How to Change Point, Get Spark and Set Timing with Light - Honda Z50 CT70 SL70 XL70 CL70 ATC70

[@mmetz1877]

Thanks for the timing tips and learned CT70H has an advancer in flywheel!

[@scalecraft4663]

Thanks for the info.Bike lokks in good condition. Better than the one I just picked up a week or so ago. Had a new in 71 , wanted one again.

[@eastcoastish]

Awesome, I've used some much more difficult methods for setting timing, I'm definitely going to pick up a timing light.

[@paulhamilton4756]

I would have liked to hear if opening the gap or closing the gap would advance the timing. I'll have to try it myself, Great video. Thankz.

[@cd43sam]

Nice video. I was hoping as I watched that you would show the advance happen while you had the timing light on the mark and rev the engine. I will now have to go try it on mine as I am too curious. Will also have to research how the old ct70 advances timing as I don't think they have the mechanical unit in the flywheel?

[@opinion4246]

Very helpful thanks 👍

[@eastcoastish]

Great video!

[@chaleeher1992]

Be nice to see on top on the flywheel to see how you really line it up

[@my50bike]

Great tips thanks bud... Where did you get the timing light it's a great tool to have. Thanks for the video!

[@VintageHondaMinis]

I use this light from harbor freight. You will need an external 12v battery to power the light. ---www.harborfreight.com/timing-light-with-advance-40963.html

[@michaelcarroll9487]

Brilliant!

[@dannymotovlogs4254]

Where did you buy points from? I have the similar cl70 motor and could you show a close up of what you were adjusting and how on that screw inside for the timing finesseing ? Was gonna message you on Facebook privately but figured other people could also learn from the comment section. Thanks fir the detail and this is what I was trying to figure out with you the other week. Perfect timing for me for this video😄

CHP in Texas, NEVC(Hondanuts) in NY or TBparts

[@chriscamp8608]

Your Honda has a little different set up versus my 1970 CL 70 because I have a black hub with slots on crank that u didnt have I wonder why they left earlier style like I have ??

[@cainbeeping8480]

Thanks brother

[@salvatorediiorio800]

I have a '73 Honda XR-75. Recently purchased. What engine oil do you recommend. I live in florida....just run the engine once a month. Thanks............Sal

[@huddb6253]

That sys you use is not really correct yea it cranks and runs but you did rev it out to see if the max timing was correct thus verify if the advace mech in the flywheel is working,and points need to be set a certain gap with a feeler gauge about .016

[@bartgoins1782]

With the idle set as high as it was, the mechanical advance was probably coming into play already. I'm sure there is a recommended rpm for idle, IF you are going to use a timing light. Without a feeler gauge and tach, he basically timed it by ear. It may, or may not be set correctly, but he and we will never know. I just picked up a non running 74 XL70, and looking forward to going through all of this with mine. I plan on doing a full restoration on it. If you have a channel, and have some good advice to help me along, please let me know.

[@brianstevenson7520]

How did you know the OEM point was bad?

[@joharb]

Does anybody know what causes the f mark to jump around when viewed with the timing light?

[@connorssmallengines6663]

Hi man, I have a 71 c70 with the different ignition system on it where the points are directly under the points cover and the alternator is a circular one. Do you know where to get parts for that system?

@@VintageHondaMinis thank you so much

[@PaulCTownsend]

Are you readjusting the points gap or turning a plate through that slot what.

[@hrsey71]

readjusting the gap timing. when he turns the flywheel, then closes the gap and re-tightens, it changes the time when the gap opens. then he looks at it with the timing light to see if its correct. if its not, he tries a different point on the flywheel until its correct.

[@johnwhite192]

Was those fly wheels only used on sl70? My ct70h has one is it incorrect?

[@VintageHondaMinis]

They both used this type of flywheel with advancer. 3 speed ct70s/z50s used a different non advancing flywheel. Crank end taper is specific to each setup too.

[@mysterycomment1553]

Sorry but you should be setting point gap by feeler gauge as well not just whatever.

[@VintageHondaMinis]

It is not whatever. I'll trust my timing light over a feeler gauge. Not every point is perfectly built, there are variations that can cause bad spark timing. You can use your feeler gauge, but the timing light will provide the final say.

[@dean3919]

@@VintageHondaMinis exactly.

[@dean3919]

timing light is the true mark ...

[@mysterycomment1553]

@@VintageHondaMinis not true. You set the timing mark to the F. Then use a feeler guage for point gap. If it’s not within tolerance then change the points etc. your just doing random testing. By the old school light method and feeler gauge it takes literally 30 seconds to 1 min max to time these bikes.

[@mysterycomment1553]

@@dean3919 if you set your timing like him then you guys need to go back and learn how to work on these bikes. You do not start and stop a engine a million times with a timing light to set points.

[@karlklein2966]

Too much wind I could barely hear you. Why not do trhis indoors?

[@randygilbert4577]

Its pronounced points. The s dosnt make it plural.

[@plusblood5101]

Poor style No proper wrench for points nut No feeler gauge to set points No clues whether points are wide or Closer Which direction to approach for closer Timing But timming light was gr8

[@paulhamilton4756]

I would have liked to hear if opening the gap or closing the gap would advance the timing. I'll have to try it myself, Great video. Thankz.

[@CraigStaley-v9x]

When you do points and set points 12-16 gap per spec closer to 15-16 will advance timing
