I need to richen up my midrange hardcore.......... its rediculously lean............. still.......... im at a 38-95 and its borderline too rich up top..... i still cant pull crap at high RPM's, im checking my valve gaps when my engine cools down.... that could be some of it........... Am i right that when you chop the diaphram it LEANS out your midrange  or am i just going crazy ? W What can i adjust to make it a little richer midrange wise...... Im very lean starting at 30 MPH to about 38-40 Or is it just my valve gaps causing me grief |

Im having some definite top speed issues. Its not my rear pulley, i replaced it with the one from my 05 and didnt notice any difference. It seems im running too lean, but im currently running a 40-95 setup, which is really wierd. Its not the pipe, ever since i chopped that diaphram spring from overoiling my airfilter its been running crappy 50+. Its not the diaphram spring..... i took it out of my 05, it still dies almost dead on 30 MPH. Its not the valve gaps as best i can tell, as the Intake is spot on.... and the exhaust is only off by maybe a teeny bit. Ill be bumping the exhaust up tommorow a size and see if that helps. Any suggestions on what i can check id be ever grateful. I feel it grabbing and struggling almost dead on at 30 MPH, ill be riding in hot and cold tommorow so hopefully that will give me an idea of what is going on as far as jetting is concerned. Will check brakes tommorow and aside from that im flat outta ideas.............. I noticed what appears to be oil on the outer ring(like the part furthest from the inside) on my sparkplug...... I also smell this funky burning smell coming from my exhaust, i figured it was just because it was new but could this be a sign of a bigger problem |

Timber, ck the oil for gas contamination. It has been the cause of erractic behavior and a few seized cranks. Flush the gas out and refill if in doubt.

If you increase your slow jet and drop your main jet you can end up the same on the top end but richer at lower speeds/RPMs. I'd switch to a 42 slow jet and then a 90 or so main.

It is definitely an air-gas mixture problem. It runs better in the heat.... but it still really struggles above 30 mph..... once i hit about 65 and it struggles downhill.... it picks up and zoom i freaking fly.............
I have a feeling my float may be gone....... ill be dissasembling the carb on Saturday.... thats gonna be a fun time....
I put some carb cleaner in there, its a little better, not much...............
This has to wait till saturday, im busy until then........... So i guess ill be changing the oil first.............. going back down to 38-85..... replacing the float with the float from my 05............ possibly the top diaphram too, we'll have to see if the float is the problem.....
She sounds freaking awesome, if i could only get the performance outta her

It seems like you're always messing with wierd aspects of your carb. Cutting the spring, the slow jet, the float, needle, diaphram etc.
Those are all such minor adjustments...obviously if your float has gotten damaged then you need to deal with it but it's likely not the problem. If your valves are good then I'd keep playing with your main and slow jets until it's good and then fine tune it with all those other adjustments.

I dont know WTH is going on..........its a driveline issue im sure of it now........... Im getting some mega belt wobble when i go from full out rev back down.... its smacks hard and goes floppy until i rev it up again.... Swapped belts, no better.......... Swapped rear clutch a while back........ i think i may be swapping the clutchs again...... i cleaned out the carb and it seemed to help a fair bit...........(totally dissasembled)...... I may end up putting that racing spring back into the rear........ Im giong uphilll and i feel the belt slipping, my revs dont drop off until i hit 30 km/h from 45 km/h..... I think thats why no matter how rich i run it down low, i cant seem to get that popping to go away.... i think im hitting the rev limiter.... as my belt slips off the face it revs up, then grabs, drops down, revs......... stupid ruckus   |

Take the variator apart, and install heavier weights, get some scotch brite and roughten the belt sliding surfeces on both fron and rear pulleys, 8-)and call me in the morning

Why it had to be crappy jetting: I swapped belts, rear pulley, variator from old ruckus, still couldnt get that stupid wobble to go away........... I swapped the floats, no different.... Swapped carb diaphrams..... Actually ran worse......... SO I finally got to ride in the freaking cold this morning (3C) and i was playing around with it friday afternoon....... until the time came to go drinking etc... so i just threw in a 38-95 and said good enough........ It freaking owned everywhere but up top........ so i was too rich............ my ruckus is stupid........... (never blame the tuner) So i swapped to leaner, im at a 38-90 right now..... the 92 seemed better up top, still only about 68 km/h top speed though........ SO VALVE GAPS MUST BE OFF!!! YES!!!! Just waiting for it to cool down enough i dont toast my hands |

Crappy jetting messing up the belt and variator behavior, if you say so

Crappy jetting messing up the belt and variator behavior, if you say so Yeah, its happened before The belt just goes slack because the engine doesnt grab right.......... it causes a big wobble...... So ive managed to overheat my engine a few times again......... I was running a 38-90 setup, swapped to a 38-92 aparently still overheated, ill have to wait till tommorow to see.......... I really have to richen up over 30 mph, i dont know why it dies dead on at that magic #, any ideas would be absolutely wonderful..............Why does it go super lean at dead on 30 mph upwards I cant seem to get any gas to it above 30 mph, no matter how big i run my main and slow jets............ its wierd....... Ive shimmed the needle up and ran a 42-95 setup and i still cant get it to go nicely......... Its actually only bad 30-40, its a little better 41-45 MPH Im tempted to drill a main jet out to 120 and stuff it in there.... the 95 APPEARS to be too rich up top, as its a little difficult to run it right into the redline. When i was running that 38-95 setup in the morning it was running very good above 50 km/h, almost old ruckus speed..... but i could hardly push it up to the redline which has now dropped to 72 km/h  Why, i dont know...... my ruckus is getting revenge on me i swear................. ill have to look into this a little tommorow, and then during the week......... i really want to get it ironed out I upped the exhaust shim and it definitely helped, and then it went to crap again after i swapped a couple jets....... wierd eh |

If its relevant............. i tried painting the airfilter, shell only, with a metallic paint........ i ended up taking it all off with Varsol if some of that got sucked into carb and then engine i didnt think it would be relevant, i used the same stuff to clean out the malossi foam filter i used to use............. I just had this crazy thought.......... could a malfunctioning PCV be causing this insane lean ness im experiencing As well....... as i think back........ the performance went awful in one day.... it was very slowly degrading............ It was kinda slowing down for a couple days when it was colder, figured it was just the cold leaning it out.......... Then one day when it was really cold in the morning......... i could barely struggle up a couple hills at about 30 km/h that i normally hold about 40 km/h up......... and i couldnt exceed 50 km/h..... This WAS BEFORE i started piddling with the diaphram and airfilter.......... Open to ideas........... i need some speed  seriously its agonizing |

Hmm, so is the pcv supposed to suck and blow air when connected to a battery......... b/c um it doesnt........ swapped the cables, still no go.....................

 No the solenoid it just suposse to let you blow thru it when op[en, it is not a pump. so connect a 12 volt power source and try to blow thru, and it should only blow when under power and not without (or the other way around)

The best solution is probably to drive it out to Ontario so I can have a look.

I can relate to the jetting as well. So far I have a Kitaco pipe, Kitaco CDI and Battlescooter variator. This weekend I put a "Pod" air-filter kit on and I can't go over 25 MPH. All the other mods made very little change (+ & -), but this one has brought the mighty Ruck to it's knees Slow (0-10) is very slow, and if I crack the throttle wide open, it just wants to shut down. I bought a couple of jet kits, so this weekend I'll try and take back what was taken...SPEED. I think I'll try the 40/78 first. |

i thought backfiring is due to overly rich!
