    So I went to inspect the bottom & found the drain bolt area to be dry. So now its confirmed that its leaking from the crankcase. Then it striked to my mind that I'd opened the crankcover to show the clutch assy & how the gear main shaft is located earlier that day & hadn't replaced the gasket as I didn't have any.

    Run now!!! I dashed to the spare parts shop, picked up a gasket assy along with the drain bolt oil seal.

    Saturday morning, drained up the oil once again, opened up the side case, replaced the gasket & VOILA!!! The leak stopped

    Used fingers all the time except when tightening & first turn when removing

    Service at weekend

    Last Friday we (yes WE) had a service for Rx at 6700 Kms to precise. Thanks to Sri (SriramEFunds) to get a Motul 5100 for me. I'll reserve the comments of the engine later, but for now focus on service.
    - Found that one of the nut had fallen off the right L bracket; must be due to loose fitting when I experiemented with the exhaust
    - Carbs, I didn't clean much as its already cleaned up every now & then
    - Cleaned air filter
    - Drained transmission oil & filled with Motul 5100
    - Checked all lightings & since everything was intact, didn't have to do anything
    - Cleaned up chain cover & applied old 2T oil to chain for lubrication
    - Since the brakes were intact, didn't want to touch & mess up them
    - Clutch cable was changed recently & the play was also in good shape
    - Removed mud from under the chassis

    Now to the experience of Motul - I could notice the smoothness right after the 1st gear & I'd say way too smooth. It only got better over time. Never seen such a smooth performance ever in my 13+ years. Truly Motul 5100 is an awesome engine oil well suited for Rx. I don't know if any other company can provide such a quality (Sri, you know which one I'm talking about ), but I don't want to change again from Motul. Its simply awesome though its a 10W40.

    Finally when all the work was over it was around 3PM (There was much more drama too ). After an hour to two, I notice a tiny pool of oil on the ground. Now I'm scared...the engine is leaking oil...but how? I'm beginning to think...

    Yeah, that would be of great help

    Would suggest you to get some run to resolve the issue. I had also felt the same when I got my silencer was given some sand blast treatment last year. If you notice or not, after sand blasting is done, grunt tone emitted rather than loud, i meant depth! After you do 2 weeks of office ride would tone a bit.

    On the lighter side, use loose 2t oil, best treatment to get carbon deposit even with little ride...lol

    It can be because of two reasons.
    1. sandblasting has caused the metal to thin out causing less sound suppression.
    2. your muffler tube is fake or altered.

    @Sri - Actamol is perfectly right; the plug reads good, which means the mixture is just right. But does that justify the sweet spot? I don't know.

    Last weekend, I'd sometime, so I picked up my old Rx exhaust, got it sand blasted & chromed & fixed it on the same day. Man!!! the beat is so pathetic at idle & the sound is way too loud!!! Very embarassing to ride an Rx with that kind of sound

    Here's the output & finishing of the chromed exhaust before fitting.

    It's the same plug.

    Sorry, I was playing around the exposure a bit and that happened to be slightly brighter. The engine heat is not adverse. Offcourse, might not want to put my hand on the head to feel though. As I mentioned, for the time being pre-mixing fuel. If not for the third picture, does the plug reads good?
    Let me know if you need more pictures(this time would not play around with exposure ).

    Anyways, after doing about 100 kms or so, have taken a plug reading. Take a look at it and let me know if I need to adjust.
