Strobe timing.wmv

[gerwoodholland]

Hi lunmad, great videos - thanks once again.

I've tried to strobe my T140E (with a small inspection plug) but get a face full of oil spray when the plug is out. Should this happen? If yes, how do I strobe a T140E? Thanks.

[lunmad]

@gerwoodholland

Hi gerwood

you might get a little oil but should not get a face full, you could drain the oil from the primary case and refill after you have strobed it.

There are three small holes in the crankcase that allow excess oil to drain back into engine it sounds like these may be blocked you should remove the primary case and check they are clear with a piece of wire.

[gerwoodholland]

@lunmad Thanks for the reply. This face full of oil is just that - a real continuous blast. So much that it's impossible to look in the inspection hole. It's accompanied by a hissing sound which I assume to be the high pressure source of the oil. Could this be some sort of leakage from the crank/big end?

[lunmad]

@gerwoodholland

The crank vents into the primary side, gases and oil vapour. The gases should leave the motor by the vent pipe and the oil transferred back into the crankcase through them three small holes and then scavenged back to the oil tank.

There should be only a small amount of oil in the primary side maybe half a cup if that, much more than this will give you clutch problems and oil leaks.

Thank you very much for your information. I have a half dozen bsa and triumphs that I would like to keep on the road for a long time . Your video's will help me do that. Any idea why my exhaust pipes gets red and turns blue? I will try to set the timing by your video and then check my jet size. thanks

[danbonnielux]

Thanks Lunmad for your quick reply and your tip.I didn't think It was worth to run this old bike with the 98 oct. but I will try. I set the timing at the basic 38° before tdc and then I set It down a bit till the engine stop pinking when running up Hill at low load.

hi lunmad have been watching your vid for a year now can i say they are brilliant

i have a 69 bonnie i have set up the carbs as in vid it run ok for a while i stop it

then can't get it to start again. when i check plugs one has stoped working i think its burnt out because when i put in new plug in it runs. it back fires somtimes on kickstart ,my ankle hurts like hell. any ideas .ferritdave

I like the Pazon Ignition as it has little tiny index marks on the trigger plate so if you want to a/r the ignition 1 or 2 degrees, you have a nice visual reference and it is easy to do accurately. Keep it up mate, you are doing a great job educating us all. We are getting close on the warbike, should be finishing the vids up in a few weeks, going to the show next week, wish us luck. Awesome as always, rick

[lunmad]

@62g12cs

Thanks Rick you are doing a caulker of a job on your 3HW

best of luck for the show, will you be riding it there?

I think any bike ridden to a show should be rated x10 above the ever so common trailer queens.

[danbonnielux]

@62g12cs .Thanks Lunmad for this great video.That confirm I was doing the right way when setting up the ignition timing on my 1970 T 120 R(with Boyer Bransden micro digital).My question is:As I run with 95 unleaded gas,should I set down the ignition timing from 38° to 35° or even less.??

[lunmad]

@danbonnielux

Hi danbonnie :-) you should run the highest octane fuel you can get hold of over here it is 97-98 octane.

If not yes you should retard (set down) the timing until the motor stops pinking. You can induce pinking by going slow or up a hill in a high gear then retard timing a little at a time until I can no longer make it ping.

[trumpnut]

Great video but your not close enough to the mic when speaking.

[lunmad]

@trumpnut Cheers trump nut :-)

I do have a tendency to mumble, hopefully what one sees transcends the language barrier.

I have thought of narrating the vids but that will be another project! and I need a mic,

I will try shouting next time ;-D

[flettie22]

I don't have a Bonnie - i have a Trident but I'm still fascinated by Lunmads vids, they're so useful. It's like hanging around his garage :-)

[lunmad]

@flettie22

Hi flettie :-)

I used to have a T150 c/w ray guns it really howled when you got it wound up, but alas it went to the wayside.

I must admit though my Bonnie is a lot less hassle to keep tip top though they are basicly the same.

You are welcome in my shed any time! mmmm maybe some Trident vids ;-)

[spartan3956]

Great just what i wanted better to see than read and it was simple to set up

Hope you do other things to the bike.

