Restoration by Nobby Toledo—USA
Nobby had two of his brilliant red and yellow Mugens featured in Issue 26. He mentioned at the time that he had a few more Mugen projects on the boil and here’s a look at his latest Mugen—a 1976 125.
From what Nobby has told us, it will certainly fly!
“I am really happy the way my 76 turned out. I did some different motor work to this one. I put in some ports in the floor of the intake that goes through the cases and feeds into the crank plus the boyesen ports that feed into the intake. I also put venturie plates in the carb, one in the rear of the carb right in the middle and two in the front —one at 1/4 throttle and one at half throttle.
The carb is a whopper—38 bored to a 39.1.
I also changed the pipe specs a little and as you can see I put the silencer on the outside of the bike instead of in the airbox like they came with the Mugen kits. I think it’s a lot better and cleaner application, and quieter. This bike really hauls the mail I am really pleased with the out come.
My next project is another 79 Mugen kitted bike. I found a 79 that I bought from the original owner that was all original down to the tires. He told me that it might have 10 hours on it and it shows. I am going to do this one in red and white like Johnny O’S first Mugen bike. I never did find a Mugen head for this 79 but I found a guy that has a 3D imaging machine that can scan my other head and make a program that is then programmed into another machine that makes a high strength resin mold that can then be sand cast. You can also put the program into a CNC machine and do a head out of Billet aluminum.
It is kind of spendy but a guy has got to do what a guy has to do. I have been looking for a year and half for a head and no luck and I have talked to everybody that is anybody in the Mugen circle.”
