You didnt finish my quote. You can get anything to go fast its how you get there. Hence the push vehicle and 20 miles of track. Maybe a rocket too...


First gear with that gearing would be similar to third gear with stock gearing. A stock motor can take off in third gear no problem. Sluggish yes, but impossible no. The stock motor can't go 60 mph with any gearing. Drag increases exponentially with speed. The bike has the power to carry the weight of itself and rider, and also work against a certain amount of wind resistance. The wind resistance is too much at 60 mph and the stock motor simply can't do it. Not unless you ride with a very, very strong tailwind.
 
Probably a good thing, anyway; wouldn't you have ended up having to helicoil all the sparkplug holes if you kept that nonsense up for long? I think the later Rover version mighta gotten around some of that by changing metals...
 
Continuing with sending this thread totally astray: the local tractor-pulling organization used to have three or four guys running 215s in mini-rod pullers that ran around here alot. 215s have a nice high-pitched snarl with zoomie headerss on them.



Now it's all billet-laden SB and BB Chevies, seems like, and one guy with a totally nuts 4.3.



Sorry, now back to your regularly-scheduled program.
 
I'm sure it is, but even with my extra poundage working in my favor on a steep downhill, my bike doesn't want to go past the mid 8K range, rpm-wise. I have to think that's more breathing restriction than anything, since it runs like a top otherwise.
