75 rd 350 high flow oil filter?

[suthington13]

Does anyone have any suggestions on a high flow oil filter for a 75 RD350?

You have to use a high flow oil filter on that bike, if not the camshaft journals will run dry, if they run dry then the powerband might not open, even worse the powerband might stay open when you want to stop, then you will have a powerband on the run.

Maybe a high flow filter, up one size on the powerband (maybe a blue one), and long duration cam would work well together.

Actually, I would go with the LOW flow filter. Reducing the flow is like installing a set of underdrive pulleys on a 5.0 Mustang. Lowering the flow will free up horsepower to the rear wheel up to 10%!!! You can make the low flow filter yourself too, with a stock filter and some burlap. Detailed instructions are online, Bing it.

I would be tempted to pull all the valve train stuff out its too restrictive and make it a two stroke.

You should realize that you are taking so much smack because your RD-350 is a 2-stroke, and has no oil filter. It does, however, have an oil injection system. This is for 2-cycle oil that gets injected, in very small quantities, into the intake manifold, or the carb, and gets mixed with the fuel as the engine sucks the mixture in.
In short, there is no "high flow oil filter" required, or made for this machine.

We all do love to see pictures of any remaining 2-strokes still running and on the road, though. So, if you have any (pics), we would all love to see your ride!

Nuts. I was looking forward to the discussion on when to change the blinker fluid.

bring, brinnnnnnnnng!

I try to ride it every week. Always by myself though. Small tank, stench of premix, and the fact i ride it like an a-hole doesnt help me.

[gregp]

Very Nice! That is what I am talking about!

Sorry, but the guy only has 7 posts, and I like to help new guys out when I can.

Nice! Where did you get that seat? What brand pipes are those?

[VTRumble]

The seat and foam are from e-bay the seat pan is original. The pipes are Spec-2 classics. Lots of fun, looking to have some porting done over the winter.

[Stromper]

I had an rd400 and did everything porting, pipes,big coils, radial head

It seemed like a little animal the powerband hit like a hammer.

Drag raced my brothers stock one and beat him like by a length even though mine was almost undriveable

[boosten lebaron]

Ive come to realize that when you go to far building these things they can slow down just because of the brutal powerband hit. !st gear in mine is nearly useless. I can get on it till about 6k rpms then the front just shoots up and theres really nothing i can do about it. Its fun for sure but if im racing someone i just change gears and wait till the 2nd gear powerband hits then i take off.

Have not checked in for awhile here, rebuilding my front caliper and working on some wiring. Yeah, I know it is oil injected, not my first rodeo. Allow me to be more specific with my initial question. Has any one ever used an in line oil filter on an oil injected two stroke motorcycle for example like on a snowmobile? just curious. Thanks for the entertaining replies . I will be adjusting my master cylinder bearings soon too ha ha ha!!!

[backinthesaddle]

I had a Yamaha dual purpose (AKA enduro bike) back in the 70's . I don't remember either an inline filter between the oil tank and pump, or a filter that was in the tank, kind of like a petcock fuel filter. I guess the thought at the time was oil comes in sealed clean bottles (or so we hope), unlike gas which can get contaminated in the truck or in the gas station tanks. So if snow mobiles are using them today it can't be a bad idea and i would make sure that it is high flow like you mentioned so as to not restrict the flow. Guessing any modern high powered snow mobile's filter would be able to flow more oil than the 350 would need.

[GearHd6]

Most snowmobiles like you said have the inline oil injection filter. Go to any snowmobile dealer and have the parts guy show you some filters. Pick one that looks like it will fit in the line. Most modern day snowmobiles make some serious power and need to flow a lot of thick injector oil through those filters at subzero temperatures.

[gregp]

I would be really careful adding an in-line oil filter to the injection line. Sled oil is very thin, and engineered to flow at sub zero temps. Injector MC oil, not so much. I just would not want to add any obstruction that could possibly decrease (or stop!) the flow rate. I have had plenty of oil injected motorcycles, but I have never encountered a filter of this type. I have seen large foam/sponge-like filters inside of the oil tank, though.

[boosten lebaron]

Dont think you can run an oil filter for it and i dont know why you would. Its a gravity system till you get to the actual pump then it becomes a pressured system and a weak one at that.

Thanks for the suggestions everyone. Here to share knowledge as well.
