Well ya but in the back of my head I knew I would be doing something epic/building a new motor. Leak down test when its all done.

^ on my first top end job and first banshee work ever, I thought the previous owner had Jimmy rigged something and I felt sick... then I realized the base gasket covers that area so it must be normal.seems weird there is a pocket in the case though...

Found blown base gasket that's where my high rpm or wot flutter came from and I had a plug wire get pulled out of the boot that why one side quit. Its cool though because tomorrow I'm dropping off my cyls and domes at cascade innovations for 4mil port and cut domes. Going 4mil long rod this summer ya budz! Shits gunna be awesome!

Left side is 4 mil drag ported 421cub, vf3, with shearers. right side is factory stock (Had to make a custom crank). also using itp hole shot on left and kenda claw on right. Shit works awesome!

Well on the case it looks like its filled with epoxy or something

What are the rubber plugs on bottom of cyls and case by cyl base for?

Sweet thanks for the help

Can't always flip the wheels. The valve stem will hit the front calipers

Right now one cylinder is set up for no power (actually inertial loss of power) and one is set up for mid to high . Just going to bore the cylinders and get new pistons and cut an inch off the plug wires Problem solver! Not going to buy a new crank this time

Now that I think about it, the wire might of pulled out of the plug but what about the high rpm flutter. Something is fucky here...

On a side note I could literally wiggle the positions while in the cyls. That's pretty far gone right? Planning on boring and getting new pistons anyways

It was making compression but it wouldn't burp out the tail pipe with throttle open while kicking over. Maybe a plug wire came loose would that cause high rpm flutter because that was my first problem then this.

Well I pulled the jugs pistons and cylinders looked fine. Im thinking ignition system problem now.Is carbon build up on the top/center on the pistons normal?

Make sure the throttle cables are seated all the way down at the top of the carbs.they can get pulled up and snag on the edge of the adjustment screw.

29l crank? Is that stock? Also a lil wiggle side to side OK in bearing on bottom of rod? Would like to do a 4mil a lot of people seem to recommend long rod but say I'll get more power with short rod. Would my stock ported cyls work with a 4mil or can it be ported again to work best with 4mil or would it be too late? Thanks for the help!

Last time I got pistons I just measured the bore and ordered pro x. L,r set up requires different pistons is that correct?

Stock stroke? Need to figure out what I need to buy. Going to have my stock cyls bored they are ported all ready.should I buy a new crank this one seems fine. I found one thread I think it might be a 4mil l/r but I'm not sure. If I buy a new crank I will need to get the same set up but a better brand

I all ready have it. Bought it like this. Is it 4mil long rod?

29l crank with y29l rods is it any good and is it a 4mil long rod?

My pipes heated up equally and I use 110 octane. As far as air leak wouldn't I get a run away or really hot pipes on one side?

Also it would feel like my chain was skipping teeth on hill shots or heave accel but it really shouldn't be its tight and sprockets are good also good chain guides and rollers good

Went to the dunes this weekend i started getting high rpm or wot fluttering in the high rpms so i started heading back to camp. So I'm fly in along in 6th gear. all the sudden I feel one side loose all power like the spark plug fell off. I didn't feel or hear anything weird like broken piston. I pulled in the clutch right away to prevent further damage it wanted to keep running on one cyl so I hit the kill switch. Waited for it to cool and checked out everything on the outside of the motor it looked fine so I tried to kick it over. Feels like I'm getting zero compression on the left side wouldn't even burp out that pipe with the throttle open during kick start. Anybody know this symptoms? I'm thinking blown out rings or crank came apart.

Did you replace your pilots?

Ported cyls, pwk 34, dynatek cdi, t5s, +4 swinger, cool head 19 domes, hot rods crank and rods fox shocks just to name a few so ya, its stockish
