Re: Eric Cope smashes 127mph at Elvington on full-bodied Taylor Tuned Lambretta 250cc

I’m sure Darrell knows +\- 1 mph! [emoji6] He does, I'm just stimulating debate... :lol: :lol: Well if we’re talking about traditional group 6 with vega legshields, I don’t think there’d be much difference (could even be slower) In a good streamliner, I’d guess 150+ Dunno - interesting stuff [emoji...

https://www.scooterotica.org/forum/viewtopic.php?f=7&t=29198&hilit=dynabike That was a great discussion. I love that you quietly gather masses of (real world) data to calibrate the software, use the software to indicate the required engine characteristics, develop the engine, and then knock it out ...

Regarding flex at rpm, there is a very old 2-bearing in-line 4 engine that flexes like nobodies business. When people tri...

Re: Main bearing alignment?

I've never had to check, but I understand that if alignment was likely to be out, due to extensive welding, then axial alignment would need it. Unless I pulled in a favour with somebody that works in a machine shop with XYZ inspection facilities, I suppose the crankcase/magneto flange assembly coul...

Main bearing alignment?
