Hi guys, hope you al had a good christmas.

I've had my Raptor out over the holidays and Ive found its not the best for starting when the temperatures cold, to give you a rough idea temperatures of 5degrees c etc. It eventually starts on the choke but then wants to cut out. Once its run for 5min or so its fine, starts first time no problems, just the initial starts a pain.

Also as a side line, how do you raptor owers find your front brakes, personally I think mines are very soft and dont stop the bike that great, Im sure when I got the bike they were better but then I could just be inagining it.

Cheers

Dave

 

Mine coughs a little when its cold but once she is warm it runs fine\ i am happy with my front brakes if anything i use them too much!

 

My cousins Raptor has the same problem. It was in the negatives the last few day and couldn't get it started. Not even when trying starting fluid. Any suggestions.

He has the CT Racing pipe, jetting, and airbod mod with Proflow.

 

Check your valves, I have seen them tighten up and cause terrible problems in the
cold weather!

 

thanks, didn't really know that the valves could tighten up on their own

 

If the Raptor is mechanically sound, then it should start right up. I ride year 'round and have never had a starting issue. Proper use of the choke is key upon startup. Apply enough choke so the Raptor idles highest. THen, as it warms up it will start too shutter....let off the choke a bit and the engine rpm's pick back up. Follow this procedure until you have no choke applied....piece of cake...[img]i/expressions/face-icon-small-smile.gif[/img].

 

He bought an 01 raptor and has had it since it was new. It's always been tempermental to start. Your are right that it has to be started just right. But with it being so cold out it just doesn't fire. It turns over strong.

 

I keep up on the valves... we rode at Tower this past sunday, and when we got there it was 1 deg. F. I had put it on the charger in the garage the night b4. It started on the first try after about 3 revolutions. After eating lunch and it sitting for about 30 min, and being about 15 deg, it started again with no problem.... I dunno, maybe throw yours on the charger too, seemed to do better than my buddies bikes too... 1 Z400, another raptor, and a YFZ.

 

I use this same procedure, and I have never had starting problems with mine. I live in Minnesota, so I have ridden it in a variety of conditions, including below-0 degrees temperature. On a side note, what does everyone think of the choke set-up on the Rappy compared to other quads, like a Predator's dash-mounted push-pull system? Personally, I like the Yami's set-up much better.
