I have a CR480.....for an old bike, I just love the thing. It has a boat-load of torque, a really fun carnival ride.
I have a routine for starting the thing, but the first time I thought I tore a hole in the bottom of my work boot, I knew I was in for a work out. I bought a pair of Sidi boots to make it painless, but kicking the big beast was still a chore.
I was across town and stalled the bike one day (tall street gearing...stupid mistake) and I thought it would never refire. That was it, I wasn't putting up w/it any more.
My CR500 is almost complete....a new top end, so I knew it would be the same issues with that one as well, but on a larger scale. So, the 480 was to be the test vehicle.
I located a vendor for the self-cancelling (stainless steel) valves, pulled the head, drilled/tapped the hole and screwed the valve in place.
I can't believe the difference.
Snap the valve down and kick away.
Before I'd have to bring it up to TDC and jump on the kicker. Now it's like kicking a strong 125. Cold, hot, or flooded, it doesn't matter. It'll bust off with 3/4/5 kicks every time....I could start it w/tennis shoes (not that I would).
I was out running a few errands and had to make several stops. It's a pleasure to know it'll start easily every time...instead of the fear of it possibly leaving me stranded.
I'm a firm believer now in decomp's.
