Honda Spree and Elite 50 Forums

Whats up guys. Pretty exciting day for me so far just got the call that my parts for my scooter build are in. I ordered a 85 main, oem gaskets, .25mm over sized piston & rings, new circlips and finally a new small end bearing. Im pretty stoked to send the cyclinder to get it bored out. Also got a uni air filter. Cant wait to get started. Any advice on anything i should know would be great

Ah-Ha-Ha, I keed, I Keeed you! (Seriously, cut back on the caffeine-fueled exclamations...)

1. One common Rookie Mistake is not paying attention to the little circlips that keep the wrist pin from wandering. Check that they are completely seated in the little grooves all around. Then check again. Do it a third time. The ends of the "legs" shouldn't be in the gap where you insert your long-nose pliers, either. Avoid crushing them, or twisting so hard that you overcome the steel's natural elasticity. This results in a clip that's sort of "loose" and will fly out at the slightest provocation. This will cause an amazing Mess in your shiny new cylinder and piston. Use Just Enough force - or "Pull" actually -to coax them into place, dragging the Trailing leg of the clip in a twirl around the little circle until they pop into the groove. It's hard to describe, so if you're not sure how to handle that, get with someone who's got experience installing these and follow that advice.

2. Gasket Surfaces: Must be pristeen. Not a speck of anything to ruin the seal. One of the least fun parts of changing a top-end, particularly around the cylinder studs, but critically important. Ditto for the carb-to-manifold and manifolf-to-crankcase sealing surfaces. Even the exhaust has to fit and not leak - At All - for things to work right.

Wait so how big is 0.25mm oversized piston? Sorry i dont know how big the stock one is.
Is it a bbk or just the piston?

And like wheelman said, make sure the wrist pin clips are in there. Witnessed one that was not placed in good, fell out, scrapped cylinder walls, and messed things up real bad. Along wih the carb to mani, mani to block seal. Another one you should worry about is base gasket leak and head leak. Ran into bad gaskets with those too. Not a fun walk back home lol keep us posted with pics!!!

Are you working on that thing in Manchester? I can't wait to line up against you and see what you gained.

awesome! thanks for sharing! keep us posted on any updates on your project!

sorry guys been busy working but im sending out the cyclinder this week for the boring then im gunna give it some nice cross hatches. pics will be up soon along with some before and after speeds. does anyone know where i can find an exhaust for the af05e its like looking for a needle in a haystack! only gasket i couldnt get from honda was the gasket that sits ontop of the reed cage under the intake manifold so trip to autozone for some gasket paper will do the trick.

*I havent measured the piston yet but I will once i get home ill post the specs on it

just finished her up yesterday parts include keli vari with 9g rollers, 1k torgue spring, 1k clutch springs, new oem clutch, new oem reeds, .25 over piston/rings. Before shed go over 40mph now stuck at 40mph. Should i put in heavier rollers to gain a higher top speed?

Do you have stock or aftermarket gears.. Id say lighter on the weights

stock se50 gearing. Wont lighter weights give me more acceleration but less top speed?

Greetings:

You changed the Contra spring to a +1000 unit. The belt isn't getting into Overdrive because the spring is now too strong for the current weights.

For the variator to reach Overdrive, you may need to increase the weights by a few grams (3-6 total) to regain the top speed. As it is, the spring keeps it from happening when your engine arrives at its best RPM. If you had a more open pipe and/or carb and/or porting, you might get the top speed from increased RPM (which would increase the centrifugal force of the current weights against the spring...) but your engine won't get there in its current state of tune, so go heavier.

Wel if you had differnt gearing id go lighter.. Stock gears you should change those man..you'd be happy with it

Will do thanks a bunch man!

put the stock honda weights back in (there 10g) still doesnt seem like a difference. How heavy should i go or what would be good for me? I weigh 210 btw

Your not going to get much more up top with the stock gearing.. Swap your gears and youd say man i shoulda been done that

i want to but i cant find them anywhere
