cold engine vibration?

[03TBUSA]

So temp was up to 50 the other day. So took advantage and took the beast out for a stroll.
It's been freezing so haven't started her in about a month. Started right up but engine was vibrating pretty good for the first 5 seconds. Then everything was back to normal. It's never done this before. Anyone know what could have caused this? Stock 03 with 22k

Vibrating, or just making noise?

Mine makes noise on cold startups, I believe it's the cam chain tensioner. I've never had a Suzuki that didn't make noises. ROFL

I also shake a bit when you wake me up and I'm real cold.

I always though it is just the ECU making the mixture slightly richer with a cold start, until corrected soon afterwards?

Could be a cam chain slapping, the tensioner is based on oil pressure I believe, so until pressure builds up..

No noise, just vibration. Nothing normal for sure. Guess it's just the cold ass temperature
