Hi, This is my first post here so Hello everybody !! I'm pretty new to dirt bikes, all my life I had sports bike and last year I decided it was time to sell my precious CBR954RR and get an MX bike in the shape of the 2002 Yamaha YZ426F. I have it for a year now and I only ride Enduro/Trails but I have a problem since day 1 and was wondering if its normal...My bike seem to lose coolant everytime I take it out, I usually fill the radiator all the way up with antifreeze but I noticed that everytime we rest the bike is wet as the water are coming out of the relief hose (the one where the cap is) I checked all the hoses and there are no leaks. Is it normal that after every ride I have to fill the radiator again? My father told me it may be a damaged cap but I can't just buy one as it cost here in Israel something like $80 !!! Also, I read that there are some 1.6 caps out there but I'm afraid it will damage my engine as the original state 1.1... Any thoughts?? Thanks guys !!
