2005 pro 250. I have just polished the inside of my top hat and fitted new o rings and was after some advice on the best way to refill and bleed the system. is there a special lube to use on the new o rings? do I fill the top hat first?

What about a 360 ?

I think I will be joining Ipswich MCC soon, a bit more practice first though as I dont want to make a fool of myself. The Woodbridge club seems to only accept pre 65 trials bikes !

I am new to trials and have been practising on my gas gas 250 pro for a while, and will soon feel ready (brave enough) to enter a trial. I was wondering which club would be the best in the woodbridge area to join for trials.

Is it normal for the rad vent pipe to release some pressure after riding for a couple of hours ?

Perhaps I am just paranoid. but is the fan supposed to suck air through the rad or blow onto it, mine is sucking air through.

I removed the rad cap, started bike and could see the coolant swirling (a lot). with the bike idling the fan cuts in after about 5 mins and runs for about 15 secs thens comes on and off periodicly. could it be possible the fan is not coming on enough? When the bike is hot there is pressure in the rad when I unscrew the rad cap. Could it be the timing? the bike runs well with no backfiring.

Thanks for your help pandelboy I will try this tomorrow

Hi everyone, I am new to trials and have just got myself a 2005 txt pro 250. After riding it for about an hour I can hear a hissing/bubbling noise from the rad is this normal? The fan works ok, the rad is clean and full of new coolant, the bloke I bought it off had recently fitted a new water pump. The bike runs fine with no engine noise, starts second kick. any advice would be much appreciated.
