Scooterotica

Easiest thing to try is take out and clean the idle jet and its housing first.
Might get you a bit nearer.

Does it still feel attatched?
The R clip may have broken holding the arm on.
Tank out time.

Lucky for me i have more than 1 T5 so i swapped the stator to another scooter.
The fault changed to that scooter.
Wouldn't mind but when you take it for testing etc..

acko

It was the stator plate which had already been tested.
Gutted but relieved.

My T5 172 has a misfire at high revs.
So far i have changed the carb,cdi,plug,ht cap,ht lead,exhaust,had the stator in to beedspeed for a new pick up and wiring,had the fuel tank and filter out.
Still got a misfire at high revs.
Anyone got any ideas please?

Waste of time putting an expansion pipe on a standard 125.
SIP road has been mentioned will be the best bet.

I fitted the same kit about 3 months ago. Have you left the engine casings standard or are they ported to match the kit? My casings are ported etc but my settings are - Air corrector jet - 160 Mixer tube - BE3 Main jet - 121 Idle jet - 55-160 Engine timing - 18 degrees Spark plug - B7 unless i'm doi...

That idle jet is very weak.
Divide the two numbers together.
e.g. a T5 engine has a 50-100 idle jet giving a number of 2
This is one of the lowest (richest) idle jets.
A P2 carb has a 55-160 which is i think a 2.9.
Not as rich as a T5 but a lot richer than yours which is over 3.
Hope this makes sense.

Start on a 110 main jet and work down.

Fitted my ally Pinasco 177 a few weeks ago.
Getting the scoot taxed and tested next month.
Looking forward to seeing how it compares to my old Polini.
