Re: Yamaha YZF750 Tech 21 Fujimi

Evilduse - the Tech21 Yamaha that is in the "Racers" magazine is the 1985 FZR750. The one Andrew is building is the 1987 YZF750 - they are different models but as I stated the swing arm I believe came from either a Honda RC30 or the Honda 650 Hawk USA models. Many of the endurance racers at the time here in the USA used the more available Honda Hawk650 swingarm which I believe was the RC31 USA model - it was a single sided swing arm twin cylinder 650cc Bike - they were widely available here in the USA and many racers adapted the swingarms into other bikes for faster wheel changes in longer endurance races - namely the WERA endurance series and the Daytona 200. The Tech21 YZF750 of 1987 was used at Suzuka with such a modification
Andrew I think a little more restraint of the brake line will keep the line from making contact with the wheel - Like I mentioned before I would look at pictures of the RC30 to get ideas about the rear brake line configuration - they should be similar in form and function. Also Andrew the black tubing you are using for the rear brake line is too large a diameter for the scale of the bike

Maybe a different version that doesn't show up in my book. In all the pics I have the brake line runs down the opposite side to the chain and connects on the outside of the caliper which is very different to what Fujimi has done in your pics. Do you want me to scan some of these pics and send them to you or do you already have reference pics?
