    zx 2 revalve

    Just got back from the UP and my zx2 was acting like a pogo stick. This is in my 06 Vector Gt. Had the front shocks freshened by Pioneer before this winter. The zx2 shocks were redone by ad bovin approx 2800 miles ago. This sled has the two stage shock springs. I have them set on the 3rd...

    ZX2 Guys

    I'm going to do a suspension swap this fall and am trying to decide between a ZX2 and a ProX. ahicks has been very helpful and I think the ProX might actually be easier than the ZX2, not only cheaper. Ad Boivin has a special going until July 15th. Basically you get the mounting kit for...

    Skid Swap and Stretch

    I'm currently running a 05 RX1 with Bender rear mount turbo, 121 mono with Pioneer 6.5 spring and revalve. Much, much better than stock. I'm considering an upgrade. Leaning towards a ZX2, if I stay 121. Have been reading swap posts for several days and it seems that the guys who stretched the...

    Malpassi Fuel Pressure Regulator

    Anyone know where to get a new spring for this regulator? This is the third time I've had to turn the adjustment screw to maintain my 5 psi at idle. Last season I took it apart and there wasn't any dirt in lines or regulator and also put new filters in tank. Each time I turn the screw...

    Octane vs Air/Fuel Readings

    Since stock RX1's run fine on 87 octane, does running high octane gas show a lean reading on the a/f guage. I ended up running 20 pilots at 2 turns last year to keep my a/f readings in the 14.3 to 15.3 range depending on weather conditions and elevation. At home I'm just under 1000ft and...

    Help- clutching for the UP

    I'll be going to Newberry on the 18th for a week. I'm presently running a CPR clutch kit I got from Matt last year. Only thing different is I'm running the white spring at 60 instead of the silver at 100. y/s/y primary, heavy hitters with 3/4" allen in heel, 7/16 steel bolt in #2 and #3...

    Leaner than ever in midrange

    First off, I have to say the sled feels great. No bogs, hesitation, or any signs of problems. If I did not have an A/F guage, i would think it was fine. It takes throttle anywhere, from a dead stop, from any speed, and feels crisp and clean. Filled it with 93 pump gas, and set the boost to...

    Are the VM28/486 the correct jets for a 05 RX-1? Do you have the 20's part # 42-6175 and the 22.5's, part # 42-6178 in stock. Thanks , John

    Wide Band Air/Fuel Sensor

    Anyone run a wide band air/fuel guage last season? I'm wondering about the life expectancy of the Bosch sensor. I just installed a Dyno Tune Wide Band LC-1 on my sled and the sensor lasted about 20 minutes. I ran the sled twice on the stand to make sure all the guages are working properly...

    Ready to junk this thing

    Stock jets, needles, fuel screws set 2 turns off seat. Nice idle, but continously popping between 4500-7000RPM. Moved fuel srews to 2.5 turns out. As soon as I started it, I could tell it was not right. Sychronized the carbs and they were right on. I figured I would put up with some burbbling...

    Help: Still popping when low boost or no boost

    I got the sticking slide fixed, set floats @ 17mm and cleaned all the jets etc. Sled is great under boost. Above 7000RPM the thing pulls great. At 10-25 MPH the sled pops, non stop. Taped the pitot jet closed and removed jet all together and no difference. I guess the pitot jet doesn't do...

    Need Help Dialing in Bender Stage 2

    Sled has terrible bubbling and gurgling between 4500-6000RPM when not on boost. Runs great when accelerating, but cracking when trying to cruise at this RPM. Was at 2700ft and 8 degrees F, today. Sled accelerates crisp and clean and builds boost well. Ran pitot jets from 100 thru 700 and it...

    Warning Light

    Took the sled up to the club house yesterday to try and dial in jetting etc. Put about 10 miles on in the fields around the parking lot. Triangular warning light would come on for 25-30 seconds and then go out for a minute or two then back on for 25-30 seconds. Did not blink and no other...

    Battery Box Modification

    Did anyone try to modify the battery box yet? The wires on the right side run over the top of the cross bar and my metal oil lines from the rear turbo, run over the top of the bar on the left side. So getting the cross bar out is near impossible without disconnecting the oil lines. What I...

    Installing Bender Stage 2

    I know that a lot of the guys are using hair spray to help secure the air box to the carbs. Is it necesary to use anything on the silicone couplers on the charge tube and turbo? Or does the silicone work well alone? Thanks for the help.

    Clutch center to center

    Have the 05 apart to put the turbo on and while checking clutch alignment the Maxximum center to center tool shows the distance at least 1/8 inch short. Is there that much forward movement to adjust on the motor mounts?Thanks

    Fourth Rear Wheel kit on 05 Mono Shock

    When you install the 4th rear wheel kit from Yamaha, you have to modify the 2 small spacers in the kit. Take 2mm off each of the spacers or use one of the spacers that was on the sled and use one from the kit with the 2mm removed. If you don't it spreads the rear rails and the 2 inside wheels...
