well not a good month!

broke my toe! dont ask!

Rear wheel is bent due to loose spokes.

Main crank bearings in the DTR is foobar, have a OUGE amount of play magneto side.

Good news

Have a spare wheel

Got some new stuff today

and the sick engine!

Reminds me of a cookcoo clock, nothin but springs and cogs..lol biggrin

gooner78 · Guru

how much play are you supposed to have on the conrod mine has a little bit of side to side but none up or down biggrin

satelliteone · DTR Senior Member

should be play side to side, (thrust) , but no up and down movement on the conrod.

My up and down movement is up and down on the magneto (flywheel) side case bearing. Nasty!..lol

need to take the cover off to feel that tho .

mind you, i would LOVE to have a full set of these bearings

OOOERRRRRR! but at 250 dollars a go!..lol

The engine is stripped and overall its in brill condition for 20K miles.

Unknown why my left bearing has worn. much more than the right bearing. I have a feeling, in the past, it was run on rather cheap 2T oil.

any how, no detonation. The rings and piston are within tollerence. which is quite good for 20K on standard bore.

Even tho, the plug is running a little lean. This plug has been in for 2000 miles.

Now its in bits, and i have the bearing out.

Ive run out of gas for my blow torch, so i cant get the other bearing out for now..Till tomorra..

just got my new tyre on too today. A vee rubber VM056 4.10/18 31 quid delivered..

satelliteone · DTR Senior Member

well what 2 days i have had. 2 days of banging my head against a brick wall with my engine.

Got the new bearings in, at it took me a day to work out they are the wrong ones.

The bearings i bought are 6305 25X62X17mm

DTR bearings are 6305R1 25X62X16mm .

Would you belive 1mm width difference, u cant close the case!

6305 crank bearings are anywhere from 2 quid up to 11 quid

6305R1 bearings are 21 quid each!

grrrr!!!

Whislt i am waiting, thought i have a go up tidying up the frame. painted up the frame, where the was rusty patches, Also cleaned the head up. The PV valve was chocko with crud and goo. Was a bit tight in turning. all free now.

Hopefully! the bike should be back on the road morra..fingers crossed
. all this nice weather and no bike to ride ..lol typical..

.... · Guru

satelliteone · DTR Senior Member

No probs chap.. be back on the road morra..got some bolts on the frame to sort out first. two have sheered off, where the plasic tail sits. also an indicator on the rear has fallen off the rubber.

Ive renamed the DTR engine.. Yamaha cookoo clock. How they packed so much in it and it all fits is beond me..lol

craigbulmer · Guru

hahaha yeah is quite alot stuffed into there lol its like them flat pack furniture or tool kits, come in perfection, and NEVER go back in not matter what you try :/
id love to know all this about engines lol .. so i could give mine a good clean, to do what youve done id have to pay a garage £300000000000000000 pounds, thats even if they do what you actually asked them lol

satelliteone · DTR Senior Member

well, the bike is back on the road, and ran real sweet for 50 miles over the week end, then it developed a rattle.. cant tell where its comming from tho.. Lookes like either the big end or littlle end.. or a broken ring, sounds from the head area.

SO it back to being off the road, and stripped again..GRRRRRRRRRRRRRRRRRR

any how.. this is a vid this last friday..it was running smooth too!.. and fast..

craigbulmer · Guru

ahhhh .. piss take init....
i like your tail tidy lol good vid
what tail tidy is it?

my bikes making a strange noise lol sounds like summat is loose :S
you can only hear it when its ticking over (to loud otherwise)
its like a whining, like somethings not oiled up or something loose, coming out the engine casing?? ever expierenced it? or heard it?
thanks

satelliteone · DTR Senior Member

i dont know who makes it craig..its all LED..very thin and sits under the rear fender. U can hardly see it. Ive not seen another like it on ebay or in the usual shops. It was on the bike when i bought it..

