Late to the party apparently lol. I rockered, shortened, widened the tray and rails on my SJ last summer (http://www.x-h2o.com/index.php?threads/my-first-rn-build-complete-rebuild-shorten-and-rocker.158734/page-11). Post-ride thoughts: Amazing in every single aspect except one; keep the rocker...

I don't know much about those WR3 GP's or the VXR Pros but that pitch still seems really high for a stock SJ. I think you'd be better off getting the OEM SN impeller for super cheap...

I'm not sure of the length of the RN bolt but I also have the WDK pole bracket and the stock RN pole bolt fits it perfectly. If I have a chance I'll measure mine tonight.

So I forgot I picked up a new set of 1.5" Tall Hot Products filters and rain coats to cover them. Not sure if that will make a big difference to required pop-off. What would you guys recommend I aim for-for pop off?

So, I took apart one of my carbs, nothing stood out that would be an issue. Cleaned it all up again and reassembled, popoff @ 30psi. No leaks, holds all pressure up to around 29psi then pops around 30.

Just for reference I had 190psi in both cylinders first start, before dissassembly it was 185 in the stator side, and 190 drive side.

The water is definitely from riding. I know during a backflip attempt the engine took on a little water, but not enough to worry me at the time. Also I found a minor amount of rust around the o rings on the cylinder sealing surface to the head. The cylinder surface was flycut before install so...

Yup they held pressure, no leaking at all, soon as it hit 31-32psi, they pop and the pressure would drop to less than half and hold again.

@cookn I soda-blasted my carbs clean, carb cleaner, ultrasonic cleaned, dried, taped everything off, primed, painted, then installed the new carb kits and jets and even new low and high speed screws. The only thing I can think of is either the jetting is wrong or somehow something came loose...

@WB1994, Ya I have a popoff gauge and I tested both prior to assembly at 32psi each. I believe one was about 1 psi lower but its as close as I could get them. Sent from my HTC One_M8 using Tapatalk

Does that mean you can run stock size 760 pistons in the 701 if I bore to 84? Or are there other differences in the piston design? Sent from my HTC One_M8 using Tapatalk

@Quinc , I was doing some reading and groupk mentioned that 83 was the max safe bore on the 61x cylinder. Or 84.5 on the 62t. I'm a little skeptical going any larger, have you seen many people do larger than 83 on a 61x? Sent from my HTC One_M8 using Tapatalk

Ya the tuning I think was a combination of a few issues. One of which I think I was leaking water from my head into my combustion chamber. Either way seems like the consensus is acid, hone, rings, 1 new piston? If hone doesn't clean them up maybe bore up a size. Sent from my HTC One_M8 using...

The 44's have the built in restrictor in the carbs. I was told by a few people that it was unnecessary to run another in the line.

Heres Pics of the damage, repairable with hone and new rings? Do I need a new piston too? I'm already at max bore for the 61x apparently. Sent from my HTC One_M8 using Tapatalk

Ya im pretty sure Ill keep the dual 44's. There shouldn't be any restrictions, the carbs were completely disassembled, carb cleaned, sonic cleaned, and all new genuine mikuni rebuild kits. Also all new fuel filters and hose. So last night I disassembled my top end and just my luck with only 15...

Not exactly sure. There's pics in my build thread. http://www.x-h2o.com/index.php?threads/158734/ Sent from my HTC One_M8 using Tapatalk

I did all the porting myself, everything is fresh rebuilt engine and carbs, and the jetting was l recommended by Jet Maniac. Just not sure where to go from here. Sent from my HTC One_M8 using Tapatalk

Well its that time of the year. Christmas is over with and its the perfect time to fix everything I screwed up rushing to get my ski done for Summer 2015 (or Fall should I say). So last night I pulled my motor out and so begins the teardown to see if I can find anything wrong as it was running...

110 Pilots, 115 Mains, 2.0 N/S, 115g springs, 30-32psi popoff tested, ~1.5 turns out on HS, ~1.5 turns out on LS. No carbon on the pistons at all which to me meant rich so I tried leaning it out and then it wouldnt idle properly. Its idling rough, hesitation down low, however runs amazing top...
