Engine Swap Parts List: 1984 NQ50 to 1987 SE50P

Post by Ry_Bibs »

This is what I used swap a SE50P engine into a Spree For the records, I had a 1984 Spree and swapped in a 1987 Honda Elite 50 SE50P engine. Feel free to add anything, but this is what it took for me (a poor college student in a student apartment) to swap engines with minimal tools and money. IÔÇÖm purely making this list to save others the pain of having to browse millions of separate posts to find this one list.

You will need (or at least my parts list):

1) Honda Spree (duh)
2) Honda Elite SE50P throttle cable
3) Honda Elite SE50P brake cable (the original brake cable on my Spree doesn't reach)
4) Honda Elite SE50P Engine with matching carburetor (I had to buy and fabricate a starter motor for mine, as they harvested certain parts from my engine. Lucky for me, this engine also has a kick start! EBay and this forum can be your best friends for these items, as well as I went through partzilla.com to order my other odd and end bolts and nuts)
5) Honda Elite SE50P exhaust
6) Honda Elite SE50P engine mount (eBay find)
7) Honda Elite SE50P Rear rim (tire from Spree is the same size, the drum itself is a different diameter)
8) I did an aftermarket air filter and taped it up as noted on another forum post (covering about 90-95% of filter)
9) 8,9,10,12,14,22mm wrenches and sockets at best (I bought a cheap-o tool set from Walmart for $20ish)
10) 10-140mm bolt (I used a 10-120mm and was fine Just make sure to space with washers), but and I grabbed fourteen (14) 10mm washers for the new shock mount (play it safe and save myself a trip back to the store)
11) A 25/64 drill bit (the conversion comes out to 9.9mm Wiggle it around a bit and youre good to go!)
12) Hack Saw (Could go Dremel, but again, this is the poor college student budget)
13) Wire cutters
14) Needle nose pliers
15) Phillips and flat screwdriver (again, that Walmart tool kit saved me a ton here)
16) Crescent wrench (used it to bend the support guards out when my saw couldnÔÇÖt make it into the frame further)
17) New hosing for vacuum pump (that old red tubing from 1984 wasnÔÇÖt cutting it anymore)

I will attempt to resize my iPhone photos so you all can see my Spree.

As for a kickstand, I am still having mine do the ÔÇÿwall leanÔÇÖÔǪ Only because he is that cool for school. But really, if anyone has suggestions for how to CHEAPLY add a kickstand, I would forever be grateful!

Keep on SpreeÔÇÖing on, as this fourm has been a major help to me! Hence why I have taken the time between summer school classes to write this up for anyone looking to dive right in to an engine swap as I did. I owned the Spree two weeks before I swapped out the engine. I am still waiting for my final shipment of parts to come in, and will post back when I get her up and running!

Thanks! I ordered the "Universal Clamp On Chrome Emgo Tapered Air Filter Mini Bike Pit Bike 28mm" from Ebay. Guy shipped it super quick and it's a perfect fit. $10.99 was all that I paid, as he offers free shipping.

Thanks for posting that info up, just ordered one myself!

The foam uni filter I have is proving difficult to block off adequately, hopefully this ends up being the last piece I need to get everything dialed in correctly.

No problem at all! I have yet to get it all started up, but so far it's been all 'plug and play'. I changed out the stator and the electric start with the one that was original to the Spree's NQ50 engine. Saved me the time cutting and putting on new bullet connectors on the new SE50P engine. We shall see if it proves itself in the coming days!

I got lucky there, the motor I used ('85 Aero) had the same connectors right off the bat.

Sounds like you're well on the way, but heres the build thread for my swap if you're interested:

So hoping this pays off... Looks a lot meaner than the old NQ50 for sure!

Oh man, that was fun! Just took this bad boy up and down the street... Hit 35mph no problem! Now, I pose this slew of issues:

The bikes starts fine (via kick start), but the electric motor chooses when it wants to and not want to engage. Battery issue possibly?

The bike runs fine, but it won't idle. Is this a carb adjustment, cable adjustment... etc?

Thanks ahead of schedule for any help!

You should be able to fix your idling situation by adjusting the carb screws, just make sure to get it warmed up first so the bystarter isn't open when you set everything.

Also might want to trim that mud flap in the back LOL!

Haha, yeah I hacked off a good amount from the rear fender... It's 'cafe clearance' as I'd like to call it! Good thing I only weigh 140lbs haha!

As for the carb screws, I've done the 1 7/8th's of a turn trick, then run the idle all the way in, all the way out and everything in-between. No luck...
