Did it just stop like you turned the key off, or did it start running poorly first?

How much oil is getting into the airbox?

Do you just have no spark or other issues as well.

You should put the hoses back to how they are meant to be. The sump might have too much oil in it, or the oil may have fuel in it, or the engine may need an overhaul. Those are the usual reasons oil gets into the airbox. Your bike may have a PCV valve somewhere, and that maybe clogged and need cleaning.

I think I'm having the same issues as well

Great information

Oil is getting in the air box from crankcase vent tube, I put the two hoses that go to the air box together then something started to smoke on the front of the engine. There is a filter? In the line I blew that out.

One year later and a DC cdi. Coil Primary 0.1-0.5, secondary 12-20K ohm with cap. Pickup coil 90-140 Ohm. They recommend a peak voltage test of at least 2.5v.

Coil primary 0.5Ohm, secondary 10-16K Ohm. Pickup/trigger coil 90-140 Ohm, cdi charge coil 106-160 Ohm.

I had a sudden loss of spark in my 1988 Suzuki LT300E quadrunner and we tried a new plug but still no spark. Then we checked the boot and there was no issues with it. I then took off the coil as I was going to get a resistance reading with a multimeter however I cannot find anywhere what the readings should be. The coil is a Mitsubishi F6T 411. Any help would be appreciated.

And for the price of one manual you get access to hundreds...

Hi Dave. Yamaha did make one model in the early days that did have a power takeoff shaft at the rear, but it ran at unusual revs and had to have special yamaha implements.. as I understand it. There's one thread about one here and specs on the net

The tiller tines need t rotate at a much faster pace than the wheels so there would have to be considerable modifications`v and expense to try that idea.. My tiller tines rotate at approximately 13 times as fast as the wheels of the tiller. It would be an interesting concept if one of the ATV makers would add a PTO to their machine and offer PTO driven accessories lie a tiller for it . Mate a PTO to a hydraulic pump to drive the accessories.. Who wouldn't like an ATV yo can have fun with on the trails and use the same machine for snow blowing ( or blade pushing as the have now) but also for rotortilling and other garden chore .. A truly 4 season toy /tool.

Is the cdi unit providing an earth for the start circuit when either the brake switch, or the neutral relay, is closed ? Not all cdi do. The one in that diagram does.

For everyone following the thread. Process of elimination. The Start Stop and Neutral relay are SPST NO. So that leaves reverse.

Gw's right about in being leaner, but try turning the mixture screw in and out making sure there is a sweet spot in the middle, and that winding it too far either direction makes it run bad.. That checks the float level's not too high or low, that there are no bad air leaks, and that all the jetting is about right. Checking it's responsive in both direction often reveals a problem. And yeah, stale fuel is something to watch for.. We generally do suggest stale fuel if it sounds like the bikes been parked up for a while.. Good work changing that...

Ha.. good point Gw.. Quads are for fun, not work.. They were using the quad engine though in this case which isn't designed for that type of work, and doesn't have a governor.. It would be horrible to operate !

#66 Easier for who Rancher ?

Ok I’ll try that then let you know

Turn it in to make it leaner.

Yes it’s a mikuni, but the funniest thing happened, I put new gas in it and I couldn’t get it to die when driving. What a dumb solution. But I did find out that when idling it bogs down and dies after a minute or so, I’m thinking it could be getting too much gas so when adjusting the fuel screw do I tighten it or loosen it for restricting fuel?

Too bad you say something is free to download, but you have to make 10 comments before it is available to you when you first start a membership. It's pretty hard to have things to say right off the bat, but when you are trying to download a service manual you don't really want to wait until you have figured out 10 conversations to start. At least it is for me.

Is this a rebuilt Mikuni carb
