needles/jets

[RobTheTyrant]

I know this has been beaten to death but there's one specific question regarding this that I can't seem to find.  If I rejet to a 20 pilot jet and 62.5 & 142.5 mids and mains, do I need to do anything with the needles or can I get by with the stock ones and the proper washers?  I know that Dynojet kit comes with needles and yadda yadda but I'd like to NOT have to drill anything.

i'm assuming the newer style of your carbs has similar slides and needles. if they are, and you're very certain, i'd like to swap my crappy dyno jet needles / slides for your stock slides/needles.

the carbs in question are from a 1998 model, as stated with dyno jet slides and needles.

if you want to compare pictures (assuming no one chimes in 3 seconds from now) we can do that too, but please no squirrels.

I don't want to get rid of the stock ones if I don't have to... I'd rather stay away from swapping out the needles and slides if I can.  That's what I'm asking.

oh ok. no problem, yes, yes you can.

i didn't realize i had a dynojet kit, and it never ran right (this is a idler/main carb from 98 mind you) then i rejetted a STOCK needle/slide and it was fantastic. well, right up until my boots started cracking yesterday. now i'm back to ordering parts again, waiting, blech.

Does the mixture screw have to be tampered with?

Does the mixture screw have to be tampered with?

it all depends on how it runs after the rejet. a 'plug chop' at idle, partial throttle, cruising, and WOT will tell you allot. i'd bet you will want to enrich it some. maybe the newer carbs with mid jets are better, i haven't touched one myself.

any tutorial you read about re jetting will mention 'black art' and how there is no exact science to it, other than experimentation. every carb is a little different, blah blah blah

So would it just be easier to order the Dynojet kit and have then whole thing?

[The Buddha]

Yea it would be easier, and it would be especially so if the bloody DJ will actually work.
Cool.

So in the collective experience, what works better... buying the jets I need or getting the dynojet kit and doing everything per their instructions?

I may be one in a million, but I bought the Dynojet kit, followed the instrutions, well, a friend helped... basically took over. He's one of those control freaks. Anyway, my bike has always run like a million bucks... fantastic.

That's pretty much what I'm going to do... one of the guys I ride with is a service manager at a Kawi dealership and he's going to do it as long as I have a warm place to do it and a case of beer.  I'd dive into it myself but I haven't got the time lately.  I want to make it as pain free as possible for him, that's why I'm asking.  If the Dj kit is worth it, I'll just do that but I don't want to spend 60 bucks on something that'll make my bike suck out!
