R6 Frame stamp

[bEN_]

Because i havn't passed my test yet i've been looking into this common problem with 2nd gear and whatnot on 99-02 R6's,
(even though mine is in exellent condition and has been looked after (when you look at all the paper work, anyway )

i've heard the ones that were recalled and sorted have a 'stamp' or something put near where the frame number is, just want to know if anyone has had this done, i checked mine the other day and there are 2 marks either side of the frame number dunno if thats normal or not so just curious really.
i've read up alot about it and it can be cheap to fix but like i said i'm curious.

none were ever recalled,if the problem occurs it is usually at higher mileage so most were/are out of warranty.yamaha never accepted responsibility or did a recall.

I heard differently. someone on this forum said that there was a recall, and a stamp as you mentioned. I cant vouch for this, but hopefully someone can clear it up

according to my checks the only yamaha recall on R6's between 99 and 2002 was 17146 bikes to have the sidestand screws replaced as they vibrated loose,no other recalls on those years.

it was never a safety issue,so yamaha did no recall as it was cheaper to repair just the ones that broke while in the warranty period.

dont blame them as its an engine out job.

a quick google search brings up nothing about the recall for the R6s. However, it seems a number of other yamahas were recalled in 2001 for transmission problems.

best off sending pm to the chap who made the post originally about the stamp.

apart from that theres not much you can do except look after it and hope it doesnt happen

Well ive been told that 99-02 r6's 2nd gear does go after about 18,000 miles. I bought mine when it was at 21,000 and it had this problem although i got the garage to fix it for free. Very expenisve job they said it would of cost me £800. I guess they go if the owners do alot of 2nd gear clutch wheelies. Although i did hear about places that actually can use that later model gear boxes 03-06 which intially fixs the problem.

some r6's were recalled and given a beefier detent spring. The detent spring is a 50p spring (take off a cover, swap a spring and replace the cover. Takes 5 mins to do and all you need to do is buy a spring, and a gasket-you wont lose any oil)

Its not really a proper fix, its like haveing a terminal shoulder problem, yamaha have basically given you a bulky arm, but they didnt fix the shoulder and its probably only a fix for 0.5% of bikes.

2 different symptoms for a detent spring brake or 2nd gear gone. Both are prone to going on R6's.
If you detent spring snaps, it wont engage 2nd at all. This happened on my bike.
Of 2nd gear has gone it will slip under hard acceleration, as if the chain is slipping off te sprocket or your back wheels hitting mud and spinning up. This also happened on my bike

The whole gear box is generally crud on 99-02 r6's and most of them go at about 15k miles (both parts broke on mine) a 100% fix is to stick an 03-05 box in. This involves takeing your engine out of the bike, spliting the crankcase and replaceing the box. Its not an easy job, infact its about the hardest, easiest to fuck up job you can possibly do. Its a 200 quid fix if you can do it yourself but its basically an engine rebuild.

my engine is currently on the work bench and im splitting it on saturday, my 03 box should be comeing mid next week, along with big end shell bearings etc. (im doing an engine rebuild while its appart) i think my selector forks are bent to buggery, i can take a few pictures if anyones interested?

badically 2nd gear wheelies do it, and hard acceleration in 2nd, voilent upchanges will bugger it. the fix yamha did isnt a bad thing, but it wont save your box if you ride it hard. at the end of the day its a problem with the bike, if you ride the bike hard be prepared to fork out for a box.

Yeah i read about the spring thing too, if it breaks it breaks, i'm not going to ride it being cautious all the time or there's no point me having it, i'd rather it fuck up and know i had some good times on it rather than being careful all the time.
if it goes it goes, it can be sorted, thanks for the info
