Prolly unecessary if engine is stock. No?

It's all unnecessary, but most of us don't leave our bikes like they came from the factory.
With the Carpenter exhaust and a good tune it really woke up my stock bike.

I meant the huge 4040s may yield more air than the stock engine needs and also require cutting up or removing the bearclaw.

If you really want her to breathe, the K&N RX4040 is a great option.

Thank you. Will this fit under the bear claw ?

I have ran both the K&N 2780s and the Ramair.
I have also had both setups on the dyno with the same bike.
The Ramair breathed more air and required fuel addition, hense more power, but due to atmospheric differences of the dyno run dates, just a little improvement in horsepower was resultant.
I'd say Ramair has a definite edge, but if your engine is stock, the K&N 2780s will work fine.
To me (stock engine + CES) the Ramair felt more snappy and yielded more top end.

Mine is stock engine.
Will the 2780s fit under the bearclaw ?

Also, which K&N components would fit for ATI and crank case breather ?

Hi all,

I have a R3 with

• Stock intake
• Carpenter exhaust pipe
• Cat box removed
• It currently runs on Triumph tune for TORS

I used booster plug for a a bit. Mileage dropped like a stone. Didnt like it. Removed it.
Also, removed the muffler from the carpenter exhaust pipe. Love the sound

After I did that, the idle has become rough and sometimes stalls during idle when the engine is cold. It has lot of decel pops and engine runs hot. When I pull the throttle hard, I can smell petrol

Could someone please help ...what is the best tune to use something that help with rough idling and engine running hot ?

Many thanks,
AJ
