I rode a friends Ambassador that was sporting an old high mileage Eldo
850 engine driving the the stock Ambo gearing thru the Amdo 4 speed
trans. The difference is huge the 850 has a LOT stronger low end and mid
range and still has an edge on top as well. The 750 could well use the 5
speed gear box. I think the question was POWER difference and the 850
has a big edge, the engine has an edge in power and the edge is further
enhanced by the 5 speed.
Don't forget the OVERALL gearing of the 4 speed Ambassador is LOWER,not
higher so it takes a bit more power (RATE of doing work) to pull the
higher overall gearing of the Eldorado.

| With regard to bore & stroke changes to engine output, an increase in stroke will increase low end torque; more torque but at a lower rpm. An increase in bore will yield more hp by generating more torque without shifting the rpm of the torque peak downward. My experience with riding loop frames is a half hour ride on a well used Ambo with a Velorex chair & 200 lb. passenger, and a 50 mile ride I took last Tuesday night on an Eldo with 9000 original miles on the clock. My conclusion is they have comparable grunt, any advantage with the Eldo was due to the flexibility afforded by the 5 speed gearbox. Both are great rides! If you want either of these machines to make power, get the rpms up above 4000. The bore to stroke ratio on both these machines is way oversquare (bore larger than stroke) and they like to rev. The perfect primary balance afforded by the 90 deg. V configuation keeps the vibes at bay and things seem perfectly happy spinning up to amazing speeds. Just my 2 cents worth. _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp |
