Dt360a Rex kit was created by john.lockwood5@bigpond.com

I have a DT360a, original bore, with the standard Rex ignition kit fitted. It won’t rev past 6150 in any gear like it’s been speed limited.
I messaged Rex, they replaced it with a modified kit. Then it wouldn’t rev past 4200 and started to splutter.,won’t go any faster. Carb is good and set up with good mixture readings.
refitted the first Rex kit, back to 6150.
Any ideas? Crank seals are good, compression is 145 psi.
Tacho and Speedometer are NOS and working fine.
