New guy to Buckets

Ok 65.5 bore and 49.5 stroke is 166cc. Are you saying I can run that combo?

No. That is an amazing example of how miss-understandings can begin.

I didn't want to but the exact number on the overbore allowance because I couldn't be bothered looking it up.
I know it's around 156 or 158 but you should have a look on the MNZ website (Chapter 24 but also see chapter 10) and have a good look over them yourself rather than relying on others interpretation.

That looks a bit blunt as I re-read it for spelling, it's not meant to be rude but it is straight-up.

I did all the number crunching a week ago and I interpreted it as 156.8(memory only) so the xl125 crank and a xl185 barrel which is the same as a xr200 barrel just with smaller bore at 63mm is 154cc and below the rebore limit. Fish seems to think if i have 154cc ill be ok on the rebore rule.
if its 65.5bore ill get it pressed out and a 185bore pressed in and 185 piston rather than get a second hand 185 that may need rebored to use.

154 sounds sweet on rebore to me. Fantastic.

Been looking on and of for 2years lol. Got uber keen again a month ago after watching more racing at Kaitoke.
I keep looking at the barrel and think it may be a pre 80 175 as its very round to be a xl185s or xr200.

Pre 80 is back to XL175 innit?

If so it'd be a 2 valve job.

I wont have the bike for a we while. Can I PM you once I know what I have motor wise. The seller was the father of the owner and his son is living overseas. I also think he wasnt the builder of the bike as they dont seem to have many details. Its possible since the bike was already being raced that its a 185 sleeve as the barrel for xr200 and xl185 is the same. I dont think it would be a 175 but the barrel doesnt look xr200 from the photo.

I'd say just turn up and race the thing, I doubt anyone will complain, if they do, offer to drop any points you manage to gather up. Start in B grade and even less chance of any drama

Yeah ill turn up for a ride but kick might have a xl185 one size overbore piston which would calculate at 155.35 cc and there is a full gasket set kit for $21.00 plus $5 freight so ill grab those and .25mm overbore it if its 185bore or press in a new bore and oversize .25mm on that.

PS sorted Kickaha is going to send a 63.25 piston so if its not legit it soon will be.

More questions sorry.

This tank with a one way breather tube and make a false fibre shell from the original tank sound a good idea. The original tank looks like a leaker and even if it doesnt will be full of rust. The small tank I could move forward and higher for gravity drop into carb as the carb seems to sit high up and where the base of most tanks are.

Sure. My experience with both is over 30 years old but fire away.

That is exactly what I have done with my bike and my old man's bike. I just used the original tank as a male mold and covered it with a few coats of mold release wax and some PVA (releasing agent not the glue). Put 2 thin layers on cloth on so it was nice and flexible to get off the mold (tank) and reinforced it from the inside afterwards.

Try and get one of the plain black tanks rather than the ones with the silly carbon vinyl on it. It is not fuel resistant so the bits that are folded into the inside peel off and fall in your fuel.

Yeah good point same trader has the plain ones for $20 plus freight. There is a cbr600 full race fairing kit with tail on tard me for 150 which im tempted to get for the tank shell and tail then sell the balance.

too wide. you want to be able to move, no point having a small bike & restricting yourself, kart tracks are twisty. Even if you find a naff old tank to cut the bottom out of as a shell.

Oh hold on it has one. cut it down as small as & use it as a cover. Obviously be aware of the explosion danger, open it up in a tub of water or something.

Hmmm, I recall a SHIT laod of bucket racers whinging about the 155cc motard thing, as it "started at 155cc, and was not bored out to it after wear and tear".


Could some cunt enlighten me, as to how I know which side of the double fuckin standard is the right side?

[hmurphy]

Sure. If you're on a 200cc bucket and coming last then no one care. If you're on a 159cc bucket and you're beating people then fuck off. Nah I don't know the rules. I'm probably breaking most of them.
