So my ruckus has been running a bit funky in the rain lately, actually its been rain/hail = SUCK!!!!! There was almost 2" on the road about 10 km's from where i was, i got lucky i didnt get caught in it, it was pretty solid pebble sized hail too...... It seems to be running worse in the midrange when colder, like i said though, its been running funky the last 2 days.... Ill try tommorow when its warm on my way home, it seems to be running worse in the cold, which would indicate too lean in the midrange, it seems a touch worse on top too, though again its hard to tell. I think ill give the 38-85 a shot, eval on the top VS the 40-82, and set up my low end according to that... If the 40-82 is better, i think im gonna chop a spring or 2 off the diaphram spring, i still have to do this idle mixture adjustment...... I need a how to on this fancy IMS adjustment tool  |

Hopefully the 38/85 is a solid for you as it is for me....any pics of the IMS tool Chanito? Maybe I could sell those too...

Ok, so heres the lowdown
40-82 Setup
Rich off the line - When it cools down, i can give it full throttle and it just lightly bogs
Lean Midrange - Its faster when its warm than cold
Lean Up Top - Its got less go power when its cold

Ok, so some of my problems may have been caused by the stupid PCV thing where the cam tensioner is forgetting to be put back on. I put it back on, went to the 38-85 and HOLY S***!!! The acceleration, the midrange, the top end..... Its a touch rich right at the very top, it stutters at about 69, then heads up to 71 again..... Ill be doing a full test tommorow morning when its cold, seeing if this is good or not, and then throwing the Polini in so i can start ripping things up..... I still have this dead spot when i crack it from idle, but it only goes up to about 10 km/h, then accelerates like mad!!!!
I tried the 38-82 combo, and again the stutter at 69 is gone, but it seems gutless up to that point above 60...... with the 38-85 i was cruising at 71 up a fairly substantial hill, i had a pretty solid tailwind but still amazing

38/85  Everyone's doing it  Hopefully the idle mix screw can sort out your launches 0-10km/hr. From 69 to 71 km/hr you might just be hitting the redline and losing some power...I hit the redline at 68 stock...or you might just be revving out of the power band. I vote you try it out for another day or two and then if it's still pretty good toss the Polini in and go Zuma hunting ;D |

Done the ol eval, i may still play with it some more, gotta see how my 35-85-Shim setup works in the cold. The 35-82 Shim only could get about 67 km/h on the flat, decent midrange, not great Tried a 35-85 Shim, only about 69 km/h on the top end I think my valve gaps are off, that could be causing that lag at 69 km/h, i noticed the dreaded ticking when i started er up warm..... Will check later on tommorow when my engines cold Yes, im going back to the 38-85 as the performance on the top is most likely due to the valve gaps, im still waiting for it to cool off, had to go to work in the morning..... I havent gone back to the 40-82 to see if the topend is still there, i wanna check the gaps first, the 38-85 all i need is a touch of an adjustment on the IMS and ill be ZOOMIN!! |

Ahoy, well..... when i put too thick of a shim on the exhaust, despite the fact thats what the gapping called for, as its kinda running crappy all the way, the lag from 0-10 km/h is gone. Ill be dropping it down to a size and hopefully ill be bombing.... I still have to keep trying out the 38-85, but i think its most likely the ticket

Stupid Ruckus, your confusing me so....... When i threw in what the gapping called for on the exhaust, it seemed way to rich up top, so i figured id drop the main, dropped it all the way down to a 78, then BAM!!! at about 71 the engine overheat light came on...... Ive gone back to the shims i have before, with the 38-85 setup, still no good, the coolant light keeps coming on. With the 78 setup one of the coolant hoses to the carb came out.... this is bad...... i put it back, i just bled the air outta the system again...... after it overheated about 5 times......the 38-85 isnt doing much performance wise now...... confused  i know i am.... ill be getting the one size thicker shim from the dealer tommorow, now all i have to do is stop my engine from overheating..... It was running w/o overheating for almost 2 weeks, now as soon as i go back to the cursed 78 main, everything falls apart... im tempted to just ride it out, as i cant think of anything to do to stop it..... im lettin her cool off right now, until i try and head up to work 20 km's to grab one of my clubs to get it regripped, ill have a better idea after a little ride..... The 78 setup was put in yesterday, ive been running the 85 setup since late yesterday afternoon |

You're really jumping around....if my Ruckus is running crappy a still leave it for a few days to form a hypothesis on the problem and check that hypothisis in different conditions (ie. hot days and cold days).
Your valves shims can hurt your top end if they are way off but other than that the difference shouldn't be noticable. I say wait until you get your shims dialed and then go back into the jetting. Keep pulling the spark plug and checking that. My 38/85 is working great. On a day with a bit of wind I cruise sitting up around 66-68 but yesterday was dead calm and once my engine was warmed up I could hit the 73.5km/hr redline without tucking...that's with the Polini of course.

