I don't know my squish, will do a test tomorrow. My engine is out of my ski, flywheel off and being lightened :) I think I am going to be running domes which will get me closer to 180-185

Even with 195 compression on 91 octane pump gas?

Want to get some input on if it would be OK to advance the timing (about 3 degrees) with the following setup: Yamaha 62t engine w/blowsion big bore sleeves, (at 846cc) Stock Stroke 190-195 Compression (Freestyle ONLY, never ride WOT) 91 pump gas MSD Enhancer #Zero lightened stock flywheel

I got an awesome deal on a b pipe, but the manifold is a 61x, and I have a 62t cylinder My 62t cylinder is helicoiled for M8 exhaust bolts, so I will not need to drill the holes larger in the manifold. However, I know the ports are different. Will it be fine if I just bolt it up, or should I...

Do you have a pivot to pivot measurement? I have a different pole

My understanding was that taller guys go shorter poles, in general

I said generally, and for freestyle backflip riding.

Please stick to the question. My question is, on the same ski, with one tall guy and one short guy, which one would need a shorter pole, the tall guy or the short guy?

Generally speaking, if you are a tall guy, would you want a shorter or longer handle pole compared to a short guy? For freestyle backflip riding

Both numbers are pitch, the size of the impeller is not stamped on it.

Ya that's how they come now, they don't have it going straight back anymore. I had to buy a 45 degree coupler from siliconeintakes.com to get mine to work.

I am running dual cooling, 2 inlets on the exhaust manifold, with a big bore 850 motor. I live in Colorado, and the water is cold now. It doesnt get super hot ever. Out of both pissers, the water is barely warm. If I put restrictors right before the water exits out the pissers, it will make the...

I have a 5 foot steel pipe in my garage for the sole purpose of prop removal. Put your driveshaft with the spline holder tool in the vice, and use the pipe over your wrench. The prop will come right off

Alright then one that is affordable and will get the numbers correct enough

Can somebody post a link to a cheap but reliable compression tester that will fit an ada head? Thanks

When is a return line restrictor needed? For dual oem carbs (44) or just a/m carbs?

My 2016 glass RIP weighed in dead on at 80lbd with hull, turf, hood, and hardware. 55 sounds super light

Ya read through the whole thing, but still can't find what I am looking for.

So in other words leave it like it is, tap the manifold, and add a tee in one of the head-to-pipe hoses to run to a second pisser? sound good?

I only have one pisser though, I thought with dual you need 2?
