So as i have a new bike and all i've had my mate riding my old cbr250r which has served me well and was still running like a champ despite minor heat issues and blowing a little smoke. as it was time to service her my mate put her in at freestyle honda in frankston on friday morning and got the service and asked to check out the smoke issue. got a call back this morning saying the service would be done and the smoke was due to a head gasket (which is what i had suspected, they wanted $500 to fix that so pass ill do it in the next week or 2 as he's away on business) they serviced and cleaned it by the arvo and I drove him to pick it up. when i got home found out that the bike was running like shit and that it had stalled in third aproaching a speed bump around the corner and it wouldnt start again lights were on bright but the starter just spluttered i push started it and noticed straight away that it felt shit, i cant quite explain it or how it felt but deffinately not right and completely gutless...for the bike... which was his description too. How do i approach this with the service agent? for one the battery is only 12 months old and was 100% before it went in but what concerns me more was how it is performing now compared to how it was performing before it went it. seems like woulda been better not to be put in, could them washing it with HP hose have done anything or could they have ****ed it up with a simple oil change?
