I have a couple questions about 2 strokes. I just bought a 94 yz125 off here. I was looking for a spark arrestor for it and found out no-one makes one. Ther are only 2 silencers available for this bike. Can you just take the pipe apart and put a screen in it? Another problem is that both the pipes I can get are factory sound? Is there anyway to overcome that. I would like it a little quieter if possible. I was also thinking of buying 2 silencers and switching the pipe end to a spark arrestor type silencer. I'd rather not do this because of the cost if I can avoid it.

The second question involves flywheel weights. The bike is going to be used to putt around with my son in the woods and also as a sometimes pit bike. I can get an 8,10,or 12 ounce flywheel weight for it. What are the pros and cons of the different sizes.

Thanks
