Yup. Invest your money in suspension improvements and you'll see a lot more performance than you will get from an extra HP (+ noise) up near red line.

I've had a continuous string of Honda XRs since they first came out in 1979. Other than opening up the intake, I avoided engine modifications. High compression & hot cams might buy a little power, but always at the expense of reliability.

My biggest complaints on the 650L: Too top heavy, and a flexy front end.

Things I liked: Very reliable and turns quickly in the tight stuff.

Thank you for the recommendation, Ono. I will add that tire to my short list of tires I will experiment with in the future.

Yes.

If you're in there doing a rebuild, might as well replace the chain and tensioner. I've seen too many people not replace the chain and tensioner regret it later when their freshly rebuilt motor dumps the chain and they have to tear the motor apart and rebuild it again a few thousand miles (or less) later.

Pricey and annoying.

As an update, I had the cylinder bored and honed but had a minor set back when I washed the cylinder and minor rust appeared the nest day (I forgot to oil it). I removed the minor surface rust but there are light grey spots present. The machinist said that they shouldn't cause any damage but I'm not taking any chances and having him run the hone tool through it.

Timing Chain

The way I check to see if the cam chain is stretched is to look at the cam sprocket marks. If the marks line up with the edge of the head the chain is OK. If the marks are a little OFF this way or that then the chain is stretched and needs replacement.

OE or aftermarket? A chain is a chain.
