10W-40 15W-40 etc As I am unable to tell how long the existing oil has been in the bike should a flushing oil be used befor changing the oil? Any help/suggestions/advice would be appreciated. Regards, ,according to 900 Sei WORKSHOP MANUAL Additions and changes to the workshop manual for 500 Quattro-750 Sei whose print date appears to be 2-80, AGIP SINT 2000 SAE 10 W 50 oil is to be used for the engine. I drained the oil and changed the filter on my 1979 750 with 380 miles on it last May. I bought the bike new but haven't used it since 1993. The oil and filter were again changed after 12 miles. regards,,,

Just installed new seals need fork oil capacity and best type to use bike has 4500 miles


Damper oil is traditionally a fairly light grade of straight mineral oil; SAE 20 or 30 is typical but people have their preferences and sometimes with good reason and I have heard of all manner of oils being used from auto transmission fluid to engine oil.

Your bike specs should tell you what oil and how much is recommended for your bike or any motorcycle parts department or repair shop.

Where do you put the transmission fluid in on a 1996 cbr 900rr


hi,the transmission oil and engine oil are the same thing,one oil does both,hence why bikes use a multi grade oil,normally..most hondas you will find engine oil/trans oil filler on the top of the r/h engine side cover...hope this helps...cheers

Dear Sir. The engine oil flows through the starter clutch which acts as a centrfugal oil filter. Sludge builds up and causes the starter clutch to slip.

It is possible to replace the Benelli 900 starter clutch without having to remove the engine.
It requires removing the clutch, then the side casing and gears. The sump needs to be removed...middle exhauster header pipes first. The lh engine cover and oil pump also needs to be removed. The primary drive shaft can then be removed from the RHS of the engine. the primary drive chain and satrer clutch assembly will now drop enough to enable the removal of the sprocket from the starter clutch (it is a bit tight and then the rest of the starter clutch will come out of the chain. Be aware that the oil pump drive connector is on the end of the primary drive shaft and care needs to be exercised. This is possible if due caution and care is taken. Assembly id basically reverse of above. Happy fixing.

Dear Pravin,

Always check for the oil level before you start for the first time during the day. If you can just shake the bike you'll know how thick or light the oil is. The more lighter, you'll have to change faster. Also check for color. Oil can be maroon/red/dark green/etc. depending on brand. If its really black, change it fast. Dont do top ups. Better drain the entire oil and fill fresh oil.

The oil also acts as a lubricant to the gearbox. If you feel gear shifting is becoming too slippery or too tough, check for the viscousity, as said earlier. Slipping gear shift can also be due to a loose chain. So check for that too.

By the time you finish 1500 kms or 2000kms, its better to change the oil.

It is better to use Castrol Power1 for Pulsar. It prevents overheating and also keeps the engine and gearbox smooth. It also maintains viscousity at high temperatures for better lubrication.

My experience:

I used to put servo and every 900-1000 kms i had to change oil. Now with Castrol, I change only between 1500-2000kms. I'm getting mileage between 50 and 55kms for a litre of unleaded petrol.

Hope this helps in solving your problem.

Have a nice time riding pulsar.

Always wear helmet and drive safely.

Weak spark


new battery in itturning over nicely after chasing down a few bad grounds but have very weak spark.I had cam2 in it even and couldnt get it to fire.I suspect coils or possiblly grounds still .Question iswhere can I get these electrical parts for the bike?(dont all answer at once now...)I think I need pickups for the bike as well but am going from memory on that one.ThanksHave you tried changing the ground from the coils to go straight to the frame and NOT through the sidestand cutout? I don't trust that little fella. I've rewired mine so it kills the satrter motor instead - can't start the bike with the sidestand down - and as I never get off the bike leave the engine running with the sidestand it's not a problem. It does mean though that if the switch gives problems (i.e. in the wet) it does not kill the engine.,,,

Fork oil


but does anyone have experience of adding a firmer fork oil to the 900 Sei? Road tests I've read suggest that it may improve handling and hard braking particularly in reducing rear wheel chatter when throwing out all the anchorsThe 900 Sei uses damper insert cartridges in the top of the fork leg. The oil is ONLY for lubrication of the fork and tube. All the damping work is done by the cartridge therefore changing the oil will have no effect. The only thing you can do is change / upgrade the damper units. When I rebuilt my bike I used some air assisted ones by FAC. I'll have to look up the details for you, but mine are up for replacement now too so this is quite a current topic for me too,,,
