A quick question for the suzuki "brains trust", I am getting closer to finishing a rm 125 B. this will be a competion bike and my query is to do with the exhaust. I have a standard rm 125 chamber in reasonable condition ,but I dont have a muffler, a quick look on the internet and I am having trouble finding a muffler for this particular model. Can I use the RM 250 B muffler on the 125 pipe? Also is there a after market pipe available for this bike. Thanks.
