Yeah so hey guys. I just came here for some advice for an international student here in malaysia that barely knows how to speak the language but has a passion for motorcycles.

So my bike is a Modenas MR1 2017 with around 34K km milage. At around 32K i decided to modify the block.
The mods done on my motorcycle are:
- Block 53 Espada
- Piston Espada
- High Cam Espada
- CDI BRT
- Sprocket 14T/36T
- Adjustable Cam Sprocket Arata
- Apido Exhaust 28mm Manifold
- Uma Coil Plug

Before installing the exhaust, coil plug and adjustable cam sprocket my top speed is 97KM on waze and 120 on my meter. I asked a few people and they have the same setup and have higher top speeds. I still didnt try the topspeed after the recent mods due to covid-19 and the roadblocks and all.

Many people advised me to change sprocket to 15/33, some say 15/36 or something.

What could I do to my bike to get a reasonable pick-up and also a higher topspeed? Is it a sprocket change? or is it something else? Keep in mind im a big guy weighing 93Kg.

I need your help yall!

welcome to Modenas club bro, my daily ride machine to Genting Highlands been using since 5 years ago, really great bike and cheap maintenance 👍

thanks bro!

is better u dyno your mr1 first just to see the powerband and decide which sproket size suitable for your ride preference.

how much would it be to dyno?
