172 conversion, engine mount question

Does the 125 mount fit in the 50 frame instead of cutting the 50 1 down?

or does the 50 1 HAVE to be cut down

Thanks, Ryan

 

you can just cut the 50 mount down which will be easier but i have seen a 125 linkage in a 50 so yeh it can be done but you then gotta well a hook onto the frame so the sring can be attached to the arm an frame

 

hmm i will have a think about it

 

dont use 125 mount jus use a nrg mount n grind the sides dwn works all da tym

 

just use a 50 mount there better anyways make sure its nice and tight

 

125 mount wont do as there is nothing to connect spring to on frame from mount.

 

done now anyway thanks

 

so what did you do then as im interested

 

used the 50 one mate.

i think it was just easier this way.

 

bit thick i am so do you just shave the mounts on the 180 engine then as to fit the mount on the scoot?

like i say bit thick

 

no the mount on the frame needs about 5mm or less takin off the left hand side, try not to take it off the R/H side or the engine will sit out of line with the bike/front wheel

 

so is that all you do then thought it would be more hassle than that

 

No its pretty simple really

 

not forgetting new shock or modding the 50 one and new rear brake hose/cable (usually, not always)

its like with cars, anyone can rip a 1.0 litre engine out and manage to wedge a 2.5 turbo in the gap thats left, but that doesnt mean its gonna do anything, getting the engine in place is only half the problem.

 

i aint a chav so wont be doing this anyway was just interested in the procedure tis all and yeas i did think the loom and clocks and stuff would need to be done as ive done quite a few 6v to 12v conversions on me vespa's

 

anyone knwo what you have to go about to get it registered as a 125?

 

engineers report or garage letter to say that when the vehcle left there premises it wer a 125 but ive known just changing the engine number ont v5 and sending in works sometimes but the few i done i had to get letters

 

on my nrg i just put the new engine numbers in and sent it off
but i have herd of people having trouble doing it this way

 

out of interest if you have the splitter on the throttle cable and you have the carb end of the cable, do you still need to replace the whole thing or can you get away with using the original ?
