Hello, well you can get a fmf slip on straight from fmf factory for 199.99 right now. Then rejet the carb with different size jets. Then also get a different performance filter. Also i`m not sure what all you want but you can get progressive springs for the front off of xrsonly.com. I have the same bike i put a uni filter in it was alittle better but the pipe and rejetting should make a significant difference.
