drilling oiling holes in the top of the BRP piston rods?

Regarding the oiling holes on the snow x rods, which everyone says are so great, has anyone ever drilled small oiling holes in the stock rods? I was thinking about drilling a small hole in the top of my rod, for the top end bearing. Any pros and cons?

The first question I have is why are you even concerned with this? Please note that I have no trouble with the question. You have an 800R which has no concerns with lubricating the wrist pin bearings. If there is a concern with oil distribution, it will cause the engine to break down/seize before the wrist pin. Stick with what the owners are doing to keep their two strokes alive, and you will be fine. If you want an advantage, there are dozens of checks worth while doing.

Besides, very little oil would come from this oil hole. There is much misconception to how oil flows through a needle bearing to begin even thinking of a better way to lubricate those bearings. It would take years of schooling to enter the industry and even more years of listening and grunt work before one would even begin contributing.

Again, I don't want to put down your question, because it really is a good one. It's just this type of stuff we are being fed now and then rubs me the wrong way.

I don't think I've ever heard on an upper rod bearing failure on s ski doo.
Do a search on here, there's like 2 topics with pics of aftermarket wrist-pin bearings failing.

I don't see what's wrong with the OP's question or intent. The only thing I would add is why not drill LARGE holes instead of small ones?

There would be more chance of you damaging the rod than doing any good. The surface your cutting through is the outer bearing race for the wrist pin brg. Like TT670 says, who's ever heard of a failure from lack of lubrication? The only BRP failures I've ever heard of were a batch of Pacific rim made top end brgs in a kit that took out a good bit of the engine. To save $10. $27 beaver bucks for a BRP brg. $55 for the circlip installer. An engine? $2000 Reliability? Priceless. Spend your time with your girlfriend or family. IMO that's just a sales gimmick from the makers of those rods.

Oh funny guy, Mr.Tic! How about going and convincing the Tilley hat, sandal wearing, death stick riding, kumbaya 4 stroke crowd to drill "gas port" holes in they're pistons, rather than trying to get this young 2 stroker to ruin his con rods?!!!! Ha! Where have you been all these months? Plying the intracoastal waterways on the Meridian yacht with Mrs. Tic? lol

That was a good laugh. Lots of sarcasm in those statements. You forgot the helmet Mohawk and to stand while riding!!!

i have 2 snow x rods you can buy from me instead of wrecking yours. got a remand crank instead of rebuilding it. so they are collecting dust now. 160 for both
Thank you, but like you I purchased a remand crank. I seen this post to late. Bad thing is people are so harsh on me as I am asking questions, because I am new and learning. Not impressed with the people who think everyone should be as intelligent as them. JOKE!

seeing how you are new and learning I would suggest you buy a manual and follow instructions ,and do not drill any holes anywhere

It seems a little strange that someone with limited knowledge would want to start with very advanced engine modifications. Drilling holes in internal parts of the engine is pretty extreme. Your best bet is to use the engine as the engineers designed it. It does not need any modifications.
