Yamaha prebug frame up resto/mod

I’m thinking of getting those 130/70/10 low profile tyres I might use this wheel for the rear or stick with stock rear wheel, what do you guys think? I’m in the middle of tidying it up so it’s in primer at the mo but I’m going to do the wheels in that mid night sky that I used on the front lip and kick start lever

You don't really see much of the rear, on a 10" wheel.
It will lower the gearing using a low profile tyre.

I really do like the look when the lower profile tyres are used on the 10inch wheels

Food for thought I guess atm

[aeroxbud]

There are online calculators which can work out the difference.
I did think about getting some 12" jog wheels for the slider at one point. They look really good with low profile tyres. And are quite cheap to buy.

I’d really like to keep the wheels 10inch,

when you put those 70profile tyers on it gives it that banded steel wheel look

I’d probably keep the standard rear wheel but it’s fairly dented up on the rim I guess I can try the rear if it looks odd I’ll swap the tyre back

So I’ll loose some top end you think ? What do you think my set up, ball park top end would be with the fat tyers as is?

I have had 4 minarelli engines bikes over the years they all reached 50/55mph Speedo indicated can I expect that from this bws you think?

[yambws]

Checked out that Calculator from what I gather it’ll knock 5mph off at 50mph I’m guessing that Acceleration wouldn’t be affected?

[aeroxbud]

That sounds about right. I was looking at fitting a lower profile to the typhoon. And it came out about the same.
Give it a try. If you like it, just install a 10% gear up to get the top end back.

I had no idea the standard minarelli vertical engines have a restricted intake manifold

Unrestricted one on order!

[aeroxbud]

And the Aerox too.
Might as well fit better reeds while your there. 😉
I brought these bargains! www.adrenalin-pedstop.co.uk/p/Enki_R2_aluminium_reed_block_for_Minarelli_vertical_engines-2544.aspx
Oh crap. Checkout is closed!!!!

[yambws]

Won’t let me Veiw that Aeroxbud comes up with a warning about it being an impersonation of Adrenalin pedstop. I see they're closing down

I replaced the reed block with one of those cushioned rubber coated ones then fitted the reeds that came with Polini kit, carbon i believe

[yambws]

I’m interested to see the difference in this intake I ordered, it looks identical to the stock one from the picture.

Are you still running the Polini sport on your Areox ?

[aeroxbud]

I only ever had a stage 6 street race, and racing cylinder on my Aerox.
I had the Polini sport on my slider, Minarelli vertical. Did about 3,000 miles on it. But sold it end of last year.

Started to dig through my parts cupboard today,I my sons started play school so I have time now. pretty much have all I need to make up another engine! tbh eBay Inspired me to build it up after seeing the price they fetch! Thought i better take better care of what I have 🤣

Any body have any idea what this hole is for? It’s an early engine I think

[yambws]

Weather was Nice today! 13 Celsius.. took it for an mot... passed!
Very impressed with Polini kit, lots of torque. makes for a very fun ride the bike being so small! I need to sort my gps out but it went of the speedo 😂

[aeroxbud]

That's great it passed.
I really liked the Polini kit on the slider. Would go past the 60mph on the speedo.
So much torque it would always have the front wheel hovering on acceleration.
These vertical Minarelli engines are a great unit.
