well i should have my crank here soon as well as the adjustable oil pump so all i need now is a nice agressive 54mm liquid cooled bore i ended up with a 43mm crank instead of a 44 or 45 like i wanted but the price was right and it is an athena crank that should be good for more revs then i will ever...

jmkjr72

2 strokes can rev a lot higher then 4 strokes so they are faster

4 strokes do tend to make a bit more torque then the 2 stroke so if you cant hold the revs on a hill a 4 stroke may catch up a bit there

jmkjr72

i have 15000 on my yamaha zuma well thats on the crank as i have moded it and changed things a couple of times but there are several zumas over on zf that have had over 20000 miles and one had over 30000 before he reubuilt the top end and those rebuilds were still running when they did them so proab...

jmkjr72

but that 150 will still be slower then a good zuma

jmkjr72

with a zx and the right rollers and tmod you chould be hitting 40 to 45 with an 09 what rollers are you running allt he 4.3 that came with the zx or are you running a mix of 1/2 leo and 1/2 oem (this should be about 5.5 grams) also have you had the recall done or not if so dont do it as they lean th...

if you are still running an oem non squish band head (the hump head you need the bp7hs to get the spark down where it needs to be other wise you dont get proper combustion but if you have an aftermarket bore kit or just an after market squish band head (this will bump compresion up and increase your...

jmkjr72

why not look localy there are tons of them at places like fleet farm menards home depot walmart and even your local parts store
that have an exterior sensor
and they can be had for right around 5 bucks

jmkjr72

I like the project but you won't get much benefit in economy versus a properly set up carburetor. Fun to do though. As for turbo again fun but I doubt it will work. The turbo blows mixture into the crankcase but the scavenging is still controlled by the ports. Not to mention the increased pressure ...

jmkjr72

So, you generally have it sorted out... other than the fuel pump current draw problem? It would be interesting to hear about how the install went, how you debugged it, and any performance gains. I've been wondering how well of these FI kits would work on a kitted Stella 4T. Good thread. well i had ...

jmkjr72

well just an update as i ahvent been over here in a while i put close to 5000 miles on the scoot with the efi set up on it the down side is the fuel pump draws so much that if you are a low rpm short hopper it will draw your battery down but there are big changes in for the zuma over the winter i wi...

jmkjr72

a belt should last lots longer then that i have 15000 miles on my zuma and its modded out and im only on my second belt

something just doesnt seem right

check to make sure your belt is running true and that there is no damage to the rear sheaves that has caused the excessive wear

jmkjr72

i have gon dozens of times takeing the clubs up to 50 miles one way with them laying in the rack sidways as long as tou strap it down good they dont go any where i normaly wrap a bunji just below the head and pull it back towards the bag i have done it on both the stella and the zuma i will say it w...

jmkjr72

well i call the stella olive
as she is an olive green but may not stay green forever thanks to the 2 wrecks she has a lot of primer gray on her now

and the zuma 50
i call her lc(elsi)
as she is liquid cooled and fuel injected

jmkjr72

there used to be several companies makeing dog crates for the back of scooter and motorcycles but they have all gone under they just couldnt get them aforadable enough as they were pretty much heavy crates that could take a wreck and still be intact as for if this one bolts on to a rack or not i hav...

jmkjr72

yeah pull the lines and pull a vacuum on the vacuum line
personaly i use a vacuum brake bleeder set up to drain tanks bone dry

jmkjr72

i have progressive for the cars scoots and motorcycle

one think that helps big time with progressive is they give you credit for years of riding not just years of having a motorcycle endoresment

where gico and others asked how long i had my endorsemnt progressive asked how long have i been riding

jmkjr72

warranty whats a warranty as my zuma sits with out a gear ratio chagne it runs 55 all day long and hits 60 but i am also limiting the revs to 10,000 rpm becase i have 15,000 miles on the oem crank and bearings as she sits i am running a lc polini corsa lit leo zx pipe stage 6 varatior and drive face...

jmkjr72

the magnets will only work on some inductive loops and many intersection that are trafic controled are going away from the inductive loops for an ir type sensor that is above ground why are they doing this well the systems are easier to maintain and if they go haywire you dont have to bust up the ro...

