Project Stumpbroke MS290

[Stumpys Customs]

Cut the Muffler appart & gutted it. I cut the bolt tubes off & held them in with the bolts when I welded it back together.

Those are interesting stats Stump!!! Is the throttle response a lot better now?

 

[sunfish]

Good improvement. Very good. Especially for a 290!

It has a slight lull right off of idle. Probably due to the high intake duration, but other than that it's very snappy with plenty of pull. The last three tanks were noodlein some oak that was longer than the bar and it held rpms even when I was pushin it hard. It's getting better with every tank I put through it. I'll admit that it turned out to be a lil hotter than the work saw I'd planned on.
