Thanks for the upload, great video, i have had trials bikes for over 25 years and they all have their issues. At 3.50 you cracked off the cylinder head bolts ant-clockwise but really you should be following a star pattern diametrically opposing each other to avoid warping the head. Keep up the good work, thanks again.
It’s the same with me ,I fitted a new set of friction plates to my Yamaha dt175,it still has the original Japanese screws fitted,a bit of persuasion with an impact driver fitted with a JIS impact screw head,& two gentle taps & everyone of them came out
Great video Baz. Anything bike or van related for me. you may show a little tip on doing something I've never thought of. Like fitting the engine when the bikes on it's side. Also didn't know they did time serts with different outside diameters,with the thread size you want on the inside.
Absolutely love your trials videos mate and love how you expalin things in a simple but informative way but find the msuic distracting when it's playing over your dialogue. May just be me but thought i would let you know! Keep the trials vids coming!
Pretty good that in a normal garage environment. I'd like to have seen some rag stuffed into the crankcase mouth and a bit flippant about the use of torque wrenches(tongue in cheek probably) Good video production with appreciated voiceover. Of course we want to see the sump guard larger thread fix!
I have a TRS 300 and I think their oil mix recommendation of 1% is not enough oil. I use Blendzall Green Label 60;1. Blendzall runs toward heat, all other types of oil run away from heat. I used it in all my MX bikes and my Speedway bike.
I think you've done ace with that. Plus it's hard filming and working at the same time. Maybe you could use a nutsert but for an 8mm thread you will have to drill it out to 12mm 😊👍👍 I'm just starting trials riding at 55 as I've just lost my license due to a seizure and it will hopefully keep my hand in and make me a better balanced road rider for when I get it back too. The only thing I feel sorry for you though is you're so near to Lancashire but not in it 😂😂😂
The manufacturer recommends these new sealed bearings. Obviously there was an issue with the old bearings not being adequately lubricated by those galleries, possibly because of krankcase pressure actually forcing the lubrication back into the galleries and away from the bearings. This could be the reason why the new sealed bearings actually seal off the galleries deeming them redundant (pure speculation on my part). Your experience with this bearing issue reinforces my theory that there was indeed an issue. Three sets of bearings on a bike that isn't that old and hasn't been ridden excessively can't be considered to be fair wear and tear. If the bike had been abused and not well maintained there would most certainly have been evidence of wear in the bore and on the rings. The fact that piston and rings are original and show minimal signs of wear endorses my theory.
@@SpecialisedMotorcycleTransport Sorry mate I don't but you asking the question prompted me to Goolie the topic and found a lot of threads on the subject. Trials central especially, with comments on your specific bike and an obviously well known problem and questioning these galleries and that manufacturers like Bultaco, in the past, never had such a system. I know that was a long time ago but at that time (yes I'm a dinosaur) Bultaco were king of the game and renowned for their reliability.
That theory does appear sound(wish l'd thought of it 😁but we didn't have the full picture. ) especially looking at the considerable oily residue at the transfer lead in area AND that the big end has also succumbed. The quality of bearing suitability was discussed in last video comments but now appears not to be the issue.
@@bananabrooks3836 If the quality of the bearings had been the issue then they would have just changed the spec of the bearings but they have now completely changed the design of the bearings and the method by which it's lubricated. In some forums it has been speculated that these galleries weren't for lubrication but for added ventilation but I can't follow that logic.
Hi Guy, you left the dust seals on the bearings so motor now can't feed 2T lubrication up and down the gallery ports and into the ball races. Also the crank dropped into the left hand bearing way too easy. The crank will spin in the bearing inner race and stuff the crank. Normally/sometimes you have to pull the crank into the mains, even when you freeze the crank and warm the bearings. Also using a soft hammer on the crank will knock out of true, and possibly why the previous bearing didn't last.
As I explained in the video The bearings are the superceded ones from the TRS dealer that are meant to stay fully sealed mate. This is the word of Steve Saunders himself. Also when we stripped it again to remedy the gearbox issue the bearing was tight in the casing while at room temperature.
I’m a subscriber to your channel but will you please do me a favour please stop the annoying music I want to listen to you and watch what you’re doing rant over good vid as always 👍

GOOD JOB MATE!! GREATS FROM TOLEDO SPAIN!

You should measure the end gap near the top of the cylinder where the rings wear the cylinder.
great job baz sounds sweet enuff to me lad keep up the great work next video please

Thank you buddy..
I'll try to make sure the sound levels are better in future. 😉 Cheers for the heads up.

I have a click in my elbow at 15nm didn't you hear it? 🤣😉

Great job hopefully you'll have lots of fun with it.
Already started that today Brian. 😁
Just heard you mention nsk bearings there made in Newark on Trent
Very interesting 👍👍👍👍
Thank you! Cheers 😁

Check for excessive bearing preload, that was the problem with my 2017.

That does make a whole lot of sense to me aswell Laurence..
Are there any other manufacturers that are using a sealed bearing like this?

🙄Did you not listen?
Is that Billy from stranger things?
When you put yourself and your work is up for criticism and the armchair experts but you and your dad and Connor do well.
Yea I'm aware of the criticism coming but I live and die by the sword. 😂
God my spelling sorry
🤣
I hope you’re not being Chineseum bearings
Always use the best bearings usually from local stockists. NSK NMB or FA6. 😁
I’m a subscriber to your channel but will you please do me a favour please stop the annoying music I want to listen to you and watch what you’re doing rant over good vid as always 👍
Ah thanks Steve but more people stay and watch the whole video when there's music on it.
Wish I could keep everyone happy.
I like the tunes me 😊
Great vids, just sent a request via your website to ship two bikes from Norwich to Newbury 👍
