Banchetta Posted January 20, 2005 Report Share Posted January 20, 2005 whats wrong with his porting? 309040[/snapback] Here we go again....Anyone got some popcorn??? Quote Link to comment Share on other sites More sharing options...
Flyin_Shee Posted January 20, 2005 Author Report Share Posted January 20, 2005 Try a richer pilot. You have the idle screws turned in all the way?? 308719[/snapback] I'll have to run outside quick and see what size my extra pilots are, considering I need to run out to my truck to get my drill battery charger anyway for my ice tires. Almost got those babies done, they look pretty nice...especially on the HiPers . I've tried both ways on the idle screws and it doesn't affect it at all. I'm completely confused about this.

Banchetta Posted January 22, 2005 Report Share Posted January 22, 2005 Try raising the needles if the pilots aren't helping...You basically have 3 circuits of jetting. Get all 3 perfect and the right combo and the shee will pull at every throttle range.. Quote Link to comment Share on other sites More sharing options...
Flyin_Shee Posted January 23, 2005 Author Report Share Posted January 23, 2005 Well, today were the ice drags...lets just say I didn't get to run. Last weekend the jetting seemed perfect, it almost ripped my arms off when I was riding it. Today rolled it off the trailer onto the lake and it seemed extremely rich. Bogs down horribly after 1/2 throttle, I then tried leaning out the needle (didn't have any mains with) and it only helped a little, if at all. I then ran it without the clamp on filters (ran pantyhose over the carbs, clamped down) and it seemed to run a little better. I am just wondering why this sudden drastic change? The temperature only changed 5-10 degrees (warmer) and we are at a 100ft increase in elevation. I am just stumped, once a friend of mine gets done working on his 416ex in the garage I will be heading out there to try and change the mains, that is if I have a smaller size. If that doesn't help out I'm going to try and see if it needs to be richened. Is there anything else that would cause this? This is the second year in a row that this thing has crapped out on me, this spring I am getting rid of this pile of sh*t! Thankfully a friend of mine let me drag his Raptor, I have never ridden anything with that much torque! Only got 74.7mph in a 1000ft drag but I wasn't used to the gearing and riding it yet, but I guess that's pretty good for about 1/5 of a mile. Of course it had a full HMF system and aftermarket cam so that might've helped out. Quote Link to comment Share on other sites More sharing options...
Banchetta Posted January 23, 2005 Report Share Posted January 23, 2005 Have you disconnected the black box above the left exhaust yet?? Quote Link to comment Share on other sites More sharing options...
Flyin_Shee Posted January 24, 2005 Author Report Share Posted January 24, 2005 Have you disconnected the black box above the left exhaust yet?? 310566[/snapback] Yep, I disconnected that a long time ago. Do you think it could be the reeds? They are still the stock ones from 2000 so I'm sure they need to be replaced soon anyway, but I was thinking that maybe decaying reeds could cause it to bog way down at half throttle. But then I come to think that it couldn't be that because if I hold it at 1/4 throttle it eventually gains RPMS and starts to kick in, but I can't push the throttle in anymore or else it will bog down....what the hell could it be?

I'm totally stumped...I'm just going to stop by the dealership tomorrow and pick up some smaller jets. Quote Link to comment Share on other sites More sharing options...
Banchetta Posted January 26, 2005 Report Share Posted January 26, 2005 larger pilots... Quote Link to comment Share on other sites More sharing options...
Flyin_Shee Posted January 26, 2005 Author Report Share Posted January 26, 2005 larger pilots... 312303[/snapback] Would it make that big of a difference? I know for a fact that it's running rich because it's fouling out the plugs if I hold it at 1/2 throttle or more. I guess tomorrow I could try that out and see what the verdict is.

Banchetta Posted January 26, 2005 Report Share Posted January 26, 2005 1/2 throttle or more is controlled by the mains.... The pilots control your idle and off idle. So if your shee starts hard and doesn't like to idle, then go to a larger pilot. It'll also help w/ hesitation when coming onto the throttle..Run your shee wide open throttle for 5-10 seconds in 6th gear, shut it down, coast to a stop and check your plugs. The tips should be a dark brown, not tan, not white, not black..Adjust your mains to your plugs. Do not adjust pilots or needles to the plugs, only the mains. If you have a plug fouling problem, then one of the circuits is running extremely rich. Could be the mains, pilots, or needles..but you have to find which one.. you can be running rich on one circuit and lean on the other. So adjust the mains like I said and give us some feedback on the idle to off idle and how well the shee starts when cold and hot, and whether you need the choke..

Flyin_Shee Posted January 27, 2005 Author Report Share Posted January 27, 2005 Is it possible that it could be a cracked reed? It seems to be only fouling bad on the right side, even though everything is the same and I've changed plugs 3 times now. The coils are new and I've tested the spark with new plugs and the spark is strong, so that's not the problem. Tomorrow if I have any time I will probably take it apart and check out the reeds, if they are cracked I guess I'll be saving up for some V-Force reeds.
