A forum for owners of Yamaha TTR250 trail and enduro bikes!

I'll write it again because everything is lost in this thread.
What i've done this winter on the bike
Changed oil and filter
New oil Fill cap
Installed Tubliss Gen 2 on both wheels,d952 front and d606 rear tires with sealant
Rebuild Shock,shock mounts,swingarm linkage and forks
Replace control cables with longer
Sw-motech 30mm risers
Rebuild calipers and installed new pads
Added fuel filter
Opened carb to clean it ,but wasn't needed
Replaced the rhs with a unit from a zx9r.Redid some wiring and used 2 relays to power the headlights.I now can run both low and high beam on when needed,and switch them off.
Added a usb charger.
Most parts bought from totallyttrs.


The shock had one shim less on the rebound side.I forgot the base valve copper washer on one fork leg,it doesn't leak yet.
My fork base valves are not adjustable as they should be.
I took it for a ride and now i have a nice responsive suspension!
I found out that it has an oil leak from the head gasket!Should i just replace the gasket or is there something else to check?
Some pics and a short video

That's looking very nice, Spyrious.

But why would you want dip and main beam on together?

The video shows that Greece has some nice trails. Perhaps a little dry but there's nothing wrong with that.

In Devon we've had about 3 storms - one after the other - and rain every other day.

Some nearby counties have been flooded for weeks - no dry trails to follow at all.

 Thanks!

When i had them only low or high beam on,i could see that well.And because they are low power leds,they do not cause any problem.

Yes its dry.In the last years it has some long dry periods with almost no rain at all,and then it rains in one day what in normally rained in a month.This winter was very calm ,too little snowfall also.

If you're gonna change the gasket mine as well go all the way and put in at three fifty kit!! Hehe!!

Oh, nice bike!!

Your bike is looking smart and the parts are already on their way

Another video.This is my first attempt at fitting tubliss to the rear tire.It was a very painful task.I thought the front would be easier,but only slipping the rim inside the tire was easy.I don't know why i struggle fitting tires on the ttr250 rims.On the 990 it is easier for me.

There are two compression rings and beneath them is an oil control ring.

Looking at your photos there seems to be a ring there - the little depressions around the edge - have you tried sliding the ring round with the tip of a little screwdriver?
