i was trying to put my fzr4 starter moter in me fzr6 engine and could not get it in there,after investigating i found that they have different size ends but all the gearing in both engines seems same to me,are they different for a reason or just to make money ? also ive read about engine swap on here will i have to do the same with electrics as my bike is older ive a 3en1 with nowt but wheels on ive got all the other parts to it,but ive got me engine in there now bit ov a struggle on me own but its in there now will i be able to use relays from a 400 loom in a 600 loom ?

Knowing Yamaha, if it can be shared - it will be.

So, in this case, probably not.

Relays - well, they are just relays

welcome to the site..

I doubt it's "just to make money" if Yamaha can keep things standard they will, like any company really, standardisation is the key to manufacturing. I didn't know the two starter motors were different, it might be that the 600 engine is a later year.

I'd use the a loom and CDI to match the engine, so a 600 in this case. I wouldn't use the T'Cat because it has a TPS which causes some problems but the 3HE or Foxeye will be fine.

So, picture then

yeah ive got fzr 6 3he loom and getting same cdi to mach.didnt no wot relays were till i asked someone,im going take the battery out one ov the bikes to see if this starter turns it over or not,cheers

do you have to put the oil cooler rad on or will it run ok with out one ?

It should be OK without it, I think there was only one year the 600 had them.

great stuff save a bit ov money thanks

hi ive got meself r6 back end plastics,and got my eye on r6 subframe and undertray buzzing,but its bare apart from undertray do you now wot else i will nead from it so it all works ok bit of an ASK i no but if anyone will they be on here,also is it poss to run a 17" rear in 3en1 arm wiv a bit ov modding as i like this swing arm,i do have a 3en2 arm also but would like to keep the right one if its possible,ive looked and wonderd if you can make a bracket for caliper bracket on the arm to fit the new disk size ? ive got the 17" XJR rear wheel ready for it. me loom and bits should be here mon.and the fun begins
im looking forward to the knowledge i shall get from doing this bike,im just wondering how long its going take me ha ha.
i will try or just get me son to put some pics on here for you to sea.

The R6 rear end usually looks crap on these bikes, none of the lines from the fairing work and its all to narrow in height and toowide for the rest of the bike.
The XJR wheel should bolt in, not sure if the FZR disc will fit the wheel, if it does then happy days.

Most R6 back end conversions don't look right, as they hang too far back.

The R6 Sub Frame can be shortened and narrowed at the front end to fit nice.

Also allows you to decide what angle you want it set to.

Put on a Thundercat Tank aswell. Really nice fit along the outside line of the frame

Don't forget you will also need a Back Light,be it a standard one or an LED
