Hi, guys! This thread is quite timely as I have, just yesterday, received my first batch of Red Zone stickers for the '750, plus a new run for the '550.
I'll be preparing a thread, but if you guys want to be guinea pigs, give me a PM with addresses and I'll send you out some stickers. The '750 stickers include, in addition to the Red Zone decal, a stripe to replace the "70 MPH" marker on the speedo, so it's a pretty comprehensive kit.
Price, when I officially release the kits, will be around $10 apiece. They'll consist of two Red Zone stickers and four "70 MPH" stripes. The Red Zone stickers have markers so they can be cut down and used for other applications (K0, K1, for instance).
I've been having trouble finding an acceptable printer. My first batch was done by a company that went out of business shortly afterwards, so I tried a couple different places with terrible results, which left me a bit gun shy and I had to table the stickers for a while.
The new ones look good, though; so send me info and I'll send them out! (limited to the first five respondents)
