Hello all. Great site .Ive done some stunt riding in the past and was allways curious about trials..my first trials bike was a fantic and then a pro 250 now im stuck with a troblsome 1998 gasser tx 270.ive been lurking for a while on the site but now have decided to join.

Hello people im new to the site so first of all I would like to say hello and what a great site and source of information. I hope this question is in the right area so here goes. Recently I purchased a tx 270.i test rode it and all was good The bike seemed a good runner and mostly origanal.The bike has a k&n cone filter instead of the original airbox.i brought it for a ride on some local woods and it started spewing coolant from the overflow at the top of the rad.the fan seems to come on when it is supposed to. im wondering would the k&n have anything to do with this issue maybe the bike is getting to much air and is affecting the mixture. any help would be greatly appreciated. ps I have just spent 150euro in trials an tribulations on a new water pump assembly,head o ring,gaskets etc.
