I was looking to swap the motor in a sl150-27 to a 250cc. Does anyone have any comments or advice in doing so? Will it work? and what motor to use as replacement?

The 250s are liquid cooled and need a radiator and water pump

Do you think that could be added to the spider or do you know of a better option other than a 250cc?

the water pump is on the engine, so thats taken care of, a mini radiator from a liquid cooled 150 honda or other quality brand and a good electric fan should cool it. damn uninformed relies.
i was thinking of doing this swap in a different scooter, that already had 13 inch wheels as i have a low mileage linhai 260. and a big wheel 13 inch retro scooter. just about everything measured up where it would fit with very little effort, they only problem? the engine doesnt fit inside the body, its to long in the front, i would have to cut the body because the valve cover sticks out to far. my only idea to solve this, was switch over to the 244 and remove the bucket. would be a great scooter, with no storage space instead of just a little bit, but still might be super awesome.
my idea was a powerful retro that wasnt a 6000 dollar vespa. I really need to find a 244 scooter to measure, but all the 250s in Ce and mine fleet are kymco and linhai. I dont need the storage space i need a scooter to run me back and forth across town 3 or 4 times a day for class.
you on the other hand with the spider have the room to fit it. you have tons of room, only problem, the 250 spiders only do 55 mph because of all the extra weight they have to push around with 19ish hp. if i could get a spider trike really cheap, i would try and fit a 500cc or so sport bike engine, just to be able to do say 70ish easily.

or if your welding is good, cut the gy6 rear section out and swap in a 400 hondamatic frame section with engine and everything. the 400 is 27 hp, the cb750 automatic is 47hp,
they are called hondamatic, but really arent, they are 2 speed clutchless, so all you would need to rig is a lever to switch from high to low.
also there are insurance auctions that sell totaled out scooters, find a 400 burgman, 650, or 600 silverwing thats front end wrecked and weld that rear section in place of the gy6 rear section.
all much better options than a $2300 232 with 17 hp.

Thank you everyone for your advice. My main goal is to make the scooter do 50mph. It sounds like I can do that with a 250cc and not much mods so that is probably what I will do. Can anyone say why a 232 is twice the cost of a 250? Secondly I take it from comments the rear of this spider is a gy6?

One more thing does anyone know of a side x side spider with a 250 that doesn't cost $5500?

Can anyone offer other options to reach my goal of 50mph? And if I do try do do an engine swap what other problems may I run into such as parts that won't fit right?

A gy6 150cc bike should already hit 50 with no problems. It should already be able to hit 50 and should have a top speed of almost 65.
I suggest researching gy6 systems. I can't tell you why your bike won't go 50 since you didn't tell us any problems or symptoms.
But if it was running correctly, 50 would be about 5000 rpm cruising speed.

the OP is not referring to a scooter, its a reverse trike with 2 seats and an steering wheel, and weighs 460 pounds without and driver or passenger. it just has a scooter rear end with motor and drive wheel.
worewren has the 250 viper and its top speed is 50 mph. but weighs 1048lbs dry.
so the lighter 150 trike with a 250 swapped in should be the way to go. it should be a relatively easy swap with few modded parts. get the 150 trike and get a low mileage 250 engine from someone parting a scooter out. and blam done presto.

Thank you for the advice I feel more confident in this decision and not like I'm a fool for think about doing this.

Chromes, Thank you for the offer but I actually don't have the scooter yet. It is something I intend on doing within a month or two. If you still have the engine then I would probably want it. How much do you want for it?

Lets put the engine swap idea on hold as later option .
Put HP on hold too.
Now lets find out exactly what you have and how it runs . How many miles on it ? Compression test ? How much do you weigh ? Check rollers for flat spots which limit their ability to roll and performance loss . Weigh them as you may need 2 or 3 grams lighter to keep the rpms up . Do you have a tach . What is top speed and rpm if you have a tach ? Hows the belt look ? It may be stretched and new replacing . What size carb and jet sizes ? Clean the air filter . Check for vacuum leaks . You might need a new fuel filter . A NGK iridium sparkplug will truly help any engine run at its best and start easier .
Now after that if you want more power a BBK is cheaper up to a 59mm and a few 60mm may work but any larger requires case boring . A larger piston can develop more HP and require a larger main jet . Unrestricted exhaust will help flow and require rejetting to avoid being too lean . Slider weights can push the belt out further and its like having more gear ratios , the last longer , do not rattle like rollers and you can go faster . I replaced 12 gram rollers ( 12.2 on a scale ) with 12gram DRP sliders . Takeoff was just a hair less than before but a more steady climb when accelerating and I gained 5 mph on top end . 11s woulds be better for an Echarm . A larger diameter variator like DRPs will have a higher top speed . You can change out the drive gears will taller ones but use lighter weights to help uphill and takeoff . Larger jet will help and a larger carb can too but too large is no good .
Any GY6 should be able to go 50 mph if its tuned and in good shape . So lets get you tuned if need to get a base to start from as there is so many mods to go faster later .
Find a scooter buddy with a 50 so you can always be faster than him , well if his is stock

Let me start by saying thank you for all and any help.
Next let me say that I may have been misleading as I do not have a scooter or a spider yet. To clarify I am waiting on a bonus check and then I think I want to get a SL150-27, if you look it up it is classified as a scooter but it is a revers trike with two seats side x side. I know someone that owns one and reading about them they go top speed of 35mph. I was thinking the only way I would by one is if I could drive it to work (it would be so cool), but the streets are 45 and 50mph and I don't want to get run down doing 35mph. I also understand that the spider goes 35mph around 8000rpm, that sound like I will be running the dog piss out of that engine just to go 35.
So my main goal is to get a top speed of 50-55 and that would help lower the rpms when cruising at 35. Any suggestions on how to do that is greatly appreciated, my only thought was "engine swap".
Lastly let me say that most of what you said Skutta went right over my head, I think mostly because I don't have a scooter yet and have not torn into one. I am not a dumb person and I am very mechanically inclined but I have never worked on this type of animal before. Please understand. Thank you.

The link you posted is for a can-am (which I can't afford). The trike I'm looking at is at this site www.tjpowermax.com/the-spider-150cc-3-wheel-2-seater-moped-scooter--street-15033.htmlMy budget for this would be about $4,000, and I have to have this body style. The Viper is similar with a 250 in it but the cost is $5,500. I feel that I could buy the 150 and do engine swap within my budget. but if anyone knows of one these with a 250 for around 4k let me know!
