    Engine going rich overnight.

    I just thought of something and it just dawned on me, you are the fella with the big turbo and advanced tuning that was having boost issues. Did you save your changes in the app to default when it was running correctly? Is it possible that the fine tuning in fuel percentages in the app has...

    Belt problem critique please

    What offset are you running? Setup to float or bolted solid secondary? What is the EPI spring set at? Helix? Belt? Primary weights and tune? Offset? There can be so many reasons why. Wrong offset, clutch sticking outward if it floats and not lining up, poor clutching, oil on belt, but looking...

    You need to see this!!!

    Is the 1049 shaft with the reluctor wheel on it?

    Engine going rich overnight.

    When you key on the sled before starting, what is your boost reading? Looking at log above idling it seems like its .1 is that accurate or has it changed with the issue? Log above appears to look fine with A/F. Can you show a log with it acting up? What tune? TD or Hurricane? I can have a look...

    Grinding mystery ???!!

    Its going t o take some miles for the new track to stretch and its more prone to being noisy when new and short. Also it appears the track is running off to the right side of the drivers making even more noise hitting on the left side of the drivers. Trust me, that noise is normal and it's not...

    Grinding mystery ???!!

    It's all totally normal. You have to realize the track is trying to out accelerate the drive sprocket cogs. There is about .010" of "lead" built into the drive sprocket lugs by design, so when under power, the cogs engage on top side without ratcheting. So while turning by hand, the track is...

    Midwest snow report

    We are looking at brown ground. Local news forecaster is calling it "the winter that never was" already. He's saying Feb is slated for well above average temps so I don't have much if any hope of turning a track here. Close to 50F temps in the forecast. Nightime lows above freezing.....

    Holy helium filled Sidewinder Batman! Yes boy Winder (see what I did there), I filled the remainder of the fuel tank and air shocks with helium.....

    1,000ft

    I'm seeing plenty of 600 Catalyst now advertised for low to mid $13K, but agree they are well overpriced for what it must cost them. Yamaha exiting the market is going to drive pricing higher along with less competition to bring good stuff to market. When you look at what Side by Side MSRP's...

    Non-Adjustable Fuel Pressure Regulator

    If you dont want to mess with adjustable reg then yes, it's the answer for the big pumps. Remember when the 17 came out and some guys had poor mileage? The fuel elbow was too small and guys were drilling them out or switching to the larger elbow to fix this. Same thing.... The stock fuel...

    Non-Adjustable Fuel Pressure Regulator

    Well if I assume he has closed loop, not sure if he does, but if he does, and the stock regulator is used or say the return line is pinched or too small, the Close loop cant overcome the high fuel pressure the mileage will go in the toilet, but it also should be noticeable that its really rich...

    3 wheel offset axle

    Yes stock big axle, 1" I believe is what it is. They are the BIG bearings that last and last forever. So the Catalyst has the same setup as these problematic sleds did...... Man you'd think that the engineers would stick a nut on the end the axle assembly tightening down on a shoulder on the...

    Non-Adjustable Fuel Pressure Regulator

    I highly doubt the O2 sensor is at fault, in fact I would guarantee it's the hi-flow fuel pump making for a fuel thirsty machine. Depending on the size of the pump installed, It a fact that the stock fuel regulator can't handle the flow, the pressure is rising and is tanking the fuel mileage. So...

    Non-Adjustable Fuel Pressure Regulator

    Adjustable reg allows for enriching or leaning of the A/F of the base tune, non adjustable does not. Has nothing to do with power levels.

    Non-Adjustable Fuel Pressure Regulator

    The Hurricane big regulator is capable of more flow with their big pump, if you tried to use the stock regulator it would over pressurize with their big pump and have too much fuel pressure. Big pump allows for consistent fuel pressure at high HP ratings.

    3 wheel offset axle

    I'm using the Hurricane stock 8" size 4th wheel kit with their billet alum. spacers & mounts, I like the fact they are using the good old style Made in USA - PPD HD 8" wheels with the big bearings in them. I know these PPD's will hold up extremely well. I thought PPD was made in Canada a while...

    2025 SRX color

    Lots of rebates from the OEM's now too. Its getting real again with the poor winter. I have a 23 here that came late last year I haven't ridden this season, and from the looks of it I wont, I put 60 miles on it this last spring. The local news said Feb looks to be much warmer than average...

    AEM vs ECU Wideband

    Installed it on my 17 and it worked great, now using it on my 23 and working fine also. Cut two wires as I recall from the original plug and installed them on the one I bought from Amazon on the same color wires and plugged it in. Worked just as it was supposed to. Take note of the wire colors...

    Electronic waste gate TD

    When you get up over 100 on the multiplier it doesn't do much I'm told. The boost slider is on your app with the multiplier, depending on where its set for the tune, say you have a tune set for 20 lbs, but have it at -2 it would boost at say 18 lbs. Perhaps you have the slider set at a negative?

    Electronic waste gate TD

    What's the crack pressure set at? We're do you have boost slider set? Is it set at a negative? It looks like you have the WDV multiplier set at 120, not that its making a difference on the low boost, but I thought at 100 it was all done and all in at 95-100...
