Hi everyone, I am new to this forum. I was wondering if anyone is able to tell me whether low compression can cause bogging at certain rpms? I have a 01 rm250. I have jetted the bike so many times and currently running stock (stock pipes). Compression at the beginning of last season was about 172-175. As the season neared the end I noticed loss of power at certain rpms. Good top end speed. Bike also smelled a little like burning at the end of a ride (at exhaust silencer). I also just replaced the silencer pack as it was way over due. I am going to do a new top end before the start of this season. Looking for any other suggestions for my bogging. Thanks for your help.
