it'd hit 95 in 4th

laying on tank
sitting up was an automatic drop to 90

Well, Slavy, since you obviously love this argument so much, I'll keep it going just for you.  

Do you pin your car in top gear at normal speeds? Or do you downshift? Higher gears are not only for going fast, but for saving gas and (sometimes) making it easier on the engine. If you really need acceleration and you've got a hill, then grab a lower gear. I went up a grade today in fifth. Seemed a little easier in fourth though. Still, does it really matter that much?It's not like you're lugging at 3500-4000 or more rpm, right? Do you really need to be able to do everything in top gear? Do bicyclists use top gear for everything? If he does, he is either one tough cookie, or his gearing is a bit short.

Is it better to let a 3.5 inch stroke engine rev to 5k all the time or to hold it at high loads? It seems that we're in between a rock and a hard spot. Drag it too low and you lug it because it's a poor little one-lunger. Rev it, and you have to think, "Isn't that hard on it?"

Now, isn't it true that the forces on an engine increase exponentially with engine speed or something like that? Or am I getting things mixed up?

So, for our thumper, wouldn't revving be a bit worse than loading? Anybody wore out a Savage by loading? How about by high revving? Always reading here about somebody warning that Savages use oil when they're run fast on the highway. Is this more from work/load or from revving?

Slavy, If you can go just as fast and save gas and make things easier on your motor, would you do it?

Now, I've got twisties and hills, so I can't say for sure how I would like taller gearing. You gotta have some revs for twisties and hills. I'm going to guess I'll like the bigger tire when I put it on, but I'm not sure about a 17/43 or anything like that.

How big a crankshaft journal does one need before he decides it's better not to rev it like a Kawasaki Ninja. How long a stroke does one need before he can load it down without fearing that he's ruining his crank bearings? Can a big-stroked thumper win? Or is she hopelessly caught between conflicting forces: lugging, which tries to beat her to death, and revving, which tries to sling her off into pieces?

Reminds me of Bill, he does.....

Here's an interesting article:

Haven't studied it really well yet.

If the header pipe had a bigger ID. would that fix it ?

don't look at the valve spec's, I don't think you can take it.

Yeah, I know. But, nobody said we wanted to design a new head, just do the best with what we got........

yes a Taller gear would have been better in some ways, and you always have 4
th for passing, but we got what we got, and that's all what we got, so what the hell, gotta live with it
