New Massimo Buck 450

[Bobb]

Just bought gently used (16 miles) Massimo Buck 450 and I'm having the idle won't run when you step on the gas issue???   WTF??  Is it in fact the exhaust sensor??

Was it running good when you test drove it?

[Bobb]

Yes, it test drive fine. Had 12 miles on it then, 16 now??

Make sure you buckle the seat belt,  even if you don’t strap in, buckle the seat belt.  Some of these have “safety”, that limits the engine unless the seat belts are buckled.
