On my mt10 I took the wires off the servo to the exup flap and lock wired the flap open, took a flat spot away. Later put a decat pipe on that done away with it all. It's something free to try 1st I guess.
Great video ! I bought an 88 and 90 models new back in the day. Even by todays standards, the handling is great. Thanks for the memories. I'm 75 years old now and ride a ZX-14r, need that comfort to go with the rush.
Owned the pre-1989 FZR1000 EXUP in red and while (best colors) and even the FZ750 (Serius 1) prior to that. They were 'pure magic', even compared to other sports bikes I owned.
When i was 17 I took the new 85 GSX-R750 out for a test ride, with the intent of trading in my GPz-750 for one. At the same time my mate took an FZ750 out for a test ride, we met up on the edge of town and for the next hour thrashed both of them, swapping between bikes. In the end it was the FZ i ended up getting, fantastic bike. I'm restoring an 87 FZR1000 at the moment, love 5 valve Yamahas.
Great bikes, I had the Genesis and later EXUP.. It was generally the earlier pre-EXUP FZR’s that were referred to as the Genesis. I had the blue/white Genesis way back in ‘91. Check the EXUP valve though, it has a tendency to seize
hello guys nice bike I had an 91 fzr back in the day and the problem I had was the emulsion tubes were worn out and Oval, the tubes that the needle goes through i mean. if you feather the throttle at about 4,000 the bike would Lurch and then it would come right after about 5000. I think Dynojet do a kit ? Cheers from New Zealand
87 88 FZR 1000 was a 990cc 20v two head lights like the fzr 600 and then 89 90 was 2nd gen 1002cc 20v with the exup with two headlights but they where rounded not flat my fav years then 91 92 motor was the same but they went to one head light 93 and newer motor still the same but they when back to the two head light look but cat eye like the YZF 750
Yamaha invented the 5 valve concept, the first road bike to use it was the 1985 FZ750. I wonder if Audi/VW & Ferrari payed Yamaha to use it🤔😆. Toyota, being big buddies with Yamaha, probably didn't, they helped Toyota develop the GT2000, Toyota's real sports car, and have been helping Toyota develop their engines ever since, the LFA V10 is a Yamaha designed engine. Also EXUP stands for, Exhaust Ultimate Power Valve. Nearly all the other manufactures started using a version of it as soon as the patent on it ran out after 10 years.
I picked it up last week and the petrol tank has now been painted. It will be going up for sale shortly. We will be doing an update video soon we hope. It's an awesome bike but I can't justify keeping the 2. Thanks Ken
