Hey guys I was wondering what bike I should get I havnt rode since I was in 7th grade but I had a kx 85 so I was experienced with riding I could pin the bike on tracks so I'm not completely new to riding now I'm 6,2 190 I was contemplating what bike to get, should I go with a yz 125 or should I go with a yzf450, I would never sell the 450 prob have it forever thank you tell me your opinions plz!!
Hey all, let me get right to the point, basically for the past couple years I've had this bike, it hasn't been running right. It tends to start well, and has a decent amount of power for a 200+ lb kid on it, but once I attempt to hit the top of the power band, it tends to cough and sputter like it's choking. When I recently checked to carb to jet it, I realized ALL but one of the Jets are missing. I've checked the reed valves, they seem to be in great shape... However, today (it is a warm day) it ran great for a while, after topping off the oil and running with the choke half on, this bike also leaks oil, but I'm almost convinced that this is a jetting issue (being that they're missing) at this point, but I've also never put a top end in this bike. Thanks for any help, I'd just like to get an opinion on what you guys think. I know I'm all over the place btw, sorry for that
I have looked all over and cannot find a good accurate resource out there. I recently decided that it was time to tear into my 1990 DR350S. (suzuki) it would not run reliably or really at all anymore and I found that the compression was only about 80PSI. After tearing into the motor I found that overall it was in pretty good shape.. the Oil ring was stuck inside the piston so that it was not sealing well and it appeared that the valves may not have been seating well. Really I figure I can re-grind or re-seat the valves, replace the top end gaskets and piston rings and it should be good.. what I am wanting to know is how do you know if you should replace more (valves, timing chain, ect..) I do have a strong Mechanical background but have never liked or done much engine internals.. any advice would be greatly appreciated. I do have pictures of the valves.. you can see them here https://goo.gl/NH76kw... let me know if that does not work and I can copy them to this post.
