    Nothing too newsworthy about that.

    But I'll be sure to post my review here. I've been impressed for a while with their innovations. So I'm confident that this'll be worth it.

    Now I gotta wait til it arrives. Won't be easy.

    Ever since I saw it on their site I've been wanting one, no chance of me getting it this month. Got the jack shaft this month and love it "that's over my budget this month", and while it helps a lot with top/low end. I'm still looking for more out of my bike, mostly low end but I figure they mostly go hand and hand. I've already hit 40, I really don't need to go faster then that, but more power on take off and climbing hills would be nice.

    Let us know how it goes, really interested to see how well the couplers seal and if any other fudging is required with adjustment pieces it has.

    Yours shipped out. Let us know how the installation goes and how the perf gains feel (or maybe are measured vs. stock)

    We are interested in feedback on the packaging as well. First time we actually had to buy boxes.

    I'll definitely let you know. And since you mention it, I'll make note of the packaging as well.

    I appreciate the quick shipping. I imagine I'll have it by the weekend. That's cool.

    These days I'm a bit on the busy side. So I may not have the bike up and running this weekend. But within a couple of weeks is surely do-able.

    Thinking about it a bit more, I only have one regret; that I didn't also order the mounting/engine cover hardware kit.

    I was thinking of it. But I also thought, "well, I do gotta be careful about spending...etc".

    What a dummy! It only cost $10.00. Now, when I'm doing the conversion, I'm probably going to have to make a trip and spend an hour looking up all that hardware.

    Just thought I'd throw it out; if you're ordering accessories you might as well get the incidental stuff like this that you're going to need and be done with it.

    Here are some performance figures from our testers. They averaged a little over 3 mph more in top end. In acceleration runs from 10 to 25 mph a decrease in time from 15 to 12 seconds. That is a serious gain in acceleration. Again these are averages from our 3 testers and your results may vary.

    I'm actually a bit more interested in performance at low engine speed.

    I want to just putt along at 10 mph or so. Do you think I can expect smoother performance at that sort of speed?

    While I'm at it; do you guys sell a larger drive sprocket? (50 tooth or above)

    I just did it with the shift kit, spent 300 for the kit, upgraded freewheel and something else, but drew the line at an extra $10 for the freewheel removal tool and oil. And already have over an hour into finding something that will work. :dunce:

    Thanks, Shadeslay.
    It's kinda nice to know that I'm not the only one to make such a dumb mistake.

    We'll get through it, of course. And we'll also know better next time. good luck.

    I just got mine in the mail today. Install will be complete and ready to go on my first test ride tomororow afternoon.

    This will be a test of my following setup:
    Schwinn Searcher with 7 speed MEGAR derailleur (34 tooth first gear is a monster hill crawler)

    HI ALTITUDE operations from 6600 to 14110 at the top of Pikes Peak. Yes, I'm considering setting up my own death race to the clouds up Pikes Peak.

    High compression head has dramatically increased perforamnce and the tuned pipe should get me to my desired top speed of 40-45mph...its close and almost there with the 5% nitromethane fuel I'm currently blending into my fuel mix at a secret ratio to supercharge my mixture. Nothing better than the pop of nitro cooking off when it ignites.

    SBP Tuned Pipe Kit will be tested ASAP with GPS on board with accelerometers to record acceleration improvements and top speed improvements over varied conditions as mild/steep hills, straightaways,etcetc..

    If the SBP tuned pipe can give me the same improvement in performance as the high compression head, then I will be in HEAVEN.

    My dream bike is almost here.....auto clutch, pull start/pedal start, fast shiftable gears.....YIPPEEEEEEEEEEEE

    I received the kit. The packaging was just fine.

    I haven't installed it yet. I'm hoping for tomorrow. I'll post my results.

    I broke down and ordered one, seeing how fast they are running out of stock I figured I should while they have them. Just went to check the specs and it looks like they sold out again. Hoping to have it sometime next week. Now comes the waiting. :sweatdrop:

    Well just got mine today, installed and omg I love it. Second best upgrade I've done yet, jack shaft is still the best. But I have a very noticeable increase in low end torque and a small increase in high end "2 mph". I only trimmed about a 1/2" from the assembly. Don't get me wrong I love the added performance, but I like sound even more. It's slightly louder then then an unmodified exhaust, but not too much. Sounds much more like a motorcycle now, instead of a lawn mower.

    I did need to take my kick stand off, just wouldn't fit with the pipe, so I'll look into one that attaches to the rear of the bike.

    I've got mine installed and my results are similar to yours. Though I only got in a short ride yesterday before the rain came. More testing today.

    I think I'll post a more complete review in a new thread for the sake of those who want to see reviews before deciding whether to buy or not.
