I read somewhere that you could simply replace the cylinder heads on an xb9 and get about 1050cc total. Is this true? And if so replace them with what exactly? | ||

Its not as simple as it sounds. click here | ||

Not the heads, but the cylinders and pistons. It's a 1050 kit http://www.revperf.com/XB9-XB12/xbPerformKits.html But why? Are yours worn out? If you're going for performance, do yourself a favor, and go suspension, and track classes. http://www.traxxion.com/racingsportbikes.aspx http://www.edbargyracingschool.com/ A lot easier for the do-it-yourselfer and actually you'd be smoother, which translates to faster. For where you live, I highly recommend the suspension upgrades. If you lived in the flats, maybe engine would be the way to go, but the XB9 on these roads, is more than enough to embarrass the I4 liter boys... | ||

I plan on getting better suspension first, but What kind of improvements might I see with the 1170cc big bore kit? | ||

1050 isn't really going to buy you very much, if you want something with a lot more horsepower, then buy a 12 or 1125. The 1050 kit really only makes sense when your cylinders get wrecked because the difference in money between a couple of the 1050 kits and the stock replacements is only about $100. But as I said the gains are fairly small without head work, exhaust work, and programming work. | ||

1170 is going to require that the cases are machined, gains will be much better than the 1050 kit. But if you are going to have the case machined, you might as well go with the biggest kit available. But of course there is a downside... If you have an 07 or earlier they use a smaller crankshaft which means you are stressing it a lot more with the increased power, switching to an 08 or later crank is advised when you start making big power. You are again going to want head work, exhaust work, and computer work to get anything but a wrecked motor out of the larger kits. And you are going to spend a small fortune on these upgrades. A small fortune that could be placed into an 1125. (Message edited by Greg_E on June 19, 2011) | ||

Thank you glitch for providing those links. The cylinder head sits on top of your car’s cylinders. It seals the cylinders to form the internal combustion chambers. Cylinder heads are most prone to damage when your car runs too hot or overheats. Today, most are made of aluminum, which can warp or crack if too often exposed to excessive heat. This repair, says AOL Auto, will again cost you more than $3,000. The trick to extending the life of a cylinder head is to avoid overheating. Again, the best prevention is a regular oil and filter change. Replacing thermostats in a timely manner and flushing and replacing coolant on a regular basis will also aid in keeping the car from overheating. Moreover, cylinder head is in the list of the most expensive auto repair. Therefore, vehicle owners must know this: Preventing the four most expensive types of auto repair. Check that out for the details. |
