we got our hands on it and im sure these little orings just got hard. the bike only has 55xx miles on it, but o rings are cheap so while im at it i want to replace them. thanks for any help

Cool, good to see your project thread up

Will follow along for sure!

Maybe do the clutch pushrod oil seal as well?

[TyFerris]

call me a rookie or what not but is that easy to get to? right on the outside of the motor?

[cowboyup3371]

Look behind your sprocket cover

[TyFerris]

behind the sprocket cover for the clutch push rod? or what?

[cowboyup3371]

Yes, for the push rod

[pete]

Number 22:



And yes behind the sprocket cover just like Cowboy said

[TyFerris]

Okay thank you cowboy and pete for your help will order that as well... got a clymers manual on the way as well so hopefully i can solve this oil leak. is that push rod seal fairly painless and easy to replace?

[pete]

Mixed reports on that one

I found it incredibly easy but I had the crankcases apart...

A common method is to put a self tapping screw either side of the pushrod so you can get a grip to pull the seal out.

Hopefully being an '82 you'll have the two part pushrod and you can slide the pushrod out which will make it much easier.

Oh, and jump on eBay and look for a reproduction factory manual from a seller called eClassic bike or similar. I scored mine for about $US30 plus shipping and it included all the addendums and things as well.

[cowboyup3371]

I don't have the best of pictures but it's a pain to get that seal out if you can't drill a screw into it past the thin sheet of metal (I couldn't). Just don't go too far or you'll puncture the casing. Once you get the screws in you should be able to pull the old one out. I'll try to find a posting of mine later and you can see some oif it

[TyFerris]

okay thank you

[TyFerris]

so just got my clymers manual in the mail and it talks about tappets and shims for adjusting the valves? i talked to my father in law and hes clueless. he said that sounds nothing like any motor he has done can anyone explain or help at all?

[TyFerris]

also how do i take the round valve side covers off my clymers manual says for the 400 and 425 un screw the screws... the 450 doesnt have screws lol

[cowboyup3371]

I believe the ones on your bike just pop off but someone else can speak to that.

Do a search on valve adjustments here and look on Basscliff's site for the tutorial to swap out the shims. Send Steve (name and username) an email to get his valve spreadsheet (you'll need it).
