Have a couple questions on my Dator. I have been working on it off and on for awhile. I replaced tthe throttle cable so the idle would come down from 4000 RPMs. (The cable was Too short for the carbs)
Anyway the first question is the clutch. when it engages it starts to move at about 4500 then for some reason the clutch shifts and bogs the eng down to about 3500. so right now it has a terrible take off. What weights and spring should be used? (Looking for a decent hole shot but this will be a trail rider so nothing real wild)
Next is the eng. I had it running today and ot seemed to run good. (besides the bog from the clutch) I went about a 1/2 mile and turned around. It was in kinda of a muddy snow covered field. The mud slowed me down so it stopped my momentum so I had troble getting it to move again. But when I got back on good snow it would not hardly move. When i relaized there was a problem the eng would only surge around 4500 barely getting it to move. slowly it got worse until i couldn't get it move at all. I shut it off to let it cool down (it was starting to heat up) when i restarted it about 5 min later it was still not wanting to move but i did get it start moving but it seemed to be working hard like on only one cyl. the eng barely got up to 5500 RPM even after getting it back to the yard. I cked spark after I got back to the yard and both cyls had spark and planty of gas and carbs are clean. Is this a sign of a CDI or stator going bad? The previous times I ran it it did not have this problem.
Thoughts appreciated

If the field was muddy I would say that your Jetted to rich for the outside temp. Also unless you put a heat exchanger in the front of the tunnel (80-84 Liquifire type works the best) or your running fast a Dator won't cool properly either.
They weren't built to trail ride at slow speeds in warm temps. You need alot of air moving across the radiator to keep the motor cooled down

Rich: The lessons we learned about using the 78 Liquifire heat exchanger (which was also what we used) was that under curtain conditions & outside temp the grooved exchanger would hold the snow/slush & freeze up the coolent (even with a mixture of 1/2 & 1/2 antifreeze) under slow riding because of low engine RPM's/ slow fluid movement. This is why I suggested the 80-84 exchanger which had a smooth surface that wouldn't hold any snow/slush in place.

So if I am reading this right the thought is the jetting too rich for the temps. It was about 30 and i think my carbs are about 270-280 in the carbs. ( Have to find my sheet I wrote the jets #s on) The heating problem was because I wasn't moving. I'm not too worried about it and I want to keep it original as it is nice and not restored. I remember hearing I may have to move some shims in the primary clutch to get rid of the bog? Or something like that. (I'm learning the clutching thing)

no you need to replace the weights with none notched weights. this will allow the clutch to engage easyer and at a lower rpm. if you put a heat exchanger in it will be hard to see that it is in there and most people will not care because it will allow you to trai ride it easer.

As Wade said if you install the heat exchanger properly & still utilized the Std. Dator radiator other than longer hoses knowone will be able to see that the exchanger is in there. You will only have 2 round holes in the front of the tunnel to the right of the steering column where the water hoses mount to the exchanger.

On the cooler idea do the hoses go before or after the radiator? And an update on this. The eng must be loosing spark intermittently. It starts out good and ran well. I was doing circles in my 1/4 mile alfalfa field. it ran good for about 2 miles and then it starting acting up and not wanting to move. it won't idle after this happens and has no power so I will be cking the spark system. I have a suspision that it may be a cracked spark plug lead shorting out to ground cause I still have spark.
On a side note is there a place where the serial # of the eng is stamped in the block? My ID plate is gone.
thanks

john deere ran the water through the radiator then the exchanger and back to the motor.

The ign problem and the bog are 2 different problems. The normal bog is clutch related but is very drivable yet. When the intermittent spark occurs it barely moves. Being as the snow is dissappearing fast it is probably to clean everything up and summerize it now. And i will have to think about the cooler thing (As i have an 80 LF cooler for a spare)

Another thing you might want to look at is belt deflection or if the secondary is sticking open. If the belt is worn to loose it will try to start out in a higher ratio and that will give you a bog problem. Its hard to test in the mud I know I've done it
Good luck james

in regards to the bog make sure the secondary clutch spring is in #4 hole. primary clutch should have an F (notched) weight I like a heavier spring than the brown factory one.
Thanks,
Ted
