I am just running in a Malossi kit on my T5. Did about 100 miles at 40, no problem, next 100 at around 45-50. no prob. I then went on a lngish run getting it occasionaly up to 55 mph. Never thrashed it , kept it steady. aftre about 45 mins the engine died on mr. No seizure just would not fire up. After 1/2 hour it eventually kicked up, but ran very poorly, almost cutting out and not ticking over correctly. it does start now but when it gets warm it will not tick over or run correctly.
It has a simminini ? exhaust and standard carb.
Hope some one can help, i was running it in correctly as well, sholud have thrashed it from the outset.
Cheers in advance
