yes any shop can install, you would have to call the local shop and ask what they charge to do a top end and have your cylinder bored !. I think APE is the cheapest for boring.

Installed the big pistons. has way more power than stock and a lot more mid range to get me out of the corners I am truly pleased with the progress now if it would have came stock like this the b4's and the gixxers would have sold a lot more! Yahoo!

Mates here is the clearance specs for the piston kits, valve to piston clearance intake .030", valve to piston clearance exhaust .055", piston to head clearance .030". What this means is that you don't need to mill a thing! Sorry these measurements came at such a late date. hope they help someone obtain greater HP! (All measurement are in inches and if you use metric please adjust accordingly)

Good info, let us know when you get yours dialed in and on a dyno, that should sell a lot of kits!

Hi, just a quick question.  Im getting a little bored of my B4 '96 vv, its quick if i red line every gear and I can keep up with much larger capacity bike through corners etc.  

Will I notice an improvement in power, ie on a drag start from the lights, will it be noticly quicker?

I need to do a valve clearance check soon, this is why im considering it.

Do I need to do any reboring of cylinder or valves?  or is it just fact of replacing the pistions?  DO i need to replace the studding?

BTW, depending on the rider, i can beat a SV-650 with my stock b4?

People say you get a 5 Bhp increase by rejettng after fitting an exhaust, would it be worth doing this too, or instead.

cheers

Will I notice an improvement in power, ie on a drag start from the lights, will it be notably quicker?Yes bigger displacement stock is 56 it would be 59mm bore after the kit and bore job

I need to do a valve clearance check soon, this is why I'm considering it.

Do I need to do any re-boring of cylinder or valves?Re-bore yes to 59mm  or is it just fact of replacing the pistons? pistons are 3mm bigger than stock DO i need to replace the studding?No
BTW, depending on the rider, i can beat a SV-650 with my stock b4? Depending one the rider i can beat a gsxr 1000 when i talk about beating sv's I'm talking expert racers who give 100% on the track!

no dyno charts yet haven't had the time to take my bike to the dyno or the money i got a lot of projects going on right now. gaskets come with the kits (head and base gasket) for the 442 no need to modify the gaskets but for the 465 you would have to open them up a bit for the 465 its mainly for the serious racer due to  the fact that it needs liners and machine work to make them fit you are looking at 1500.00 shipped. I have one kit almost done but not installed in my bike yet i'm just running the 442. So mostly the 465 kit is out of the question but ti's possible for the right money!

nice to see some pictures  :bigok:

however it says an oem factory suzuki head gasket is included. this head gasket is made for 56mm.
can you just use the normal  head gasket or do you have to open it up?  :stickpoke:

the factory head gasket has been measured and the circumference is just big enough for the 59mm pistons and I'm talking just ti's a lucky thing cause custom head gaskets are expensive and have to be bought in bulk! So yes they fit just fine up to 59mm

Oh and FYI the head gaskets stock are .015" of an inch thick and so are the base from the factory!
