Does anyone out there run a YS91SR (long stroke) with a Curtis MP5/90 exhaust ?? If so what do you think of this combination ??

Is it smooth running, powerfull, starts easy and idles nicely etc etc

Thanks in advance

The SR91/MP5 combo is running OK but you've got a more suitable one (more power!) with the SR91/SB19 combo...

You can even improve the suggested combo by using a Kasama header...

The best pipe for the YS91SR is the SB19FH.

I ran the MP5 combo all summer and it ran great. I ended up destroying the pipe in a crash, so I switched to the SB-19. Holy cow, the SB-19 has more power hands down.
