So I have an 07 cr 125 fouling plugs before the bike even has a chance to warm up, plugs come out wet and oily on the tip. had both crank seals replaced last season because my main drive side seal blew. While it was split I had a new crank put in, we noticed my cylinder plating was pooched so I sent my cylinder off to be re-plated, put a new piston in the shiny new looking cylinder put the old warped head back on and called it a day. then rode it all season having absolutely no idea about the warped head because I overlooked it when I was excited to put my bike back together and ride. Its now winter, snows on the ground. I recently went to go for a put and fouled a plug before I could get to the end of the street and back. I was also smelling coolant so checked the rad while running the bike, lots of movement and tiny bubbes. Pulled the head off and sure enough it was warped to the point where I could rock it back amd fourth on the mirror and see a small gap... so NOW after I replaced the head my problems persisted and I can still see little bubbles swirling around vigorously in the rad if I rev it with the cap off, I've had boiled it down to my cylinder probably being warped then I found a leaky hose by the exhaust that was dripping coolant onto the outside of the exhaust port. Which brings me to what I think may be an incredibly stupid question, could it just be the loose hose sucking in air that is causing my rad fluid to have small bubbles in it? And maybe im just experiencing increadibly rich jetting now that my head is actually sealed properly? over and out.
I have a 2003 YZ450F and sometimes it can get pretty hot while riding slow and technical stuff. The temperature has gotten up to 240 maybe even 250. To the point where it pukes Coolant. I put a overflow catch tank on it and a Boyesen super cooler water pump and it still gets up to those temperatures. My question is, is how hot can it get before I start doing damage to the engine? When I see it get hot I do stop and let it cool down. I just want to make sure I am not doing any engine damage.
Noticed my bike boil over on a recent ride, then noticed my fan wasn't working. I found the little box of 5 fuses under the ECU and one was blown. Replaced it, rode yesterday, and the fan never kicked on, despite some challenging, slow riding. This morning, I checked the fuses again, and sure enough, the fuse was blown. I'm no electrician and know enough about motors to be dangerous (always just ran a 2 stroke before this bike because I could understand them) but I'd like to fix this without having to take it to the Husky shop, pay a bunch of money, and not have my bike to ride. I'm thinking it probably has to be some kind of short in the fan itself, but has anyone experienced this? I'd like to know if there's any other thoughts before dishing out $100 for a new fan. Also, sometimes when riding, the bike would idle high, which I am assuming is because it was running hot. Never boiled over, but do you think it could have been running hot enough to do any kind of damage? I'd think it would boil over before it got to that point, but again, no mechanic here... Thanks, Will
