new spree owner, wants a bit more...

neverlift · Post by **neverlift** » Fri Dec 14, 2007 3:24 pm

Ok guys, I recently became owner of an 87 spree(I think details have not been clear IMHO), I'm wondering what aftermarket support I have for the nq50 engine in the scooter. I found the vtcycles place but they do not list anything performance wise for the scooter. SO are any other models upgrade parts compatible? Also would the sb manifold/reeds be worht the cost,a good place to find them?

Scooter tops out around 27~28 on the flats... I figure thats good for a stock bike, the filter is gone tho, any thoughts to replace this cheap?
thanks in advance!

DO NOT RUN WITHOUT THE FILTER! YOUR ENGINE COULD LEAN OUT AND BURN UP! You can buy a new filter for less than $5 pretty much anywhere Honda motorcycles are sold. There are no bolt on upgrades because the trans is not tune able. Some common mods are drill 3-4 baffles out of the exhaust pipe and grinding out the lip in the intake manifold.

its not leaning out but its just on the edge, I had the lid off the cleaner and it was lean all the way

I need a jet,filter and battery. Already poked thru 2 baffles

lip in the manifold??? is that the point of an sb intake swap, like I saw posted on here?

You plug chopped it correct? Because just cause it isnt bogging doesn't mean it wont have a shorter life (sound insnt everything, you cant tune these carbs by ear), and even if it isnt bogging there is s*** in the air that tends to do bad things in a metal on metal situation (hence why it has an air filter in the first place). Why do you need a new jet? The SB manifold has bigger reeds and a larger bore but you get a similar performance increase without modding the petcock for the price of an hour with a dremel and some metal polish. If you remove the intake you will see what im talking about.

not much possible for the stock fixed ratio trans/engine setup, ppl have ported intake manifold and done pulley mod but you wont gain more than maybe 2-3mph.

If you want 50+mph easy, look into doing a dio swap..

well I'd love 50+ on a scooter, the wife not so much 28 is more than enough for her....
kenny I didnt go all out and cut my plug, but everything is fine trust me, I've been tuning for some time now(granted its been on 4cylinder nissans engines(currently drive a 90 240sx with a swapped out ka24de(dual cam) that I installed a budget turbo setup and tuned with a single cam ecu.... not relate too much here but pointing out I understand a/fr's and how to read a plug.
need a bigger jet cause the motor leans out when I remove the lid... like I posted in the first one

this pully mod , can you link me to something on it?

"Honda Spree/SB50 Pulley Mod How-To"
i found this in the 'Advanced Tech Docs' part of the site. That part of the site is extremely helpful if your looking to speed up any moped.

I know there is one guy on here 'MySpree' that did the pulley mod and ported just about everything. Along with allot of fine tuning he clams speeds of 40-45mph. For a Spree motor thats amazing.
Sprees are hard to tune up. there really isnt allot there. Dio motors ( 94-01 Honda Elites 50's) have tons of aftermarket parts. if it can be taken off the motor you can buy it aftermarket. But a Spree is all about tuning.

Also, Kenny_McCormic is 100% right. No matter how much you work on bigger motors. these little 2 strokes are way different. and as much as i hate to say it the only real way to see if your running lean (besides lack of smoke) is to plug chop.
I cant tell you how many times i have not done a plug chop after modding (even drilling the baffles) and ended up with a fried Cylinder/piston/rings. Plug Chops take 5 minutes and cost a new spark plug, but unlike big motors it can really save your * in advance.

Advanced Tech Docs part of this site has a few articles on Spree Modding. you might want to check it out when you get a second.

And it looks you are a little confused on what a plug chop really is. let me explain.

~What you do is you get a brand new spark plug And put it in.
~Start your motor up ( if it needs to warm up you can let it warm up).
~Take it for a ride, full throttle for a mile or so.
~Kill the motor at full throttle. cost to the side of the road
~remove plug and see the color.

this is about perfect. Any darker means your running rich, any lighter means your running lean and its time to get a different jet.

Side notes
- a cleaned up spark plug works also, as long as the white part is still white
-if your smart you can do it on your way home and just cost into your driveway.
-Dont let the motor idle, it will change the color. you have to kill it at full speed.
-Letting the motor cool down wont change the color. so you dont have to burn yourself trying to get it out.

That is how to do a plug chop. I hope this helps you.

Even a used plug will work, it just takes longer to read perfectly. and you dont need a bigger jet, the lid is there for a reason, leave it there. As said before these things are really picky and will burn up before you can say AW f***!.

Well Ive done 5 plug chops if thats what you guys call it. They all look just like yours do....
would you coinsider * more then 3 hours driving?
thanks for the link, I must have missed it, I've been on this site for a couple days now(reading not posting). I mean I didnt even ask how to get this old pos running.

Dac and Kenny made good points here. I ran my Spree without a filter on the stock piston and rings that had 7,800 miles on them, I got around the block twice and fried my rings. I was running way too lean. Turns out I had some old Shop Vac hose and a foam filter from a push mower that fit and worked perfectly, had a nice cocoa brown color like in that pic after I replaced the piston and rings. I got lucky on that. So plug chop often, it's a good practice.

But since I parted out my bike because the main bearings were going, it kept blowing pistons cuz of it. Got sick of rebuilding it.

The spree is a joke if you want speed and most of you can't afford to build real speed
