Ok fellas, been wanting to do engine work and been going back and forth with what I want to do. Seems I have found an option that I don't think I can pass up. I found a set of 96" take off cylinders, pistons, and heads for $300. Came off the bike with less than 100 miles on them. Question is, these should bolt right up to my tc88 correct? I am waiting on an email response as to what year they are off of. Any insight to this would be great. Would this be better than boring to a 95" or 98"? I realize 98", more cubes, more power, but this seems like a way cheaper route to take. I would have to get piston rings and all new gaskets but I am aware of that. Anything I am missing that I should be looking in to?

 

Ok i received an email response. The cylinders and heads were taken off a 2009 night train off the show room floor for a big bore and se heads. these heads do not have valves or springs. What can I expect to pay for valves and springs and where is a good place to purchase them from?

 

I did a big bore 98 upgrade to my 2001; have not had a chance to upgrade the cams yet. Going with the Andrews 37G.

As far as JUST the 98 inch upgrade, if I had to do it over, I wouldn't. Just that mod by itself isn't justified - IMHO.

I would have just gone with some Andrews 26 gear drive cams for some low end grunt and left it at that.

I'm hoping my 37G cams will give me the increase I was looking for.

Just my two-cents!

 

The bore is the same 3 5/8", the 96" has a longer stroke. It may be worth it if you wanted to get the heads ported and go with a big bore , less down time.

 

I see, i thought the bore was bigger on the 96". Being that it is the same bore and doesn't come with connecting rods I wouldn't be gaining anything. I wanted to work on it in the winter so down time doesn't hurt me. Might as well just have my jugs bored and current heads worked. Guess that answers my questions.

 

x2 the 88ci and 96ci are same bore. The 96 has slightly more stroke. IMO if your looking for more power, get a good set of cams and if you havent already done it, a full exhaust and air breather.

 

We bore the OEM cylinder to 3.937", yeilding 98" swept volume on top of the 4" stroke,(107" on top of the 4 3/8" stroke) and we were one of the first shops in the country to do so, back in 2006-2007.
Combined with one of our several levels of cylinder head work, matched to the cam that will fill the needs/wants of your riding, you'll have a smooth, powerful combo.

as long as the heads are OK,300.00 isn't a bad price just for the heads,since you've got the cylinders too,porting & boring can be done on the new set for less down time,give a little info about your riding style & what kind of power your looking for

 

That reminded me of decades ago (long before there was an "online") when I memorized the formula for finding cubic inch displacement. Still to this day... immediate recall.

Bore x Bore x Stroke x .7854 x 2 (# of cyl) = Total cubic inch displacement.

 

Oh i was totally ready to get the heads for $300, however i did get an email response and the valves and springs are not included. So i'll have what?...another $200 in valves and springs? I'm not worried about down time since i'll do it in the winter. I have to do this on a budget. I thought the 96" pistons were bigger but since they aren't this doesn't help me. I am in omaha and was planning on just driving up to de moines and having axtell bore my jugs if I go that route. If I can find valves and springs for a reasonable price those heads will be worth it as they are better than what I have without any work done to them. I do plan on getting cams. Leaning towards andrews 26 or lunati voodoo.

I just thought maybe this would be a nice easy inexpensive way to increase my cubic inch.
