Still a work in progress unfortunately. Funds are a bit tight atm so I've been concentrating on tidying up my IT200 as my regular rider for Vinduro's. Going to pick up another project bike today out Cowra way, so I guess the Maico takes another step backwards. Hopefully 2015 will free up some bike $$$ to inject into these projects.

After a very busy 2015 it's great to get back into the shed. Have been working on the fuel tank and is progressing well, still a bit to go. I noticed how much softer and easier it is to work with Acerbis tanks rather than the Takagi tanks on Jap bikes.

This is the main suspension linkage. It doesn't run needle roller bearings like most bikes but rather metal backed brass bushes. The outer bushes are butchered but managed to get new ones. The inner bushes are the same dimensions as IT465 gudgeon pins so I'll grind down the pins to suit.

Gudgeon pin with new bushes, perfect fit.

The second linkage will however need a new inner bush made. Unfortunately the gudgeon pin is not long enough otherwise I could have used one.

I've started polishing the swing arm and lower fork legs which were painted grey but in the original sales brochure they are polished so that's the look I'm going for.

Brooksie. Here's my project. Frame is now blasted and coated, - engine & shock rebuilt, seat recovered , new plastics, pipe straightened - now I just need to pull my finger out and reassemble it. I'd like to get some better radiators, the oem jobs look weak with the plastic ends, these were changed in 86.

She looks very complete and original. Do you know the history of the bike. I'm not a fan of the plastic radiators either. I would be keen to get some made in aluminium.

I'll pick your brains also, I have a tear drop shaped washer with a small hole in it mounted off a swing arm linkage bolt. Not sure of its purpose. I'm pretty sure there should be 2 off them but I only have 1. I will try to post a picture.

If you must love a red bike it may as well be a maico 😁

This is an original sales brochure showing the lower fork legs and swingarm polished however mine and a few others I've seen are painted an industrial grey colour.

I've stripped back my swingarm and I'm going to polish and clear it as close as possible to the brochure. All I need now is a better pair of radiator shrouds.

Cheers GAD. I already have that issue of T&T. I also have the 3 way short out of the GM250 from ADB. Unfortunately the Maico was damaged in the test and was unable to complete the full test. It would have been interesting to see where it finished overall.
