spoke to fastline today and they are willing to pay for the top end rebuild kits on my bike so im well happy!!!!
all i have to do is take the recipt from jap4 to them and they will sor it out.
this is good because i would buy again of them knowing there after care is good....
also anyone whowants an nsr..................... they have 10 on the way!!
The question is are they going to pay for a new barrel? Or a replate?
Top end kits at proper trade to a shop with their contacts will be very cheap. _________________ Please do not PM me technical questions, if you can't find it on the Forum start a thread
A "roughed up" looking piston doesn't always mean a shagged barrel. Of course, you want to give it a bloody good check over, but there is a possibility that a used piston has been cleaned up enough and fitted to get the motor running to shift the bike (out of Japan).
The Honda plating is actually bloody good, and very resilient. It can often withstand a seizure when you would normally expect it to be trashed, unlike after-market plating that I have even seen peel away from a bore! What isn't so good however, is any damage around the top of the barrel caused by detonation. _________________ Andy.

the barrel was fine, just the piston was damaged so i was lucky really. i have fitted both pistons now so im happy again, im just glad i could do the work myself because i wanted to inspect the barrel and also i know the rebuild has been done propper!!!
Sweet, I've never seen a barrel not sustain ANY damage, the one I killed on Thursday is OK, I'd use it and it'd run, but it's not perfect by any means.

Hence my general preferance for a decent 2nd hand barrel, come on, how many have you seen not damaged but out of tollerance?
I'm not too concerned about knackering a barrel, taking the crank out or playing russian roulette is the bit that I don't like.
However the last 2 I've seized were replates and didn't rip chrome off so my faith is somewhat restored. _________________ Please do not PM me technical questions, if you can't find it on the Forum start a thread
Probably not 50% of my failures personally, but I've not seized that many myself either!
I have seen more than a couple that were not only more than happy to go again after a seize, but also look just as good as they were pre-seize once cleaned up. I'm not making it up you know!
What can save a barrel is catching the clutch extremely quickly. What does trash them are parts of rings, ring locating pegs, circlips, and broken bearings bouncing around in the combustion chamber.
You'd be surprised what can be reclaimed. You may even have a couple barrels yourself that would clean up. _________________ Andy.

The problem is (on the road) I tend to ride them home.
The one at Brands was trailered back to the paddock and it looks OKish, I reckon it'd run, there's a slight score down it, but as you say, if I'd been quicker on the clutch even that wouldn't be there, it didn't lock with the clutch out (I'm quicker than that) but I felt it drag, whipped the clutch in and it just died. _________________ Please do not PM me technical questions, if you can't find it on the Forum start a thread
Bring them down next time you are passing for a rainy afternoon and we'll have a look at them!
I ran one with an awesome score in it for years (that's how it came from Japan/importers incidentally!) and only knew about it when I came to do a set of rings. It looked like the pin had caught it at some point, but it had only marked the barrel up to the bottom of the transfers so wouldn't effect compression. I made sure the score (which from memory was a good 2mm x 1mm x 30mm!) was well chamfered and slapped the new rings in. That barrel lived for 11 more years... right up until I met Steve and destroyed 3 barrels in 12 months! _________________ Andy.
