At first I attributed the low temperature to going back to the C-16 fuel, but I had run C-16 in 2007 on the dyno and we still had to turn the bike off to let it cool in between runs. Whatever it takes to get the most power out of an all-motor Hayabusa, we are going to do.

When you are in the engine doing this modification you may as well degree your cams. In that time we learned a lot about the engine and started realizing the limiting factors in the design. See ya at the track! It is also important that you follow the complete torque sequences and torque values for the rod bolts and main bearing bolts as specified by the manufacturer or the aftermarket parts supplier. Two flavors are available: 1397cc for everyday riding and the 1430cc for track use and the occasional blow-your-friends-away street jaunt.

These costs are the best starting estimates for everything required, parts and service. Turbocharged Packages We have developed in-house custom turbocharger packages for those that desire the most out of of their engine.
No one is doing what we are doing to a Hayabusa motor. We dyno tune all engines that go out the door, on our own in-house dyno. It is all about staying on the edge without going over. We took our 230-240 head-cam-piston packages and added a 6. Where you choose to put them depends on where you want to make your power. And since that time we have not stopped making them go faster!

Hello everyone, I'm in between a rock and a hard place and I could use a little advice I have a 2007 Hayabusa 6800 original miles everything is in mint condition but I did manage to spin a rod bearing long story I could use a little help from some of the more experienced guys as to whether to rebuild the engine, purchase a low mileage Gen 1 engine or install a Gen 2 crate engine that I can get at a great price From what I understand the engine rebuild is really is not worth it but I'm also thinking about resale value when I sell the bike If I go with the Gen 1 engine I am fairly confident that I can remove and install the engine myself but if I go that route I think I might lose some value on resale?
