Oil-cooled engine maintenance
• Valve clearance adjustment (includes gasket replacement)
• Cam chain adjustment (basically automatic, but we’ll verify it)
• Engine damper/mounting bolt replacement
• Generator damper replacement
• Starter motor O-ring replacement
• Carburetor synchronization (forced opening/closing depends on the situation)
Oil-cooled engine maintenance VR2 includes the above items plus
• Clutch cover oil inspection window/cover gasket replacement
• Shift shaft oil seal replacement
for an additional 8,000 yen.
• Oil-cooled exclusive: electroless nickel engine cover bolts—5,830 yen (tax included) with no labor charge when replaced together with any other service
We replace the damper located on the lower front of the engine. Surprisingly, many used bikes haven’t had this replaced.
We replace it with the later-model version. Vibration may be reduced somewhat.
Gravel accumulates here too. We remove it and keep everything clean.
Starter motor O-ring.
This is occasionally a spot where leaks occur. Oil-cooled bikes have two types of starter motors, so we use the Suzuki genuine part that matches your year.
We replace the generator (alternator) damper.
It’s not a very visible part, but we polish it like this before assembly. It feels great.
Generator damper. You can think of it the same as the rear wheel hub damper. When it wears or hardens from overheating or high mileage, you’ll hear some extra noise at idle. If you’re bothered by engine noise, this could be the culprit.
It’s also a good opportunity to thoroughly clean the back side of the removed parts.
#1–4 IN/EX: we adjust valve clearance on both and check for wear on the cam and rocker arms.
It’s good to know how the clearance changes over time.
You can also see the condition inside. If it’s silver like this, there’s been little overheating and the oil has been changed regularly, so your confidence in the bike goes way up.
We synchronize the carburetors. Combined with valve clearance adjustment, you get a synergistic effect. When all four cylinders are balanced, you’ll get stable idle.
We clean everything as much as possible before reassembly.
Introducing oil-cooled maintenance VR2.
We replace the oil inspection window.
Dirty oil and clean oil become instantly obvious.
We replace the shift shaft oil seal. This is occasionally a spot where leaks occur.
Once you have it done, you shouldn’t need to replace it again for a long time.
We install the replacement, apply rust preventative to the shaft, and we’re done.
Normally +8,000 yen = 57,800 yen, and all parts are included.
