I had a Banshee with a 404 big bore kit. I rode the
**** out of that thing and never took apart the engine. It was still running good 4-5 years after I sold it. Can't say the same for my hybrid. It sees 3 hours of use and something else breaks.
Right I'm thinking of having Shearer or k&t build me 4 mill 421 cub don't wanna go to overboard I figure 100-110 hp on race gas should be plenty to win a lot of local trophies.

We use to have a 421 cub that was drag ported by k&t. It scooted along quite nicely lol.
Keeping the Zilla here's what's left of my reeds. Took the exhaust off and scoped the cylinder with my rigid sea snake camera with a special 6mm hd camera head, found no remenants of any carbon fiber down in the crank or any if the ports or cylinder. Going to order some new reeds and run it.
Motor got hungry an ate the fourth petal?
Did you have the reed tension right. On the high setting.
The broken one is one of the inner/middle reed peddles.
Yea that wouldnt have any to do with it
Have you checked inside the power valve and pipe?
Well I found one of my reed peddles. Was stuck in the paper and wire fins inside my k&n filter. I figure this one got blown into my filter when the bike back fired and the other one got sucked through the exhaust the next time I fired the bike after the backfire cause I can't find any remenants of it at all.
Thats crazy
It really is...........damn!!
What did you figure out that caused the backfire? Timing , jetting?
Man you got lucky and hit all the glitches in this build!
Ordering new reeds from Jerry and some more jets for my carb should have it back together and running in the garage at least by next weekend if Jerry has the 88+ small v2 reeds available.
I'm assuming because the engine was loose in the chassis and moving a lot more then it should've been it was a grounding thing that caused the backfire. It never backfired the entire two days of its maiden voyage and I ran it hard as hell for a 9 hour ride one day and a 5 hour ride the second. Once I get the reeds and everything back together going to leak down test it and tighten everything down with loctite.
Loctite and lock washers are a zillas best friends! Glad you found
The other petal, i was gonna ask if you checked inside the filter
cause of the backfire.
Put my new reeds on last night realized I never took any pictures of my cylinder after I got it back from Matt "scam artist" Hatfield.
Are the two transfer port ceilings the same height? Right side looks lower
I believe so I took it with my phone and couldn't see the screen while shooting the pic so it's at a funny angle.
It looks like the one side is alot higher then the other one to me.
It probably is hack it up Matt hatfield had it after all.
Looking at it it could be distortion from the lens too
The port is a little higher on the left side. It is nothing to worry about. The port not being the same height on both ports in that spot will not hurt or help the performance or reliability. The only thing it should hurt is the feelings or cause embarrassment and or the reputation of the engine builder that allowed that allowed that type of craftsmanship to escape from their shop.
Thanks for the reassurance Jerry lol. And I highly doubt the quality of work the dumpster fire that is Matt Hatfield is going to hurt is feelings. He's a poor broken pathetic man.
Jerry's responses are always professional and very true.
Probably why I have two motors done by HPR.
