what size carb?

what gearing?

sure a 64 is right?

You can get BIG kits for them (90cc). I'm going to be running an 80cc.

Port it. Also, there are much better pipes than a biturbo. Do you know if you had the 20 mph or 30 mph cylinder to start? You probably had the 20 so going 31 is actually an improvement of over 50%.

how old is your plug? You may just be getting not great spark limiting your speed. Or your jetted to high.

premium gas? really? thats your recommendation?

i use the good stuff every time, for sure, but its not adding any speed. shit.

I have a Mamba pipe with a 14.12 carb with no airbox and I'm running a 65 jet. I am in the low thirtys with mine. I have a 42 gear in the back and a 11 in the front. I was running a 10 tooth and it made a big dirrerence when I swapped to the 11.

definately port it some. Raise the exhause and lower the intake to reach some higher rpms and slap a 15 or 16 on it. Ditch the biturbo and get an estoril.

so how do you know if you have the 20 or 30 mph cylinder? just curios?

The cylinder's are two different sizes.. The bore size of the 20mph one is 38.0mm and the 25-30 is 38.8mm.. I don't know if there is a way to tell just from looking at the bike and not measuring it yourself but that would be one way

I def. recommend a larger carb/intake.. not more than a 16.16 if your not kitting the ped.. some portmatching if your good with the dremel... and an estoril exhaust... bi-turbo's are for the birds.. know that with an estoril comes some fitting/welding..

Also if your tapped out with sprocket options you can try and put some Tomos wheels on it.. saw them on a general 5 star the other day.. you can get a tiny rear spoke in the back but your bottom end will probably be pretty bad..

good luck

Look at the piston's dome. it will give you a number, such as 38,8 or 3-,-. That is your bore in mm.

Sometimes they do not have numbers, in which case, the only way to know is to measure it.

Add a 15:15 or a 16:16, Mamaba (or Estoril, though I personally have not tried this pipe YET) with a 38,8mm bore and a 11 X 44 gearing, and you should be somewhere around 35ish. Adjust your gearing, and you can squeeze more out of it. Do some porting, and you could probably get 'er doing 40.

I find Minarelli's aren't the fastest stock bikes out there, but they have a lot of torque/low end. If you want fast with easy and cheap mods, get a Puch.

Oh yea, and pretty much what everyone else said. Minarelli's can be funny about their air ratios.

^^^ Yup!!!! They also have 'charisma'!

amen

I ported my dr kit 43mm =60cc. The exhaust is is tapered widen the window a bit. Its nice kit and bullet proof. Yeas the mamba bolts right up. 16mm intake 24mm exhaust. These are very rare but can be found in italy. -Ed

Ed,

where in Italy?!? ha

i've searched italian ebays and all over the. i can't find them.

any hints?

These are super rare.. you wont just find it.

I can get whatever minarelli v1 parts you need. Ed
