bonzoid60 Posted September 30, 2010 Share Posted September 30, 2010 AFAIK, the engine & frame numbers for the SP model began with 4HS, 4HT, 4FN, 4HB or 4JA. Hope this helps. Link to comment Share on other sites More sharing options...

RedDevilSi1 Posted April 9, 2012 Share Posted April 9, 2012 Just wanted to tack onto this topic myself. I had a cylinder seize on my YZF and have bought a replacement engine. I just wanted to pick every bodies brains as I am not a trained mechanic and not got a vast amount of experience with bikes. I just wanted to know the best way to extract the engine and install the new one. Are there any specialist tools required or can it be done with a basic tool kit. P.S. I've seen people using hoists,is that essential? Many thanks in advance!!! Link to comment Share on other sites More sharing options...

Many thanks in advance!!! might have been worth starting a new thread for this. having taken out, and refitted an FZR1000 engine (which is externally much the same lump) a few times, i would say it is fairly easy. Refitting you need to get it back in in the correct order, but you will see that when you refit. i lifted the lump on my own - it aint light, but it can be done. make sure you have tons of bits of 4x2, 3x2 and plywood for supporting and resting the engines as you move them around.
