As above, why is my bike so hard to start from cold???? It seems to be getting worse lately! It took me a good 5 minutes to get the bike going this morning, it was a nightmare! Once it starts it will fire up first time all day long, no problem at all. When i first got it, all it needed from stone cold was a couple of twists of the throttle, choke on, and it fired up straight away. The bikes an 08 WR450f done around a 1000 miles now, all standard, but has exhaust restrictors removed and shorter throttle stop, other than that, totally standard mechanically. Anyone have any suggestions for me or are they all like this when trying to start from stone cold???? Cheers.
