Highwaystar

Post by eyupwotsthadoin »

Hello. I will admit I was that person that bought the 125 Highwaystar. ( Titter ye not missus). My problem is this.
The engine runs fine in all gears except second. Free revving in first, Change into second and the engine gets to 3500 rpm and it just wants to die.
It did this once and totally cutout when pulling to traffic, made mr nipsy twitch a bit.
I have fitted new plugs , 0nly run it on E5 fuel either shell 99 octane or BP 97 octane and still get the same issue.
Does anyone have any sugestions as to the solution.
Also , does anyone have any ideas as to which OBD system will be able to read the Delphi MT05 ecu rather than pay the silly price as shown on the AJS shop for a diags reader.
Ta very much.
Trog.

If it's fine in all other gears does it have a gearbox sensor to tell the ecu what gear it's in? if so
could be that or the wiring to it, if it has a gear indicator on the clocks could be something to
do with that. If it's always done it from new could a pin on the ecu plug be bent?

Thanks Ralph. No this doesnt have a gear indicator on the speedo. this is a 2019 model. I'll have a look at the pins when I get some time.

What did you use to read the codes in the end? Or can you step through them on the bike, as can on my Guzzi?

Hi I am a VERY new member but VERY oId! I am very pleased to see the modern bikes catered for Done years of Beezers and a Triumph 21. But they all too heavy and too tall for me. Have recently bought an e-2 It does everything I want.So I am really chuffed with it I bought it from a friend who preferred it to the Cadwell which I quite fancied.Look forward to reading your comments on these great machines.

for 320 eye to eye. A simple job which lowered the bike ( an e-2 ) by around 15 mm. When I got back from my trial run I couldn't stand the bike up it was leaning to the right.I had obviously reduced the ground clearance. So now I am altering the kickstand. .Something I didn't think about.