[lunmad]

@spartan3956

Hi spartan :-)

I have a few vids up now,

glad this one helped you out :-)

Take a look at my index vid, links to most of them are on there

[srcheney]

Hi Lunmad! When I do my timing the bike vibrates so much I have to hold it fast to stop it dancing across the floor on the centre stand. Your bike is as solid as a rock at 4500 rpm, Whats your secret?

[lunmad]

@srcheney

Hi scrheney :-)

the secret is, I use the side stand, this way both wheels are on the floor so the tyres can absorb most of the vibes.

I use a block under the stand that has the bike almost vertical, then I put a scissor jack under the opposite footrest.

Then as a safety thing, I clamp a set of vice-grips around the foot rest to stop the jack slipping, and screw a pipe-clip over the stand (end) to the block to make that secure.

Most of the work I do is done this way including wheels.

[SPEIRMOR]

I love the videos Ive learned a ton.How does the strobe light work theory wise? why is it connected to the spark plug wire?Im gonna do this on my Norton cant wait to get in to it once I understand whats going on.Thanks Lunmad you the man!

[lunmad]

Hi @SPEIRMOR thanks :-)

there are a few types of strobe, mine connects between the spark plug and cap,

some clip around the HT lead with an induction loop.

As the strobe senses the HT voltage the lamp will light up, and does so every time the spark-plug sparks.

The battery is to power the light the reason for using a separate battery and not the one on the bike Is in case the charging current upsets the "mechanics" of the strobe and makes it flash wrong.

thanks again

[thirteendreams]

nicely documented.

thanks again lunmad:)

[lunmad]

Cheers @thirteendreams :-)

you've done a grand job on your TR7 and summers nearly here!!

[lunmad]

@egpg2000

Hi Eddy "do I shake?" I'll have to have a look :-D

Thank you for the thanks, great comments like yours and others make uploading these vids more of a pleasure for me.

Luke and I sound so similar, the reward for showing someone "how to do something"

is to see them do it! their success, is your success! if you get my drift.

[spokelips]

Again - thanks!! I was trying to time my '70 TR6R using the TDC mark. No wonder I was having problems.

[lunmad]

Hi @spokelips :-)

You are not the first and won't be the last to do just that.

you can get stroboscopes with an adjustable advance/retard on them,

with these you would set 38deg on the gun and line up the TDC marks on the engine.

[TheReverb1]

...cool

but I really dont understand what exactly the light does

and this works for a new magneto too?

thanks

[lunmad]

Hi @TheReverb1 :-)

the strobe light flashes at the same time the sparkplug sparks,

when it is shined onto the spinning flywheel, the flywheel appears to be stationary

making the timing line show up, and adjusted to suit the pointer on the case.

[TheReverb1]

@lunmad

just see

thanks for your time

[srcheney]

grand stuff Lunmad.

[lunmad]

@srcheney thank you :-)

[notwocdivad]

Hi Lunmad Ican see you changing your name to Mr Triumph, (Not "Bonnie" anyway)

I bet people hope you break bits of the bike so they can watch you fix it again.Yorkshire tv should hire you for a Mark Evans type show Cheers.

[lunmad]

@notwocdivad

Hi notwocdivad :-)

Mr Triumph eh! sounds great! I think Mr Turner has that title though.

As problems arise or not! I will do the vids, to tell the truth my Bonnie has never been so pampered.

I wonder if the telly would pay us ;-) that would be great, especially if they give us a bike to do, It would be down to the crank by now :-D

thanks for the thumbs-up.

[estoniaman]

Great videos!

[lunmad]

@estoniaman thank you :-)

[rajabalhi]

Another great and "timely" vid. Thank you for taking the time to do these.

Yer the best!

[lunmad]

@rajabalhi my pleasure :-)

[67giacomo]

Thanks,that cleared a few things up.You are going to need a stage crew soon.

[lunmad]

Hi @67giacomo :-)

I'm glad you're getting sorted,

I already have my stage crew! guys like you,  getting their bikes fired up and running :-) Great stuff !!

[mackdawg100]

Thanks Lunmad! Been waiting for this.

[lunmad]

Hi @mackdawg100 :-)

of all my vids this one took the longest for some reason??
