Honda Spree and Elite 50 Forums

well my 66cc kit came in the mail yesterday...and it seems legit

the bore just looks to me like a stock bore that has been over bored w/ a larger piston and it uses the stock head w/ no cutting needed
got it installed in a hair over 40min, put the key in, flipped the switch, and looked down to see this


i thought "thats probably not good"...but off kicking i went anyway and it started right up
let it idle for about 20min (meanwhile adjusting the idle for the new 24% displacement increase) and shut her down for about 30min
did that twice last night but i had to work today and i have no other wheels so i was forced to drive it the 2.3 miles to work babying it the whole way
while the bike was parked at work i put her threw about 6-7 more heat cycles before noon (not that busy at work today)
took it out for lunch for a 2.7 mile ride to the tech school, sat for 15 min then took it to the nearest deli for a sandwich, a little over 3 miles
well the rings must have set while my sandwich was getting made cause on my .5mile trip back to work...man... thats all i can say

i figured i had a little room to hold the throttle WOT for a sec or 2 on a straight stretch but as i pulled out the deli parking lot onto a side street i blipped it to about 1/2 throttle and the d*** front wheel lifted off the ground! i almost dumped the d*** thing cause i wasent ready for that s***

as it sits right now the 66 kit pulls harder at 1/2 throttle than my slightly ported stock bore did at WOT...once the break in is over ill give a full report of top speeds

and heres some install pics for good measure

negative on the pics- cant see.

Hah - 6660 miles at installation day
Thanks for the pics, write up and wheelie warnings!
Hard to see but maybe you have a pod filter on the carb? Any other changes - jets, exhaust?

oh yea i guess i could leave that info too

as of right now its stock exhaust w/ a pod filter (UNI) jet drilled to around 97 in the stock carb and it seems to be running a little rich
and ruck vari and 9.8-1 gears

Greetings:

Nice job both on assembly and photo-documentation. For the record, what is the engine and in what frame?

Altogether boys and girls, can you say "Power-to-weight ratio?" An enviable project. Nice job!

well for an extra $10 i could have gone your route w/ the 75cc nik-a-sil bore...but ize dont gots none them fancy measurein thangs like youz gots

if i would have bought a vapor gauge first then i probably would have went the same route as you, as i could have followed behind you learning from you mistakes/findings

Regrets?
I've had a few.
But then again,
Too few to mention.

If you're sticking with the stock carb sans airbox (Open pod?), try a 105 for starters. With SA box and well-oiled filter it's closer to 88 methinks.

let us know when it blows cuz it will blow

so is this something that you know based on experience??? or is this just more random s*** talking you like to take part in??

Ya been there done that and i had the proper gear ratio meaning you don't want the front end to lift, the rings are cheap carbon and should be chrome molly, the cylinder should be ni-si treated.

Nicasil is for aluminum cylinders- It is used as a hard surface treatment so an iron sleeve does not have to be used. Iron cylinders have no need for nicasil coating.

Actually I take that back- looking into it further some manufacturers do use nikasil on iron bores for friction reduction- my bad.

my gear ratio is 9.8-1 right now...but if this kit seems to work ill probably be switching to 8.4-1

the kit looks to me as if they just bored out a stock cylinder and opened the exhaust port slightly (it still says 49cc on the casting)

idk...ill wait and see, if it blows it blows hopefully by then i got the $$ for a more top of the line kit
