Awesome, thanks so much guys for the input. It's nice to have somebody else take a look at it. What a relief. I agree, that F/A is pretty tall and must make it look worse than it is. My local ski tuner said when it's running rich it can run a little rough as well. :bananalama:

I'm trying to determine if there is something wrong with my engine or if this amount of shaking is normal. To preface, this is my old engine completely rebuilt, new crank, bored to match the new pistons on Aqua's old ported 61x cylinder. It has about 5 hours on it and it's probably running a...

Thanks man. I have those I just wanted to be sure.

Does anybody have the original Riva install instructions? I had printed out a set that I got from someone on x-h20 and they got wet and ruined. Could somebody post the scanned images or tell me where I could find a copy to print. I checked and Riva does not have them listed in their instructions...

I would get a toploader. You might lose a little top end, but who cares, you probably want to stay hooked up more than anything. I have tried a number of different intake grates on my 440, 650sx and now my Superjet, the toploader is the only type that I really felt made a significant difference...

I bought a used cylinder from him. Very nice guy, good price. Cylinder looks good too. Thanks, Adam

I'm sure this means I need to rebuild either the pump of the driveshaft housing but I just wanted to throw out that I had just greased the pump this morning before I rode. Can too much grease cause the shaft carrier/housing to make a whining noise? My ski has been sitting since Oct of 08 but it...

I've been trying to get to the racelogic website so I could order a freeride port template but I can't pull the site up. Does anybody know if they are still around?

Pro-tec sounds good. I know they have tons of Yamaha stuff, I didn't know they did engine building and all that stuff. Thanks guys adam

I only know of GroupK and somebody mentioned Team Scream. Are there any others. It's a 61x.

I paid $650 for my 93. It had a bad CDI, but would still run up to the mid rpm range, then would sputter. I think anything over $1000 is too high but I guess it all depends on the condition.

I was also told not to run water injection. You can still get the installation instructions on the Factory pipe website. It's at the bottom right. All you need to know to get it set up.

I pretty much have the setup above except with a R&D 35cc rec head and I have not installed a lightened flywheel. I'm running a mikuni 177.5 main jet in the stinger and it seems to hit real hard. I've ridden a 96 with a b-pipe, msd cdi and water injection and riva 35cc head. This ski had a 14/17...

I'm going to see if I can find a used 61x. I don't keep my ski at my house so I need to be able to take a lightened flywheel up to the lake and swap it out. Anybody have a good 61x flywheel they want to get rid of?

I don't think I'm over propped. with teh 12/17 skat. Can the boysen replacement reeds cause any issues? Does anybody make a lightweight flywheel for the 61x? TBM, Jetnetics both have them for the 62t, 64x. Haven't found one yet for the 61x.

It does pull hard but but I guess you always want a little more

I'm okay with not maxing it out. I couldn't use all that power anyways. I'm just a little 128lb fella. Just want to get as much as I can within reason. I've learned a lot in the last couple of days about my options. I just didn't think I really needed a larger carb as this point. But I guess you...

Steeldog and crammit, thanks for the caution on the advance timing. I really do like to err on the side of caution so I'll just stick with the stock timing. As for a larger carb, I do agree that it would be a good move, but since I'm probably not going to do any port work right now or raise...

Yamacat, do you remember what you paid for the blackjack? I appreciate the mod list, looks like I'm heading toward a very similar setup. Thanks guys for all the feedback. I'm not a surfrider but I do hit the lake a few times a month and I want my square to have extreme punch. I'm pleased with...

Been reading up on the jetworks fcv. I have the non-pro version, yeah I guess that makes me a poon. I saw a few posts cautioning using the fcv with a dry pipe. I thought that it would need to be installed inline between the chamber to stinger line. I'm already running a 177.5 jet in the stinger...
