So who all of the WC guys are left after the site switchover?

but im a question asker, not a question answerer

 

[joshkoltes]

symtoms?

so this 1200 at idle has two cyl (mag, pto) with no fire. only running on center. until revved up to 3500, then the two dead ones come alive and jump to 5000 rpm.
checked spark before start, all spark when not running with a basic spark check.
running xcr ignition programmed with TPS.
any thoughts

 

[joshkoltes]

possible

quite possibly found the problem, flywheel must have ate somthing through the belt hole. destroyed some magnet causing low voltage maby? anybody have a spare xcr flywheel?

I get to put mine on a load cell dyno on the 12th then go to the hill drags the next day. I can't wait to get everything out of my race setup then show it off.

Stil here

I'm still around. 3 seasons at sea level, pretty much got it figured out with lots of help from Brad and some dyno time.

I'm still playing with getting my 1050 running the way I want. However, it was riding season and it isn't important enough to stop riding to work on it. I'm going on revision 4 with the pipe. I wanted to keep everything under a stock hood, so I've been building a single pipe for it. I'm making progress, but my snow went away before I could make any more changes. I need to gain another 500-700RPM, but I'm at least headed the right way. Biggest problem I'm running into is loading the motor hard enough to get the pipe heated up (and traction, of course). I have to admit I'm a little concerned about the new arrangements as well - only "premium" members will have access to all of this. It shuts off a lot of the traffic....

Rocket, what kind of a chassis do you have yours in? Just curious cause you mentioned you are going with a single pipe.

I got one season on mine at 2000 feet, not alot of miles though. Did lots of tuning and playing around with it. Never really took it for a real ride, just playing around in the fields by the shop. But man does it rip and its not even tuned in, need to get about another 200-400rpm on top and I am still rich on top with the powerjets. I did have one mishap though, last time i got to play around with it before the snow left I blew a belt and took out the clutch guard, bellypan and PTO pipe. Probably going to have to have the pipe sent out to get fixed, its got a very long and deep dent in the head pipe section.

Got some improvements to do the sled over all, going to try a new track to get it to hook up better, I got an old Polaris Camo RMK track and all it wants to do is fold over under power, I might dig into my M10 also and see what I can do there.

When it comes down to it I love the motor, like I said it flat out rips and there is still some more left to gain. Cant wait for next winter so I can ride it again!

I've got an older Pro-X chassis, so the tall shock towers and bracing eat up a lot of room. That and I'd never get away with anything with running any triple pipes without a cannister silencer of some sort - way too much noise. Another reason is that I had the thought in mind about eventually getting this motor into a "consumer" IQ chassis and there would be no way possible to get triple pipes under that hood - but what I've got would fit. I know it will cost me some HP, but I've hear rumors from a couple old-timers that there was a shop working on an aftermarket single for the old 650 triples back in the day and they claim it was close to what could be had with a set of triple pipes. Problem is that nobody wanted "close", they wanted "more" and "loud", so it never went anywhere. I'm still digging to see if I can find any info on what they were doing or if it was simply optimizing the pipe. Its been an "interesting" project if nothing else. I've modified pipes for twins before, but the triple is tough because there is only a small window to get the pulses into - the cylinders are almost firing on top of each other.

 

[the_hog]

Very interested to see how the single pipe works out for you. Keep us updated. Also keep us updated on putting it into a consumer IQ chassis.

just keepin a good thread near the top and if anyone is looking, i am selling my 1200 wc motor and pipes in the swapmeet engine section.

i have a 1200 that i had run about 300 miles and had a pto end bearing failure,i was wondering if their is a mod that people are doing to allow more oil on the pto end bearings.i was at the dealer the other day and the tech was showing me a broken crank from a 800 dragon and on the pto end teir is a wide single bearing on the crank,i didnt measure the bearing but it looked close,does anybody know if it might work on a 1200?these motors are awesome i have a ub 1500 and the 1200.sold a 1350 which was as strong as the 1500 i have now.i run the 1500 in a proline drag chassis and beat up on the turbos all the time hahaha

I saw an "Fastrax" watercraft with an custom singlepipe, i am sure that it works good because it where in an race of some sort.

I have seen a few "indyspecialty" cranks with the wide bearing, they seem to have the stuff worked out really good!

I've had some good listening "conversations" with Dan and he does not do the widebearing cranks anymore. He didn't think that was the proper solution to those things. I think he did for a while but he's learned how to do cranks without that wide bearing.

What Dan is preaching is cases!! The quality control on the cases from Poo are to bad, and when you run a loose case/crank fit on a twin it messes up things fast.

The triple setup on these engines changes harmonics and vibrations to the better, so if you get your cases and crank set up good then no probs.

Call Dan for details and have him setup your stuff.

1200 wc pipes

what pipes has everyone tried on the 1200wc motors for edge chassis?Which make the most horsepower?Best overall quality?

 

[joshkoltes]

mounts

i need new motor mounts 90 durometors. where do i find them? high performance has discontinued them
never mind found them from wahl bros.
