DT125R FORUM

Sorry if i sound dumb , but can't you take the speedo apart and replace the dial ? print with different spacing and make it to mph

@AndyYam
Well i tried to take the bolt out for 4 days and nothing happened ,only on day 3 did hear the bearings crunching in there , it is rusted solid and a multiple ton press is required or something like that, i even took a rotary hammer and tried to hammer it out to no avail. The oil fittings in the swingarm look like they never been used you can't see shiny metal there at all, so out of pure despair put the bloody thing back together and filtered the oil and it stopped whining , i have a feeling its clutch plates + dirty oil.
I changed the oil at the beginning of this season but it was grey-ish all ready looks like the gearbox won't last to long. I thought about it and decided if i can make it running for the rest of this season i will so i could clean up the garage get some tools some books/manuals, and do everything properly during the winter because i need the bike to repair the bike catch 22.

@AndyYam
How much would you want for the carb?

Well not much progress today, swingarm is still stuck in the bike ,but i managed to free it from the bolt itself now the swingarm can move without the bolt turning with it , it is stuck on the washers near the head of the bolt

according to this pictue, on one of those parts 7,9,5
Fixed a few wires and cleaned connectors on the wiring loom.
What do you guys do when the loom becomes stiff - every wire on mine has insuliaton like hard plastic?

@Calum Thank you !
Good to hear that the pump gap could not have wrecked the engine!!
Which carb exactly should i be looking for? DellOrto VHSA 32ES , DellOrto VHSA 32GS?
They are interchangable so all the rubber parts will fit them both , is that correct?
I was hitting the bolt with a wooden spacer and hammer for quite a while didn't budge, have to try that with a copper sheet spacer.
And since when do hammers cost 50euros ^^ didn't know copper hammers cost that much, wow!
Thanks for the help!

Finally figured out how to post photos :3
All photos

How does one get a seized/rusted swingarm bolt out?

Dont really know how to seal this , i think the shaft needs to be taken out?

How does this look?

And this is my carb, with a broken choke lever...

There is a leak somewhere because a few weeks ago i heard a leak sound coming from the engine , didn't make a big deal about it so forgot about it
This bike doesn't have the oil pump and the holes in this cover were closed but i noticed that the seal was leaking i opened it and found alot of dirt ( the oil pump assy was not there) can it suck sand thru the gear opening?
engine side

I can't find stock jetting online , if you could post them here i would be very thankful!
And because there're no manuals for this bike (as far as i know) i don't really know which one to order ....
No, the exhaust is not too thick and is white colored.
But the scary thing is that it is derestricted , i think the exhaust is from a newer tdr and was cut in half, and alot of other stuff done to it so i have no clue what is factory and what is a botch exhaust
Got the bike stripped so if you need photos from deeper in the engine i can get them

Thanks for the help!

So ran to the garage started the engine and the engine started whining , you can see in the video the weird throttle response. Well no riding for me

Hello every one , new guy here, seems like you've got an awesome forum here!
I have a 1992 Tdr 125r belgarda, it works, but every thing about it is strange, but the most serious thing is the throttle response.
My question is how should throttle position relate to engine speed, because mine does a thing like this when i give very little throttle like 1/7 the rpms start to rise to 7000 or there abouts , and the bike feels very slugish and consumes allot of fuel about 1 liter to 16km.
Hope some one responds !
Thanks
