Recent purchase, whats next? - Classico_imp - 03-20-2022
My “new” 15 CB 1100 EX has 44000 miles and comes with no documented maintenance although I’ve been told by the seller that it’s been maintained by an Honda dealer by its first owner up to 40k mikes.
The bike is in very good shape aesthecally and the engine purrs nicely.
What should I plan to do on my first service?
Are 44k mikes cause of concern?
RE: Recent purchase, whats next? - the Ferret - 03-20-2022
NO, 44K miles is not a concern. Empty Sea has about 50K, I have 64K on mine, I think Cormanus has 75K on his, and I think 2 of the members have over 100K without issues.
I would change the oil and filter, examine the air cleaner, check the tire pressures and check chain tension and adjust if necessary. Other than that ...ride.

Since you don’t have the maintenance records, I’d also recommend replacing the brake and clutch fluid. Take a peek at the brake pads as well.

Is it possible to find out from the seller where it was serviced? Then you should be able to see the actual service done. I would be most concerned when the valves were last adjusted or inspected.

PO is trying to gather that info, puzzles me that he havent done so during his 3 yrs ownership!
I understand that valves’ inspection take considerable time (and money!) Wonder if an expert mech could hear valvetrain and judge without taking cams et al out
Take note of all other recommendations too, thank you all, gentlemen

The cams do not have to come out to check clearance. They do have to come out to adjust.

Classico some members have collected their valve adjustment values and mileage over the years in this thread which can give you an idea about what to do about your valves;

we have no reports of any valve related incidents in the past and this engine is under stressed, so good thoughts on the adjustment but no reason to worry, if the service has been carried out by honda it would have been done by them, maybe have a very close look at the valve cover bolts and look for signs of spanner marks on the hex flats in the "undo direction", these bolts require very low torque values but still.....
Oh and be advised about NOT using oil filters with a hex nut spotwelded on the top, they have failed and spilled oil mid-stream on the road, good to know.

Thanks Lord Popgun and Max, very useful info!

If the valve adjustment has gotten too tight, there is nothing to hear. It is common for clearances to tighten up over time as the valves close millions of times against the valve seats. When a valve closes, it transfers heat to the cylinder head. If clearances are tight enough to prevent the valve from closing fully, damage to the valve is possible.