The one i really like and looks the part is this one..all LED too..

http://cgi.ebay.co.uk/DRC-EDGE-2-LED-TAIL-LIGHT-WITH-NUMBER-PLATE-BRACKET_W0QQitemZ110434912106QQcmdZViewItemQQptZUK_Motorcycle_Parts?hash=item19b66f076a&_trksid=p3286.c0.m14

See if i can get any markings off the one i got... see who makes it..

craigbulmer · Guru

cheers m8, yours does look the best ive seen gotta say lol.
that one looks pretty good, are they easy to install? i know youve not done your DTs one but done anymore?
cheers

satelliteone · DTR Senior Member

funny u say that, i have two other DTR engines sitting in my flat. Both are stripped due to bearings. lol

The tail tidy is dead easy to install. Its held my 3 small nuts/bolts on the rear tail/fender. The wires are easy too. U need to take the seat off ad undo the 4 bolts that hold the fender on. I think the tail tidy uses the existing holes of the original light unit.

craigbulmer · Guru

you have two more engines haha .. what are the symptoms of a broken engine bearing?
oh right gdgd :D

satelliteone · DTR Senior Member

a weird wirring noise craig, and movement on the magneto/flywheel. Up and down movement.

How i notice mine, just now and again i heard a light knock at high revs. Further investigation revealed the play in the bearing. Also vibration at 5.5K revs.. snce ive done mine, it very smooth thu out the rev range.

looks like morra mornin, the engine is comming out again..

craigbulmer · Guru

any video recordings of this?
when at tick over (its too loud otherwise)
theres like a whinning noise coming out of the engine, its a pain in the arse with a helmet on because it blocks out louder noises, all i can heard is that echoing thru the helmet.
its just a little whinning noise coming out the engine, is there a place where its loudest??
thanks .. i hope its not this tho!

satelliteone · DTR Senior Member

should of taken some footage when it was doing it.. soz.. it fixed now..

All DTS have a some type of gearbox whine. it down to the straight cut gears. As to where it was comming from, that was the problem, i could`nt work that out. I just had a suspision of what it was at the time. Left hand side crank play.

anyhow.. see if u can get some footage up if u can.. wonder if i can hear the problem.

Mind u, hope ur having a better day than me, engine out.. pistion fooooorked, bore scored...

The also is a crack going down the center. It did seize on the duel carrage way, Wished i replaced the piston when i did the bottom end now..

nother 80 quid and she will be all right again..back on two legs!

satelliteone · DTR Senior Member

Today a good day!.. the barrel is now bored out to 56.5mm and a matching piston/rings/little end bearing/gudgeon pin.

Fits all well snug, and feels nice n smooth. The compression is unreal. What a difference. The kick starter is a lot harder to move, due to the resistance of pressure. Plug out it spins nice.

I cant wait till ther rings seal real well. 500miles of pussying it around grrrrr..not over 6K either. Run in and the YPVS will be open most of the time..lol

Not happy with the crank bearing.. i think it might need another strip in the future. wont be sure till she fires up.

any one got a brill crank they wana sell?.. just in case

.... · Guru

good job mate, hope thats not a warpy pattern head gasket your using lol, if it is bud hope not teaching granny how to suck eggs lol,beacause they warp people buy genine head gaskets but pattern for the rest is cool just saves that question-why is my coolant expansion bottle running out so quickly lol, it may be a leak in head lol, anyways thought id let you know incase m8y

satelliteone · DTR Senior Member

Yup, pattern crazy, but a very good quality one.. Believe it or not, ived used this gasket twice now, seals perfect. Not used a drop of water. Temps are perfect. My secret is clean clean clean..lol and always check with a steel ruler..

The bike is runing after a few hours install., and jus got back froma 50 mile ride. The low to mid range power is so much more. I can pull to 50mph quite quickly now, with out going in the powerband. Unreal how much difference there is from a 20K piston to new rebore.

The crank is ok, not making any nasty noises, but hoping to find another in the future. glad to back on the road..

.... · Guru

nice1 mate good to hear your wellying it around again, got hook up soon mate, gota show ya the beast lol

craigbulmer · Guru
