I know I haven't been posting pics for quite sometime now. Here're 2 pics; don't ask me which is stock position & which is advanced, without the timing gun working, I don't know

This is the current position which it is running now

And this is how the old stator plate looked like...

I have almost zeroed the issue to the welded part which is near the drain bolt. I had interchangeably blamed drain bolt/welded piece (guess the cracked case was welded which I've no idea when it was done). Well, I'm planning to get an inspection done soon along with Aargee coming weekend if weather permits.Originally posted by yamdoot View PostDid you pin point the leakage SRI? I have seen many RXs with hairline cracks in their crankcases.
@All: I have opened the thread of my issue in Help Me section RX135 Engine Oil leakage - Help ! . Kindly share your thoughts.

Yes, it is yet to be approved by the mods. Thanks for offering help to my issue. Overall, I had always negated the idea of opening the case due to the fact that I did not felt necessary. Hmm... let's see what would resolve this issue.Originally posted by aargee View PostI guess its yet to get approved; anyway, I've seen this overall last week; I'll bring in some tools this weekend & we'll look into it. I'll be there provided it doesn't rain & my fever subsides.

I was literally terrified of holing the piston; but then I picked up courage & then was riding. Next Monday I took the Rx to office, but the heat remained as such whether I ride for a 3 Km or 30 Km, which was little convincing.
But for sure, I've now understood on how these things work (the fundamentals) after having fixed them all by myself & can confidently open up & put things back again
While at the office, my colleague who's a junkie lends his timing gun to check & asks me to follow theory. But when I go home, the damn gun doesn't work. One week passes by fiddling to learn how it works.
Next week, I got it working, but it would keep lighting even at a plastic
; damn back to square one. But for sure, the heat atleast remains far better than what it used to be before; no issues with top end or pickup or smoothness. By now, the gear shifts are smooth, excellent idling (trust me its the same old TM28
) & things started looking good.
Coming up...experience with changing 35/35 to 60/55

@yamdoot : can u pls tell me how to check the compression?? u mean with that compression tester ??Originally posted by yamdoot View PostThe bore can be bored upto 8 oversizes. Only the bore job and the piston should be right. Indian made pistons are available upto 4th over so you have one more life left.
Regarding piston mods, it depends which piston he has used. Its usually a failure as it requires high precision machines and engineering. Hows your compression?Last edited by dpak89; 12-10-2010, 11:28 AM.

^^^ Guessed it; are you saying the pistons itself are locally made @Yamdoot? Any specific brand or are they nameless
? Obviously my next question will be, reliability & your experience?
