That is the best compliment I can ever receive. That is the goal, to make a custom bike look factory. Thank you very much

This exhaust looks so good. I wish there was a way to leave it bare metal, it's a shame to cover up all the welds and workmanship!

For real, this bike is looking great! When I got my wife's cm400, I was a little bummed at first. Your workmanship and clean ideas are really inspiring!

Re: Sin City CM400 Cafe Racer *new pics of triple tree and carb spacers*
Hi all, another busy week working on the bike. I was able to finish running all of the wiring with help from a buddy of mine. The main harness is run just need to tie up a couple of loose ends like the headlight/ brake light switch and license plate lights. The wires are run just need to make final connections. We were able to hide pretty much all of the wires in the frame so it all looks really clean. I also finally got the upper triple tree finished. I was able to do alot of the work on the bridgeport but some of the radius were just to complicated for me to do properly. It needed a blueprint and a program to do right. Luckily I have a great machinist to do complicated stuff for me when I get in a bind. He did an outstanding job and the bracket that holds the speedometer cup looks killer.

Re: Sin City CM400 Cafe Racer ***new pics of exhaust and carbs**
So after getting the triple tree and gas tank mounted I started looking at the carbs and the routing of the throttle cables. Its pretty straight forward but i didn't like the way the cables entered the carbs. It was just too tight of an angle and I hate when the throttle doesn't turn smoothly. Usually that's because of tight turn in the cables (when using new parts). Also looking at the carbs and where the petcock is on the gas tank there was very little clearance between the 2. Maybe a 1/16th of an inch. Not enough with the tank being rubber mounted. So I decided that I could make some manifold spacers to move the carbs away from the motor about an inch. This will allow the cables to work better and give more clearance for the petcock. I realize this can affect performance, not necessarily in a bad way but affects it nonetheless. Luckily the original carb manifold are about an 1/2" longer that the ones I am using so in reality a 1" manifold spacer is moving the carbs 1/2 inch further away. I can adjust that out with tuning to make the effect minimal, maybe even gain a little torque which wont be a bad thing on a 400. Here is what I made

Re: Sin City CM400 Cafe Racer *new pics**
Those intake manifold spacers were the last parts I needed to make for the bike. So I took them, the exhaust, the foot controls, and a bunch of misc parts and sent the out to The Powder Pro for what I hope is the last of the powdercoating. So once that's back it shouldn't be too much longer to have the bike wrapped up. The end is in sight, and itching to start the next project!

Re: Sin City CM400 Cafe Racer *NEW PICS*
So the bike is at a standstill until I get the powdercoating back from The Powder Pro. Don't get me wrong, they provide quick service and I should have it all back by mid-week next week. I've been killing time by making a couple really cool one of a kind details that I will show when the bike is completed. So hopefully next weekend I will have a completed bike to show on here.

Re: Sin City CM400 Cafe Racer *NEW PICS*
Beautiful build,
Well thought out,
Great attention to detail,
Very nice fab skills.
I am in the final stages of a 1980 CM400T Cafe build as well.
We did a lot of similar things ...spokes, VM30's, front drum, longer rear shocks, custom exhaust turning out before rear tire, ......
But in retrospect you did many things the way I wish I had, the Sub Frame and Alloy Rims in particular.
I have LOTSA questions. If you have answered this somewhere earlier in the thread, I apologize...I blame it on the great pics..lol
SHOCKS
How long are your rear shocks?
Any concern with chain / swing arm contact while fully extended/unloaded? (Swing Arm Angle)
CARBS
*Did you buy a VM30 "CB350 Sudco Kit" or piece it together?
*How did they come jetted and what jetting do you expect to start off with?
*Are you using Mikuni Mounts with the spacers you made or some other type mounts?
*If Mikuni Mounts, are they VM30 Mounts? How was the CM stud to the mount hole fit?
BRAKE PEDAL / LINKAGE
*Any concern with, or how did you deal with, rear set pedal length compared to OEM Pedal length and the change in "Lever Force" applied to brake with foot pressure. ?
*This one gets hard to describe / ask, The OEM brake pedal "Pivot Point" (and front rod linkage) is very close to the Swing Arm Pivot point to maintain a constant distance to the Rear Drum Lever as the swing arm / wheel moves up and down. With a new Brake Pedal "Pivot Point" and Front Rod Linkage point,
Do you have any concern the force being applied to the rear brake by the new pedal will change, as the rear suspension moves up / down possibly changing the distance between Pedal Lever and Drum Lever?
I am so happy to see such a quality build to a modern twin CM/CB, the early twin guys have it easy with "off the shelf" parts and tried and trued Mods.
Your bike should greatly help to give these bikes and builds the respect they deserve.
