Oh yeah, and I run the NGK Iridium IX series DPR8EA-9 spark plugs.

 

standard heat range NGK DPR8EA-9
cold weather NGK DPR7EA-9
extended high speed NGK DPR9EA-9
They should be gapped between 0.031 to 0.040 inches

 

thank you guys very much. now, does anyone know anything about the shifter stuff off of the first post?

 

sooo, you have to buy them one at a time? and there almost $90 for the set? damn

 

the shift star is supposed to make shifting smoother instead of the usual clunk. also, supposed to help with missed shifts which can mainly happen between 1st and 2nd, sometimes falling into neutral and not getting into 2nd on the first try. i've never had much issue with shifting action on this bike, so i don't know how much improvement the shift star will over stock.

ignition advance kit/trigger increases rpm by a little and gives a little extra hp in all rpm ranges. i do not know how much but it may not be that significant.

i guess these upgrade really depend on what type of riding you plan on doing. or if you just want to have them. if you decide to get them, let us know how they work out.

if i was building an old track bike, it might entertain the idea of getting these aftermarket parts.

 

i just thought about getting them to help an old bike out. its not that much cash to spend. and who knows? may be worth it. i practically have no money into this. so 400-700 dollars isnt much

 

you don't have much into it now, but as you go along it will start to add up. then there are the ebay purchases. oh man...

 

I have had a mis-shift on occasion with my 600F.

 

another quick question.

will a 91-92 hurricane tank fit a 87 600?
and will a 1000cc 88 tank fit a 87 600?
everything 1000cc 87-89 fit a 87-89 600?

 

I think you have a much better chance with the F2 tank then you will with the tanks from the 1000cc.
