hey, I have a 250cc bike... a FZR250 to be exact. It is a 4 cy / inline 4.... I rode it to work this morning and it sounded fine, but when I came home today, it seemed like it was only using 3 or 2 cyl. It was VERY sluggish from hills and had a mean low growl to it... normally it is very high pitched whine. Do you think it could be the spark plugs that are misfiring or a carb issue? I just need a little help from the bike tech all-star guys on here. Thanks.
