ok. well im ordering the new sprokets now if that doesnt cure it i will opent the bottom end. take it i will need to replace 2nd and the binding gear to it? how would i go about checking gear selector or anythink else prob wont be that as stays in gear ok. ill just see what the outcome is with new chain and sprockets should be here within 2 days. was thinking of selling the thing soon as well just booked in for mot i have done nothink but spend and maintain this bike just get it running perfect then slap an new adventure headache lol anyone no if my cylinder head will work with the older mod bottom end(kickstart model) might look out for 1? thanks anyway apprectiated

would love to know why that clicking noise is there its only in second gear .really cant see what the guide inlet could be doing it slots back in lovely its like groves it sits into.

im not 2 sure weather i will as theres no cracks or bangs to the main cases just the top guard bit was going to just leave it as it will mean splitting the cases i think because the bit thats broke is not on the main case im think from memory.. so not much i can do except a new LH side crankcase. like i say i hope it will be ok as i cant see damage to the main engine case.

so what does that do then mate? doesnt look like much

it kind of looks like number 8 http://www.oemmotorparts.com/oem5.asp?M=Yamaha&T=DT%20X%20%20125&Y=2005&L=YA-DT-X-125&O=CRANKCASE%20COVER&F=YA-DT-X-125_AK&L2=YA-DT-X-125_AK not to sure but that looks the same size as my broken bit but im sure mine is in 2 now so would of been bigger im confused. they call it a guide inlet any one any ideas what its use is?

so would that be the problem? i did check well wiggle the sprocket seemed tight..ps hopefully u dont think i mean that plastic bit that had broken it isnt ill try see if i can see it on the parts diagram the pic above has an arrow the piece sits just infront of the sprocket faceing towards the bike.

l lol ill try get 1 up asap. its like a black piece of granite plastic hard to explain right behind- infront of the drive sprocket.

anyone reccomend a good chain sprocket kit? was looking at the did chain the double o type for 40 kwid

the chain was loose i think. would that be the reason its makeing a noise in second gear like kind of jumping? the sprockets look fine no worn shark teeth and aalso looked all over chain seem fine.

alright fellas got a wee bit of a problem with the dt125 . had the bike out yesderday for first time in a few months ,was stored in my garage after a service new coolant oil ect.. was strated every week just to keep the old engine lubed up nice. so too cut it short i took her out gave her a few laps round my way and then decided i would hit a trail not to far from me for a bit of crack!! (crack all right) as soon as i hit the dirt gave her the dig and held her on a nice weelie in second to 3rd. repeated the same and snap crack wheel lock up engine died silence! so i was stuck on my own no signal on phone were i was brilliiant... looked down the chain was of the rear cog and wedged between the bolts of the sproket. chain still intact not snapped. so i manage to get it release it wasnt half stuck tho rolled it back onto the sprocket drove it straight home 2 mile slow as i new my chain must of been loose.and i could here it clinging and wacking on the swing arm-chain guard . so straight into garage on the stand checked all over chain fine sprockets fine. but looked closer and saw the dreaded sight of broken engine case no damage to the actual main cases just the wee cover on top behind the chain guard on the engine now i do its there it looks a right sight but as i say didnt crack engine thankfully. but just rount the front sprocket there is well was a kind of black block that slid into behind the fornt sprocket not to sure what this is but its in 2bits on my kitchen side. so put the chain all back on checked all was right alligned chain ajusted right hit the road and noticed in 2nd gear it would judder from the back wheel and like a clicking noise, so straight home wheel of checked all bearings axel all fine. so what could this be...???? im thinking second gear fooked as i cant think of anythink else other that new chain sprokets but dont want to go get em and realise they wasnt needed.. so any input would be great hopefully someone no of or has experiance this before... and if so it is the gear. them bottom ends hard to do? thanks in advance people.. dluke

yea mate thats why ive given up on this one now it all looks right set up wise.(just found how to zoom on the page now ) im going to just bleed it tomoro do another 100 mile and if still guzzling 2t ill take it the shop monday im going to have to leave it with him so god nose hw long it will take to find the problem. but ill give him hes dues he will go through everything with me and helps as best as he can lol like i say its just the money sitiuation. and whats that saying "time is money"

have one here mate but cant make it out for the life of me its a pdf file so very small pics imgoing to leave her now and pay for a good look over it god nose how much but i no it wont be cheap lol 30 kwid and hr labour but at the same time im dying to get my head around this bike to be able to look after it myself ..kinda a hobbie to me now keeps me out of mischeif and from pissing my money away.

cheers mate, just back from a ride there. no problems going ok rideing wise not too sure about the 2stroke tho i looked before i went and i only done say 25 mile and i can say i can notice it used up a bit (should of marked it ) " I'll take some pics of mine and of the procedure in my Haynes manual tomorrow morning" << that would be highly apprectiated dude thanks a million!

checked transmission oil looks fine right amount but thats it cold.. i did drain a wee bit and it looked cloudy-dirty.

its always been heavy on oil i thought compared to my brothers, never hear him saying ive been for oil much were as me nearly every week, lol

cant really see at the minuet ill need a good broight tourch as i can not see a reading in the window..(please....please not be full) would that be a big job 2 sort out? yea see what u mean about when i adjust it, im going to check this oil level in transmission first! if all ok ill just do another spin out and see if it has cured it fingers crossed!

its the re model, ill be checking soon to see if the older mod is the same, but as airhead said hes looks different so ill report back hear soon, asked a few machanics today and no1 can put ther finger on it or give me a reason most just said do the premix but i defo dont want to do away with my oil pump it makes sense to keep it..

only just home from work mate ill have a look shortly. cheers pal

would it be different from the older model 2000 as im able to check 1 all i can do is see if it looks to be in the same placce. that is if they are the same??

no worries pal ill just see if she runs any better.. high hopes but...otherwise will have to go to the garage theres noway it should be going through that amount of oil..would of thought 4 tanks atleast to the litre of 2t

and thats the cable bit i adjusted http://s1011.photobucket.com/user/dtluke/media/1383296_663052290394554_812401377_n_zpsfb416050.jpg.html
