been looking at the ness low line frame i have and thinking its time to put the bike together with the hex cut barels and heads with polished cases that have been sitting already to go for way too long.

problem is i have a nos 16x4 invader with brand new 160 tire sitting that i want to use.

I know the chain will hit the tire. I dont want to make an offset sprocket for 1/4 i need. dont want to cut motor mount off the frame.


was thinking to weld the top holes in rear motor mount and re drill them 1/4 over and mill 1/4 off the vertical edge off setting the motor to the cam side.

new front mounts are easy to make so that is no concern.

think there is plenty of room around the primary


has any one done it tried it any thoughts on it??????
let me know your thoughts.

As far as your Idea just make sure that you still incorporate the Top MotorMount..

I'm thinking it's less work to machine the sprocket. I've seen one drag only sporty with the motor offset, and it definitely looked "off". In terms of man hours, the sprocket is the easy way to go. You've got the equipment to do it, it's just how much time you want to spend.

Yeah I would think a 1/4" offset sprocket would be easier. I think PBI sells them.
Or just weld the outer section of a new sprocket right on to an old sprocket with the teeth turned off it. They are about 5/16 thick so would be just about the right offset for ya.

But if you want to move the engine over, with rigid frame and no swingarm pivot in behind the primary case it should work. You would not think a quarter inch offset would even be noticeable.

other reason i do not want to offset sprocket is because of the week main shaft bearings on the iron head.

also want to try and keep the stockish sprocket cover.


on my supercharged iron head i made a 7/8 offset sprocket with a big twin primary bearing for support.

Mount all welded up and remachined. Looks pretty good and motor seems to look better in the frame.
