I'm gonna say this, I have had a blast working on mine. Its been a bunch of nit picky work here and there to get it running smooth and reliably. I have had to re-learn patience again especially with setting timing. They are not the fastest nor are they the best running, and you are right about that fence. Most people will tell you to sell it and go get something else, mainly because they are expecting something that might be coming from an experience with a modern bike and then comparing it to a 360. I have ALWAYS had vintage bikes, hell I think the newest thing I had ever ridden growing up was a 90's KX80 that a friend had. Every thing else was built before I was BORN at that time.
Most (IF NOT ALL) of the issues with the 360 engine is mainly due to the fact that in this country, they were/are considered throw away learners bikes. Most people got them, learned how to ride them and never took care of them before looking at the next big thing or deciding they didn't like them and parked them, either running or blown up. My bike had 22000 MILES on it when I got it and the reason it got parked was that it was run for a bit with GAS IN THE OIL. THRASHED EVERY bearing in the thing. Near as I can tell it had the original head on it when I got it and I polished the journals and put it back into service with a better crank, pistons and barrels. I just recently replaced the head be cause the spark plug hole stripped out.
The suggestions I have taken to heart are basically simple. Follow the maintenance schedule TO THE LETTER, matter of fact change the oil at 1000 instead of 1500 using good quality, oil NOT FOR CARS. Keep the cam tensioner TIGHT and stay out of the redline for any major amount of time as the oil flow at that RPM is not enough to keep up. Other than that ride the dog shit out of it.
Above all remember its a 30+ year old machine, ANY old bike will require something to make it happy, hell that's most of the reason WHY I like them, is the tinkering.
