Bw'S ( Zuma) 100cc and Jog MVT SC90

[kevin55950]

I need your opinion!
I ordered a ''brake light'' ( officially an Aerox custom headlight) I can directly mold with the rear end. I'll make a 2 or 3 part mold to get a 1-piece rear end.
But should I make a rounder underpanel (no plate holder) or it is a better idea to make a plate holder where the gas tank is in the way for a flat panel?
I've already done a lot of finishing work ( I found using gyproc plaster is the best way to make a mold as it sands and dries fast) and now I need to do the under part of the rear fairings.

The headlight is 2-bulb type ( like the Greenwood rear fairing) and I want to get a switch that shut down one of the light (by the negative wire) when the current from flasher comes, like some cars and Ducati motorcycles. I'll check with my local police if it's legal or not. If illegal, I'll mold separate flashers.

I'm seriously going towards the MVT90 SC engine but I'll maybe look for a custom-made exhaust... The ones made for the MVT engine are too noisy to even go on the street and there is noise regulation at my local drag strip so... I don't want a scooter that is kept in the garage without moving. Is 190Mech making custom ones ? I'm interested...

I'm also looking for an Aerox engine case because of the rear disk brake and because I can install a mechanical water pump without problems.

I'll keep the headlight I used for my base mold for the front panel but I'll only keep the lens: I'm looking to install 2 Halo projector headlamps and flashers behind the lens. The rear part of the Aerox headlight is too thick to fit with a single bulb in the middle and I don't want to trash it, also it will be a big deal to make solid brakets for the rear fairings (brackets from the frame to the headlight) and making brackets directly in the fiberglass will require a lot of adjustments.

Flat panel seems like a good way to turn the fuel tank hump into something useful. Rounded undertail would be the smoothest, but then you have to have a tag hanging off somewhere else. I think either would look good.

You'll need to PM 190mech to know what he'll do for sure.

Little preview of the new brakelight..



Still a lot of work to do !

[teddy554]

looks like you have a lot of sanding to do

[kevin55950]

Yes! But it's not that bad with gyproc plaster. The light is held there with body filler which is way harder to sand, but I use plaster as max as I can, that makes the sanding and shaping process way faster. I should have used this since the beginning ..

Recent changes... all in the title ! I'll post pictures as soon as I receive the engine. I will not have all the parts needed at once so it will take some time till you can hear it run.

Race engine, sounds good

[kevin55950]

Yes! I mean, last summer this build was for the street, my daily driven scooter. But I have my car now and there is some race event organised. Registering a scooter now costs $270+ in here, plus insurance so I don't know if I'll use it on the road again... That's why the ''race engine'' :lol:

The 103cc engine build was fun to do, gave me a lot of experience, but already having the MVT crankshaft, an engine case that matches the spec to fit the the MVT 90 cylinder, some other parts I can reuse and more budget makes this build possible to me.

The experience I gained building the 103cc got me used to spacing cylinder, fabing or adapting some parts, jetting carburetor, avoiding problems etc. thus I'll have less chance to break the MVT cylinder kit (+2 times the price of a 54mm bore cylinder).

I always wanted to build an high-end engine someday.
I want to use it for lapping and drag racing ( my goal is not to absolutely be in the first place, just to have a lot of fun )
I want to put a performance ignition like malossi, mvt or else, get a good exhaust for this engine, complete over range transmission, etc.

And finally, if I have the money to register it, I'll look for a quieter silencer and kart airbox ( if it don't lower the performances too much). Just to take a ride on the street from time to time. There are some nice curvy roads near my house .

I'm looking at this and...
I have a Jog which is lighter than the Zuma. I have spare zuma forks and wheels, and I can't register the jog without an inspection. Some fairings are worn, front forks are dead (not dangerous but can't pass inspection) and engine mount state is somewhat questionable... has been weld so much times lol). It might be better for the race build... And I will be able to keep the 100cc zuma on the street. I can install zuma fork, case (of the MVT 90) and wheels on the Jog. I have a spare case which needs some work but it's already machined for the 100cc.
Do you think it's a good idea ?

In your opinion, which one will you use for the race build?

Laws are getting more and more severe on noise regulations and scooter tuning in general that it makes me afraid to put the MVT build on the street (I followed my friends on scooters with my car today and it made me sad because I wasn't able to have fun with them )

Looks too hard for me to have no scooter which I can ride safely on the street...

[aeroxbud]

It should be cheap running a scooter on the road, but sometimes it just sucks!
Just got my scooter insurance quote today £156 for a year! What sucks even more that is with 65 persent no claims discount

[kevin55950]

$273 this year to register a scooter... and the first year I registered a scooter it was around $50... Price climbs FAST! Insurance is $150-200 easily, no claims also.

If I put the zuma back on the street, it's with an athena crankshaft or 41,4mm crankshaft with a better exhaust ( IDK if I can find the same but for Bw'S 100, mine was for a 70cc for sure, wasn't performing well on the 103cc but it was awesome on a sport 70cc setup.)

I'm waiting the MVT cyl. kit, little delays in delivery, and if I take the jog, I will not need an ignition with headlight power output. Costs way less!

Finally received this
More pictures will come later.

Beautiful high end toy I like it

Sent from my PG86100 using proboards

[kevin55950]

And some people told me it's far from a Fa2st and a malossi BB86 blah blah... We'll see how it performs for less than half the price of a BB86!
