Greetings to all fellow DT owners I have just aquired a 1977 DT400mx for my Yamaha fleet (RD350lc,XT60043f,DT175mx) and I am searching for parts that are missing. It needs. Decompressor cable External decompressor parts Complete throttle and oil pump cable Side panel lock Front exhaust upper rubber bracket Front mudguard extender. Any one who may want sell any of these or know where I can get them would be greatly

Did not look too bad but am going to strip the clutch again and check plates

Just a thought if the steel plates were warped would that cause a judder

because I thought it may solve the problem

Hi cynic yes I did check the basket for ridges,the friction plates are new and were soaked for 24 hours. the bike seems to judder as you release the clutch then grabs .also the clutch cable is new.

Hi All Yam fans I am hoping someone can resolve this one I have Just bought a dt175mx and have found when I pull away the clutch is grabbing on and off as I release it and its bloody awfull.I have changed the friction plates and Springs And it still does it. Any ideas lads and lasses would be appreciated.

Easy to fix just replace the clip behind the choke plunger spring yamaha part number 3531413800 about £1.50 from yamaha

what are you going to replace the rivets with simon

yep I replaced the main thrust bush bearing on the rebuild .it must be something ti do with those main rivets as they seem loose At a glance i think yambits do them for the rds only

cheers kev any idea where I could get the kit.

Thanks Slice the ball bearing is in there but I am going to strip it anyway what a pain in the arse.

Hi all yam fans I have just finished a full restoration on my 79 dt175mx .all was well until the first test ride .when you pull away the clutch seems to judder and also it will rattle when the clutch is released and in idle. As soon as you pull the clutch in the noise goes away. I did notice on the engine rebuid that there is play in the main rivets going throught the clutch basket only when you twist it side to side.there was no ridges or grooves in the slots in the basket either. Any dt fans come across this one

Many thanks mervin I ordered from that site and a good price for tyres

Still having trouble sourcing tyres for this bike i.e Heidenau 400 x 18 and the front tyre 2.75 x 21 which model tyre is it of this make and who has them ?. If not what are bridgestone trailwings in the block pattern like. Many thanks for any help.

Thats a nice bike What about the bridgestone TW24 which has the block tread and will a 4.00 x 18 fit into a 175mx swinfing arm.

Hi to all yam fans I am doing a full nut and bolt restoration on 79 Dt 175mx and have just got the wheels stainless re spoked . now I need to choose which tyres is it best to keep to origional square block tyes if so what make and type and if not what else . What is other dt restorers using any help would be great.

I use fowlers in the uk they may be worth a shot

Thanks for that and it could be a possibility but it seems to be less noise when the clutch is applied.

Hi all just started another yamaha project a 79 french blue DT175mx with 9000 on the clock and dry stored for 20 years.I have installed a new standard piston and rings as bore clearance measured ok ,new gudgeon pin and small end. I then started it up and am getting noise from the clutch and most of it goes away when clutch lever is pulled .is it the plates or the basket thrust bearing or something else any dt wizards out there please.

Hi everyone I am sort of a newbie as its the 1st time I have wrote currently restoring a 1986 XT600 43F and a 1979 DT175MX 2K4 . i have also 2 Kawasaki kh125's from the 80's nice to meet you all.
