So ever since I bought my 317 I have noticed it has never liked cold weather. Cold starts were always a bit rough, sometimes it would idle funny for about a minute then run normal. So finally back in February I installed a block heater, of course after that is warmed up enough that I didn't have a need for it. A couple of days ago I finally got a chance to try it out. The difference was quite impressive.
- Cold Start @ 28*F
- Cold Start @ 26*F w/block heater
And of course some pictures of the block heater the day I put it in:
