ac to lc conversion

[jmkjr72]

i have a lead on some lc parts for my zuma(water pump radiator thermostat hoses and overflow)
has any one tried this and have any advice
i am also looking at a use bbk from the same seller
polini conetessa 70cc cast iron lc kit has any one tried this kit i know the name is good but i wonder if 100 bucks for a kit with 600 miles on it is worth it

[jmkjr72]

well im getting the parts i paid for the lc parts and will give pay for the bbk next week as im waiting on a check right now from the ins company from when my scooter was vandelized should have been here today but no such luck i hope its here monday

but i have a copy of the yamaha aerox (lc horizontal min engine) service manual so the conversion should be pretty straight forward

i will have to mount the radiator in a diffrent spot thanks to the diffrent body style i will be going behind the tire and will put a screen over the radiator to prevent any stones from hitting it and depending upon what overflow tank the guy was using will dictate where i mount that the decision will be if i cut a hole in the body work so i can see if the overflow is low or not

now i just have to make sure i have enough al flat stock laying around to make mounting brackets for all the new stuff and that means a trip to fleet farm

When you posted this thread was thinking that I have not seen any posts regarding this project posted by any of our members here or on the other forums either. So you will get to be the first of the group to fill us in on how it goes. Good luck to you.

I was looking into it for my other Triton, but I've never got around to building that thing yet so I don't really have any useful info.

[jmkjr72]

Good, thanks for sharing.

ok so my cool new to me parts are on the way
due to a tight budget i went with used parts

i am getting this slick vented trans cover


and this is the bbk

Cylinder Polini 70cc Sport
Polini, the
Polini, the market leader in two stroke tuning, have produced this reliable cast-iron kit for everyday use. Will work with the original carburettor although mainjet should be increased by aprox. 8-10%, power output up to 9 Bhp. Remarkable because of its massive bottom end punch, which makes it a wheely addict's premier choice


and hopefully all the goodies i need (hoses water pump radiator and so on)

so it will be time to get fast again :>

Yep thats straight off scoot-attack description ;D. I have the same kit in AC version, its sweet, tons of low end. Hope you ride wheelies, or are at least ready to learn how ;D. You will be very happy with this kit and a good tune with the right pipe. What pipe are you using?
That is a wicked CVT cooling set up, what is it, were, how much?

[90GTVert]

Nice setup. Can't wait to see how it turns out for you. I wanna mess with a Polini Sport kit to see just what it's like, but I have nothing to put it on at the moment. Hopefully I'm gonna install one for someone else in the near future though.

i got it used you can get it from scooter attack or you ight want to try spmotors out of canada it is made by top performance

as for pipe right now i have the leo vince sp3 i know it will hold the kit back some but hell when i had the top preformance trophy kit i was able to hit 60 with that kit and the sp3

heck with a stock bore and this pipe i can hit 50 so i dont think it will hold me back too much

i may upgrade to the leo vince gp pipe and paint it blace if i do i like the "sleeper" look to my scoot it doesnt look like it goes and then all hell brakes loose when i get on the throttle

[2strokd]

Cool, cant wait for your posts of the results, Polini makes good stuff. Tell me more about that CVT cover? I have never seen one like that

[jmkjr72]

i realy dont know much about the trans cover ill take some more pics when i have it in hand(ok well next saturday as i will be at scout camp all week long)

i belive it is an after market version of the bws 100 trans cover the guy i got it from had it on his race zuma so im sure its lighter and when painted to match the scoot will look realy sharp plus i dont have to drill holes or cut up a stock cover

[2strokd]

Right, cool i look forward to the rest of your build.

[jmkjr72]

ok well i will get to this build in a week or two now that i have another scooter to ride one reason i cant tare into this right away is my zuma is still at my office in greenbay and will bet stored there for a few days till i can get ride to the shop to ride it home then the build will be done one peice at a time when i have free moments

[jmkjr72]

well thanks to the wreck the build was put off for a bit but the parts list is coming together
i now have a 19mm arreche carb to add to the build and now that the cold weather has set in as i get time on the weekends i will be tearing into the zuma
on my list to get still is an expansion pipe and a throttle cable heck i may even swap out to a short throw throttle assembly and an open filter to put on the carb and a new set of cf reeds
