ryansomething Posted March 1, 2015 Report Posted March 1, 2015 So i blew up my banshee a while ago and now have the funds to fix it. It was my first banshee and i melted holes in the cylinders. Ive picked up a set of jugs and want to start fixing it. Ive been going through the site here and have learned alot. I dont know much about the bike its self. Since i had the jugs off i did notice hot rods on one of the connecting rods. I guess my question is what are some things i should check while the jugs are off. i know it has v force reeds, cool head, and paul turner pipes. What mods and how should i check for? How do i inspect the lower end for and wear/damage. Any help is appreciated. Alos the jugs i got look like they might have some port work done. How do i know if it is a good port or junk? Quote
ryansomething Posted March 1, 2015 Author Report Posted March 1, 2015 Im not sure what happened to them. I think it got hot and lean. The guy i got it from did say it was 90 over so probly pretty thin too.I just knew it wasnt good when all my water went out the exhaust and exhaust went in radiator. Ill try to get some pics up tomorrow. I know the old jugs were ported. What is case match port and how do i identify it Quote
trickedcarbine Posted March 1, 2015 Report Posted March 1, 2015 Pistons melted? I would seriously consider at least splitting the cases and at least inspect the crank and bearings. Do you know what stroke it is? Quote
ryansomething Posted March 1, 2015 Author Report Posted March 1, 2015 I have no clue about the lower end other than that rhe rod says hot rod.. The old cylinders got a hole between the waterjacket and the cylinder wall. What and how do i inspect the crank and bearings Quote
ryansomething Posted March 1, 2015 Author Report Posted March 1, 2015 imma pull the crank tonight. how do i identify it Quote
trickedcarbine Posted March 1, 2015 Report Posted March 1, 2015 Easiest way, toss a jug and piston back on one side. With a caliper, run the rod of the caliper touching the piston on left or right side of the bore over the wrist pin all the way down to bottom dead center. You'll know you're there as the measurement on the caliper will begin to reverse as you pass BDC. Now. Zero the caliper out with it in the same location. Rotate the crank so the piston goes up to TDC. The highest measurement will be the amount of stroke. 54mm is stock stroke, 58mm is 4mm. If you don't have a caliper, you can just use a machinists straight edge on the piston. And take measurement off it from the top deck of the cylinder. Just roll it all the way over and make note of the highest and lowest measurements and find the difference. If you don't at least have a straight edge it's not something you should be doing. Pick one up at a tool store for cheap. If you get 58mm, take note if there was a shim plate between two gaskets at the base of the jugs, or if the head has work. Also take note of all the markings on the side of the Rod. CK158 would be a 115 rod and you need a piston with a different pin height to work with it. Quote
