Raise CB750 Rear End w/ Reversed Lowering Blocks?
« on: September 21, 2013, 01:40:12 PM »
I've got an extended swingarm from a 79 my 78 and would like to correct the shock angle/performance.

Been searching around but could t find much. Can you use lowering blocks reversed/backwards to correct the angle and raise the rear end?.

Is the swingarm Aluminum, or steel?

I'd like to know the answer to this too as my Kerker scrapes on hard cornering with the small rear tire on there.

Chewy, unless you are regularly scraping your pegs {stock mount}, and i mean folding them up, then its more to do with the design of the pipe than a ground clearance problem. I have noticed, for some time, the fact that pipe manufacturers in the USA, especially in the past, make a lot of lower slung pipes which touch down easily. We had a company here in Aus that made a pipe very similar to the Kerker in looks but the mount for the rear section was actually under the pipe where it then bolted to the rear footpeg mount so the rear of the pipe was above the rear peg and could never touch down. I never use center stands on the 750's either as they scrape too easily.  Just saying this because of all the 750's that I've owned, they all had 4into1's and I have never scraped a pipe, scraped everything else, but never scraped a pipe, most of them had stock length Koni's on them.... ;)

On my buddies K2 , he for some reason welded up his pegs..mostly i think ..rather than crash bars..
 Anyway he used to run TT 100,s, and would corner so hard the pegs got bent up at about a 10 degree angle. Eventually he went to Morris mags, runnng a 16 on the back.. Then ran Goodyear RWL .. AT..i think they were ..still cornered like a madman..
