thats what i thought too but to play it safe im just listing everything
everyones saying something else...what about 69 and 77 and all that
?
why a 48? cus the only 66 i ever got, by accident, was a lemon from the word go, whereas all 48's have been bulletproof from the box when left alone. having lots of them means i can swap parts and play around without getting seriously
the slant head kept warping and leaking cus theyre too thin under the plug, (all of the ones ive seen are just as thin but noone else complains about it?) powerwise i didnt really notice anything, and its been the only HT ive siezed! it surged, it wouldnt wind out nicely, it wouldnt tune up, otherwise great
i only got to work without pedalling once in that week until my new 48 arrived. home? ha ha. it was only a 5km ride!
after that, do you think id really want to order a 66?
i might think theyre better if the stroke/bore was closer to square...you get proportionally more torque with increases in crankpin offset therfore leverage (torque is a measurement of leverage or turning force) than you do by increasing bore sizes.
long skinny makes slow torque (diesels?) whilst short n wide makes for fast RPM... cbr250?
plus the 66 uses the same little end bearing as a 48...so it transfers more pressure than the 48 does. more load, more inclined to failure.
i do have an extremely biased opinion
dont listen to me!

i can also make tuned pipes that do what theyre meant to do. no lack of torque in my area
instead of straining the things, they tend to last longer than ever!
i respect that due to circumstances some people cant fit a pipe that works and must find alternatives
