I'm building a loop frame Guzzi from parts. I want to replace the 4-speed that came with the parts bike with a 5-speed.
Which 5-speeds will fit?
There is one on eBay from a 1999 V11 that looks like it might fit? Or am I limited to Loop and Tonti frame transmissions?
Thanks
-
all 5 speeds fit, the V11(Sport/Lemans) is a 6 speed so no. If you saw a V11 Cali (EV,Bassa etc) yes they are 5 speed.

All of the 5 spds. will bolt to the engine and the frame as far as I know. However, the Eldo 5 spd. rear cover was different than later ones. Two differences are the angle of the speedometer drive and a cast in "carrier" for the pedal-to-transmission shift shaft. There are workarounds for both, but it's easier just to swap on an Eldo rear cover. May not matter if you're doing something "custom".
What rear drive are you using? If you plan to use the Ambo 8/35 rear drive with the 5 spd. be prepared for lots of clutch slipping to get moving. Gearing will be quite "tall". The 5 spd. should really be paired with an Eldo 8/37 rear drive or later 7/33.

The 4 speed had the shifting spring on the outside (that never broke) and the 5 speed had the shift spring on the inside that in my experience did break. A few bucks for the spring and big bucks in labor to change.
It has been awhile for me so feel free to comment or correct.

You're right on! The 4 spd. return spring is under a small triangular cover on the back of the transmission rear cover. Even if the 4 spd. spring does break, it takes about an hour to replace.

Mayor BBQ, Thanks, but I'd like to find a newer / lower mileage xmission. But I would like to have that entire bike. But i have no room for it. I could find room for the engine/xmission though.
I'm not sure of the ratio but the rear drive is looks like to ones used on a Tonti frame machine as opposed to a loop frame. I will check the ratio. Very helpful information!
Thanks for all the great info

"Sometimes" you will find the ratio stamped on the housing above where the input shaft bearing would be.

There are three or four final drive ratios possible in identical-looking casings. Really the only ways to tell are to count teeth, count pinion turns/ring turns, or look at the etched markings on the gearset. I'd elect for counting turns if the rear drive is assembled.
