I got this method from another tuner that said allowed him to start tuning right away instead of wasting his time at the track. The only way to prevent damage is by having the rings sealing and high spots worn down. After that its off to the races.

This was a complete overhaul, all seals and shaft were in grease. The outer seals get washed and wear much faster than inners do even with water present.

It can be, the term "synthetic" is very broad these days. For two-strokes the only type that is advantageous is ester, which is not synthesized from petroleum.

A Skat large hub 9-17 with your 80MM nozzle should get you there. If it has a low port SX cylinder it will be responsive but acceleration fades quickly. An SXI cylinder will be a little softer to respond but make more power and go "scary" fast.

Yep, I adjusted the flow for 130F head temp and leaned the bottom screws to peak rpm. I was most surprised with how hot the coupler and lower case got after three hours.

The best breakin I ever had was running TCW-3 on the trailer at 2500 rpm for 3 hours.

Fixed foot holds and a short poles are perfect for low speed riding. This gets very uncomfortable when you try to ride fast for very long. Fixed steer allows the rider to put his weight down on the bars when the ski is planed. This is a lot easier on your back. Fixed steers are incredibly...

Dont use KL-100 or KL-200 in wartecraft. They are glycol based and mainly for methanol use. The problem is lack of corrosion protection. Castor tends to not mix so well with gas and leaves a bigger mess but many people love it. Maxima castor 927 has some ester in it that makes it mix much better...

ADA domes have a narrow squish with lots of taper. This makes them more forgiving with fixed timing. Raising the whole cylinder will tend to soften throttle response, sometimes by a lot.

A pump stator is not a wear item so it can last forever. Skat pumps are bi-metal and will corrode internally if any electrolyte (salt water) is present. They are assembled without sealant to ensure future business. The key is in carefully sealing the edges and water port. Even better to remove...

Im not an enhancer fan but you are very close to the stock rev limit. I would mod a stock cdi to 7500rpm.

A bigger issue is finding a suitable impeller, Skat made a 7-12 for the 700XL. A larger inlet with lower blade angles will be much more efficient in white water.

Young people are the ultimate underclass. Old people are in charge and "they" decide who rises and falls. This is based almost entirely on your families socioeconomic status. From there; athletic ability, appearance, and charisma. Cognitive ability is often very threatening to those in charge...

You wont find it at Wallmart but it is available. I didnt do the testing so I dont know how others compared.

Our lab tested a lot of over the counter grease for corrosion protection on helicopters. The clear winner was Thixogrease.

Find a stock 91-96 carb and manifold.

There were several stock hulls with 900-1000cc engines around before A/M hulls became popular. At the time everyone did only rolls so even A/M hulls were too long for flips. Our best local rider started with a full length Trinity and it always nosed in with 900 power. The same engine in a...

I wish they had developed 400-500cc twostroke bikes that did not vibrate so much and were easier to start.

I think it is a waste of time as a performance mod. Shops push any mod that they can cash in on. I have made a similar tool for adapting Kawasaki 750 impellers to 650 pumps. All that matters is that the impeller is held straight.

They would produce skis as long as "they" were in control of competition events and could exclude the everyone else. Can you race a one of a kind bike at a major AMA event?
