CB500/550 / Rocker Housing - Stuck??
« Last post by Mike_Berkshire on Today at 06:13:32 PM »
Following the successful (final) removal of the seized oil filter bolt and the seized engine hanger I have got the engine out and on the workbench. Sump, breather cover, cam end covers removed. Rocker cover/assembly screws and bolts all removed thanks to the impact driver and JIS bits recommended by this forum. However, the rocker cover/assembly wont lift off. I have given it a few taps with the soft mallet and checked for hidden bolts but I cant see anything I have missed. There is a clear gap at the front of the engine between the cover and the head but at the back (intake side) there is no gap at all. It looks as if there are a couple of locating dowels on the back edge which if steel may have corroded and stuck fast. Is there a bolt/screw I may have missed and what are the thoughts about the locating dowels sticking; does this happen and if so is there a remedy? I have attached an aerial view in case there is something obvious to the experts. Many thanks. Mike

Other Bikes / Re: BMW R80

Hi Dave,
I've had an R65 many years ago and an R100 RT Classic more recently. Engines are virtually bomb-proof - if servicing has not been skimped.  Depending on the year, gearboxes can be troublesome. Not sure of change points but early bikes had a circlip holding a bearing in place.  BM accountants decided it wasn't necessary as the bearing couldn't come off the shaft!  True, BUT it could move and cause bearing failure.  Saved them a few pence on each bike. Many replaced under warranty, so the circlip was refitted and the groove re-introduced.  My 95 R100 had the groove - a friends 88 R80 didn't.  I made a rig for the lathe to re-machine the groove in the hardened shaft with a thin grinding disc in the dremel.  All gearboxes can suffer from gearchange spring failure which leaves you in whichever gear you were in when it failed.  A few special tools needed to strip the box and the casing has to be heated to get everything out.  I made the tools and gave them to the mate with the R80 but could beg them back if you needed them.

I fitted this one 15420-300-020P a Honda part iirc 17 mm head listed for the CBX1000 that fits the 500/550 etc

I think it differs from the original as it has a bigger bolt head - not sure if its Chromed or something like BZP.
Some of the cheaper aftermarket ones do not have as many holes in the center section.

It's so frustrating Ted, I've asked yet again today if they can confirm which speedo cable type I need for a cb550, the reply avoided answering the question.  I'm fairly certain I know having taken mine off but confirmation would be great so it's over to Roo to answer it for me.

CB500/550 / Re: Plugs fouling at idle
« Last post by Johnwebley on Today at 05:19:06 PM »
Could I suggest something I do,

Take the bike for a run   about 15 to 20 miles  get it nice and warm
When home, keep the engine running, put on centre stand

Get your long screw driver

Now ,turn one airscrew a quarter turn out,
Check what happens, blip the throttle, OK?

If it struggles,turn to previous settings

But if its OK,do another, repeat, and check

Remember, Modern fuel is different than 50years ago,

It might like a leaner tickover

Good point John, most folk overtighten canister oil filter by hand often needing a chain grip tool to remove them.

I try to use the lower torque reading given or just by feel as the O ring becomes compressed.

Unfortunately I haven't been riding like in the past: looooong stretches >130km/h uninterupted on motorways. It was always great how well the engine responded afterwards.
