thinking about using CP Pistons 9.5:1 pistons which cam would be good with this set up, SE 211 SE 255 ?

 

Call up Headquarters and talk to them.

 

We should guess what year and model your bike is???

+2 on contacting Head-Quarters about cams. Check-out their website for info on cam selection.

 

What ever you do, don't call Head-Quarters...well unless you want to spend some money and get a REALLY nice cam set for your scoot! Seriously though, Doug is a wealth of knowledge and will get you headed in the right direction depending on what you are trying to accomplish. Head-Quarters is the call to make without a doubt!

 

I hear good things about the SE211's, but if you want a nice boost in low-end TQ and midrange performance, along with a modest improvement in peak HP, consider the SE255's. They make the power where I and most other touring bikers need it, below 4K RPM's--but they won't make you top dog at the pool hall for big HP numbers.

The SE211's shift the curve to the right a bit and may reduce low-end some without more compression, but it's a good cam to consider, especially with a modest compression increase like you suggest. The SE255's don't need more compression, but the SE Stage II kit (103) includes this cam set with 9.5 flat-tops.

I put the SE255's in my otherwise stock TC96 and I'm very pleased with the outcome. I also have the Fuel Moto Power Package (PCV-AT, AC, and Dyno-Tuned Jackpot mufflers).

 

I'm running a set of Wood's TW-6-6 Cam's in my '09 SG with a 2 into 1 exhaust, Big Sucker intake and a PCV-AT and I'm very happy with the results......Rich

 

You may need more compresion for the SE211 to work right. Look at adding a Cometic head gasket .030 thick. I got amazing results with it using the SE251 Cams

 

What does this gasket do vrs the stock gasket???

 

.030 cometic MLS(multi layer steel) will build compresion. With my build with cast flat top SE pistons My CCP is 195. Take a look at their web site
