Extremely informative, thanks a ton for making this video. I know there are a few but none had mentioned the factory timing marks or were as descriptive.
Good eye! yes, thats an extended reach plug (like the 400's use).. in the background is another rd with an LC motor in it, it uses br9Es plugs. thats what i had laying around as an example. I typically set the timing to 1.8mm btdc and run B8Hs plugs in the aircooled rd 350's, and the 9 series in the kawi triples.
Thanks for the video. I see that you have checked the timing and proven that it is indeed at 1.80mm before TDC, but how would you adjust it if it wasn't where it needed to be?
Hi what spark plugs do you use? Mine are keep getting whet and are broken verry fast:( Do you also now somebody who has spare parts for an Yamaha r5 350? Greetings, Nathan
hello from the uk i have a 2stroke ryobi strimmer no spark fitted a new ignition coil has a faint spark so ime thinking the timing is out would this principal work with my engine ie timing gauge but were to start i dont know being a layman money carn't buy experience thanks den.
i assume your dial gauge is metric. mine is in inces. for 2mm could you please tell me how many turns it should be for a standard gaige and where the needle should stop. i'm timing a new vape electronic ignition system at 2mm btdc. thank you
2mm = 78.7 THOUSANDTHS of an Inch Aka .0787” I’m assuming one full Revolution of ur gauge is .01” and ur tiny inner gauge holds that number. So I need to zero out ur gauge first and then spin engine clockwise (backwards) until ur gauge reads 9 on the tiny inner gauge .09” and 0 on the outer gauge. Then rotate engine counterclockwise (forwards) until ur inner gauge is at 7 (.07”) and (+) ur outer gauge is at 87 (.0087) = .0787” before top dead center. This is where u want it to spark.
i usually do set with a light. however, when i made this, people were asking about how to do it with a dial gauge. also, on some bikes, you need to use a gauge to set the marks to check with a light, or if you change to an aftermaket cdi setup.
@@rooskie yes, I have 3 RD350s and use timing light only now. I used to use the dial gage thing, and it was a lot of work and pain. I checked with timing light and found it to be correct and also had the advantage of seeing how steady the spark was to diagnose other problems.
@@rooskie Yes, once you have established and marked where you want your timings to be using the dial gage method, you can use the timing light from then on and get perfectly timed engine. If you think about it, there is no gear lash, you are timing right off the crank and the timing light is very accurate. I have had a number of older automobiles of the late 60s and early 70s. If they had do it yourself instructions in the owners manual, they advised either static timing or timing by dial gage for motorcycles. This was because accurate timing lights were very expensive back then, and the cheaper ones were not accurate at all. That is why no owners manual of that period would suggest a timing light. Today it is easy to buy a very accurate timing light. but those old schoolers still think they are doing it better by a dial gage.
You don't have to do all this. In its day, timing lights that were anywhere near accurate were extremely expensive. Almost all vehicles with service manuals when they gave how to do service in their owners manuals only recommended static timing and not mention or allowance of timing lights. Zoom ahead to day and the timing lights are accurate, respond in the time parameters necessary and static is obsolete. If you don't think so, do this static timing and when you get all done, check it with your autozone timing light. EXACTLY the same!!!!! Timing is a breeze with a timing light, not doing all this!
I agree 100%. however, there were always questions on how to do it on the forums. (which is why i made this video a decade ago) And, it is necessary if you fit an aftermarket cdi or are working with an r5 or the like with moveable timing index pointer.

awesome video !
That dial looks familiar! Thank you Mark for finding the problem w/ the dial guage.
Top video mate, explains exactly where I was going wrong, thanks
It helped me with my Daytona special thanks

I'm new to this so, when at 0 on TDC and timing needs to be at 2.7mm BTDC it's 2 complete rotations from 0 then stop on 70?
Thanks Mark! (Adam)
Look at all those rd's in the background
If timing is off then what? Move point plates till it sparks at the desired measurement i.e 1.8mm BTDC? both pistons on just one ?

Very good video rooskie I have a 1972 R5 350
thank you. i need to do an updated one with my go pro and cdi installs. (powerdynamo and hpi).
@@rooskie Hey Rooskie, thanks for sharing. Have you posted a powerdynamo (vape) video yet?

Check the voltage to the coil with a multimeter. Should be between 12V to 13V. Its a late reply, but might help someone.

Why not just a timing light?

@@greatgambino well, like said, with cdis with no keyed rotor (i have 2) and r5's with a moveable index, you need a dial gauge to set the pointer. .02
