Hello RX Fans,
This is the first of my posts for Hard Core 2 Stroker fans who are trying to preserve the EARTH n The Environment while still riding their 2 Stroke motorcycles.
I own the iconic Yamaha RXZ, 1997 model, 4 speed (Indian) version and the Bajaj Classic (Chetak) 1997 model. In my bid to save my 2 Strokes from the axe that comes in the form of emission norms, I tried out the Somender Singh Grooves. Amazingly my 17 year old scooter started giving me a mileage of 55KMPL, easy start and reduced cleaning of spark plugs. There was a visible difference in the exhaust emissions too.
Now, I had postponed this on my Yamaha RXZ since I didn't want to meddle with the performance settings and was not much concerned about the mileage anyway. However, I was so sad seeing the WHITE SMOKE (despite getting the best of oil pump settings and additives to my petrol) whenever I was raising the throttle. So I had to go back to what I did to my Bajaj Classic
Here are the pics that I post here to help any Yamaha RX fan to follow suit.
Remove the fuel tank and then the cylinder head
Remove the spark plug
Clean the SQUISH AREA by removing the carbon and oil deposits in it
There are 11 fins (through which air passes to cool the cylinder head)
Choose the 6th fin (from the taller side of the cylinder head which actually points towards the exhaust pipe outlet) and find the spot that is straight to the MID LINE of the sixth fin all the way upto the SQUISH AREA in the cylinder head
Make a mark with a sharp object and use a triangular file (small size) to create a groove as shown in the picture below
Do the same on the opposite side of the cylinder head in the squish area i..e., towards the tapering side
Clean the squish area again and make it free of any aluminium alloy particles that would have come as a result of the grooving
Fix the cylinder head, the spark plug and the fuel tank
Try tuning the CARB anew as the AIR FUEL mixture and the COMPRESSION RATIOs and the TUMBLE FLOW characteristics would all be a little different now
Once you get the ideal setting, you would discover that the RPM can stay very low without shutting down
Also while riding you will find that the bike DOES NOT KNOCK even when you are riding in 15KMPH in 4th gear

Hi,
ReplyDeleteI'm requesting each of the mechanics to try out this on any of the old scooters for the past 3 years (ever since I had lovely Singh Groves on my car after grooving dozens of cars). But people are scared to try this option although this is much benefitting one.
Thanks for the detailed post.
Could you Pl. publish you details so that we can discuss further on the improvements over this.
I even wanted to have Gadget man Groove to the Carb/Throttle Body along with Singh Groovy head but Gadgetman quoted $500 for the toolkit which is totally out of busdget.
Regards,
Sri
