I believe it was in welcome section before. You don't get technical people there.

The cylinder is same size just bigger hole for bigger piston. I have reused pushrods on two builds. Current build cam manufacturer said it needs adjustable pushrods

Another option is boring out your cylinders cost around $250 for boring

When people first started boring they only went to 95", now they go way bigger. My last 2 build I just stayed with trusted and true 95. Nice reliabtbuild, not going to stress the rest of the bike.

I also like lower compression, mild builds. Many will disagree with these last two choices.

Port,bore, mild cam, and you will have nice non EPA compliant bike that will make more power than bigger EPA compliant bikes

Was it in 2 places? I don't think this is first thread because first thread in welcome section I told him cylinder does not get taller.

Go look, your response is in the twin-cam-motors section and not the welcome area.

The guy did post the same questions in all 3.

No, just doing my job; double posting is not allowed. The OP posted in the Welcome Area first and was advised to post in either the Twin Cam Motors or the Engine Mechanical Topic section. I replied in the Welcome Area that, of the two, the Engine Mechanical Section would be a better choice IMHO. Don't know why the OP decided to post in both but he is new to the forum and just didn't know any better; everyone has to learn the rules of the road. I also gave the OP a choice on which to delete and suggested it be the one in the Twin Cam Motors section. I would not call that overzealous.

JMHO, but I think the Twin Cam Motors section is redundant and should be deleted but others don't agree. That section was added some time back, maybe a year or so and I didn't understand why then, particulary since it was placed in the Harley Davidson Motorcycles sub-forum but WTFDIK.

I don't know if the bike is carbed or EFI; don't see either in any of his three posts. I could have missed it but re-read all three which are identical (copy/paste) and could not a reference to either.

All 03 Dynas were carbed.. They didn't go to EFI until 2004.
My bad, I thought buyers had a choice like the softails.

personally I think a forum for each motor. Personally I think people post to much in family of bike. Bike not starting is not unique to touring or Softail .

Though you get to many forums it gets spread out to much.
