248cc Inline-4 DOHC - 45hp
Petrol
Check this by revving the engine while in neutral; if the RPMs hang or are slow to return to idle, it’s common to consider that the intake manifold rubbers might be perished and leaking air.
While riding, listen closely for a metallic 'ticking' noise at the top of the engine; it is helpful to note that these high-revving inline-four engines may eventually require a valve clearance adjustment.
Check this by inspecting the condition of the radiator and coolant color; in machines of this age, it’s worth noting that the cooling system might need a thorough flush to ensure the aluminum radiator hasn't succumbed to internal corrosion.
During the test ride, observe the gear shifts; if the bike jumps out of second gear under load, it's worth considering that the internal selector forks may be showing signs of significant wear.
Usually time to inspect the condition of the cam chain tensioner and ensure the valve clearances are within spec.
A common point to consider a complete overhaul of the suspension linkage bearings and a look at the condition of the alternator drive.
Often when owners look into a full engine top-end refresh to maintain that signature inline-four smoothness.
Keep a close eye on your oil levels, as these small-displacement high-revving motors appreciate fresh, high-quality synthetic oil.
Regularly clean and lubricate your drive chain, as a well-maintained chain significantly improves the feel of power delivery.
Periodically check the electrical connections under the seat and around the battery, as older looms can sometimes develop minor resistance issues.
Keep your coolant fresh and topped up to ensure the engine stays happy during those longer summer rides across the North or South Island.
Give the carburetor synchronization a check every once in a while to keep the throttle response crisp and the idle steady.
Estimated repair costs if issues arise
If the bike has been sitting, the four-carb bank might need a professional clean and kit installation to restore smooth fueling. This is a delicate job that ensures consistent running.
Since this is a DOHC inline-four, adjusting the clearances is a time-intensive process. Depending on the current engine state, you might eventually need to budget for a professional service to keep the engine internals quiet and efficient.
After many years of service, fork seals may eventually weep and the rear shock might lose its damping performance. Replacing these will bring back that nimble Bandit handling we all love.