Im back to the shims i had before, its just the exhaust thats out by about .025, which isnt too bad.. The 38-85 is too rich throughout, im sure of it now, ive ridden it for 3 days now, it hasnt gotten any better, the first day when i first put them in i was freaking rippin, i had a couple of you 0-20 times in the 4 second range and now i crave the speed and accel I think i may go back to the 35 slow, and see what i can work from there, this 38 and onwards is really not working for me, i really dont understand why..... Its 25C out here, and my rucki gargles off the line, midrange, and then a touch right up at the top..... Since ive already tried the 38-82 and it sucked, i think im gonna drop down to the 35, hopefully things go well, will post notes as i go along FINALLY NO ENGINE OVERHEAT!!!! Why Turns out the stuff i bought that said premixed most likely wasnt, Celsius extended life antifreeze, it said premixed when i bought it, however looking on the back it seemed to have mixture ratio's. I drained the old coolant, mixed up some new stuff, put it in and it hasnt overheated yet!!!! I may have a buyer for my 05 too, one of my parents friends are looking to get a scoot for thier son, which would be cool, as hes 15 or so and id like to welcome him to the world of scooter tuning early |

Did you pull the plug with the 82 and 85 to verify that it's too rich? It very well may be but I don't think reducing the slow jet is gonna help that. Consider that the stock 35 slow jet works perfectly for the stock flows. A 35 slow jet is only gonna be the ticket if your flows from 0-15mph are very close to stock which I really doubt because the biggest difference and aftermarket intake makes is to the low end. I think you need to stay with the 38 and just reduce your main jet. I'd say pull the plug for a look and if it's black go to a 38/80 or something. I'm actually finding my idle mixture a bit rich with my 38/85 but other than that I'm slightly lean. I definately run better in 20 C weather than 10C. |

' Curses, the overheating is back  Im running a 35-82 Shim right now, its 25-28 C out The bottom, sucks its too lean, i hear popping when the engine dies Struggles up to 30 km/h and then when i twist the throttle after 30....... The midrange KICKS A**!!!!! Holy crappity batman, im flying!!! 30-60 is solid and booking.... At about 63, the performance starts getting worse...... unfortunately, and its struggling 65-71, which is really too bad..... I may try a 38 slow, or possibly an 85 main with just the shim and see how those work out Im now back to this WHERE IS THE STRAIGHT DIA!!!!! I really want to make it just a touch richer, bump my main up to 85, and i think ill be good to go.... i may pull the shim off with the 85 DIA and cut a coil or two off the diaphram |

I tried a 35-85 Shim when it cooled down to about 20 C or so, i didnt get much of an opportunity to ride it, about 5-6 mins or so.... From what i could gather from the short test...
1) Low end is alright, little bog off the line
2) Midrange is better than the 82
3) Top end isnt great, but better than the 82 shim which i topped out at 71 and couldnt hold it on flats, i topped out at about 63 on the flats, b/c i didnt have enough juice to push it up to 71
I may end up trying an 88, as the improvement from 82-85 was pretty good...... The top end isnt quite there yet..... like i said ill have a better idea once i head to work and back.... Thankfully i work early in the morning, so i can tell the cold performance, and then im done in the afternoon, so i check the hot air performance

I knew a 35 slow would be too lean....stick with a 38 or a 40 and then just keep pulling your spark plug to tell how your main jet is working. And stop using shims...they only affect your performance 0-5mph and they're so ghetto.

Everytime i shim the needle its the 30-60 km/h thats affected..... Currently running the 35-85 Shim, and really liking it thus far, good torque and power everywhere.... If the 88 makes me slower up top, ill drop back down to an 85, but right now im pretty happy..... Funny story, the 35-88 Shim is what the shop dynotuned my 05 with the cam too, would it be freaky if it was the same tune for my 06 |

Tell yourself whatever you want but the reality is the shim just lifts the needle a bit further out of the main jet so it's plugging it less at idle.  When you twist the throttle the needle quickly pulls completely out regardless and by 10mph it's 100% of the way out whether or not you've got a shim in there. All a shim does is give you a bit more gas off the line.  |

All a shim does is give you a bit more gas off the line. Wierd, as thats the only part of my performance that is sucking at the given moment , as it is too lean, i run a richer MJ it goes better... Sorry about the tone of the above comment, its just that i have now noticed that the performance on my 2 rucki's with a shimmed needle is noticeably better 30-60 for the 06 and 30-50 for the 05...... and i really dont notice anything at all as far as lag on the bottom end is concerned As far as my setup is concerned, im really liking the 35-85 Shim.... it goes well pretty much everywhere, aside from 60-63, where its running either too lean or too rich for some reason, im suspecting too rich b/c when i let go of the throttle and crack it again, it kinda gargles and then gets going.... I may try a 38-85 shim just to see how it runs compared to the 35, but im really actually fairly happy..... The one thing ive noticed is im not really fast, but i have MAD torque, my starts slightly uphill are the same as on flat ground.... Kinda gargles from 0-5 MPH, then pick up and goes from 10-20 MPH, keeps accelerating strongly from 20-37 MPH, hits the kinda dead spot at 37 MPH to 39 MPH, and then picks up and goes right up to the redline if i tuck.... The torque on my rucki is amazing, as i was carrying my 50 LB golf clubs to work today, and didnt notice a big change in acceleration  |

I don't think it's possible to get a Ruckus running good across the board once you get into rejetting so I just aim for the most important parts which are the 0-30km/hr performance off the line to keep up with traffic and then my top speed of course.
You might find your 0-5mph performance gets better once you adjust the idle mixture screw.
