Re: loss of power in cold

How long did you ride for? I assume you've checked the oil, when hot, with the bike level. Is it hard to shift when stopped? (That's normal - try letting the clutch out a tad - to just at the friction point, and applying some shift pressure - it should drop right in.) It sounds like something is wrong with the carburetion - air flow, fuel, spark - did you check that stuff?

Are you riding with the choke on or off? Is it backfiring? Does it stall?

How long has the gas been sitting in the tank? Was the tank full when you put it up for the winter?

If you are REALLY going to ride the bike in the winter time, you REALLY should consider a synthetic oil with a first number of 15 or below. Mobil 1 has a good one, labeled for Sport bikes.
A little pricey but very good.

Except he has no appreciation for riding a bike when it is REALLY cold; like it is here now.......20 F. with snow and 30 mph winds !!! :biggrin:
And it's not much better than that in St. Louis either.

Note: No I don't ride when it is cold. 60 F. is about my low point......and it appears that might be the low point for the GZ too.

Re: loss of power in cold

If cleensmoke responds to any of AC's inquiries, the real question is, can AC answer any of them?
My bike starts and runs fine in the cold, but I hate riding in the cold, like in the 50's with the wind - have to put on so many layers and gear that sometimes it's harder and longer to suit up and undress than is the ride. I feel like a little kid all bundled up to go outside and play in the snow. Hey, that's an idea - maybe I'll just put on my snowmobile suit and try that. Too bad it's not armored. And the color doesn't match my bike.

I have rode my GZ in the 20's so you figure with the wind chill it was lower than that, and it ran perfectly (except for my teeth chattering). But no snow of course, and definitely no 30mph winds.

"Ran perfectly" also means that you had no trouble getting it down off the "choke" without uneven idle and/or a bit of stumbling ?? If that is true, and you are bone stock, then it appears that your are lucky indeed.

Re: loss of power in cold

By perfectly I meant "ran like it does when its warm outside", in other words I didn't have any unusual trouble with it like Cleansmoke is having. I quite possibly had it on choke longer than I would when its warm, because sometimes when its warm I don't have to use the choke at all, but no stumbling or anything of that sort at all.


And yes other than a Aftermarket air filter and Rotella oil, Bone Stock.
