I am having the dealer install the SE hydraulic tensioner kit with the high volume oil pump. I want to upgrade cams and they suggested the SE255? I have a 2002 FXDWG3 dyna TC88.I don't know much about cams so any advise would help.

 

I dont know anything about the SE255 but When I was considering cams I was given advice that if all you do is the cams the S&S 509's are the bees Knees.

 

I think they are equal to the SE 204 cams that lift .508 the original valve springs wont accommodate any lift past .510

 

The 255s are great torque cams. I have them in my TriGlide. They are great at getting a big heavy trike going. But, there might be better choose con a Dyna...such as SE204s if you are staying with Harley brand. Check out the comparisons attached, that came from the Haroey site. Pick the cams that fit your riding style best.

 

The 255 has more grunt downstairs and and runs out a bit sooner than the 204 although the 204 comes on a bit later.

 

2002 valve springs are said to be limited to .510" lift but many have run .525" lift cams with the early springs. The early springs might coil bind at .556" lift of the SE255 cams. Additionally, the early heads won't benefit much from the added lift, so why not stick with a .510" lift cam and avoid any potential issues that offer no benefit? Andrews 21, S&S 509 or, as has been mentioned, the SE204. Personally, I would have not spent the money on the hydro tensioner/pump upgrade; a set of CYCO shoes and Baisley spring is all that is needed. Spend the savings on some headwork and cams; much better bang for the buck..............

 

Thanks for all the input. I am going to go with the 204 cams I think. I don't want to cause any issues.

 

Good advise DJl thanks!

 

S&S .509's or a set of Andrews 21's for a plug and play cam for an 88".

Had the Andrews 21 in my 2003 Fatboy, pulled like a tractor. If you like torque that's the cam for an 88"
