i also went threw and cleaned the carb and so i could also check the jetting..
main jet- 155
pilot jet- 42
stock needle on the 3rd clip positon
choke clicker- 12 clicks out
1-1/2 turns out on the air screw
i run 93 with klotz technaplate at 40:1
air temp around 70-75
elevation is 768 FT.
the manual recommends 95 or higher octane... could this be my problem? cause both problems r back with the fresh motor...the only thing i changed was the reeds to boyeson dual stage power reeds...pipe silencer everthing is stock.... i do have some spooged running down my silencer but not much... so i figure im alil rich... ill get a pic of the plug today for ya all to see...

I had to completly lean the sh*t out of this bike!! I been running at this setting all summer and just tweak the air screw when the temps change outside.
The only smoke I get is at start up otherwise I have ZERO smoke and my silencer is DRY inside. BTW the 38 pilot jet I got from a Honda dealer,Suzuki only had 45,40,35. I run the bike at 32:1 with Honda HP2 oil

I am betting it is not your jetting I bet it is that solenoid and yes, check to see that is working. I don't know how much voltage is needed to work it but I am telling you without this functioning your bike will ping like crazy. This solenoid works the timing at half throttle and up and it will be way out of time if this isn't working.

ok right on.... i went back to my stock jetting 155, 42, 3rd clip , choke at 3 turns out which is 18 clicks, and 1 1/2 on the air screw which is what procircut sugguest and went back to 32:1 and mixed 110 octane and 93 half and half and almost all signs of the pinging sound were gone an it ran pretty good today..with just alil spooge on the tip so the engine temp def came up some..i cant touch the rads for more than a second..... so i def know im on the right track to somewhere.. now knowin that soleniod has an affect on timing.. thank u .. ill check it tomorrow for sure... but i still have the bogg... its anywhere from 3/8 -0 throttle... imma try an get some video tuesday of it doing it ... maybe its just my big ass boggin the bike ... i got 85lbs on the bike..lol

dang... yea 78.53 is my cost on it ... how did u break it anyhow? lol the pindle on mine was stuck open...i just pb blasted it..let is soak an worked it out an cleaned it up an applied alil anti seize an she was good to go...or did u break the housing? i dont see how it affects timing...12 volts an the valve opens an it releases pressure i guess...

I was trying to take it apart and broke the nipple off that the vacuum line attached to. It was done for after that. I could have got one off ebay for 40 but didn't want some other piece of crap that was gummed up.
I don't know how it works but my bike was pinging just a little and once I broke it and capped off the nipple on the cylinder it is way worse so I am sure mine was stuck open too. I ordered mine from here. Where did you get a price of 78 at?
Posted 13 October 2010 - 05:33 AM
yea mine was also pinging just alil bit.... sweet i hope this works
Wow! my local guy wanted 104 for it. He is usually right on with Internet pricing but not on this. I always try to buy from him to keep the small guy in business but got to go where my wallet tells me to. Let us know how it turns out. I should be getting mine any day now. It shipped already so mail man needs to get his as$ in gear.

yea he is the cheapest so i got to ride for a second today .... the pinging is gone!!! but the bog is way worse now... and it was harder to start now today too.... took me 5 kicks when its usually one good one... today was 15-20 degrees cooler today then when i was workin on jettin it to but damn.... i can roll it on an its fine but if i just hammer on it the bog will dang near killl it...so maybe im still too rich... i got lotss of smoke...

Okay, glad your ping is gone so I know that would defiantly fix my issue. I tried to go back and see where it is you are at now, but got confused. so where are you at now with the carb, needle pos, pilot, main, air screw, choke idle?? Do you have a fresh plug in it.
