Your videos are the most helpful, instructional videos that exist on TH-cam! I have a '69 T120R with a '71 engine. Your videos have kept that girl on the road for many miles. Shes my daily rider and usually cruises about 100 miles a week. The weekend comes and I'm usually taking her up north camping. I'm a huge Triumph fan and love to see people use their Trumps and keep them on the road! Im a huge fan of all your videos! Keep the coming! Thank you for all the help!
you have all my respect sir for dealing with such cumbersome adjustments that only Britt bikes are used to I deal with japanese and spanish bikes and let me tell you my hat goes off for your patience and perseverance taming those temperamental critters
joined a british motorcycle mechanics group in FB and every issue I see (lots) makes me think they ( britt bikes) are very temperamental it may be due they are old machines who knows what previous owners did or did not anyways is a very nice group and am learning a lot eventhough I do not own a british bike but fond of mechanic thinking & tricks..he! cheers ! love your work
Hi Timothy thanks :-) try boiling the plates in floor cleaner you may need to tighten pressure spring a touch or fit stronger ones. The clutch pushrod must have play if too tight will cause slippage.
Extremely helpful, my friend has a 67 tiger and the clutch is slipping so we are going to put some new clutch plates in it and seeing your video will make the set up easy.
Hi Joshua :-) For a grabby clutch I would be having a look at the condition of basket the slots should be straight and not saw toothed, the tangs on the plates should also be considered. A wobbly pressure plate symptom would be more of a juddery take off.
Thank you for the speedy response I did take a look at slots and they were mared up so I took a little time with a small file and they cleaned up nice, but it didnt fix my problem. So sir I have a few questions if you dont mind. Could a streached clutch cable cause this condition? and What about hard rubbers in the cush drive? It seems my lever is almost all the way out when it starts to grab than I give it a little gas and ease of and bam! just grabs hard. Im lost on what to do now.
Lunmad, So replaced the clutch in my 79 triumph 750.....and managed to wore the push rod, the adj screw, and the clutch release lever down. Did i over tighten the clutch nuts? how tight should they go.... Grease on push rod when re install????
I'm loving these videos, mainly as a gut check. I did a valve job per another video of yours and now I have decent compression I find my clutch slips more so I have a hard time starting the bugger.
@pixelphotography Hi Clint :-) thank you! I'm so glad my vids are helping, more to come as I do the work :-) how is yours coming on? I've been busy riding mine, and making the most of the no rain ;-D thanks again John
great video, I was hoping you could describe the symptoms of excessive basket wobble? Or what would cause a extremely grabby clutch? It seems that when I let off the clutch, its as if I were dumping the clutch lever rather than a smooth transition. Your feed back would be great. Thank you
Glad to be of help Nick :-) like you I love to use my Bonnie and see others being used as they where intended to be used, I find it saddening seeing them turned into trailer queens!
@gazza70cr Hi Lunmad, Yes ,I will try the adjustment first and then check the thickness of the plates. Can you just tighten the springs a little? What type of oil do you recomend?
@lveihl Hi lvehl :-) yes it is a clutch hub puller, and is one of the "must have!" tools, the hub is almost impossible to remove without one. cheers I'm glad my vids are a help :-) Happy new year 2011
Yes thats the one djfung, There are two types of detent, a leaf spring inside the box, or a plunger accessible from the outside. Yours being a '72 should have the leaf spring.
Hi MrBritrider, I would screw a bolt into the hole, best tap it. Then heat the shaft and knock it out, probably using vice grips to hold the bolt head.
Hi cassioerta :-) A clunk as it goes into first gear from a stand still is pretty normal for the old trumpies crash box. Prolonged grinding when trying to find first gear would suggest to me a dragging clutch.
Hey whats up man, I have 1969 t120. I have a clutch, possible actuator issue. I removed all te clutch plates and checked out the everything in the gearbox cover and replaced the actuator and when I put it back together with the clutch plates still off, when I pull the clutch in its stiff like 60 pounds of pressure , any idea on what it might be?
Hi Lunmad. I'm from Italy and I've really appreciate for this video. I own a 1971 OIF Bonnie and I'm so proud of her...I have a problem with my clutch, I hope you can help me. I've changed everything changable (discs, plain discs, drum, rollers (all the set), rubbers etc) but when I insert the first gear a big rattle is heard from gearbox. After I run I have no problem. I ask for have a suggest to how to fix the problem. Thank you and ride on...
lunmad hi, my triumph t120 r 1971 I put new clutch and when I push the lever cluch you hear a STOC, the last album comes out to hear the noise, what can 'be? thanks
Thats a good point about the studs gordonemoore. I'll add a annotation :-) I must admit I use a couple lever positions when truing the PP. Ooo! them springs get very hot in summer :-D
Primary chain was so well worn , it slapped the (brand new )-stator wire insulation wire to bare wire. I'm really in need of the best place to be getting parts for my T120r , I have a grocery list that keeps growing XD
@mfppro Hi mfppro :-) the 3 spring pressure nuts (screws) want to be nearly down to the cups in pressure plate, if over tightened the springs get coil bound and this will wear the rod.. The adjuster needs to be about 1/4 turn off the pushrod (clearance) if there is no clearance this will wear stuff as you saying. the pushrod itself needs to be the correct hard steel and the ends must be tempered if the wrong steel is used the ends of rod will mushroom. I always use grease on the rod.
Lunmad, haven't seen anything new hoping all is well and looking forward to your new repairs , Wishing the best, Mike Jurasek, p.s are you located in stoke on trent?
@gazza70cr Hi gazza :-) a slipping clutch can be a couple of things, the clutch pushrod adjustment first or contaminated plates I boil my clutch plates every now and again to remove oil.
Hi sam :-) A clunk getting into first gear is pretty normal, but grinding could be tickover too high, poorly adjusted clutch or maybe a bent selector fork.
+Lauren and Rosie Hi Adam :-) with new clutch plates the material will compress with use, so a few regular checks would be good. Checking the pushrod length is easy to do with aid of inspection plug. Slacken cable fully off, then mostly art work adjust the rod, as long as it has a gap (1/4 turn) it will be fine. While you do that you can also check primary chain a bent bit of wire comes in handy.
Nicely done! Two things, NOT criticisms: You showed this, but it's very important that the spring studs (v. 2.0, heh) wiggle like that. If they don't, the stud is trapped behind the clutch center and you will get to do the job over. Whilst truing the pressure plate, don't disengage the clutch all the way, rather just barely enough that it will slip. I'm quite sure your clutch springs are subjected to enormous heat on occasion! (wink)
Ya lol, seems i can get what is required, but from so many different places, shipping would consume more than half the total XD So I sit waiting and searching for ONE place to order - AND , it is warm summer.
you could try British Cycle Supply out of Wolfville Nova Scotia Canada, they also have a warehouse in New Jersey..phone number is 1 800 565 5060..good luck
how do you know if the clutch plate nuts are too tight? mine seems to have lots of run out even when I tighten the bolt on the side with the most run out.
Hi Motard :-) if you screw the nuts in too far below bucket, they are very hard to remove. Removing the run out is more of a work of art. Make sure all the springs are the same length before you start then tighten them to just expose thread at bottom of slot. Next start to do the run out only 1 or 2 turns on the correct nut can accomplish the task. I had trouble with my clutch slipping so ended up packing the springs. Check out my latest engine rebuild.
@scaringoldladies Hi scaring :-) I have used the ball bearing trick a few times! it works a treat! don't forget to heat treat the ends though. I have since gone back to the four spring clutch, as I was getting clutch slip at around 5500rpm. Fitting four, 3spring springs and cups (if that made sense) has made the action a bit heavy but it does not slip now :-D
Hi Lunmad I have a 6T triumph pre unit the clutch is jamming? I pulled out clutch plates and put in 1st gear and pushed down on kick start, the bike surged forward?? do you have any ideas whats going on? and what to check? Appreciate any in put you have Cheers
Hi Chris :-) that is normal as the kicker works through the gearbox, with the plates out and the bike in neutral the clutch centre should turn freely. if this is not the case the thrust washer behind the basket may of slipped and been jammed during assembly. The grooves on the basket and centre should be almost flat and not saw toothed, a little wear is ok but if too deep the plate tangs can stick in them. I hope this helps.
Hi Lunmad Ok so just to clarify bike off if you put it in first gear pull clutch lever in and push down on kick start the back wheel will turn is that correct?
@gazza70cr Hi gazza the springs don't want to be much tighter than level with the cup they are in. If you screw them in too much they can get coil bound so the clutch cannot disengage. I use Duckhams 20/50w when I can get it but more likely Morris or Silkolene any good 25/50 is ok for me. Some people separate the primary and use ATF in the chain case.
i just replaced the clutch in my 69 triumph with it in netrul i kick it over but i think the pressure plate is slipping it wont engage the motor over can you help
Hi Tylor :-) If you oiled the friction plates that will be the problem. If not you should check the push rod adjustment making sure the cable is slack.
Now then blackturbans, I don't run gaskets on a few of my cases, a dod of silicon and bob's yer uncle :-) All casings if left long enough will start to leak or at least weep.
Love tha bit were you forgot the stud's I was laughing me cock off, coz i could see it, done it my self , love the tools mate great ideas with the magnets I have had 3 Bonnies just bought a 73 Norton 850 and first thing I'll do is fit a belt , I'll do the Vid's as well just like you there great for new owners who dont know the tricks and the home made tools , Rock on Bro !
Hi carlsfenderbender, them studs eh! lol! and all on vid :-D I can't wait to see your Norton vids (use plenty of macro) and quadruple your time to do the job. Tiz a shame you sold your low-rider, she sounded and looked the biz. Love you channel btw you got some great tracks :-)
Hi Joshua :-) It could be a stiff cable but not a stretched one, and worn cush rubbers would show up as a more clunky gear change. Have you measured the length of your clutch pushrod? It may of worn short.
Hi Jo Jo :-) sorry about that you need approx 1/3 pint oil poured in through the top inspection plug. This is only an initial fill as on this model Bonnie the primary oil is self levelling.
Sorry about the sound I had a music back track and got a strike, so I removed it. I did not say much anyway which is why I had music in the background.
Hi Rick :-) Argh! you are not the first and won't be the last to have that problem, sorry I can't help with a supplier I must get a list together one day.

