i dont see how this is possable, there may be vibrations but no more than you get at 10k revs in 6th doing 80mph. almost every modified dt is apsalutly fine and noone ever really does anything with the clutch, especially the bolt. when you get it back again just check yourself that the bolt is tight, but dont tell them your doing it because it could unwarrenty any work they did

thats yamaha for you. enough said? :D haha. tbh, it was probably a mistake on there part. most mechanics do half-arsed jobs at some point in there life...

hey guys

whatever you do dont weld it ~(if you weld it you will unbalance it...not good) cry

if it is getting loose ..take an airline and blow all old oil off adjuster nut

put lots of locktite lockthread on the threads then adjust it and let it set before you put your oil back in

hope this helps

yeh they probably let oil get all over the thread and nut

xGINCATx · Guru

What i did was just tighten up to where i wanted it and put a locking nut on the outer thread that poked through, never had a problem since i did it..

GADGET · Guru

hey gincat do you mean a second locknut????

or just one nut ???

just so i know as this sounds a very good example aswell

cheers fella smile

Well when i took my clutch off to put a kickstart onto my DTRE it kept doing as PatMan said and after 2 cheapo gaskets i thought fack it just put a lock nut on the end
There was only 1 thing on the pushrod at the time, and that was the big flanged nut thingy, you know the thing you adjust?
Well everytime i went out the clutch would spin around as it's supposed to and slowly but surely i would lose my clutch (well not slowly but after about 3-5 miles)
So i stripped it once again and set the pushrod up, by the good book (haynes not the bible lol) and put a locking nut on the outer side of it so couldn't un-thread itself

So in the end the pushrod had the big flanged nut thing on the inside of the pressure plate and the locking nut on the outside of the pressure plate

Like i said it worked fine ever since biggrin

GADGET · Guru

the locknut was supposed to be there from the start lol

this comes loose and gives the probs...yours must have come off cry

did you put threadlock on it ???

PatMan · Guru

Thankyou sooooooooo much guys for your advice, OH MY GOD @ Gadget mate when you said dont weld it, THAT IS EXCACTLY WHAT YAMAHA TOLD ME TO DO IF IT CAME LOOSE AGAIN THE ********, BUTTTTTTTT one of my biker mates said about the lock nut, so you lot are deffo right there, I went for a blast last night on it, and thought it needs to be thrashed abit, (as again YAMAHA told me to keep the revs lower) so gave a good 9/10k revs here and there, and touch wood its fine at the moment, the mechanic in the shop said I have now tightened the pushrod nut up as tight as it will go.......AWWWWWWWWWWWWW so you didnt bother doing that first time round then I take it, he knows and I know he didnt, hence why it was free of charge they just didnt wanna admit the mistake, which in my eyes he would of got alot more repect if he admitted the mistake, NEVER WILL I TAKE MY BIKE BACK THERE TO BE FIXED, they obviously dont bother with torque settings etc etc they just guess, as other bolts like my plastics etc etc were not really tight either, but thanks for everything lads.

I am just taking alittle time out from the bike stuff at the moment, as its just been one thing after another with yamaha and my bike over this last month, but I am still about

Oh thats probably why mine kept messing up, i must have took it off and didn't realise (highly likely)

Instead of the original which doesn't have a locking nut on i used an actual locking nut itself, you know with the blue nylon but inside the end?

And no worries PatMan, they probably know there stuff but for other (bigger) bikes, can't see all that many people taking DTR's in to be sorted as if you have a decent one and keep it in check with the maintainance then barely anything will ever go wrong..

GADGET · Guru

ahh a nylock nut very good

that one should last you a while as even when its not tight it will stay locked smile

PatMan · Guru

Seems to be fine now, but at least I know now what to do if it happens again, thanks lads for everything

and GIN mate, When I originally rung up Yamaha they did say to me, we have a mechanic here who knows **** loads about DT's........Obviously not hahaha

PatMan · Guru

I think I found why mine had an air leak when it did, on the pic below I have put arrows on the inlet stub at the bottom where there is a thick rubber square bit, the person before me obviously cut it out to get more air in, I take it this is not a good idea at all???

xGINCATx · Guru

Some people have posted positive results by 'chamferring' it down, myself i found it didn't do jack $h!t!!
If anything it slowed it down so i put the original one back on and sold the other on ebay for twice the amount i paid as a high performance inlet manifold!! wink

PatMan · Guru

Well just to let you know gin mate I ordered that one above, of a 93 dt

you always seem to be right so I take your word for it

and will stick that one on when it comes

thanks again mate!!!!!

xGINCATx · Guru

Yeah no worries mate, thats going on personal experience alone though
Someone on here (for the life of me i can't remember his name, something about yz or yzf) well anyways..
He did some mods to his bike, such as cutting the top of the airbox off and upjetting aswell as the inlet manifold mod, i think he said it worked but since he did it with all the other mods at the same time it would be hard to tell which helped and which hindered the bikes overall performance..

How much did you pay for the inlet manifold then? I think i paid £10 for mine with the standard reeds aswell,
Then after finding out it didn't do all that much i sold it as a modified inlet for £15 and the reeds seperate for £5 haha

PatMan · Guru

Hello mate got it for 17 quid including postage, which I know seems alot but I thought sod it get it while its there

xGINCATx · Guru

Yeah it's all about supply and demand, if he was the only one on ebay selling one then he can ask whatever he wants until someone cheaper comes along..
Sell the other as a performance inlet manifold and you'll easy pull £15-20 back for it
Perfect for some 17yo yob* who will get the money off of mummy or daddy

*When i say 17yo yob i of course don't mean any yobs on here who happen to be 17 wink

PatMan · Guru

hahahahahahaha mate funny

bkray · DTR Senior Member

im 17... someone say PERFORMANCE inlet manifold? >.> amggggg, i must get it!!!

xGINCATx · Guru

See PatMan i've sold it already for ya! How much commision do i get? wink

tripr · Guru

hahaha well funny

PatMan · Guru

Hmmmmmmmmm you did well Gin, and of course I would sort you out for doing it, but the one I got on at the mo I would throw it straight in the bin, as it coursed the air leak, (so Yamaha say) and they have used seal stuff around it to close it up, so what you reckon its worth now mate?? nothing?

GADGET · Guru

hey there guys

part of the rubber bit is the sealing lip and if this gets cut off when modded you will end up with the air leak

you can sort this by putting an extra gasket on the sealing side

good luck

PatMan · Guru

Thanks Gadget mate for the info this is exactly what I have done, but got another one how its suppose to be

GADGET · Guru

no probs man

youd be stunned at some of the bodge jobs previous owners do to these bikes

i bet this aint the first one youve had to fix either lol

your one is gonna get you throo for now but atleast your puttin it back as it should be

PatMan · Guru

Yes mate very true but thankyou for all the info

PatMan · Guru

I did notice aswell when I took the reed block off there was a black gasket there when I took that one off I noticed there was another black gasket there aswell, and I did think that was odd 2 gaskets on top of each other when there is only suppose to be one underneath the reed block

GADGET · Guru

hi there patman

i mean one either side of the reed block or it will still leak

hope this helps
