Was riding around as normal this last weekend and my 1995 900 Tigershark suddenly lost top-end power. The sound of the motor running has also changed to a more hollow throaty sound. What should I start checking? -Spark is present on all 3 cylinders. I did notice while it was idling that the RPM...

I am installing an engine 640 into a Tigershark. There is a spacer washer that goes between the coupler and the engine on the crank. I am missing it.

I recently posted asking about a 640/770 engine swap. I decided to try and it and it fits! I am working with a 1998 ts640 and 1998 ts770.

Hey, I just ordered a new set of Crank seals for my tigershark and the first one I tried to put on was too large. Do I have the wrong size seals or is this maybe not the engine I thought it was? Maybe it is not the 1000? If anyone can tell me what size it is supposed to be, that would be great....

Top speed used to be around 50 mph. Me and my friend were on it cutting doughnuts and it just died, after a few min we got it started, but now once it gets to around 25 mph, it will not go any faster. Does anyone know what could be causing this? Thanks

Quick question. I picked up 2 skis and was wondering what oil to use for the 50 to 1 mix. It is obvious the manual says tigershark oil but gives no type or rating to select a different brand. Can any one give me an idea as to what type of oil? Can I use yamalube??
