06 Street Bob Stage 2,3 upgrade help?
06 Street Bob Stage 2,3 upgrade help?
I have a 06 street bob, V&H Black Big Radius, Thundermax with Autotune,RSD Venturi air cleaner with K&N filter. Looking to upgrade cam and cylinders, trying to not do heads because I hear your reliability go's down after. I know the 06 dynas can except the later years cams 96"ci. I already ordered a heavy duty clutch spring. I was thinking S&S 97" Big bore Kit with a S&S 570 or 585 easy start cam, and .030 head gaskets to raise the compression to 9.9. Do you think my reliability would go downhill with this settup. I usually don't redline my motor so I would like more usable torque up to 5700 rpm or so. Any suggestions? I won't change my pipes for more performance either they look great and cost alot. I could just bore my cylinders but I like that the S&S Kit has heavier duty liners and if I go 98" Kit there is no room for a rebuild. I don't know if I would need adjustable pushrods with this settup or not, if I do whats the best 1's to get and the correct size. I think the 06 Dynas also already have hydralic tensioners for the chain drive cam, so I might just buy replace the shoes ,12,500 miles on the bike now. I was thinking a Axtell TC oil bypass might be a good idea too. Another question I know the S&S Kit does not require rebalancing of the motor, if I went with a 95" Kit with Cp forged 10.5 pistons would I need to rebalance. 1 shop told me it was $2,000 to rebalance add that to the other parts and I could just get a new bigger V twin engine.

Well my opinion or remarks i guess is the 570 cam do good. But i wouldn't want the easy start cam version i just not sold on how reliable that pivot gizzmo thing is . Second i question if the .030 head gasket alone will get you to that 9.9 compression. I have a Andrews 57H cam in my motor and like if however i am consider taking .040 off the heads to get me a boost along with the .030 gasket. That be a total of .055 closer now that should bump the comp some. As far as reliability goes my only fear was as i stated the easy start feature is all i be nervous over

You have some mis-information in there. I like the easy start cams from s&s. You will not need adjustable pushrods if you go with a cam that has the same base circle as the stock cams. I like s&s parts but there is a benefit to having your cylinders bored and fit to the pitsons (cost). There are a ton of vendors that are members here that can hook you up for that. I myself, am going through this process right now. I bought the se 95 kit and 203 cams for a mild build. I am having my flywheels trued and welded and also the Timken bearing conversion done for reliability. Some say the crank work is not necessary but I didn't want to chance it and I had the extra coin. It was either spend the money on crank work or headwork. I figured it was easier to do the crankwork now then later. And when I do headwork in the future I will change the cams up to suite it. Your choice is key

S&S has it listed that the compression with the stock heads is 9.7. and if you add a thinner gasket .030 you add .2 compression. I have to do some more research on the cams and maybe I don't need the ez start with only 9.9 compression. I emailed S&S saturday they should get back to me tommoro.
And i am just kind of **** about the EZ start thing. My fears are me thinking either the little pin that holds that rocker would fail and cause a BIG problem or that down the road some sort of build up of gunk will get in there and not let the cam close. Probably both unfounded things. But i try to eliminate any extra stuff that could brake because for me it always happens in the worst damned places lol.
Ordered Build parts
Getting the cylinders bored to 3.875 95ci at a machine shop in town that came highly recommented by my local chopper shop, Motor Tech,$100 for the bore and hone. WISECO Vt Piston Kit 95Ci Domed Standard Bore 3875In 10.5:1 Comprsn VTwin VT2709 $314 ebay, Smiths quick install adjustable pushrods $144,Barnett Heavy Duty clutch spring $30, S&S 585 Easy Start cam $334 ebay, S&S Cycle Premium High-Performance Tappet without HL2T Kit 330-0175 $224 ebay, Baisley LMR Oil Pressure Spring $17.50 $1,163 total for parts plus whatever Galley Motorworks charges for the install. Should get some nice power and torque I think with this build.
