All factory heads are designed to meet emission standards. So they are not the best choice when trying to get the power you crave. Your heads can be ported at Strokers or just replaced with our exchange performance heads. You will get a lot more performance out of an engine with performance heads. With the right combination of parts, you"ll be looking at about 30% more torque and horse power.
The real power is in the heads with the right combination of cam, carb, and exhaust system. We can bore the cases to make a bigger motor out of it, and we can always stroke them, that’s the easy way to get more power. We use quality S&S parts and can build any size engine you want. You can end up with a good dependable 95ci or 98ci motor. To use new and improved power, you will need a high performance ignition system, balanced to the other performance upgrades.
Answer:
Over-boring the 88ci to a 95ci may not leave you enough metal in the cylinders and they could get hot which can cause the cylinder to distort. We recommend replacing the 88ci cylinders with stock 95ci cylinders to start with, in the long run you will be happier with the engine.

Check your tire pressure once a week, and stay within the guidelines on the sidewall of the tires. Change tires when they get down to 3/32 of an inch of tread. If you are an average rider, no burnouts and such. You should get about 6,000 miles on a rear tire, and about 8,000 miles on a front tire. Another rule of thumb is two rears to one front. Most people run tires too long.
In a Twin-Cam you may notice blow-by at the breather, which leaves traces of oil down the side of your bike, usually staining the heat shields of your exhaust and dripping down the oil bag. The reason for this is, even with the standard petroleum based oil, the scavenger side of the oil pump is marginal for the motor. The oil pump cannot sump the oil out from the bottom end quickly enough which causes it to load up in the top end and flow out the breather. Your local shop can correct this by installing a Fueling Twin-Cam oiling pump.
There is more than one way to get your feet flat on the ground. There are shorter shocks for swing arm styles and several lowering kits for softails. Another way is the seat.

Gel seats are also available so you don’t have to trade comfort for cool. Then there are tires. Pick a tire with a little lower and wider profile and gain down to one inch or more.
If you are going to switch to synthetic oil you should first establish your break-in miles, somewhere around 2,500 miles. In the engine we recommend 20/60 weight high-grade synthetic oil. Some recommend 20/50 weight for all three lubrication sections of the motorcycle, but we feel it does not have adequate shear strength to protect contacting surfaces in the transmission and primary. When running synthetics you may experience oil seeps in gasket areas, this is especially common to a bike with more than break-in miles on it.
