god damned bolts *part 2* :D

ok, well just finding out the little shifty things that the dealer has done repairing this ninja... and its annpoying, he has used weird un-matching and one bent bolts for the 2 tank bolts near the airbox, i pulled them to get to the airbox and clean it out... now they wont go back in, i its being substituted with about 10 zip ties through each hole

but onto better matters, does anyone know the dimensions of the original 2 tanks bolts on the kwaka? im thinking of just going to the hardware and sourcing some new bolts.

EDIT! after searching through the hardware i found out they were M6 bolts not the 4 listed on them

what model gpx???

i dont have any spare down here otherwise id bring them up.
i could always be nice and go and check on my bike, but well yeh there is a thing called a manual and it should tell you..

hah no, believe it or not, but i actually checked the manual


i actually looked at the bolt and its got 4 stamped on its head, so i checked up metric 4 bolts, and it doesnt match the specs, it seems to be more of an M5 or 10 bolt... but meh, ill go take it to the hardware tomorrow and have a looksee...

If it's a GPx250R (it looks like my old 2000 model) try here:

>> 25mm long according to the diagram.

Note: Be careful, metric bolts come in three common pitches, some are finer threaded than others.

its ok i checked every measurement except for the pitch of the threads which i just based on eye then tested...

The number on the head of the bolt is tensile strength and has nothing to do with the actual size of the bolt but is still important as you should not replace a (4) with a (12) or viseaversa ans the bolt can break
Generally 10 mm head or socket size is 6mm thread size
12mm head size is 8mm thread
14mm head size is 10mm thread
all jap bike follow ISO standards for bolt and thread sizes
hope this helps

ISO? whats that... imperial?

but anyways, the bolt is exactly the same as the one before, just shiney... and the tensile strength is different, but considering where it is, i doubt it will make much difference at the moment and its a helluva lot better than zip ties! *2 dollar zip ties from the reject shop i might add!*
btw the tensile strength is 8.8... whats the range of numbers relavent too? higher number is stronger or weaker?

The higher the number printed on the head of the bolt the stronger it is. ISO is the international standards organisation which consults with manufacturers and sets standards to be followed
"12mm head size is 8mm thread 14mm head size is 10mm thread"
is a basic standard
Imperial is actually a British Standard size sometimes referred to as a witworth thread being the most common

Yeah being a mechanic i had to deal with all this shit.
As mentioned above the number on the head of the bolt is the tensile strength,not the size.We used to have american,which was unf and unc threads(united national fine and couse thread) and then the british who had whitworth bsf and bsc(british std fine and course thread)although the threads are pretty similar up to about 3/8" i think it was.Then some bright spark says why dont we conform all of this and make metric.Good in theory except in some cases the euro and jap metric differed from the australian metric(different pitched threads again),so really it was all a waist of time. Also you need three types of spanners for each type,a/f american,whitworth british and metric.Nuthing is ever easy in this world!
