    You can move one mount. Several people have cut the "ears" off the top mount, flipped them around, and then welded them back on. This moves the plate enough so that the extra length isn't an issue. If you want to do this, please be careful - the top shock mount is the ONLY thing that holds the back of the bike up - if your weld is not solid, it could fail at speed and cause a pretty major accident.

    Will this shock just bolt on and provide a stiffer rider than stock?

    Or this one?

    First one - no - need spring weight of at least 800, 900, or 1000 lbs. Second one yes, however, may need extra washers 5 for top and 5 for bottom.

    Because the frame mounts are wider than the mounts on the shock?

    Yes - but only by a couple of washers - the initial strength is fine in the shock - know of several with it and have two myself - http://www.ebay.com/itm/282143020833...%3AMEBIDX%3AIT

    So I just installed a CBR shock, and I'm a dumbass and didn't measure the bike's height before the mod. The factory seat height is 27.5" and Jetlee let me know that's in the middle of the rider's seat (so about 1/4 the way back). Because the bike tips at such an angle I'm looking for a secondary data point. Does anyone with a stock suspensioned blast have a measurement from the lowest point on the seat to the ground? Thanks!

    I totally spaced! I have Blue sitting in the garage. I'll measure it when I get home and text it to you (and post here).

    I seem to have one of these two shocks from this post up above
    Honda CBR 900 RR 1996-1997 305 (+12/-0) 60
    Honda CBR 900 RR 1998-1999 303 (+12/-0) 57
    I think the spring rate is too stiff. I tried to set sag and I barely get 1" of compression when I am on the bike. Oh well, too late. It's way more stiff than my xb, I can squish the xb tail a lot, but this shock is super stiff. I guess I'm gonna have a rough ride.

    Welded a tab on the swing arm and mounted the canister here. I had to mount the shock upside down for clearance reasons, which dictated the canister mounting location.

    High up rear. Not sure if you can tell how much the bike leans over on the kickstand, it's pretty crazy in person.

    Here's a reference point measurement. Lee, do you still have your picture you texted me of your height on blue? I lost it.

I believe the blast rear shock is 10.5" eye to eye and a '87-'90 CBR600 rear shock is 11.5" eye to eye, and the early 90's Yamaha FZR 600 rear shock is 12" eye to eye. these will both fit the blast with little or no mods to the bike it's self. One of the bonuses of using a take off from a different bike is you can get the length you're looking for as well as goodies like compression and rebound dampening adjustment and adjustable springs depending on which model it came off of.




    That Yamaha FZR6 you mentioned.... that had a clevis type lower mount? Can that be changed to eyelet?
