  1. Came with a 2018 ZR8000 I bought.  Was not on sled when I got it but seems complete.  One pic from the sled was listed with it on.  I believe the Cat PN is 7639-358.  Includes brand new set of footrests. Figured I'd throw it up here before ebay to avoid packing/shipping.  Cat retail is about $700.  Throw out an offer.  I am an hour north of Green Bay and am willing to drive a little.

    I knew Speedwerx was a Precision reseller, but I didn’t realize that a “Speedwerx” tune was actually a rebranded Precision tune (if that’s what you meant).

    To jdels point about slow speeds with family, my experience with the Riot is that the 8000 is not happy at all in the “safe speed” RPM range.  I went with a Speedwerx tune and clutch kit before Haydays to see if I could fix that.  I have no experience with the tune or clutch kit yet.

    As mentioned, I think people with concerns should actually call a vendor to talk about it.  Sooner is better to avoid downtime when the snow flies.

    Couple calls on Monday for sure.  Speedwerks is offering a '21 'stock' tune now.  Will be interesting to see if they claim it as their own.  If a reflash and some weights can offer some margin in the 'safe speed' range that seems worth it to me.  Thanks for the real world assessment, appreciate it.

  3. My two biggest concerns are reliability and longevity.  I do a fair amount of riding with my two younger kids so there is time spent in the lower RPM ranges.  Hard to justify spending the money having not even ridden the thing yet but I sure as hell do not want to be sending out ECU after the season starts.  Precision or Speedwerks seem to be the two options, so looking for some real world testimonial to help make the choice.  The good ole F7 (bought new) has over 10,000 miles on the original top end and still showed 126/128 compression at the start of last year.  Not sure if its reasonable to expect that out of the C-Tech but I'd sure like to do the things to give it a fighting chance.  Cylinders and pistons look good through the y-pipe.  2200 miles on it, 2018 ZR8000RR.  Thanks for the input.

    On my 19, it has a spot in the 5000 tom range when maintaining a 10-15 mph speed, when the engine is not fully up to temp (exhaust temp) where it would want to huck a buck a little.  It was annoying because my sled is for off trail and I'd do a fair amount of that.  I think for a trail sled I would never encounter that specific operating condition when on trail.

    I also noticed after I installed heavier weights in clutch, I'd almost never encounter the problem.  Not because it's a clutch issue but because it loaded the motor down more and at those speeds it's at a little higher load and a lower rpm, maybe 4500 now, and it's at a place in the mapping where it's more happy.  Once or twice I noticed it's still kind of there but it's 95% better/eliminated.

    I have thought about adjusting the TPS.  I would do this carefully and take measurements before adjusting so I could always put it back to stock.  But my thinking was if it thinks the throttle is open a little more, it will give a little more fuel, and solve that problem, it would only take a little.  I know some efi systems learn the base idle TPS voltage every time you start the engine so in that case, in simple theory, it maybe wouldn't change, I'm not sure if the cat efi system is like that and I'll probably try it at some point this winter regardless, just to see.  They say if you tamper with tps it voids warranty but my sled is out of warranty.  It is something free to try and an alternative to $500 for a tune, which I'm not going to do anyway.

    I'll post about it when I try it.  I think after the weight change the only time I now have noticed it is very early in warm up riding, and even then it's been much less pronounced.

    Just a weight change?  How heavy?

  5. Never rode this one either so its tough to justify.  I do ride with my two younger kids alot so not all my miles are spent in the upper RPM ranges.  That fact alone has me considering just doing it.  Thanks for the response hopefully someone will chime in and give us both some insight.

  6. Just picked up a 2018 ZR8000.  Is the fuel map as bad as what some online stuff would suggest?  Anyone have experience with aftermarket flash, the Speedwerks tune is where I'm leaning.  By the looks of the can its been pretty hot so it seems there is definitely a lean spot there somewhere.  2200 miles on it, cylinders and pistons look good through the Y-pipe and I'd like to keep it that way.  Thanks.

    I don’t want 72s because two many wires to one spot, I have 20 of the 18s and one 36, the 18 are easy to set for small effects at different spots or shells apart from the main site, helps at weddings too when you have multiple sites for one show.

    I use the scripting software from cobra, you can’t ask for better. Customer service.

     

    my crews want 36s for 4th of July week, they’ll probably get them too. 

    Yeah, no way on 72's for onboard cues.  All slats here.  I prewire everything so it works well for my typical set ups.  If you every have a show within striking distance of northern WI and need an extra body let me know!  Couldn't agree more on Cobras customer service.  World Class.

    I use cobra too , need 2 more 36 and 3 more 18s to get through memorial weekend.

    Same here, started with a 72 and a pair of 18's using slats for everything.  All Private shows for me but I wish I would have started with a pair of 72's.  Do you use any scripting software?

    Nice!  

    Is your shop Plumbed? 

    Ok, my interrogation is almost over :) I'm just really interested because Pex has been my go to but only experience I have with it are shops with refrigerated air dryers.
    What do you run for filters? 

     

    I'm only running air tools and blowguns, I count on the inlet filter on the compressor.  Shop is plumbed with 5 outlets and an auxiliary tank.  I'd guess maybe 80 feet total.

    Where are you located? Do you have moisture issues? 
    that is my biggest fear about Pex.  

    Also, what line pressure are you running? 
     

    Southern most tip of the UP.  I have an older 30 gallon Craftsman compressor with a second 30 gallon tank.  All lines are pitched towards tanks and I blow them off monthly.  No moisture issues.  Shop is air conditioned in summer and I'm just a one man blowhard wrenching on my own shit.  Air is always on at a max pressure of about 135psi.  

     

  11. Not licensed but put on a couple big shows every year.  Regularly toy with the idea of a Type 54 but just never seem to pursue.  Last years show on the 4th was 108 cues, all e-fire.  Finally made the leap to COBRA this year, huge upgrade from the Chinese firing systems.  Ben used to blow off quite a bunch of stuff if I recall. Here is the set from last year, curvature is due to the pano photo.  Decent mix of consumer and 1.4Pro cakes and 162 shells.  Also had 4 wheels and 4 500 gram fountains.  Product availability could make this year interesting.
