A couple of do,s and donts I would suggest to 360 owners:
Dont run high test gas--Mine runs best on regular
Dont modify airbox

Do install an aftermarket air filter(although I have switched between my stock filter and my twin air and felt no difference, I will continue with the twin air element.)
Do install the black EPI secondary spring and remove the secondary shims. (this mod definitely helped low end pickup)
Do make some type of protection for your oil radiator--I rammed two sticks through mine before I got smart and made a shield out of perforated stainless--Cut it same width as stock screen but about 4" longer to but up to winch mount(great fit, too bad Kawi didnt do this)

Green Slime your tires. (saved me a couple of time, even though I carry an airpump and plugs in my toolbox"always"
I havent compared mine to a stock 360 yet, but I also did an advanced timing key, and I am pretty sure I can smoke a stock P360.
Do change main jet, and do not buy a dial a jet--I cannot seem to get any response from dial a jet and my plug was burning perfect on full throttle with stock jet, but downsizing jet from stock 155 to a 150 increased my top speed on an uphill pull.
Do raise your needle jet--with my mods, I was playing around with the carb and had a small plastic washer in my tool drawer that fit the needle--immediately improved my mid range. I took out the washer and experimented with brass washers and my ultimate performance is with the needle shimmed at .060. The needle shim was one of the easiest mods I have done yet and I highly recommend it

While your in the carb shimming the needle,- the bottom hole on the slide (not the one the needle goes through) get a drill bit, I used a bit for drilling pop rivet holes mic'd at .125, and enlarge this hole--Best free mod yet--improved throttle response tremendously

I got tired of backfiring through exhaust when decelerating so I bumped my pilot jet from the stock 35, to a 38. No more backfiring or backing off when letting off the throttle.

 

I did the black secondary spring and it was the best 20$ I've ever spent. Just oredered a twin air filter yesterday but when I get it I'll tell you what I think. In a couple of weeks I'm going to try the jetting and the timing advance key. Madmuddin1 did the .60 jet shim and liked it. Why don't you PM him if you want more info.

now do u have to take the shims out of the secondary when u put the spring in or does it matter????

 

I couldn't quite tell what was the shims so all I did was change the spring. You will need to get a secondary spring compressor to install the spring. I just made a compressor ( it was easy to do ) but You may just want to buy one. Still I To recomend this mod.

im trying to talk mi mom into doing the spring and maybe than i can get her to let me do the carb.....now wit the spring what advantage does it give more low end pick up or topend id love to be able to pull up to a gas pump or stop by a friend that dont know what i dun yeat and beable to launch the front end up????

 

With the black spring it pulls a good bit harder on launch and the mid range but unless you have a fat friend to ride on the back your not going to pull the font end up from a dead stop. I still think you would be happy with the gains from the spring IMOP.
