first ride and got problems!

ToySoldier · DTR Legend

2 questions mate 1 is your bike been turned premix cos dts are auto lube and 2 do you have a standard pipe?

Jace · DTR Respected Member

the lad i bought it off said he always pre mixed as oil pumps are ****e! pipes suposed to be dep all through but it dont sit right on the bike for my liking it touches the front plastic (same one as in your pic with dt & ride on) havent gone over it properly t see if theres a makers stamp on it!

ToySoldier · DTR Legend

just rembered you uploaded some photos ill have a look

ToySoldier · DTR Legend

ok has a dep back box but the down pipe is a bigone and tbh that's one of the problems as there pants

and from your photos it has the oil line running to the manifold so check the bottle on the front right see if there's any oil init just incase as to much oil will make it puff like a gooden and bog out/ make it foul the plug after a few rids

and you have no powervalve servo so id say it might be pinned shut. try opening it and go for a ride will make bottom end boggie but top end should be alot better

Jace · DTR Respected Member

bottles empty,starts up 1st kick ticks over fine has the top end misfire and clutch rattle to sort and it should be nice bike! might have to bite bullet monday and get front dep,clutch being stiff could the ball bearing on end push rod be knackered?

Might just not be setup right. Wrong oils or no oil can cause problems. As well as too much gearbox oil.

ToySoldier · DTR Legend

get a gutted standard mate much better then dep and there's a lad on hear selling some

hated my dep tbh rusts way to much and if you drop it and scratch it you will cry hahaha

Had my DEP since December and no rust so far. But agree about dropping it. Once this pipe looks ratty I'll get a arrow full system me thinks.

video of bike running clutch in quiet,clutch out noisy!,power valve on standard setting turning whilst running has it hitting piston,so bored out quite far?

MDK · DTR Legend

Are you sure you turned the PV the right way mate as i thought it only caused problems with powervalve hitting piston when the valve close's off not pinned open?

Jace · DTR Respected Member

i was turning it playing to see if was open or closed and could hear it whackin piston when went to far!

NEV · Guru

Theres a centre pock mark on the end of the powervalve, if you line this up with the two pulley casing bolt holes, your powervalve should be fully open.
The centre pock mark should be at top left of the diamond shaped end btw.

Jace · DTR Respected Member

Cheers its been about 23 yrs since messed with powervalve,more used to diesels nowadays lol

tripr · Guru

sounds like big one front pipe performance you got there if your runnin it without a powervalve servo close it off slightly so you can see about 2mm of the powervalve up the exhaust port ,, kill the power loss in the later gears for you

and the clutch isnt holding an trying to drive the front sprocket still by the sound of it . try new tranny oil first but new clutch plates will probably sort it altogether

dont think it should sound like that!

What does the bike rev out at? Could be the reed switch on back of clocks... Bought my dt with full dep and was told it was fully derestricted (snorkel removed, full dep and jetted up) only to find she would only pull to 50ish then it was hard work to get anymore put of her!!

Quick check, take off light shroud and light see if there is 2 wires going into the rpm clock just pull them out and there should be a Reed switch on the end of them (looks like a plug fuse) tape it up and tuck it to the side!
Basically I think the reed switch retards the powervalve @ certain rpm.

I can't view your video to give any advice on other problems (am on me iPhone)
P.s answer you pm please pal waiting to organise courier

Cheers
Ken

id say clutch plates mate there easy to change ,,, iv got a pv cap sitting in the drawer to with a removed dowl so it can be custom adjusted

Jace · DTR Respected Member

I got some plates outve other engine i can bung in to test it,of course they could be equaly as knackered!

MDK · DTR Legend

plates -reeds - zaust could all be fine could all be to down to poor settings by the last owner . just og over the bike checking everything is sett ok things like cables chain tensions - air mix screw settings - not sure if it has a reed switch ? check and tighten if needed all seals and bolts inc engine mounts lose engine mounts can cause vibration and make you think bearings are fcked . think you removed the pics in other post ? what end can has it got fitted ? . is there any boost bottles fitted front or back of carb ? . all the usual service type things .

also when ever you buy a bike dont take the sellers word on anything .. change the oil instantly also new plug and clean or replace filter .

Ralzy · Guru

Possible main shaft bearing or gearbox bearings are gone as it doesn`t sound healthy at all.
Gonna require engine strip & rebuild

Calum122 · Guru

Omg. That is not rught. Sounds like the seller knew about this hence price...

Unbelievable some people.

Jace · DTR Respected Member

hes very sory,but when asked him for few quid back towards rebuild he suddenly went quiet,but hey ho hoping to find someone to rebuild it for me,ill order full engine,gasket,seal,bearing kit through link on here,source g/box bearings and get job done once properly !

benjarminx · DTR Respected Member

happened to me a few weeks ago mate, sounded exactly the same to!
and it was the output shaft bearing i just put new bearings in throughout and it solved it.
hope you can get it sorted!

MDK · DTR Legend

I would be pissed but this do.s show the need to test ride and or if not possible ask for a video with date showing it running and how it sounds .

and would be thinking of asking for some money back as he did say well here are his own wrods on the abay listing . high lighted the key points that should have said more like there is some engine noise and maybe ready for a rebuild .
.......................................................................................................................................................................................................

engine was nice quiet,started with your hand,but 35 miles later it was ratling like in the vid axl did on his phone,lumps outve frame now and awaiting a pm back from norfe lol
i got an email addy of him and found him on fb as ebay get tetchy if think your costing them money by dealing off there site(which i did,but theres no buyer protection on motors section)

dread123 · Moderator

started with hand, obvious signs of low compression...should have been warning there pal...anyways you'll soon get it sorted..I did with mine-that was a mare! but all done now

MDK · DTR Legend

did you already leave him feed back ? always pays to wait a week or two with any ebay buying no matter how fast it is posted always hold feedback till its tested good ...

then give bad feed back to warn others they are not to honest with descriptions
