honda vt 600 performance upgrade for better rideability not just noise

honda vt 600 performance upgrade forum question

I am looking at a honda vt 600 performance upgrade for an older Shadow. The owner wants more pull, but the bike has unknown carb history and a loud exhaust already.

I found this related page while comparing notes: honda vt 600 performance upgrade. I wanted a practical thread before guessing.

Would you check compression, valve clearance, carb sync, pilot jets, intake leaks, exhaust leaks, plug color, gearing, clutch slip, brake drag, tire pressure and final drive condition first?

Workshop order

  • Confirm exact model, year and current setup.

It has aftermarket pipes and a flat spot off idle.

That screams carb pilot circuit or intake leak before performance upgrades.

honda vt 600 performance upgrade should be tested on the same road, same rider, and with GPS if speed is involved.
