    Leak down test or pressure test on the cooling system? What size domes, who did the porting... edges chamfered?
  2. Atomic Monkey
    Was there a reason it was apart such as siezing a piston?

    How about chopping a stocker down since I have a few, and then weld up a roundhouse to it?

    I forget what they were... and they're still stacked up in storage. They look exactly like the ones in the pics from the OP. I got holeshots for the fronts, and they're great! Going to see how the rears hookup with all new studs, and then make a decision on whether or not to go to a larger tire. I don't mind using my weight to get better traction, just trying to stay away from the flyswatter effect of having too much

    They were only 1/2". Still lost screws going to 1 1/4" screws, so I made play tires out of 'em and pounded 1 1/2" Kanadian Ice Screws into them because they have a larger shank.

    I got some plastics that were a little chewed up on the front fenders... fixed that with a sawzall!

    Had the same setup for the rears last winter b4 I melted down because of a leaky head gasket. Got them when I bought a parts lot off CL. Did a lot of time sitting on the rear fender trying to hook up, and chucked almost every stud the first time out.

    I've always liked ProCircuits over FMF! I've had them on my CR125R, my WR500, and now on my Banshee. Everytime they out perform simular setups with FMF's. I think there's a dyno sheet around with ProCircuits on a 421, and the curve still looks great on the bigger displacement engine. Anyway, the only upgrade I would consider so far is the CPI. Good luck with you build!

    That makes it simple then. If you want a hand, let me know. I'll pull the cover and get some pics for you, it should be the same kind of winding setup on the stators.

    I've got the Racetech 200w dual output. The extra output is a white wire on mine. You're right about needing another regulator. Do you remember the exact model stator you have? I floated the ground on one side of my stator, and when I was looking for a regulator/rectifier, I noticed Evan had 200w single output stators available.

    Lol, getting ready for next months trip? I was talking to my buddy up in Pembine, said the trails were better to the west. But if we go north, I'm bringing the bike along. And I don't think the ac/dc matters on heated grips, just got to watch the wattage. What stator did you have?

    I made nipples that fit in the boots where the crossover tube goes in. 1/2" copper pipe fits well. Then I use a Motion Pro sync gauge. When I first used the sync gauge on the banshee, I ended up with unequal turns on the air screws to get the idle mix right. I've since then changed pilots, and found the whoever installed the originals left a burr that obstructed flow. So I'd say the sync tool would also be good for diagnosing certain idle and off idle issues as well.

    I had a great time, and the cabin was awesome! That was some of the best trail riding I've ever done!

    Finally got to ride the trails, and get a good run in over the weekend. Still needs some tuning done, and the domes worked a little. Overall I'm happy with how everything turned out. The bottom-end didn't improve much, but mid to high has improved greatly! Especially the transition. It used to hit really hard when the pipes came on, but now its a lot smoother. I haven't kept the throttle pinned for very long, I just know it tops out a lot faster... even after dropping a tooth in the rear. So for now I'm going to address the domes to correct the squish and compression. After that, put the 34mm carbs on and get'em jetted. The only thing I might do after testing the larger carbs is widen the exhaust a little more. But so far there doesn't seem to be a need for it. I did manage to get tossed twice. First time I slid off the trail and hit a rock, the 2nd time was on asphalt sliding sideways and it bit in.

    Just took went out.. leaving tomarrow for "up north" , I'm saying there's a definate improvement from what I had before!
  17. Atomic Monkey
    Actually the numbers I got weren't far off of what I had with the short rod 4mil and Vito's super stock pistons with the stock cylinders. Those were 192/125/33.5. The reasons for doing any changes with the new setup is only because I had certain #s to get. But as of right now everything is put together, I plan to start it tomarrow. The domes I got, put the compression at 120psi and 0.060 squish with a 20cc chamber. I'd like to see a narrower squish, and possibly higher comp, but will be safe to ride... leaving on a trip thursday

    I'm not really impressed with those numbers either. Not that I know much about them, but I know what I was shooting for. Thinking about trying a thinner base gasket, or even taking a little off the bottom of the cylinder. That's about all I can think of to drop those #s a little, and to raise the exhaust enough to get a better blowdown #. Like I said, the transfer heights are untouched, and the exhaust was moved up and that's how I ended up at 194. But at least I didn't over-do it right off the bat, and have room to work with things.

    The Banshee cylinders that I've been working on
  20. Atomic Monkey
    Got the #s... 194 exhaust, 130 transfers, 32 blowdown. That's with the transfer heights untouched, and the exhaust having been raised.
  21. Atomic Monkey
    Got the gasket match done, and case assembled tonight. Just waiting on the cylinders now.

    Here's a shot at the bottom of th WR transfers

    Just watched that CR video! I love that shit! Had my WR500 out yesterday... first time this year, started 3rd kick... and is effin scary! Can't tell if its spinning or slipping the clutch... but it's next in line for porting and a bigger carb!

    I'm stoked to get the cylinders back! Aside from removing material to increase and direct flow... I took some advice and am curious to see where the timings end up. There's about 1 1/2 weeks til the 'shee needs to be trail ready, so I hope it's close enough! Finally decided to go through and figure out where I started from, mostly to have a baseline because I liked how the previous setup responded. 192 / 125 / 33.5. With 4mil 110 rod, stock port, spacer plate, and Vito's Superstock Pistons.
  25. Atomic Monkey
    Maybe its just the case I have, but to gasket match (I'm using a cub gasket) put the line for removing material on the outside wall, and wouldn't allow for the radius I wanted.
