Default TC88 build tips required

Hi,

I am new to HD forums.com, however I have been an avid reader of previous threads for quite some time.

I am looking for some assistance on my current build. I have started building a chopper and am using a 2005 twin cam 88A as a motor. I bought this motor with only 5 miles on it as a trail of sparks left the bike unrideable. There was some damage to the fins on both the jugs and heads so I needed to change them out.

I have purchased a set of Screamin Eagle Heads (part# 16901-99 & 16902-99). I am told that these 1999 heads will work with the 2005.

I found a set of barrels with 5 miles on them off a 2006 to use and am planning on replacing the pistons with Screamin Eagle high compression pistons (part#22156-99).

I have not selected a cam as of yet, but I have used the andrews gear drive with much success in the past.

This bike will also be equipped with a weber downdraft carb.

I am looking for any tips or comments from anyone in the KNOW. Although this is my 4th chopper build, I have not had to build an engine as of yet. Infact the last time I had my motor apart it was an 82 shovel that blew a wrist pin keeper. First HD, first weekend out. lol

I see that there is a different head gasket used after 2005, was it thicker, thinner?

Thanks in advance.

Not being familiar with those PNs, can't comment much on the heads; which design? chamber volume? valve size? etc.

Don't need the high compression pistons; if the heads have the bathtub chambers, it's better, IMHO, to get the compression with head decking and head gasket thickness; easier to control quench. The SE cast flat top pistons will work just fine.

Depending on how you ride, exhaust and headwork, there is a world of cams to choose from. I am partial to the Andrews brand and I am sure you can find one of their grinds that will work for your build. You really should select the cam first and build around it.

No experience with Weber downdrafts but I expect it will be hard to tune. The stock CV carbs are cheap, easy to tune and parts available; I would reconsider the carb choice.

Just use a Cometic MLS .030" head gasket and forget stock.

Good advice from Kirby on those Webers, and good points djl is making as well.
A great build we do here day in/day out is to re-work the OE cylinder head, and bore to 98", and combine it, with a Wood cam of our choice for your riding needs and wants.
The OE CV carb, while mundane it may seem, really and truely works very well.

Default Thanks

Great advice, yes the Weber was for the looks. These are parts that I already have to work with so I am trying to make the most out of them.

depending on who you talk to some have had great luck and power gains from the weber while others feel they are a POS.

thanks again