+Fernando Biondi
Hi Fernando :-) thank you
they can be more of an art but once set up are mostly trouble free.
joined a british motorcycle mechanics group in FB and every issue I see (lots) makes me think they ( britt bikes) are very temperamental it may be due they are old machines who knows what previous owners did or did not anyways is a very nice group and am learning a lot eventhough I do not own a british bike but fond of mechanic thinking & tricks..he! cheers ! love your work
Another great video! Thanks for the series. They've been quite informative.
Hi Timothy thanks :-) try boiling the plates in floor cleaner you may need to tighten pressure spring a touch or fit stronger ones. The clutch pushrod must have play if too tight will cause slippage.
very nicely done. my 72 bonnie needs a full tune up. im glad you made all these videos. keep it up!
Yet another useful and demystifying video! Thanks Lunmad.
Hi Dave :-) thank you.
Extremely helpful, my friend has a 67 tiger and the clutch is slipping so we are going to put some new clutch plates in it and seeing your video will make the set up easy.
Hi Joshua :-)
For a grabby clutch I would be having a look at the condition of basket the slots should be straight and not saw toothed, the tangs on the plates should also be considered.
A wobbly pressure plate symptom would be more of a juddery take off.
i just got my first brit bike 66 bonnie these vids are a big help thanks lunmad
Hi dustinkoi we never stop learning,
Triumph gets in yer blood and for me the older ones have the best magic :-)
Hi MrFuckbone a nice '66 luvly a lot of the stuff is similar :-) just glad to help

