RD500LC and FZR400RR project
Updated
: 21/02/2012
I've recently bought an FZR400RR type 4DX / 1993 in order to make a nice alloy framed RD500 for track day runs.
In
this page I will try to give news from my
project.

FZR400RR from the breaker and lot of parts will be for sale soon like : - engine 47000Km on clock ear it - electrical stuffs like CDI units... - exhaust pipe with EXUP and MIG can (photo) |

FZR400RR stripping it down |

Second hand radiator buy from UK thought e-bay The 4DX radiator is the same as the SP because of the oil cooling system but doesn't need it for my project. For information on FZR400RR and SP see Richard Halford pages The radiator fan has been removed and fit on the bike for testing and no leaking problem. |
|
I buy a TZR 250 coolant tank in order to use it in my project behind the steering. |
|
10/08/2005 This is the rear huger from a YAMAHA thundercat that I'll adapt to the FZR400 swing arm. I'll need to modify some mounting but it seems to match quite good in my first test. |
|
16/08/2005 This is an empty engine
build with my spares parts in order to make the mounting plates for the
RD500 engine in the FZR400RR frame. |

|
16/08/2005 I'm actually removing the 4 strokes parts from the bike :
|
22/08/2005 I bought a batterie eliminator and I've tested it on my YAMAHA 200 DTR commuter. Works greatly. |
|
26/08/2005 I bought an used set from ebay in the UK (only done 25 laps at Cadwell) |
|
31/08/2005 I've just bough a pair of Japanese specification mirror from a 3TJ FZR400. they are much nicer that 4DX stock mirrors |
|
|
02/10/2005 I've removed the FZR400 engine and try to put my rd500 mock-up Points to be checked :
|
|
09/10/2005 I've ordered the 16T 520 front sprocket so the alignment will be checked. My Jolly Moto stock pipe will not fit so I'll need new upper straight pipes to fit according to Jolly Moto pipes I've found SDR 200 pipes drawing on the Web so I've made a paper mock-up of these pipes to check with the frame. I've made the assembly of the paper's pipe. I'm looking for the Jolly moto sizes in order to modify the first part of the pipe and use the fat part ? |
|
14/10/2005 Lower pipe fitted in order to check frame clearance. Looks OK. I still need to test it again but it's look fine for the lower pipes. Still waiting for the front sprocket in order to build mounting brackets for the engine (I've already bought the tube and metal sheet to build temporary mounting brackets. |
|
15/10/2005 Upper pipe mock-up fitted with the modified subframe. Not enough clearance but I need to make some measurement on the Jolly moto pipes. It seems that bigger diameter is 100mm not 110mm like my mock-up. I'll also build a rear sub frame in order to obtain more space for the upper pipes under the seat. |
|
24/10/2005 I've made some measurement on my Jolly Moto upper pipe and I've built paper mock-up. I think that a new sub-frame for the seat unit will give more free space for the pipes but I think that the pipes are too close to the tyre. I'll do some testing as soon as possible. |
29/10/2005 I've done some measurement on my upper pipes and I've tried to modify the 3rd cone to give clearance to rear wheel travel. Different angle values : 5° 8° 10°. |
|
02/11/2005 I've modified one of the straight pipe have al ready made in order to check the clearance in both directions :
|
|
|
03/11/2005 The bike on the paddock stand with the two bent pipes and also with the rear huger. The space for the rear wheel seems to be enough with rear shock with race set-up. |
