I have reversed the intake elbow so it faces forward...

The bolts are in the same plane. You can eyeball through one and the other one is right in line.
There is some play between the tops of the bumpers and the frame stop. This allows for a surprising amount of forward and back movement of the engine as bumper arm rocks. I think this is designed to protect the engine from thrust forces rather than provide part of the suspension.
The mount does interfere with any carb or manifold that extends back farther than a standard GY6 carb. It's a PITA and I'm trying to design something that will allow intake mods without trying to work around it. Rich OK, got it. When you say "some" play, what would be considered a "normal" amount to aim for? (Distance from bumper to stop, unloaded so both bumper distances are the same) As for the carb clearance issue, I can see where this will be a problem and I'll keep it in mind on the next build. Thanks! |

I have reversed the intake elbow so it faces forward... Thanks for the reply. I have seen this done (online pic's) on some scoots. When reversing the intake does it change the angle the carb is mounted at? If so, any problems with flooding/starving? I will keep this idea in mind though. |

Yes... you need to machine an aluminum plate to go between the elbow and the engine... I raise it about 3/8" and bevel it to about 10degrees..to make the carb level...

The height depends on the carb clearance.. I always check it first and then machine..
You know measure twice machine once...
the only other unknown is if the throttle cable will reach.. sometimes they do
and sometimes they don't, so you have to replace with a longer one...
Mostly depends on how it is routed...
