Recently I helped a my bother-n-law do a motor swap on a 86 spree and put a 87 or 88 elite 50cc motor on it and it bolted right up. The motor was sitting for about 15 years may be longer still in good shape. That was pretty cool that it did that so anyway. I wanted to find out how to get 10 mph more out of a stock elite motor it does 25-27 right now. Thanks

If it bolted right up its probably a SB50 motor which is almost the same as a spree and has no upgrades. I could be wrong on that though. Take off the belt cover/kickstart and look at the drive pulley. Is it fixed or variable?

We did that and everything looked the same. One question can you ram air threw the carb. I don't know just asking. Or change the jet maybe jet change I don't want to do anything like a gear swap. I did a plug chop it good there. Starts on first kick everytime or with electric start. We need new side panels. Well thanks if any can help. Do you know anyone that would have a 86 spree frame no motor. We need to clean ours it out it had green toxic stuff don't know what it was. We bought that spree for $100 not running and swaped motor. IF you know anyone one this site that would have something like that let me know thanks.

If it has a spree trans its an SB50 which is a spree motor with better intake and exhaust. I would strongly recommend you dont play with jets and filters as its an true PITA to tune, just leave the airbox alone. Decarbonize your exhaust, that might help top speed. After that you can try drilling 2-3 baffles from you pipe, this will help take off and might add a little bit to the top end. However it will be lounder but you want that to attract attention on the road so you dont become a pancake. A set of spree side panels NIB runs ~$200 from a discount parts dealer.

Can I do that think with the clutch and take that back plate off. Maybe it might get rpm's up a little bit and maybe get more top end.

u pretty much cant do anything with a spree engine or a elite E sb50 engine. look into gettin a sa50 or a se50 engine.

I got a spare frame if you need one. Just no paperwork. I'll even take it down to the car wash and clean it up all nice for you. haha a pic can be seen in the wanted/for sale section, I have a post in there on it.
