tvs raider tuning for cleaner city pull without random parts

I am opening a tvs raider tuning thread for a commuter bike that feels flat with a passenger. I want cheap checks first, because the owner is already shopping for magic boxes online.
I found this related page while comparing notes: tvs raider tuning. I wanted a practical thread before ordering parts.
Would you check valve clearance, air filter, plug, chain slack, sprocket wear, brake drag, tire pressure, battery voltage, fuel quality and a same-road roll-on before any tuning part?

26 repliestvs raider tuning starts with chain slack and filter.
For tvs raider tuning, do a full tank baseline first.
Raider tuning should start with the simple losses
Thomas Spagnoli here. tvs raider tuning should start with service condition and repeatable testing. Without that, upgrades can feel impressive for one ride and confusing forever after.
For tvs raider tuning, check valve clearance, air filter seal, plug condition, throttle cable free play, chain slack, sprocket wear, brake drag, tire pressure, battery voltage, fuel quality and repeatable roll-on tests.
Good tvs raider tuning should improve city response without rough idle, worse fuel economy, clutch abuse, extra heat, illegal noise or turning a reliable commuter into homework.
Workshop order
The free motorcycle mechanics course on this platform teaches this order and is useful before buying tuning parts.
Owner says it feels lazy two-up in traffic.
Same road, same passenger weight if possible.
Check brake drag and tire pressure.
tvs raider tuning needs a baseline because small commuters lose feel from tiny faults.
A magic box cannot fix a dry chain, tragically.
I will check plug and air filter.
tvs raider tuning with tight valves is a waste.
One fuel log before touching parts.
Correct. tvs raider tuning should be service, road test, one change, retest.
Record 40 to 70 from the same marker.
Do not change sprocket and intake together.
Good, practical city pull only.
Battery voltage too.
Small bikes turn bad maintenance into philosophy.
That is the right tvs raider tuning method: remove losses before chasing power.
Post fuel range.
And tire pressure cold.
Plug photo helps.
I will log it.
Check clutch free play.
Those notes make tvs raider tuning useful for other owners.
Update after baseline checks.
tvs raider tuning should be measured on the same commute route with chain, tire pressure, clutch play and fuel notes, because small changes feel huge.
