Made ya look, but honestly is there a single video of this mod anywhere?
they have been out for ages and I think it's time we start to discredit them.
I mean the people selling them must have some sort of proof they work.
i don't want a graph unless it's got a video of the dyno runs as well.

Has anyone in this whole forum seen a cbr250r with the 305cc conversion bore kit installed?
Anyone?

please post a vid..
I might even call the guys selling them to see what they have to show.. but in the mean time photos and videos please

C'mon where this Video?
I swear I haven't seen a thing and if I do I'll likely buy one of these things cause here in Japan I can ride a 250 and never need a mechanical inspection to keep it registered, but anything above 250 and I do.(mech inspection is like $300/27,000yen every 2 years..
so if I can get a mod to make my 250 a 300 I'd be willing to try it but this product has no reviews and no demonstration videos and it has been out ages,, can we safely call it a flop and that it obviously isn't a good mod?

You're awesome! Thanks so much.
Does the timing chain need to be extended? or does the cylinder height remain the same?

Can the kit can be installed alone? meaning will the bike run ok and not break if I install just the bore up kit without fuel controller or after-market muffler?

Can it be installed with just the fuel tank removed?
have you found an easy way to disconnect the fuel hose?

really looking forward to the Dyno vid,
nice bike

no need extended timing chain.
you will need atleast piggyback bro.
aftermarket exhaust is optinal.

you need to take out the engine.
i suggest you to do the porting and polishing.

use small slot screwdriver to disconnect the fuel hose. it is easy.

i will post it soon bro. thanks.

Why do you need to take the engine out? i've had the top end off mine twice with the engine in the bike.

I've been running one for 2000km, along with cams, bigger valves, port & pollished head, pcv, full high flow exhaust etc.
Works well, runs well & goes well

Can the cylinder be removed without taking out the engine?

The service manual stats that it has to be removed, even when removing the head. Since I don't see any bolts holding the block to the frame it could be doable. What are your thoughts?

Where did you get bigger valves from?

 

[BBRMotosports]

Like I said, i've had my top end off twice with the engine in the frame. It's actually pretty simple work.

Made them.
