Experience with DP674 pistons?

Have the old girl torn down (except for the crankcase just yet) and am about to start cleaning. She's a '79. I've half a mind to replace the stock pistons with the DP674 but for all the pictures and mentions I can find of these I can't locate any real specific info. The Dynoman site doesn't say much...

Complete gasket set reco

Pulling the 1979 CB650 apart...all the way apart. Want to get her sealed up nice and tight when the time comes. There seems to be a lot of discussion out there about the buying/not buying certain sets from certain places but I'd very much like to get a complete set of gaskets. Who here has purchased...

Re: Carb questions

Re: Carb questions

Also, what steps up should I take in size as I attempt to dial it in? 122? 125? 128?

Re: Carb questions

Awesome answers guys. Thanks. I didn't get any info on the brand or type of jets though. I was looking here: http://www.jetsrus.com/a_jet_kit_street/honda_650_CB650z.html - Does anyone have experience with this brand? - Any clue what the difference is or if I should have a preference for GENUINE ver...

Re: Carb questions

Ah, I did find this little gem. Not sure why I missed it in my earlier search: http://www.hondacb650.com/viewtopic.php?f=4&t=773 Helps a lot, though 90-120 seems like a big jump. Am I crazy? Does 120 maybe feel like a good place to start and maybe grab a couple sizes smaller or larger? A few oth...

Carb questions

Hello all, first post on this board. I recently picked up a '79 650 as a project after finishing a super cool little CB100 (now 200) for my wife. Before I decide what I'm REALLY going to do the bike I'd like to get it running well. So far I've done the basics: sprockets, chain, battery, tires, exhau...
