How does 30 mph sound?

Ok, I'm on the second tank of gas in my new ring and hone break-in. I hadn't brought the bike to full throttle yet, but, I thought that it was time the rings saw just a little more abuse (my oil pump works, and I'm also running a 50:1 premix in the gas, just so things stay lubed for the break-in). I had previously only brought the 1986 Spree I fixed up to only 24 mph on the first tank of gas. Well, it hit 30 mph without a whole lot of effort, I noticed that after 26 mph, the acceleration about cuts in half, I'm guessing I'm hitting the empty RPM's. I barely held it at 30 mph for more than 3 seconds, but it felt like I might have been able to squeeze one or two more mph out of it.....I guess I'll find out after it's been broken in all of the way.

I'm glad I got an '86 Spree, from what I've read, the '85 and below could barely hit 26.....

I'm still having some cold start issues, though. It may be related to trying to start the bike after it's been sitting for 14 hours in 20 degree and below temps. Does anyone have any ideas for a manual choke? I'm going to try to make one I can use once the body panels are back on (don't worry, I still have the fan shroud and the head shroud on it, I'd rather not overheat the engine).

They arent jetted for this sort of weather, wait till spring.

The whole reason for getting the Spree was so I could use it to avoid paying for parking while going to college (LCC, either you pay to park on their ramp, or you pay to park on the city streets). They let you pull any scooters right up to the bike rack. It'll save me over $100 a month. So, I kind of need it to run in this weather, as school starts ext semester for me. It has a 65 main jet, perhaps I could upjet to a 68 and richen the idle-air screw a little? They even have a recommended spark plug for cold climates in the service manual I could try. Would this help? Also, once the bike is broken in, I won't be running nearly as much oil:fuel ratio, so it won't be running as lean.

Also, another question: If these bikes aren't jetted for this temp (which I know they're not), I'm guessing they were never meant to be run here in Michigan......our temperature swings sometimes as much as 40 degrees in one day. So, how would one compensate for this, riding when it's below freezing in the morning, and 50 degrees in the afternoon?

You can install one of these.

* no, call them and they will come up with a kit for you. They did it for one of my quads.

You can't mean that everybody who rides a scooter in winter has one of these, I see people at MSU riding Sprees right now, I doubt they did anything to them (most college kids I know don't even know the difference between 2 and 4 stroke).

Obviously, the product would help, but those of us that are cost-conscious, wouldn't simply rejetting a little richer work in the winter? I know a fair amount of members on this forum are from Michigan, and I don't think that they ALL stop riding in the winter.....unless I'm just crazy...I do enjoy a cool breeze.

I imagine Washington has about the same weather we do, do you stop riding?

Yea 68 main turn in airscrew half a turn, adjust the midrange needle a click richer. You should be good.

Ok, sorry to bother you guys yet again, but, does anyone know of a parts source for a 68 jet? Because I can get one from my Honda dealership, but, it's just shy of $11. Ouch....for a piece of brass. Thank you guys for your help and advice, as always. Seriously.

dgsoles · Post by **dgsoles** » Fri Dec 05, 2008 8:04 pm

Oh, and a click richer means one click up, right? Mine's an '86, so it only has 3 positions, and middle is stock.

move clip one slot down, raising the needle

Thank you, that could've been one costly mistake....

hmm that dial a jet does seem promising for race applications...

$75 for single cyl kit

I have them on both my quads. The are for adjustments for temperature and altitude changes.
