General Discussion / Heavy throttle
« on: December 02, 2016, 03:50:08 pm »
Well I have been out of town working for 7 months; while I was gone I have purchased many parts to put my sandcast back on the road.  I replaced the tires, chain(diamond)and sprockets(17/45) , rubber intake boots, brake lines, and throttle cable.  The bike runs fantastic and handles great, the only problem I have is the throttle is very heavy to twist.  It felt a bit heavier with the old cable, which is why I replaced it.  I figured it would get lighter with a new cable.  It didn't,  it really starts to cramp my hand after ridding for a few miles... I have had over 10 cb750's K0's through f models and none had this issue.  Is this typical for a sandcast?  I have the cable routed correctly and the carbs are very clean.  I love ridding the bike its performance is definitely better than all of my other 750's ,by a lot....  Any advice on making the throttle twist easier?  Thanks

Do sandcast generally tend to run better and last longer than say k0-k8 due to them being more hand built and attention to detail than later engines?   Just curious because I have had quite a few cb750's and my new sandcast with 42,000 on the clock runs better and is quieter and smoother than any other 750 I have had.  It will idle perfect at 500 rpm which I find amazing.  I'm also trying to figure out if its been rebuilt.  I also found a red round sticker that was under the airbox it looks to be from the factory any ideas???

I purchased a really nice early sandcast today.  Its frame number is cb750-1001977 engine is cb750e-1002091. I checked the case in front of the sprocket and its solid no chain holes.  The bike was very customized has Lester's and a cool fairing.  The paint on the frame is very nice you can tell this bike was well cared for.  It has a wrinkled tank and number 8 bolts everywhere.  It also has the 9 hole clutch cover and recessed ignition switch.  Now to get it running.

General Discussion / Throttle cable question
« on: July 07, 2012, 08:18:10 pm »
I purchased a new throttle cable from Z1 enterprises .  It is the stock 1 to 4 cable setup.  I didn't adjust anything else and when I started the bike its idle was pegged at 3,000 rpm. I checked all the cables to make sure they were free moving , turned idle screws all the way out , and re started with the same problem. Do you think that the carbs need to be re synced due to the new cable?  It idled and ran perfect with the old cable I wouldn't think there would be so much of a difference between cables.  Is there something I am missing?
