1pe52qmg its official

[ryan52]

so today i have recieved a whole slew of parts.

1pe52qmg engine (52mm bore)
malossi carbon fiber reeds
19mm carb with 90 main jet
set of roller weights 4-9 gram
2000 clutch springs
2000 torque spring
kevlar belt
unlimited rev cdi
iridium plug

im really excited to start the build, it will be going in my jonway wasp/hornet, in replace of my 70cc engine.
with my 70cc engine i could top out at 55-56, hoping to beat that with everything i got engine with all parts. etc. so carasdad look out when i come bye!! the build will start tomorrow because i do not have 2 stroke oil on hand

also i do have a stroker crank for the 90 and im ordering the 54mm bbk just thought id let everyone know on the site!!

[millsc]

[ryan52]

hope so but im really wanting this to be a good build. people look at me like im stupid when i talk about my builds. i mean im 19 but hey others have weirder hobbies.

[millsc]

The heck with 'em. If building Scoots makes you happy. It's your hobby.

[ryan52]

thanks for support. but yeah im gonna try and get this build going pretty soon tomorrow i think if i get my weights in!!

[skuttadawg]

Enjoy your hobby like most of us do . Here is some food reading with tips 49ccscoot.proboards.com/index.cgi?board=yamajog&action=display&thread=1274&page=1 and 49ccscoot.proboards.com/index.cgi?action=display&board=yamajog&thread=1712&page=4

19mm is small since the 70cc power kits use a 19mm maybe a 21 would work better

[ryan52]

thats what i was thinking but its hard to find 21 carb that has stock setup like oil inlet elctric choke etc.

Good luck with the project bro! Start a thread in the "Custom Builds" section!

I'll be following...

[skuttadawg]

This place has many high end goodies www.spmotostore.com/category_s/3026.htm a 21 or bigger carb would need a matching intake . The 52mm is larger than 40mm of a 49cc and will need the extra flow . Now too big of a carb and you loose vacuum .

Now if you save up the money going with EFI will be a great investment like this kit www.ecotrons.com/2_Stroke_Small_Engine_EFI_kit.html It has the option of having a secondary injector that you can program the ECU to kick in at a certain RPM like just before the powerband . I have EFI on my Echarm and its no contest that EFI is superior in every way like power and MPG

[ryan52]

well im gonna wait till all my parts come in i gotta work out some killswitch issues but as soon as i get all my parts in ill start documenting and ill put it together. also my intake came as a genuine yamaha 100 intake so its bigger than my stock 49 by far.

[skuttadawg]

To give you an idea a Suzuki RM80 comes with a 28mm carb

[ryan52]

yes they do...direct replacements....and OEM Mikuni not cheap Chinese copies that are mis marked or not marked. It is what skuttadawg and I use only. get them from power barn... www.power-barn.com/servlet/Categories?keyword=vm11%2F22

[teddy554]

there are different size got to get the large round mikuni i found out the hard way and ordered 20 buck worth of mikuni round jet, smaller thread then the large round mukuni which is what this carb will take. This are for sale 3 buck each if anyone wants them by the way 77.5 80 82.5 87.5

Ive been using JetsRUs.com but that power barn is cheaper by a dollar or more. How long does it take to get them in the mail? I love in the same state as jetrus so it only takes 1-2 days after I order but if power barn is near 2-4 days I may start using them. Thanks for the link carasdad!

I have a friend trying to set up that kit on his Jog clone right now, the wiring looks cheap and is frail to the touch. He should have it finished in a few days. He had to fabricate an intake for the TB.

You are welcome...and Mike from power barn gets them to me in about 2-3 days. I live in Michigan so time may be different for you. Funny to...they typically arrive before the tracking number shows up online.. When it does show up..it says 'delivered' and hell by then the jet is already in the scoot.. ;D

[ryan52]

yeah i bought some from powerbarn the other night large round mikunis
