The value of a good tune up
I had a problem with one of my CB750's where I couldn't redline it in top gear on the street. (yea - I already know I should do that)
Previously I had geared the bike to bring down the R'rs on the highway and I was thinking I had gone a little overboard on the gearing and that was the reason why I couldn't get more than 7500rpm's out of it in top gear. The bike would redline in all gears except 5th and ran pretty decent.
So I spent most of this past Saturday going through the bike and giving it a good tune up. It was due for an oil change anyways so I also changed the plugs, set the valve lash and cam chain and checked the timing. (I have electronic ignition in it)
After I got done doing the tuneup, I tested the bike on the highway. Now the bike will easily redline in 5th. I'm now thinking about throwing more gears at it to reduce the R'rs even more.
I guess the lesson learned here is even if the bike seems to be running decent - it still may need to have a schedule tune up.
