Should I order a custom CNC Sprocket for my Royal Enfield Himalayan 450

I was advised that ideally this Larger Sprocket should fit with the stock drivechain but they have had 2-5% cases where the owners found that their chain was too new and didn't have enough length.

I reached out to Race Factory for getting a Custom Made CNC Cut SS 49T Sprocket. They're charging ~4,000 INR which includes delivery but it takes some time as it's made to order basis.

I was advised that ideally this Larger Sprocket should fit with the stock drivechain but they have had 2-5% cases where the owners found that their chain was too new and didn't have enough length.

I haven't played with changing sprocketing in past so I would like to check with those that have. Do you think the level of adjustment available on the Chain Tensioners/Rear Axle or SwingArm Adjuster Nuts should be enough to accommodate 2 Extra set of teeth ?

In case of Abhinav Bhatt (The only video currently out there about Sprocket change) - he rides his motorbike hard on trails, etc. This likely must have stretched his stock chain enough to make it an easy fit. Mine has done just 1500km so far and I haven't yet started with off-road.

I will get the sprocket delivered for sure and I might just sit on it if it doesn't fit until there's an opportunity to tigthen the chain slack perhaps in future.

Other updates:

For now, there's some relief on the low-end with the help of FuelX Pro+ and Way2Speed AirFilter. I had it done from SpeedMonks (Mr. Ajay there did an excellent job not only with the cable management of FuelX but also other accessory cables).

I haven't had the chance to change maps on the FuelX (it's the stock map), but the difference it has brought it quite noticeable. Contrary to my previous belief that it's not going to be worth the money. I will play around with more aggressive maps soon.

The differences are quite noticeable in the aspect where the motor pulls cleanly from ~2800 to all the way upto the Redline with noticeable reduction in engine harshness and buzz. With the stock bike/AFR, you'd notice knocking when you try to pull from below 3k rpm in taller gears like 4/5/6 ,but this changes that story.

Removal of the resonator box could add some additional headroom in the top-end, but I am uncertain if that removal will be counter-productive to the bottom-end torque or not.
