Yep,I checked the MPG b4 and after on the 750.Went from 45mpg bone stock down to 43 mpg with mods.But what the heck,I only ride 25 miles a day,at 70 mph,all hi-way.And the full roll-on from 70 to slow-down-or-I'm-gonna-die has NO lag at all.AND it fires right up in all temps from 30 to 90f.It's a fun little scoot.

I have been using the EMGO 12-55754 filters on my GPz1150 for the last three years now and they work perfectly on the BS34s. They do have a lip on the inside but it is tapered and comes nowhere close to the air pilot jets. There should be some modifications made to the carbs to make them work perfectly but that is about all. Personally I hate DynoJet stuff, but that is just my opinion. I think that their needles are way substandard and too soft. Plus I hate converting to that stupid jet sizing system they have. I couldn't care less what the hole size is in the jet, but I am very interested what the flow rate is. That is what Mikuni uses. IE "127.5" jet = flow of 127.5cc/Min