Lunmad,
So replaced the clutch in my 79 triumph 750.....and managed to wore the push rod, the adj screw, and the clutch release lever down. Did i over tighten the clutch nuts? how tight should they go....
Grease on push rod when re install????
I'm loving these videos, mainly as a gut check. I did a valve job per another video of yours and now I have decent compression I find my clutch slips more so I have a hard time starting the bugger.
@lveihl
Hi iveihl yes it was the Triumph clutch hub extractor pt#1861
the hub can be extremely tight so this tool is a must.
@pixelphotography
Hi Clint :-) thank you!
I'm so glad my vids are helping, more to come as I do the work :-)
how is yours coming on? I've been busy riding mine,
and making the most of the no rain ;-D
thanks again
John
great video, I was hoping you could describe the symptoms of excessive basket wobble? Or what would cause a extremely grabby clutch? It seems that when I let off the clutch, its as if I were dumping the clutch lever rather than a smooth transition. Your feed back would be great. Thank you
Love your show ,need some knowledge on why I have to put the M C in 2 gear and rock it to free up the clutch plates, how can I solve this problem. ?
Glad to be of help Nick :-)
like you I love to use my Bonnie and see others being used as they where intended to be used, I find it saddening seeing them turned into trailer queens!
@gazza70cr Hi Lunmad, Yes ,I will try the adjustment first and then check the thickness of the plates. Can you just tighten the springs a little? What type of oil do you recomend?
should u lean on the kickstart to chain tension right,like on a t150??
you mean the spring that deals with the cam plate?
Good man. Thanks for the most useful tips.
@lveihl
Hi lvehl :-)
yes it is a clutch hub puller, and is one of the "must have!" tools, the hub is almost impossible
to remove without one.
cheers I'm glad my vids are a help :-)

