RT2 360 Help My Knee Starting was created by AirborneSilva

Sure you can retard it.  Let's say for the sake of argument (and because I don't know off hand what the timing is supposed to be on a 360), that it's supposed to be set at 2.9 BTDC then set it at 2.5 BTDC thus retarding it a bit.  Mark T mentioned that for the DT400 and I did have mine set close to that at one point because I was getting frustrated trying to time it at the 2.9 and left it at just over 2.5.  The bike ran fine, didn't really notice any loss of power and yes it did kick easier.  I did eventually change it to the 2.9 once I got my head out of my rear and thought it through

I was advised by the shop that does the reboring of my cylinders to not retard the ignition. Makes the engine run hotter. The Harley Davidson Screaming Eagle manual decompression valve helps in addition to the one in the front of the cylinder. The HD valve is fitted into an Alloy Art CRA-1 adapter that fits in the spare spark plug hole. It has to be manually pushed in before each kick. Also standing on a 6" wood block helps.

 


I also like the RT1B and RT3 but as I get older I find the DT1E and DT3 are easier to start and have plenty of power for the way I ride.
The older I get the better I was.
The hours spent riding my Enduros is not deducted from my life span.

Why not use a regular compression release, you'd have to modulate how much you squeeze the lever for it to start but they are also great for slowing down.

Just close the points to 12thou & providing the built in decomp in the front of the cylinder is clear to work & not carboned up in its valve or the hole leading to the port outlet then she should be good.
One model early 360 had a retard system in the flywheel which i had on my RT1 & that along with the original decomp it was a breeze to start.
CDI ignition off a "79 DT250 with the good pulser coil would be good. They retard for starting electronicaly. Look after that knee.

I can understand a shop saying "retarding the timing will make it run hot" if they don't know circumstances or amount we're talking about.

The reality is gasolines are different and require less timing than they did in the 1970's.

Going from 2.9mm BTDC to 2.5mm BTDC retards the timing on a big bore from about 20.9 degrees to 19.4 degrees BTDC... a measly 1.5 degrees. Engine won't overheat.

Some engine builders have reported slightly more power on the dyno with a little less timing (roughly 2 degrees) on 1970's two strokes.

From my experience just that slight reduction makes starting much easier and kickback very rare. I never noticed a loss in power or any tendency to overheat.

Try it or don't. It's your bike (and leg).

Also for me the benefit of the additional decomp valve is that it takes less strength for me to kick over the 360.

Did I mention that the older I get the better I was?

Just my opinion below--or what I'd do.
It's easy to retard from where it is now which I gather is kicking back like a mule. Just reduce the gap, that simple. You could see what open gap you have now & let us know. If it's over 15 then I'm not surprised she kicks back hard, so anything less is only going to help right down the 12 minimum. Otherwise its slot the back plate a little bit so you can move the plate "forward" to retard it more than gap will reasonably allow. Shouldn't be necessary to go to that extreme though.

It's not that difficult to set the points at 12, just use a feeler gauge and when the points are at there widest point loosen the points, put your feeler gauge in there so you can adjust it to that point. That's how I checked to ensure my points weren't opening past 15. worked for me...

It is hard to do with flywheel in place but not impossible...
