Thumping Experiment

A friend of mine, RE owner, is trying out this experiment on his bull. It's more than 55k kms old & burns engine oil.
I'll keep you updated on this..

@psr,
yes sir, i remember and used your syringe idea.. It helped a lot but not 100% after all boric acid becomes solid paste kinda thing na.
& thanks for other explanations

The problem with Boric acid treatment happens with old oil in bad condition,and with not well maintained engines with sludge inside...Many people do not understand the variables and if any problem crops up they would rather blame the person who recommended it,than understand the real problem.
For your Scooter I had told you clearly that only through fuel tube of carb you can use the mix as sending it through auto lube will block the pump...and in carb also it will settle to the bottom in the Float bowl and block the jets and petrol flow.....so you did know the probs you were going to face.I think I even mentioned using the Injection Syringe for the same.In a four stroker the oil pump is different and less likely to get blocked....still to keep the suspended particles to the minimum ,a NEW OIL is recommended,to aid in flow of the mix through oil pump and OIL FILTER.
All of us want a smooth engine with good initial, great top end with excellent fuel efficiency from our bikes.....very few bikes can deliver this, but our love for our bike will never let us accept it...
Many of us here are not technical,and if a mod or suggestion worked for someone we expect it to work for us also...which may not be true..The variables are too many....
Hence the warning.

thanks for your clarification sir, i do understand the risk associated with it..
Earlier my scoot's carb got almost blocked with this (whenever treated) and in a 4 stroke bike if oil pump gets blocked (!) then the beloved is gone in no time..

Beyond 15 K Kms is ok for the treatment..PLEASE REMEMBER IT IS AN EXPERIMENT THAT COMES WITH RISK of even total engine breakdown...If you do it you take the decision and risk..
Always add 20Gms per liter of engine oil. Pre-mix the Castrol 40ml 2 T oil with Medical grade Boric Acid,and add to NEW ENGINE OIL.Ride the bike as soon as you have added the mix for at least 50 Kms distance...Keep the oil with mix in engine for at least 1,000 Kms for full effect.

i've got the very same query.. My bike's 15.5k old. Want to 'treat' the engine now but, waiting for the 20k mark now plz dont ask me why!

Guys my bike has done some 15k kms. Can i use the treatment in my bike now or should i wait for some more time??

Pharmaceutical grade will do.....You must use with New oil,otherwise the Boric Acid is likely to react with old oil residue and loose it's ability.Even with New oil you will start feeling the effect after the first 100Kms if your engine had done 3o K or more...For younger engines with less mileage the effect will be felt after 500 and 1,000 Kms.

Any specification of pharmaceutical grade boric powder?

Also y a new engine oil is needed? A new engine oil will anyway make the engine run smoother making making it difficult to judge the difference. Won't adding it to old oil give me the desired result?

You require the treatment only once, and if you want you can repeat it, but with lesser amount of 10 Gms or less .

Status Update

Changed my oil at last at 5900 kms - and it STILL had some life in it...maybe another 1.5 to 2k kms, I guess, but had to change as I was planning on a pretty long ride of about 3000 kms round trip

Did not do the treatment this time - I guess one more treatment at the next oil change should be fine

Remember to change Engine oil and Oil Filter to NEW, BEFORE ADDING THE MIX....
Some Swift Diesels had poor turbo dependability,and so get additional info before going for this....The turbos in the SWIFT diesel used to fail in 5 K to 30 K Kms range,and were replaced by company as manufacturing defect.Visit Team-Bhp for more info..
The same goes for some of Ford Duratorque engine turbo..

both my car and bike have done past 10k,so i will be trying out the boric acid.If it has worked well with innova,it should work in swift D.

Will try finding the same,Thanks.

NO .....What is recommended is pharmaceutical grade and very refined without impurities and smaller in particle size.
