    Hey Eric,

    Glad to see you are paying attention. The dealer said they adjusted the RIVA sponsons because one was installed a little higher than the other. Now the ski is a little skiddish in the slop yesterday instead of tracking rock steady. It made me a little nervous.

    Well, the ski is smooth alright, but ... no balls. Top rpms is now 8,050 and it takes a while to get there. It feels like my neighbors HO. My stock SVHO was faster! Jerry says its probably "boost leak". I will check the hose this morning and get back to you all.

    At this point I would make the trip to take it to a guru. Long drive but in the long run you would have your ski running like it should and have it this season. Not to knock Hughes but I spent about an hour with the mechanics when I looked at a GP1800. They are nice guys but they are outboard mechanics. He was talking to me about having your timing chain off a tooth and the time they were going to charge you to correct it. I was explaining to them how the LC13 worked and I have not had a ski since 2013, just read the forum. I am concerned that even once you get the ski to the speed/rpm you want, you are going to blow it all to s#!t. Those guys don't understand any of the parts you are putting on that thing. They just follow "A, B, C" and think they are done. You, me and everyone on here knows that is not the case. Load that bad boy up and take it to an experienced tuner. May be inconvenient but once it is done I imagine you will have the baddest MF'r on SML!

    What did they say exactly about charging me about correcting the timing chain mistake they made?

    I wish I knew of a great Yami high perf mechanic within 50-100 miles of here ... I would be there next week

    Are there any videos on this forum on how to tighten the hoses for boost leak and how to test for boost leak?

    I don't remember exactly what they were saying about the cost of the timing chain. I also don't believe they were trying to take advantage of you. I just don't think they are the right guys to be working on your ski.

    I am not positive what was causing all these problems, but we think it was the combination of the siphon tube and that fact that the Lucky13 was not installed properly and was vibrating and possible hitting the siphon tube. After the Dealer returned the ski to me it ran smooth but was way down on power. I could only get 8,050rpms and poor acceleration. Jerry suggested that it is probably a "boost leak" and we should check all the hoses.


    This morning my good friend "Magnummmmmmmmmm"(Johnathan) came over and climbed into my ski and checked every hose, tube, wire, supercharger spin and blowoff valve. He finally found a few hoses were not as tight as they could be and put the death screw on them Then he checked out the blowoff valve and it started screaching like it should, so we now know we had a serious boost leak and the F1 and blow off valve are now doing their jobs.


    So without further adoo, Johnathan took the beast for a several runs. Here is the parameters: With the Solas 13/20, L13 no spacer, temp 70F, 6 bars of fuel, rider weight 200lb, almost no humidity, slight ripple, 800' elevation ... Johnathan got 8,640rpms and ballistic power for several pulls. I tried and got the same 8,640rpms but not as high a speed following Johnathan's runs. He is a really good rider You have to remember we are at 800' elevation which makes a significant difference in power and speed. It should be noted that the hole shot is not to be believed. The ski sounds like a fuely dragster coming out of the hole at 10,000rpms. I like the acceleration more than I like the top speed.


    I really don't want to get any higher than 8,600rpms because I want this puppy to live. If the weather gets really hot and muggy, I can switch to my 13/18 and then play with L13 spacers ... but for now I am a happy camper
