I know it has been a while, but did you get things resolved and what was the problem?

I have never used a test light for that purpose on these motors, so unsure if there would be enough current in the pulse to power the light so you could see it. What box are you using (12 pin ) or...

Chuck,
Have you pulled the plugs to check spark actually occurs. I had a ton of issues with the boxes before I realized the power on function is critical for the MPEM and it can not get the full...

See your PM, not sure if anyone got back to you on this.

Finally finished 2 sessions this past weekend, but not with out issues Saturday. Went out first session and was happy until lap 9 or so and then it sounded like a grenade went off in the engine...

I now have a running car again ;). After Portland, I towed up to the Majors in Washington over Memorial day, continued with fuel delivery problems (Oil was plugging up the pulse side of the fuel...

Rebel Gears has a lot of chain sprockets, good place to start. The pucks are rubber, they can be purchased or you can source the rubber and make your own, McMaster Carr has some rubber sheets that I...

Hi Brandon, there are many options and it is highly dependent on the chassis. Most folks that support the particular chassis will be able to supply your parts. May get some better info if you lay...

Terrible start my season last week end. Lost a motor, looks like carb jetting most likely, I may have missed the symptoms due to new data system that was not 100% functional. My new motor lasted...

I only found this after I resolved my issue, but it was posted in 2015 at the other site and it did not say why the relay was important. I had read it but thought because they were using a sled...

That is a correct statement, but if you like to have an integrated system and a battery that gets charged from the voltage regulator, and you have a 2003 box with a 12 pin connector (not a direct...

Finally resolved this this weekend. Turns out the BRP relay is a critical purpose in the circuit. I was trying to power up the MPEM straight from the battery, and that does not work for some...

So the issue has not yet been resolved, if any body has a picture of their connections or diagram of how they wired up this type of MPEM, let me know. It is a 12 pin 2003/204 360w type MPEM. I am...

Thanks, I currently have it disconnected completely since I started having issues.

Unfortunately I have still not been able to get a spark and start my motor, despite new box, just programmed, New coil, new triggers, new spark plug and again going thru the wiring diagram, try...

Still no go, when pin 1 is powered , pin 2 see's 12v anyway. The saga will continue, but I do not have any more options for this MPEM. I ordered another off Ebay and will send in for programing and...

I went wire by wire thru the diagram instead of coping what I got and looks like pin 1 and Pin 12 need 12v, not pin 2. So back to test that today.

Yes, that is a screen shot of that diagram, I copied the harness I got from Jeremy, so pin outs should be correct, according to the drawing Pin 3 I thought was the circuit ground and Pin 6 the kill...

I got all my new motor hooked up and wired up but can not get spark to the plugs. I only have 1 box of this style so looking for any recommendations to test the MPEM box. I got the motor and box...

i Used to pick it up off the red wire from the Stater tri-plug that went to the CDI box.I think (/6) in the software to get the correct RPM. If you use a 18 gauge wire, you can stick into the plug...

I really only started the thread to get the thought process going, not start a blame game. Maybe 10 minutes each would be a better option or just line up by time instead of class.

I see they posted the schedule for the runoffs. Looks like FF/F500 will be together in all the Q sessions. Too bad they could not break it out for at least 1 of the 3 sessions. F500 is near the end...

I have thick seat bottom that I plan to cut a couple pockets in to slip in some lead dive weights. I have in the past slipped some ankle weights jammed between the front of my lower seat cushion and...

I use the Hans 30 deg. If I was in the market for a new I would look at the hybrid or the nexgen, it does not have the tall back.

Thanks all, I ordered them straight from Cometic, 3.52 each. Should be delivered in a couple weeks.

Thanks all,
Mike is working on a motor for me so I may wait until he gets one and include them.

Where is the best place to get the restrictors from.

yes. I apply a small amount of preload so at full droop, the cone is still applying some pressure to the rubber puck. As the suspension travels up, the cone deforms the puck, this compression then...

I will be rebuilding my canisters this weekend, I will take some photos to show the KBS style.

All,
Checking in to see if what others may be willing share about Puck material. I normally run natural Gum Rubber in the rear (40 durometer) and a black (can't remember the type of rubber) in the...

Thanks for the input, I think track time is going to be my limiting issue next season, so to develop a car AND driver does not give me a warm fuzzy.:(:duct:. I see that as a roll of TP, not duct...

Thanks Clint, I had some questions Answered about this from a someone else that helped me decide. Maybe next year I will have more opportunity to jump into the 600 MC world, this year just not...

I am trying to find info on the Red devil Conversion that Rick Eskola had. 2002 with Yamaha motor and belt drive setup instead of chain. I am set to decide this weekend weather I grab this car from...

That sounds good, when you plan to come to Portland? The temperature is pretty high for that cool outdoor temp, a couple years ago I updated my Radiators on my KBS to a nice (expensive) 2 row custom...

Complicated question, over the years I have used and quit using many sources. Best option is to Google a bunch and find a company that sounds good. They may not be there in a couple years.

Ebay item if you have the bracket for the starter
New Starter For Polaris Snowmobile Replaces OEM 2410748- "4170006 5768"

Way to inspire people Clint! I met you at the 2014 runoffs, and you had nothing nice to say about the other MC competitors, so I do not know why this is a surprise. This is pretty insulting to...

Wayne,
Bernoulli's principle may be applicable in this case.

In a quick list, you will need the following:
1) Clutch with ring gear-Most expensive part as you can not just attach a ring gear to any primary clutch
2) Bracket to attach starter to motor
3)...

Most have probably built there own sheet based on Data collected. You would be in the area of 260 ish to 300 ish depending on the weather and engine condition for the main jet and also depending on...

I do not follow ICSCC much, but did race this summer in the Doernbecher Dash for the first time. Not sure if I will run my F500 much in this club due to the grouping. I would really like to run...
