DT-R_bradders · Guru

will do m8
if anywon wants to know how and what parts i used to fit the the usd's jusk ask wasnt to hard to do : )

fuggie · DTR Senior Member

i'll bite, what'd you have to do to get the usd's on?

DT-R_bradders · Guru

it wasnt bad but there was one bit that most peaple might find difficult
i used the original dt stem thats pressed into the bottom yoke but i had a one off collar made to fill the gap on the top yoke but had the bottom of the stem turned down so it would fit in the bottom, tht let me use dt steering bearings so tht i didnt have to mod the head tube to get yz ones to fit . and the other issue was tht the dt stem is a fair bit shorter than the yz thats why the fork legs poke out the top of the top yoke also because of that there wasnt enough clearance for the bars to clamp on,but on the yz top yoke you can remove/adjust the bar clamps (not like the dt ones which are all moulded as one piece) so i just removed the bar clamps and put 2 beefy washers underneath to raise it up so the bars would clamp on ill post pics to make it clearer

as you can see in the first pic the stems are quite different
2nd top yoke collar
3rd you can see the bottom of the stem has been turned down to fit
4th you see the problem i had when trying to fit the bars
5th i used 2 head bolt washers from a fiat to raise bar clamps these where perfect size :)
6th i used original top thrust bearing race as a shim to raise/support top yoke
i got replacement bearings from ebay which instead of the top bearing being a thrust type they replaced it with a skinny taper roller makes it alot easier to fit no messing about with lots of little ball bearings getting dropped and lost all over the place ( p-k-n trading. from ebay bout 15 -20 quid)

done a very tidy job of that considering how the tollerances on everything were working against you! did you do the machineing yourself? how did it work out on overall fork length (ie top yoke to axle) compaired to the origional forks?

very jealous looks well good in the pics, need to get some usd's on mine at some point well fed up with the origional 80's forks, they look like their for offroad but then you find the mile long spring spacer...

let us know how they handle

oh and that can is outrageous biggrin

cheers fuggie! na i got my dad to get the machine shop at his work to the machineing for me and make the collar :) and yeah the bars have like 2-3 mm clearance from the top of the fork legs i got as close as i could so that the clamping area on the yoke wer on a flat part of the fork legs coz some sections are tapered. as for the fork length the yz ones are a fair bit longer but some of that extra length got taken up at the top end as its all pokin out the top of the top yoke, when i sit on the bike tho it doesnt feel like im sittin on a chopper lol yea think the hieght is ok dont know what it handles like yet, as soon as i got out for a burn ill update on that, when u do decide to go usd gimmie a shout n ill advise u to the best of my knowledge m8 if need i could probaly get ur stem machined and a spacer made for you if u cant find anywon local to do it for u

oh yeah the can lookin bad ass, cant beat old skool dep lol its loud as fook aswell after i pulled out the wadding, sounds like a proper old skool air cooled smoker lol

fuggie · DTR Senior Member

know what you mean about the noise, i've got a standard can i completly gutted and mangled back together . noisy as hell on it but not actually to bad behind when did a bike swap with my mate, will get a dep eventually like yours but the one with just a hole in the end like i had on my gamma when i was 17, cheers for the offer but i'm quite lucky that my best mates a engineer

DT-R_bradders · Guru

m8 biggrin

fuggie · DTR Senior Member

will do soon, got to finish my tight wad powervalve thingy i'm working on first (them servos go for silly money so attempting to make a setup for a manual advance retard of the exhaust valve confuse

) plus you sound like your going to put them forks through their paces when you've got it finished so wanna see how you get on with the kayabas!

DT-R_bradders · Guru

that power vavle idea sounds gd let us know how u get on wiv that might be interested in doin one myself. yea the forks should be alot better for hair n hounds days that i do wiv my dad n his m8s, jus gotta get hold of a yz front wheel and caliper, axle , and some side panels coz iv seemed to of lost them or somones niked em lol after that all is good smile

fuggie · DTR Senior Member

shouldn't be to hard to pick them bits up, i'm not the only nut who got one of these for a bit of enduro then biggrin

DT-R_bradders · Guru

yea just trying to find them cheap as i can as money isnt tht great atm, ah m8 i love enduro u cant hoonin round with like 200 other bikes all at once its great! and green laning is pretty kl aswell biggrin

firdauz8 · DTR Member

i would like to know you are using dtr hub or yz hub and the brakes too.. thanks..

DT-R_bradders · Guru

im goin to use yz wheel, axle and front caliper to fit the forks m8 iv got the dt wheel on there atm jus so i can get it off the stand and see how it feels when i sit on it, height wise.

sorry it took so long long to reply m8 had a lot goin on atm

firdauz8 · DTR Member

Wow.. I've checked thru eBay and it's gonna cost me a lot including shipping.. I dun think I can find any Yz parts here in singapore.. Even dtr is almost extinct here.. I wonder if wr200 top end fit wit dtr..

DT-R_bradders · Guru

ah m8 thats ****e good luck in your search for parts, prob better to go standard yz yokes tho be alot cheaper! alltho those yokes would look the dogs nads biggrin

as for wr parts your jus av to get a set and av a play about wiv em see how it goes m8

DT-R_bradders · Guru

bash plate... the next mod along with shorter rear sus links biggrin

fuggie · DTR Senior Member

that plates looking good, hows it look on the frame? a idea for ya, my mates kdx has two loops welded on the frame as standard that come off the bottom rails out to the side to protect the engine cases, thinking of sticking something like that to mine then bash guard over the top

SUPERSTEVE · Guru

Where did ya get the bash plate from?

DT-R_bradders · Guru

yea i know what u mean my dads got one only thing is thos loops only protect against big stuff hitting the engine but not not stones n other crap like roost wen racing in enduros ect , plus i dnt think theres a lot poking out from the dt engine spose the water pump does a little bit but not to bad. what im gonna do is make it so that the bash plate protrudes either side of the frame and covers the width of the engine to offer better protection also gonna get some sump gaurd foam u can get from most online mx shops to cut to size, mainly for the holes at the top end of the plate jus to stop crap getting in. also in the pic if u look closely u can see iv marked a section to the right hand side thats roughly how big it needs to be so i can make two guards out of this one plate. when iv got one to fit my bike ill replicate another to fit aswell n maybe sell it for a couple of quid with all the fittings ect needed to fit, to another dt owner wink

robbed it from my previous employment at a main dealer garage shortly after i got sacked, nabbed it as i was getting my tool box outta there after every one had gone home (apart from sales dept, i didnt break in lol) along with a bench grinder that wasnt bolted down..cheers! haha

Yeah id be Interested, are our bikes the same underneath? mines an re?

DT-R_bradders · Guru

ite kl dont see y not if not i can always pop round with it n av a quick measure up since u only live down the road lol

fuggie · DTR Senior Member

good idea with the foam, read in tbm a while back its what the proper race teams do as it weighs less than having mud stuck under there

thats exactly y im doin it smile

, bit worried bout it soaking up water wen im usin it on the road tho, could weigh quite a bit then? was thinking stick some flexible plastic over the foam jus behind the three holes at the front to stop that ? see wat happens

jack_p92 · DTR Senior Member

think im going to make one of those bash guards, got some scrap metal laying about at work somewhere.

You a bike mechanic then or car?

CooS · DTR Senior Member

Yamaha do a bash plate guy's. I priced one up a while back, it was about £30ish and they look the bomb....

Any bike dealer can order them in for you i think ;)

Pic (they do black or silver one's) biggrin
