Possibly going to look at a 954 tomorrow if the ebay gets back to me.

The question is aside from:

reg/rec issues
CCT sticking
2nd gear issues, or possibily fourth gear issues

What else do I have to look out for?

Check the recalls have been done... There is one for steering head bearings, and one for fork leg lowers I think.

Check the block hasn't cracked between No 1 and 2 cylinders.

Been quite keen on the idea of a 954 myself.... Never heard of this being an issue though! What causes it?

Well remembered Marjay, heard about the one regarding head bearings, will run a quick check through the VOSA site now to swat up on the fork lowers.

+1 to this?

Also how would I know aside from it running like a pig. I can't pull an engine down on the seller's drive.

The 954 is an overbored 929, they overbored it a bit too much....
If it has cracked water leakage will be evident, or plastic metal stuffed into the crack. Get a good torch and shine it through the front of the fairing to check.
Please dont start telling me its never happened... again.... there are numerous posts on the fireblade.org site regarding this.
It always seems to happen just out of warranty and Honda are a devil when it comes to admitting liability.

I heard about the block issue to when I was looking at the a while back.

Just basically as jjudgen said, they over bored it slightly to much.

Apart from that they are great bikes and other than the recalls and the other bits you mentioned I didn't read any other common problems.

I've heard about the 954 fork recall, think it applied to the 929 as well. The recall related to possible cracking in the fork lower casting. At the time Honda agreed to recall all UK models and rectify the problem regardless of warranty dates.

There was also a headstock bearing upgrade recommended but i don't think it was a recall. The upgrade was to change the tapered roller bearings for standard ball bearings, although quite why they would do it is beyond me.

Fair enough. Thumbs Up

Did a quick google and nothing relevent popped up, I'll have a check though.

EDIT, just regoogled. Shocked . Easy enough to spot though. This one's registered as an 02, so it seems less likely to be affected.

In a recent issue of Performance bikes they said that some race 954's had a problem with the crankcases flexing because the 954 bottom end was on the limit of the power it could take. I assume this flexing would damage the crank.

However, it never mentioned anything about the block, and it actually said that Tadao Baba, the chief designer of the FireBlade designed the engine to be 954cc from the outset as he knew it would have to be developed over time.

I've owned a 954, I've researched them in depth, and I've never heard of this head cracking stuff.

It seems to affect bikes in America, and warmer parts of Europe much more to be honest (Affects a couple of UK bikes in that thread, but it is an American forum IIRC). I don't think it's THAT common, especially in these parts. Still one to check for.

https://www.fireblades.org/forums/honda-fireblade/59854-cracked-crank-case-my-954-a.html

It's also suggested in that thread that Honda changed block manufacturer towards the end of 2002, hence that it's mainly 2003s that it affects.

To be honest I can't see how overboring a motor would lead to a crack in that location. Surely it's most likely to crack between the walls of each cylinder because it would be thinnest there?

Well it's certainly something I will look outfor if I ever go for one!
