As far as my experience with cb550's goes, I had a 550f with velocity stacks and an open header and I didn't have to rejet, just dropped the clips for the needles one notch, bench synced them, vacuum gauge synced them and I was able to dial them in no problem. FYI, I was concerned about the...

updates?

such awesome info fellas!! keep it coming as you find it and ill be doing the same

i will pm you...

anyone online right now with some photoshop skills? i have an idea and would like to see what it looks like on paper.

hmm, that would be pretty interesting. looking about about 1.8-1.9 r/s ratio

i was planning on using cb1100f connecting rods for this reason (assuming the big end is 38mm like the 900) no i do not, would you happen to have a copy of it? like i said im really just looking for a fun summer project.

you guys are slowly making me think of going with a short stroke 1000.

and pj, this is basically for shits and giggles, the bike its going into is going to be hardtailed and just used for around town lol.

the rod stroke ratio with cb750 rods is 1.66 and the cb1100 rods is 1.64, i think the thing im going to have to be most concerned with is pistons speeds.

Well the main reason I wanted to do the 1062 is because I think it would be a fun project to undertake and since I have another bike that I ride on a daily basis I'm in no rush to finish this one, I'm making my own frame for it too so it'll be a long time till it sees the road again.

What did you get for rwhp? My guess with the setup I'm planning on doing I should be able to get close to 100whp with a decent set of carbs.

thats the exact plan. cb750 cases and head cb900 jugs, crank, and possibly cams depends on which is better cb1100 sleeves, pistons, and con rods.

alright, so im slightly confused here now. i had a different post here a little while ago but after posting it and reading it there was no sense in it after doing the math so im going to think out loud here a little bit and i really think im going to have to get parts in front of me with some...

I'm starting with a cb750 dohc engine.

thanks pj, youre the man

any idea where i could find some definitive info as to which cam is better? ive looked all over the web and its very hard to find any info on these.

i found some info from a few different sites which stated that the cb900 cams were slightly more aggressive?

ahhh, good point, i forgot to account for the flat part around the combustion chamber which would now be at the top of the cylinder. supposedly its pretty common to bring a cb750 up to a 1080cc and this setup would net 1062cc's. i could always use the cb750k dohc head and just run cb900 cams...

well the cb750f cylinder head has 2 mm larger valves but the combustion chamber is larger than the cb750k dohc. the cb1100 had 9.8:1 compression, the cb750k dohc had 9.2:1 compression, and if my math is correct without decking the head and block im looking at 9.3:1 compression.