My neighbor's Yamaha was stolen a couple of days ago in Cambridge from in front of our building. He was just running in for a half-hour and didn't think to lock it up or even lock the steering column. Someone just walked into our courtyard in broad daylight and roll it away through a park with tons...

jmkjr72

we have the law in wi its only 30 seconds for us the one word of advice i have is if you see a car pull up behind you and your not sure its a cop start your count over or if you see a cop cross wait a bit before you run as he has no idea how long you have been there aand it was a cop that sugested t...

a back fire on a 2 stroke means only one thing unburnt fuel is getting into the pipe some unburnt fuel is nromal and shouldnd cause a back fire reed valves that are not sealing is one way unburnt fuel would get in poor spark is another with that few km i doubt it would be low compresion did they run...

jmkjr72

and if you have short legs you might not like the zuma the seat is high compared to the buddy

jmkjr72

a small cvt scoot will not handel a side car

if you have a small dog there are some rear carrieres for dogs out there but the good ones are expensive

jmkjr72

the zuma 125 is not liquid cooled it doesnt even have an oil cooler

if you realy want to know about the zuma 125 head over to zumaforums.net

i dont know if shawn is over here but he got sold his moded zuma 125 and got a blur 220

towing involves all aspect of the tow vehcile cooling (the eng and trans are working harder and you need more cooling the larger the load) brakeing (you need more brake power when towing) suspension(you will work the suspension harder and if your rear suspension is not heavy enough you will take wie...

jmkjr72

the one thing i didnt see you mention is what the towing capicity of the car its self is you mention the hitch thats what the hitch is able to deal with but you didnt say anything about what the car is able to deal with i can slap a bigger hitch on my truck but that doesnt mean i can tow more if my ...

jmkjr72

the limiting factor on being able to hook up to a trailer with a class 1 or 2 hitch is the balls you can only tow things with 1 7/8 or 2 in balls then the other thing that you need to worry about is getting the proper lift for your draw bar(being you have a small car you will need lift and not a dro...

jmkjr72

http://www.youtube.com/watch?v=JDUrt38coLM no i had to get a diffrent intake as the throttle body was too large for the oem intake i am still waiting on my airfilter to get here and i have to pretty up the the hoses and also get my second injector bung and get that mounted up too and i have to plug ...

jmkjr72

we will have a group ride june 18th
meet up at riverside rides in depere
we will leave at 3pm as always

jmkjr72

i have filled it to the point when it sits in the sun i get fuel to come out of the vent and never had an issue

jmkjr72

i call my stella olive
and my zuma lc or lcz

jmkjr72

my box of super sexy fi parts got here today
it seems to be missing the bung for the second injector but its no big deal right now im still waiting for my new intake and air filter

jmkjr72

if you dont know what the po used
i would run it as low as you dare and then refill with the oil of your choice

personaly i run nothing but 2 stroke sytnh oil on both of my 2 strokes
the only thing on my stella that doesnt use full synth is the trans as that is sae 30 non detergant oil

jmkjr72

No vehicle with electronic ignition will run properly with a marginal battery, even if it does fire. One of our motorcycles evens cuts out with turning on the signal lights when the battery stressed. Anyways, having a high output alternator could greatly extend the riding season around here......he...

jmkjr72

yeah its simular as that compnay doesnt do it for the 2 strokes this kit comes with 2 injectors a switch so you can go between eco and rich mode (this would be handy if you have e85 in your area fill up with regular run in eco fill up on e85 run on rich) there 4 stroke kit comes with a new cdi that ...

jmkjr72

yes its a closed loop kit
its put togehter by ecotran

jmkjr72

ummm yeah 25 miles to work at the shortest route
and i have to be home early to prep for a boy scout camping trip i dont think so it wont even be a scoot to work day

jmkjr72

i wouldnt say die hard just dont know when to leave well enough alone

and besides whats better then a little "50" cc womping on the big bikes or takeing off thru traffic

if all goes well with this fi set up it could lead to a boosted 2 stroke race scoot down the road

jmkjr72

well some of you know i have converted my zuma from air cooled to liquid cooled now comes the next phase gettting rid of the carb and going efi so in the end i will have a liquid cooled fuel injected 2 stroke scooter hopefully i will gain a few of the mpgs i lost thru the mods back as for performnac...

jmkjr72

if we are talking about a low oil light on a 2 stroke i will say like i say over on the zuma site

if you wait long engouh for the light to come on you waited too long
as one of these days that light is not going to work and you will run out of oil

jmkjr72

the sad thing is there are lots of idiots out there that will pay too much for those pos scoots and then get upset when they bring them to me to fix and find out how much its going to cost to get it to run right for a short period of time

jmkjr72

retail value is what you should expect to pay for a fully recondsioned unit at a dealership trade in is what you should expect a dealership to give you private party is noramly about in the middle of the 2 but the big factor os the local market right now here with 4 buck a gallon gas people are aski...

jmkjr72

more then likely it needs a new thermocouple on there
every couple of years when i go to relight the furnace and it wont light i replace that and away i go

jmkjr72

more then likely dealers starting rumors so they can charge a premium if they do get any or makeing an excuse to cover up there mistake and i havent heard anything about them being killed off on the zuma board and yamaha lists a 2011 on there website and you know more often then not on the boards we...

jmkjr72

yeah it isnto going to fit in the stock spot
put it under the cowel or see if there is room up in the fender

jmkjr72

yep and geunine is running low on 2 strokes too
my dealer called to see if they could get another avadaco and that color is gone unless you want to wait for a 4 stroke
and last i heard even scooterville in mn hasnt gotten any 4 strokes yet
