Do I harm my Spyder's engine if I shift at higher RPMs?

[Easy Rider]

The question is - am I harming my engine by doing so?

Thank you for sharing your opinion!

NO.

And it is not just an "opinion".

Your engine is designed to operate safely up to the "red line" on the tach......which is about 7,500 I think.

Now....constantly running it near the red line might not be the best thing to do.

I try and do the same...

pps: I'm the "Low & Slow" Guy:
I normally shift at 2,000 to 2500 rpm.
Here's how it works out on the Speedmeter:

1st to 2nd: 13 mph
2nd to 3rd: 20 mph
3rd to 4th: 26 mph
4th to 5th: 32 mph
5th to 6th: 38 mph

The bike never shudders, lurches, judders or bogs: it just pulls smoothly! :2thumbs:

If I'm not in a hurry I try and use the same shift points. And if I stay blow 3k at cruse I consistently get 40/42 mpg, and, I can still read the lettering on the center rib of my rear tire. :2thumbs:

Right on! (Except redline is more like 8100, isn't it?)

The major point of having a computer-controlled engine AND TRANSMISSION is that it will not allow you to shift at any point that would cause damage to the hardware. Either UP or DOWN. You are only requesting a shift. The computer actually does the shift, but only when safe to do so.

So bang away, you are not hurting anything!

P.S. I shift the way Bob does. Except when I don't, and that's when I'm willing to splurge the fuel to have some fun! :yes:

8,100 in gear... 7,500 in neutral. :thumbup:

To shift or not to shift

I posted this about shift points in another earlier thread:

As long as you keep your oil changed, I see no reason to not wring it out once in awhile. In the old days this was known as the Italian tune-up, ya gotta blow the gunk out from the motor!

Not while you’re riding I hope, 2dogs?

Once in a while...

Open it up a bit. Keeping the RPM's below 4K ALL the time is not desirable according to several techs I talked to. Especially on low mile engines. I know rebuilding car engines they get a "lip" in the cylinder where the top of the rings stop in the cylinder. The tech said same thing happens in all engines. So once in a while when engine is hot I'll open it up and shift higher, cruise at 6K for a mile or two. He basically said if I ran at 4K or less all the time, that one time I need to open it up and get outta dodge the pistons reach a tad higher (microinches, but still) and the rings hit this lip and crack.

May or may be a thing, maybe someone here can confirm or deny. I like to open it up anyways, shift high around 5K once in a while, like getting on the highway. Holy cow this 1330 engine is awesome! :yes:

You don't need excuses to rev it up a bit: it's your bike! :thumbup:
BYW: that's all ancient history based upon technology long forgotten...

See if you can find out if the Spyder 1330 cylinders are Nik A Sil. I beleive they are. The likelyhood to wear a ridge is almost nil in that case.

Old school iron liners will form a ridge.

Much of this is based on ring technology.

Well I learned something! Love this forum! Showing my age worrying about ridges... :yes:

What ??? My engine doesn't have pistons and rings and valves and rods and bearings ???
