- Putting new piston and rings in a 2007 Dt125x and powervalve and oil pump set. The bike wouldn't start by starter only if bump started then would start all day once the piston had swelled up off the heat

Sounds mint! Especially with that dep exhaust ;-)
Yeah a kno m8 they sound good it should be quick aswell with the 57mm piston in
@@2strokemxclassics yeah be interesting to see the difference it makes, my 99 DT has done just over 6000 miles and hitting 95 PSI on a compression test so good to go for a little longer I hope before a change, when i do will use this video to follow for sure! :-) most of the DT videos online are foreign so hard to understand and translate is crap lol
Yeah a know m8 thanks a watched loads of vids and not enough info av done me best to explain everything on vids, the dtx av just done had 95 psi the limits a 100 am certain and need done at 100 psi m8
Excellent video!👍
Thankyou ❤️
Awesome vid mate Thanks for posting
No probs m8👍
@@2strokemxclassics I also have another prob that you could possibly help me out with. I ordered new wheel rims and i was going to get the hubs powder coated, as the spokes in the rear wheel were rusted solid i cut them with an angle grinder :(. Can i hell fined the sizes for them anywhere. Is theere any chance you could send me the measurements. I have the front spokes but not the rear.
Hi m8 I don't have no spokes out but I was going to remove a spoke at a time on a back wheel to get in at the hub,if I do i will measure it for you sure there's top and bottom ones so I'll make sure if there difo m8
@@2strokemxclassics Cheers mate, I think they are all the same length, the front ones are
Do you have available clutch lining for Yamaha DTR 125r
Hi, I have one more question, is wire in larger part of 2003 dtr 125 standard pipe restriction or not
It's a sound damper,it gets caked in carbon, if your keepin the standard pipe on take it out
Is the side to side movement ok as mine has a bit of side to side but no up and down
Hi yeah side to sides OK as long as no up and down
Thanks
Hi mate great video how do you spin the servo side round to get the second cable in
Hi m8 is it to get the left or right cable in and we're abouts the top on the motor. I'm guessing the right hole on the powervalve disc? Thanks for watching btw💯👍
@2stroke mx classics hi mate its the right cable at the top not the motor the part underneath the fuel tank I see you put the left cable on but then it rotated and you have the right cable on if you understand hard to explan thanks for the reply 👍
@2stroke mx classics it's 20 minutes 17 seconds in mate it's like you spun the motor round to fit the second cable how do you spin it round thanks mate 👍
Hi m8 once the left cables in you can rig the motor plug up, then turn your key till the disc spins clockwise. then wen the disc has moved over turn your key off and you'll be able to get the right cable in the disc m8 hope this helps👍
@2stroke mx classics hi mate that's great putting my eninge back in on Tuesday its just getting rebuilt now also do you have any recommendations for engine oil/gearbox wet clutch oil thanks for the reply subbed BTW 😀 👍
Looks and sounds mint. when will you be riding it ?
Hi there its not mine my friend took it back home last night
@@2strokemxclassics oh ok are kxs yours
Yeah
Is that a hi flo piston and gaskit kit . Will the new rings bed in without howning the cylinder .is it still going strong . VERY USEFUL VIDEO 👍 .
Hi there it was a customers bike, some ask for dear pistons, gaskets, some ask for the cheaper in my opinion the gaskets from the 60 set with the 2 mains on ebay is just as good as yamaha I've used them years, I just use yamaha gaskets for bikes I'm building and selling as there on vid on here for proof, same with the piston it there in a blue and yellow box it's a hi flo 30 kwid a think yeah m8 it's still running mint av done 3 dtrs on youtube for him he's sold the other 2 but loves his dtx
Thanks for watching aswell m8 👍
@@2strokemxclassics check out my dt re in my vids
OK m8 I'll have a look
Nice 1
Cheers man,👍
Head gasket which way facing up?
It says up on the back of the gasket
I usually drill a hole in the piston at the side just copying the ome one so that the little end bearing is guaranteed to get oil feeding too it has alot of these aftermarket manufacturers dont seem to put the hole in theirs specially mitaka pistons what i use has ive always used them & never had trouble with them.Owes is this dtx anyway m8 forget that bit guess it's your pals bike their is no snorkel on that is their
@@2strokemxclassics reed valve side top below bottom ring just so its in line with the little end wrist pin.& your m8 might of took is snorkel off to let more air in but i wouldn't recommend it has it can put wear marks on the piston buddy & no mitaka dont have the oil feed hole only genuine pistons do m8
OK m8 av have a look at some pistons he wouldn't have took the snorkel off probs someone previous I've heard they take them off for more power a wouldn't bother to be honest m8
@@2strokemxclassics yes it just sounded like it was off in the video if they want it to go faster just put a dt230 lanza one on & ok pal
OK m8👍
@@officialmysteriousrider6327 can you put a dt230 cylinder on a 125 dt engin??
Hi what size piston do the 93 tdr 125 take???
I'm sure it will have a 56.40mm piston as std on that year,later ones have 56mm as std
@@2strokemxclassics cool
That's so odd about the power valve cables number two going to number one
Yeah that's how yamaha made them, I've seen them with cables 1 to 1 an 2 to 2,it spins the valve backover
@@2strokemxclassics I'm going to have to do this job again this week. I have a 57mm bore, do you think I need to file away the power valve cut out??
No m8 57 are OK it's normally wen there 57.4 upwards they catch, wen the barrels off ya can take half the powervalve out and put the piston in you'll see if its missing or gonna rub it, or just leave the valve as is and put the new piston in the bore and spin the valve the same time as you move piston up and down bore and yal feel it catching or not
