750 intruder questions

[jcasey]

I have a 750 intruder that belongs to a lady friend of mine. I am doing a little work on it and have a few questions. What oil does it take and the amount with filter? Is there a crossreference to car filters for this bike? How is the best way to get the battery out? Is there any thing that I need to do that should be done on a regular basis.
Thanks

I have the 750 intruder. It takes 10W40 non detergent motor oil. I buy my oil at the local motorsports dealership.
If you put car oil in these, the clutch plates do not like it. It's not much more expensive for the right stuff,
and it only needs 3 quarts with a filter change. There is no car filter that will fit this bike. I did find my last filter at
Wal Mart though, so they may have one - just look through the book. The best way to get the battery out is to raise the rear of the bike,
and drop the battery out from the trap door on the bottom. This battery location is VERY poor for servicing the battery.
As far as regular maintenance - check the tire pressure, and level of oil and fluids. Every 5 tanks of gas, run a little Seafoam in the tank.
Annually - I give her an oil change, brake and clutch fluid change, spark plugs, check the bolts for tight, and keep it clean.
This bike will treat you well for years to come with a little effort. Check out intruderalert.com, there are many great hints there
on how to maintain your bike !

Hate to break it to you but you do need an oil that cleans the inards of the bike. And you do not need moto specific oil either. What you want to avoid is any "Energy Conserving Oil". They have molifiers that make clutches slip. You can use Shell Rotella...Dino or Synthetic and it will work fine. It has been certified for motorcycle engines and wet clutches. 2 Suzukis in the garage and they both work well with Rotella 15-40 Dino. Cheap and readily available oil.

Or to put it another way: You should NOT be putting non-detergent oil in your bike.
That is only for 2-cycle engines and special applications.

Since the original post was made 3 months ago, I doubt he will see the answer anyway.
It's kind of curious that nobody responded then.

I know this is an old post but you guys have forgoten a very...very important issue with the intruder that i found out the hard way..you must clean the sump screen in on the bottom of the motor..you have a wet clutcha and the material that is left from the clutch that is not caught by the filter is on that screen..If you go to long between cleanings that you will not have any lube in the cyclinders..I had a 88 vs750 intruder that i bought last year that i rode for 3mths and changed the oil and didn't know of the sump screen... Needless to say i now ride a 99 maurader... And finding an engines for the 88 750 is damn near impossible cause they like to spin the main bearings.. just thought i'd add this to possible help the next rider that reads this that doesn't know...

There is no service interval for the screen, and Suzuki does not recommend that it ever be cleaned in the service manual. I have personally put 135,000 miles on one Intruder, and 97,000 on another, without ever cleaning that screen, and on the one with 135,000 miles on it the screen was 95% clean when I took the motor apart. So while your advise is well intentioned, it is factually incorrect.
This screen is just a strainer that only blocks large chips and shavings from being ingested into the oil pump; the filter catches particles that are less than 1/100th the size of those caught by the screen. If your screen was blocked so much it stopped the oil from circulating then it is a symptom of a problem, not the cause of the problem. In order for the screen to be that blocked by sludge there was something wrong with the bike when you bought it, or the previous owner never changed the oil (and all the internal sludge broke free when you changed the oil), or the bike was abused by a previous owner beyond belief to shed that much clutch material. The motor died when the internal oil passages clogged, not from the screen, as it would be quite impossible for the screen, which is something like 4 inches by 3 inches, to get clogged up without the bearing oil passages, which are about 1/10th of an inch, getting clogged also. That's why you could not find a motor: when those little oil passages clog (or the bike is run out of oil), the bearing runs dry of oil, gets hot, and spins, eventually failing completely.
So keep the inside of your motor clean with lots of fresh oil of the correct type, and that strainer screen is irrelivant. But a visual inspection before you purchase a used bike, or every 50,000 miles or so, is a good idea: if the screen starts to sludge up, then the rest of the motor is already sludged up and the bearings are suspect.

Your probably right as far as the mistreatment of the bike before i bought it..But that screen was totally blocked when i lost lube to the cyclinder..I cleaned the screen and the lube was restored..but the damage was already done. After I cleaned the screen the bike would run but had blow by in the oil.The front ring was seized and did little damage to the globe..What the decideing factor for not rebuilding the motor was the crank was burnt.. All I was doing was telling jcasey of the experience that i had and something that he should look at while doing the maint..on the unit..

I have to throw in a question at this point.......

is there any particular filter you avoid or prefer, Dr. Bob?

Me, what is readily available is Fram and my concours has an "element" vs an actual self contained what we normally recognize as a filter with a nice little metal package.

[DrBob]

I was never a fan of Fram filters, but have no loyalty to any other particular brand. I bought the Emco 10-55660 more often than not for my Intruders, usually because I could find a 6 or 12 pack cheap. For my Harley's I use the J&P house brand or Harley brand, whichever I catch on sale.
