    The rear mount of the guide has an offset which should be flipped for rear sprockets bigger than 45. Just loosen the rear bolt and press out the offset nut on the rear and flip it 180 degrees.

    Beat me too it :deal

    It was done before I bought the bike with 73 miles on the clock :evil

    It still rides great on the pavement. Slightly buzzier than the stock gearing, but I can still sit at 65+ all day and still feel my fingers after 150 miles. Where this gearing really shines is on tight trails - where my 520 really stood out, I can now ride my 690 with loads of confidence. I also have the Leo handlebar switch, which really enables this gearing to suit my riding style perfectly.

    I rode some nasty single track last weekend on the 690, and was able to ride the same trail on my 250 smoker for comparison. I gotta say the I enjoyed both bikes for different reasons - but found them both very capable. The only hinderance I had was the weight of the 690 over the 250. Both bikes were great tractors

    Is there enough adjustment available to run the stock chain length with a 15/48 combo?

    It might be long enough, but I replaced the chain with a DID that was 2 links longer. I know that with my +2 chain that I can run 14/48, 15/48, 16/48. I have a new 50 mounted up on my spare sprocket carrier to try 14/50... the chain will still work with that combo but might not work with 15/50 and will not work with 16/50 (not that I'd run those combo's.)

    What was the total chain length you used? 120 rather than 118?

    I'm almost positive that I used 118 links, as I always buy a 120 and cut the excess off to keep as a trail spare.

    I verified yesterday that the chain I have on (2 links longer than stock) works with 15/50. In theory, that would lead me to believe that 15/48 would work on the stock chain (2 less teeth, 2 less links.)

    I did a little running around with 14/50 last night and I can now stand the bike up in fourth gear up to ~70mph but find the rev limiter in sixth somewhere around 90 (on a closed course, of course! :lol3)

    Starting to feel like an MX bike having to shift so fast! I can be in sixth without feeling like it's gonna stall by 45mph, 70mph is roughly 6000rpm now.

    Edit: It was eating me up not knowing how long the chain was so I went to the garage and counted 116links, so stock was 114.

    Yea, I counted too -- 114 links. Your estimate of 70 being 6K rpm is actually rather accurate:

    690 14/50 gearing.
