Hi, Really impressed with watching this rebuld along with a few others from this site. I am new to the two stroke world....but had a 4LO-1 for quite some years in the shed. Decided to restored it to its former glory and stripped it down over the last week.
Not meaning to highjack this thread....but In need to ask some probably stupid question.
I get confused with these things such as:
the "Green Paint" on the horn bracket
the color of the bottom yoke, I did not pay much attention...but I thought that mine was also black.
the finish on the clocks and the "Green mounting Bracket" My bracket are original but appears to be black
The handlebar and the clamps that hold them on. The pictures above shows them to be satin black...what is the original color?
The back of the headlight???
I would appreciate if someone would clarify what the actual color scheme is as I would like mine back to as original as possible.
I certainly will be watching this rebuild with great care and hope to learn a lot from it to get my project right.

Thanks Bryan,
Either I have never paid much attention or perhaps all the bike that I have seen have been touched up at times.
i have already made one mistake. i have the lower youke powder coated black as well and obviously should have been green.
This build of yours is promising to be worth waiting for. I a learning a lot through all the write up and progress report. keep up the good work.

My numbers matching UK LC I sold a few years ago had Satin black lower yoke too, as I didn't know any different. Dosnt matter that much unless your going to be showing the bike. This restoration need to be as origonal as I can get it as that's what the owner wants.

owner managed to get standard head after a long wait, only to find when it arrived its had .5mm of the face and chamber volume is just under 20cc. Not too much of a problem, and as domes are untouched will be using it. Paint stripped ready for painting.  undammaged domes  all sprayed up ready to fit to the engine.  |

as these are £15 a pair, I dug out 2 old ones from my bits as they were missing on the bike, 15mm socket and the ball end of a hommer sorted the ends out.  Wire wheel couldent get in all the nooks,  so fired up the sand blaster and a quick squirt sorted them out.  back to bare metal with no rust. Quick spray with PJ1, job done!  |

wanted to get the engine to a point where its ready to fit in the frame next week. Treated myself to a new 3/8 drive torque wrenc for the smaller nut and bolts.  new pistons and a rebuilt crank.   we had a problem with the engine cases, at some point in its past it had a broken rod and damaged the front upper case, was welded up but cases still had a gap that you could see light through. While the Engineers were doing rebore and crank they machined a groove and stuck a strip of O ring in to seal it.  Laid crank in to check all the pins fitted, no probs.  All bolted up.  new 1.5mm pistons.  Gen base gaskets, always fit right.   first barrel fitted.  both on and head fitted to seal engine, need to sort out green head bolts yet.    |

todays job was engine in. As I was on my own again, Ive worked out a way to make it easyer putting it in. First put rubber hose over the ends of the exhaust studs so they dont scratch the frame, or leave them off till the engine is in.  Get some pipe insulation for the frame tubes and cover as much as possible, this allows you to lift the engine onto the frame tubes and rest it on the insulation while you get an arm over the frame and hold the engine from the other side to lift it in.   left the plugs out and the top hose housing off to allow a little movement upwards.  job done and now time to get bolting ancilleries on. |

today's first job was fit Hagon heavy duty springs.  origonal springs fit flush with the top of the fork leg.  Hagon springs are 4cm longer so will give a fair ammount of extra preload.  Got a pair of the top yoke wire guides from Yambits as they were missing.  Grips fitted  Throttle tube and cabel also now on.  Got one of the last few mising parts.  carbs fitted and ballanced.  stator and flywheel fitted, new neutrel switch and CDI on and all connected up.   Now have neutrel light.  And tool tray fitted.  |

thanks guys, all this work and it's not even my bike. pipes turned up today, quite serprised how good they are, not mint but think they are too good to respray.    why do people do things like this, just stick the correct type screw and washer on.  put a cheese head screw in to leaver the outer skin back out to where it should be.  |

must crack on with the build, been a few months since Ive touched it.
Got new rider and pillion footrests and the reproduced side panels in the post from Norbo today, look well made and have the 4L0 on the inside too. I can get all the bodywork off to the painters now.
Waiting for head bolts to get replated, need to spray the origonal exhausts and clutch cover then can get it running.

Looks lovely mate...Q- are the crankcases bare metal or laqured/painted in some fashion?
I also need some of the M8(i think) bolts and nuts that hold it together..

Post by bryan on Dec 18, 2012 23:24:40 GMT 1
aquablasted crank cases left unpainted.
Norbo or Redbimota should be able to help with the crancase nuts and bolts then you could get them replated. May nstill be available but you would have to order them and see what comes through.

got a new brake arm from Norbo and nut and trunion from Yambits.  new footrests fitted with SS bolts till I get the correct Yamaha ones, replated lower hanger bolt and new uppers from Norbo.  Had to strip my clocks down to get the trip knod off as it was missing on this bike. Replaced it on my LC with an alloy one.  Just noticed Ive not sprayed the nuts yet. Replacement air box strips from Taymar Racing as they were all missing.  |

Bryan. I am truly impressed by you build. Your attention to detail and the time you put into the forum is magic. I, and I'm sure the other lads and lasses really appreciate it. Also I can see what I need to do to mine to get it back to factory :-)
