While spending time fabricating stuff for my Eldo 1200 motor. I'm trying to figure what transmission I have bolted up on my Eldo. I have a 4 speed and 5 speed that came from Loop parts bike. I have a G5 5 speed from another parts bike. Th eplan is to take apart the G5 trans, clean, fix, replace or trash it. I recently learned to utilize the G5 trans I would need the Eldo 5 speed end case. Curious if a 4 speed end case/piece would work. I also recently learned to run the G5 rear end, I would need a 2mm space to properly align it on an Eldo swingarm. I also have a spare Tonti swing arm to switch if necessary .
Thanks in advance for any insight.

  If my memory serves me , the clutch cable came in from the other side for the 4 speed end cover .  Peter

You can use any 5 speed as-is, but you'd need "custom" shift linkage. You'd need the Eldo rear cover if you want to use the original footpegs, pedal and shift shaft. Also, the speedometer drive on the Eldo rear cover is angled outward from the center of the bike and the Tonti drive is angled inward. A 4 spd rear cover will not work.

If you have a Tonti swingarm, use that with the G5 rear drive.

As of right now I'm not using the stock footpegs, brake or shifter. Fabricating  them. I'm using a design that Scudman on advrider used on his Eldo "Fattie". Right now I have the Fuel , Fuel Filter  and Regulator installed. I'm running Calvin/Norge throttle bodies. I didn't realize that they are different from earlier California's. I saw your pictures on Facebook. I've alway been a solution looking for problem kinda guy.  I can't believe how much I complicate everything. I saw your airbox/oil breather setups. Those are a work of art. Just trying to get some momentum going. I have a gas tank issue. 2 semi usables tanks. I found a tank . I'm waiting on it because I need precise answers rather than educated guesses. Thanks for info.

As others have said above speedometer Drive was moved from the outside of closest to the foot Peg to the inside closest to the battery in doing so it's probably a rotating the opposite direction if that's the case your instruments won't read correctly again when they move the speedometer drive to the towards the center of the transmission I believe the speedometer drive gear was also moved to the other side of the  cover case so now it rotates backwards compared to what you have.

With all due respect. I think the speedo drive is the same direction on both. I think all they did was tilt it to one side or the other. At least one of my Loop 5 speeds has a flat spot where the drive could have been drilled.

Rotates the same direction, the angle is just different .

Yep, internet threads get (wrong)answers to questions that were never asked.
Maybe single point yes/no questions might help stop ?
So Iíll answer the question in the title

Re: Can you see the differences between an Eldo 5 speed vs an Ambo 4 speed?

YES, CHALK & CHEESE

RE 4 speed cases, 5 speed internals & cover
You might enjoy reading about the Tallio Rosso (red frame), the pre production V7 sport that basically did that, lots of pics on net.
Parts used will not be available but anything can be made
Also see Charlieís pix on thisoldtractor showing how late 4 speed cases were changed to allow drilling/tapping for the 5 speed cover

Re Gearboxes and final drives, seriously easy to fit any but do bear one word in mind óRatios
For instance a 4 speed with a 7/33 is pretty low gearing
5 speed with 7/33 was factory spec for most tontis although 5spd loops used 8/35
I have my choices but is easy maths, compare with top gear on 6 speed / carc to see what your motor will be doing with new choice
Swapping ratios into any fd box is a doddle, use factory manual if you donít already know how.
As Charlie said, only sensible to use disc swinging arm with bigger uj and support bearing. Whichever fd box you use, use later big bearing pinion flange not early drum one
