Yamaha raider 1100 high comp head
i want to get a high compression head as my next mod for my raider, can anyone tell me what this will do for my ski and if its a good mod for a raider? also is rejetting a must for the high comp head?

Generally speaking, a high compression head will give you better low end throttle response/ stronger acceleration and a slight bump in top speed. But its mostly gives you stronger acceleration.

The increase in compression is one of the cheapest and best mods for any ski. Now with that being said..you have to run 150 PSI to stay pump gas safe on a Tripple...so don't go above that unless you have higher then 93 octane. The raider responds well and in terms of jetting...no change really needed...if anything just open the high's about 1/4 turn and your golden. With the increased compression...I recommend some after market F/A to remove the stock restrictive stuff. Going further...if your wanting massive bottom end power...you can also use a GP1200 stinger....but will cost ya a slight bit of top RPM over the 63M raider one.
