I know all too well of what you speak. I've been a Radiologic Technologist for 25 years. I see many people come across my C.A.T. Scan table. As a matter of fact last night we had two separate bike injuries. One went to surgery with a nasty broken ankle and the other guy I CT scanned who came up short on a large triple at Lake Elsinore. I did get him the neck roll. Here is an update I posted on the All Thing Motto forum.
Hey guys,
Thought I'd let you all know how my 16 yr.old son's 1st ride went on the 2000 CR250 I pick up 2 weeks ago. As I had wrote in my introduction to this forum, I was concerned that I had possibly made a bad choice going from a CRF150 to a CR250. I had not intended to buy a 2-stroke but I wanted a bigger 250 4-stroke for our many desert outings (green sticker) but something suited for his track visits with his friends. I got a great deal on the bike so that was that. We went to the Hungry Valley OHV Park in Gorman Calif. for the weekend. I got the 1st ride much to my son's chagrin. The bike is very responsive, too responsive! After my short ride I turned it over to my son and reiterated for the 1 millionth time to take it slow and easy to get the feel of the bike. He came back smiling ear 2 ear and proclaimed 2-strokes are awesome! He did very well, so well he was the only one who did not crash that weekend. I didn't allow any hill climbs we couldn't avoid. As luck would have it his last ride on Sat. he came rolling in to camp saying; "What the heck's with my bike!" The rear fender was about 6-8 inches from the tire. The rear spring had snapped. I have never seen this happen before. So his riding was done for the weekend. I had one bummed teenager on my hands. The bike is now at Race Tech. getting the forks seals replaced and a rear shock rebuilt & new spring. Ouch!! $472.00 right out of the gate on a newly purchased bike. Also had to buy a new rear brake rotor ($96.00). Good thing I got a good deal. He loves the power and is already talking of ways to make it faster (ain't gonna happen). He whines every time I mention putting on a flywheel weight, "its good the way it is, don't touch it" he proclaims. I told him it would smooth out the power band, not slow it down. I think the 12oz. weight is too much after seeing him handle the bike. Now I have to decide between a 10 or 8 oz. weight. So far so good but I know his dirt sandwich is coming. One thing guys, I'm mixing at 32:1 as a prior owner did and the service manual suggests but the bike has a lot of oil coming from every crack and crevice at the end and at the mid connection on the tail pipe. We changed the packing before we went out and it was saturated. The bike was lots of compression when I kick it, so I'm doubtful it's the rings and it runs great. Could it be running way to lean? I'm hesitant to mix it leaner in fear of cooking the piston. One guy told me he runs his 2003 CR250 at 60:1 and the bike runs fine. I'm no mechanic but what should I be looking for?
