Hello.
I have a 2012 PX125E with a mildly tuned engine. I had a SIP Road 2 exhaust on it for a while. throwing it down my Favorite hill, I got an indicated 69 MPH.
I wanted to see that magic 70 MPH. I fitted a PM Tuning, PM evolution 24 expansion chamber and had 74 MPH on the clock. It's not often I want to kiss a Welder. X X

That's great to hear. PM makes good stuff. Would you mind posting some pics so we can see how it looks/fits? Thanks.

I'll try tomorrow. I have trouble getting pics on here. It's a company computer. I have an I pad at home but can't work that out either.

On a 125 getting 74mph on a Vespa speedo, even down a big hill, is good going.
If its revving that high you might need to re-check the jetting. Whats in there now?

Hello Jack.
I have a 140/ BE5 / 99 at the moment. I checked the speedo this morning. it indicated 74 MPH at 8100 RPM.
I rode with a GPS app on my phone Speedo read 41 and GPS 39. I'm going to JB Tuning in Essex for a DYNO session on Friday. I won't dare rev that high very often.

Jetting a bit weak to be doing over 8000 rpm on. Hopefully the dyno guys adjust the carb too?
Be careful north of the river

Thanks Jack.
Sod's Law. I loaned my 100 and 102 Main jet to my mate Yesterday. the next size I have is a 105

I heard they still eat Missionaries over the River.
