I would look at the water pump...they tend to snap...you won't know it's broke till the engine gets red hot like you said or the radiator pipe goes bang with the pressure.
Rebuilt an o7 250...put a new dph clutch why we were at it.... we then added atf oil and it made terrible noise...after racking our brains thinking we put something back wrong we noticed on the clutch box a big white sticker stating "do not use ATF oil !!!" put normal bike gear oil in and it's all fine no noise
Engine had an annoying "rattle" turned out to be 2 bearings knackered in gearbox
Put everyithing back together new bearings in gearbox new piston new clutch etc.
Started bike up...there is an annoying rattle coming from the clutch area...when you engage gear the noise goes...when you pull the clutch in the noise is still there it only goes when you engage gear!! We've checked the clutch basket etc and everything seems to be fine.....any ideas before we strip it down again? arghhh!!
Which is what I did...I didn't just go and buy an Ohlins I tried two shock repairers and both said the same thing...you can bodge them but the chances of the gas staying in is very slim and for
thanks very much, i'll try them and i'll see if i can source a cheap used one
Hi..your have trouble finding one I looked everywhere...there not servicable!! gas leaks out and thats it...I bought a new Ohlins from Thor motorcycles in Cornwall the guy there Colin was very helpful and knows all the faults etc even sets the spring up for your weight...not cheap to replace but worth it...and it's servicable
How are you getting on with the beta now? yes i find it heavier but i'm thinking it's got more to do with the engine characteristics as the gas gas had a more revier engine and the beta feels more tractable...will see how i get on with it like i said i've only been on it once so early days
Just sold me trusty old gas gas 280 and bought a 2005 beta 250...wow what a differance! anyone got any tips as i'm struggling a bit on the Beta...mind you i've only been out on it once
Got a gas gas txt 280 yr 2000...need some advice on fuel mixture...been putting 125ml to 5 litres of fuel 40-1...my friend said gas gas like more oil as he runs a beta and says they need less? so a bit confused...i'm guessing by reading some posts that i'm running the bike too rich?

Check the water pump...it's usually the problem when they get hot...little spline snaps of...
