This is just a general overall inquiry and I know that jetting,riding style plus overall chassis setup plays into this too but has anyone noticed their fuel mileage decrease with heel clickers?My sled used to be one of if not the best one,in my particular riding group,on gas but not any more.I've long traveled it with the Apex skid which sucks power,the jetting is 01 specs with the 2000 ignition conversion but I struggle to get 10 mpg with this sled.The very best I ever got was 14 and I see reports from guys on here that still get 12-14 mpg,and yes that's no doubt on a more or less stock sled.How much of my mpg loss can I attribute to the aggressive clutching setup without taking into account the other things I've changed?My riding style is pretty much the same as when I first started riding this sled so it's not like I'm completely comparing apples to oranges.
did you put your valves in upside down, are they working correctly, did you install a new track and not cut the notches for the guards? This is the bulk of fuel mileage problems i see with srx and vipers.
srx should get you 12-16, maybe 10 if your traveling above 100 for the entire tank and then that is low.

Well the valves are in right,just cleaned about a week ago are functioning correct.Track has been on the sled for about 10 years and is a .910 lug so it has clearance.
Maybe the higher engagement might have something to do with it as well. I believe with H/C you engage at about 4400-4600. Depends on spring and setup. I never got a chance to see the difference in mine. It blew the belt and took the clutch out. Waiting on another clutch to try another setup.
That is a little high an engagement for trail riding but I dont think that is your issue. What spring is in the secondary, sometimes people talk you into some huge back spring, but still, ???
that .920 track, is it relieved for gaurds? Your sled is designed around a 3/4in track, anything above that will rub. Look up under your tunnel where your tank is, this bows down over time and makes the guards rub worse. This is why I recommend using full length polaris style aluminum guards. They help hold your gas tank from pushing down on your track.
also, swap cdi boxes, I have heard of some viper boxes having straight timing, no advance. sled just doesn't have the power or fuel mileage compared to others.
What is your gearing?

I can't for the life of me remember the engagement rpm but I don't think it's a high as 4600.Gearing is 21/39 I believe,it's got a V Max reverse kit in it hence the 39 bottom gear.Green secondary spring wrapped at 70° with a 50/39 helix and clickers tuned in for 83-8400.I have actually been meaning to swap the plastic tunnel guards for 1" aluminum tubing for a couple of years now but......... As far as the track,with the miles I have on it I would think it'd been wore in long before now,I can't hear or feel any rubbing while the sled is moving,and the front protectors are just the Kimpex ones and they're not even as wide as the aluminum ones from Yamaha.I do have a spare cdi actually and the first chance I get I'll swap it out and see if it makes any difference.
For $chitz and giggles, 2002 with ported motor, widened raised front end, Mono rear, Ice Ripper XT track, reverse chaincase 23/39(?) pulled 13.2 MPG over the weekend....farm fields, woods, no open lake running, pretty decent.
Well I see your geared taller than I am,I wonder how much of a difference I would see if I stuck a 22 top gear back in the case?I just happen to have one,and I think I'll buy a new red heelclicker spring too.I trail ride with my son a lot these days and that means trail speeds are usually around the 40-45 mph mark,it's not like I'm pounding this sled,like I would be if I was riding with my buds.
I don't have any numbers, and this doesn't relate to heel clickers, but I burn more fuel riding with my boy and his ET250 than I do with my buds. We're lucky to top out above 40mph. Speed is the biggest killer of fuel economy over the road but on a sled I'm not so sure.
I also burned a lot more than I expected towing him and his 7 team mates at once on kiddy sleds around the bay last weekend. It's the first time I ever ran my sled out of fuel... luckily in the driveway at the end of the day.

i have a 2000 srx that is stock with a one inch lug track, no studs. my friend has a 2002 srx, clutched and piped with a one inch lug, fully studded. at the pumps he usually takes almost a gallon more fuel traveling the same trails. dont know much about the clutching, but i can say his track has more weight. i dont know if that would be a reason for some of the difference.
Check your track and cut it. It would take years to wear in, and then it is dragging on the guards so your just wearing your guards down.
Though I think from your gearing description, that's a big issue to start with. Also when trimming the track, sometimes the tunnel guards are different offset or width than the front guards. Trim so they both dont hit