Yes thats the one djfung,
There are two types of detent, a leaf spring inside the box, or a plunger accessible from the outside. Yours being a '72 should have the leaf spring.

That sounds like the leaf spring in the gear box is weak.
It will entail a partial gearbox strip down, but its quite easy to do :-)
Thanks djfung :-)
As things need doing, I'll get out me camera!
so more to come, glad you find them handy.
thanks lunmad, one other thing .... that oil tips to put on this motorcycle?
@lunmad (whoever is now maintaining channel) do you know why there's no sound on this now?
any idea why my 72 bonnie like to pop out of gear?
lunmad hi, my triumph t120 r 1971 I put new clutch and when I push the lever cluch you hear a STOC, the last album comes out to hear the noise, what can 'be? thanks
Thats a good point about the studs gordonemoore.
I'll add a annotation :-)
I must admit I use a couple lever positions when truing the PP.
Ooo! them springs get very hot in summer :-D
Primary chain was so well worn , it slapped the (brand new )-stator wire insulation wire to bare wire. I'm really in need of the best place to be getting parts for my T120r , I have a grocery list that keeps growing XD
Oops, hit send before I was able to ask my question. How do you remove a pushrod shaft bush? I need to replace the worn one on my T140V. Cheers!
@mfppro
Hi mfppro :-)
the 3 spring pressure nuts (screws) want to be nearly down to the cups in pressure plate, if over tightened the springs get coil bound and this will wear the rod..
The adjuster needs to be about 1/4 turn off the pushrod (clearance)

I always use grease on the rod.
This vid was so helpful, thank you.
Hi giuly :-)
It sounds like the clutch pushrod and cable need re-adjusting.
Sometimes un-adjusting the cable a little, gets rid of the click sound.
Hi MrLipyeart :-)
you could and it would make turning the tensioner a little easier, but is not necessary.
Lunmad, haven't seen anything new hoping all is well and looking forward to your new repairs , Wishing the best, Mike Jurasek, p.s are you located in stoke on trent?
Can't thank you enough!! Extremely helpful... THANKS!!!

Hi giuly :-)
it is up to you what oil you use, I use engine oil in everything! including the gearbox and forks.

What year is this motorcycle from?
Hi Stephen it's a 1972 Bonneville registered in '73
Thank you A169KL
Now then blackturbans,

Eeee you make me blush
I'm just glad to help :-)
lunmad, i haven't heard any new videos, just concerned everything is ok.
Its not looking good.
you didn't show how much oil you put and where you put it in from,,,,
Hi Jo Jo :-) sorry about that you need approx 1/3 pint oil poured in through the top inspection plug.
This is only an initial fill as on this model Bonnie the primary oil is self levelling.
Great Job. But I couldn't hear any audio.
Sorry about the sound I had a music back track and got a strike, so I removed it.
