Moto has the weather or humidity changed lately to coincide with your pipe change?

the single most catasphrophic 2T issue is a bottom end failure, most of the time caused by a poor maintenance schedule or poor lubrication, or less common poor engine rebuilding technique.

Lean out usually happens at sustained high revs after the jetting has been incorrectly guauged, holes in piston is simple and pure heat due to mostly not enough fuel to cool the chamber, but usually one must ignore many symptoms to get to this stae

Its not long ago that two strokes won all the major long distance races where they got held wide open for extended periods ie: Finke, Hattah, Baja etc to name a few. It wont matter a big rats rectum if it runs 50 to 1 or 25 to 1 if its not jetted correctly. If its jetted to lean it wont matter what oil mixture you run. If its sucking air between the carburettor and the cylinder head again wont matter what mixture you run.

If it is jetted to hold it wide open you can hold it wide open its simple and fact.

herein lays the answer, especially since they should changed the main rather than lifted the needle, sure they weren’t butchers masquerading as mechanics?

Sorry XY I hate charletans that take advantage of my fellow man this way.

thanks TB, i understand that it’s his opinion,

but when you get two or more of the same opinion, from unrelated people that have never met, you have to think there may be something to it.

Mr B please correct me but the RZ’s are oil injected/self mixing, therefore oiling the needed amount even when you are coasting thin the throttle off/closed.

the same with my Bro’s honda CRM 250 AR, oil injected, he has had 10 000+kms of trouble free riding
8 000+ after he put the Mugen power up kit on it. he only just put a new piston and rings in it.

he dose not baby his bike nor dose he thrash it.

and the blokes at Boltons told me that mixing the fuel richer like you Mr B , that the bike would have done the same anyway. as it would be too “thick” for want of a better word, it would not draw enough fuel through and thus run lean anyway. = failure.

but now through some of your informative posts that if it had have been jetted appropriately for the richer mix i may still have the bike???

as for a young XY :dry: naive,uneducated, ill informed? Most definitely yes!

Young XY you are indeed correct on the RZs et al:, but topend seizure is rarely from lack of oil, it is more from hotspots, as for Boltons telling you the mixture would be too “thick” I’m afraid it appears from propogating that “idea” they suffer from that condition themselves.

An increase from 50:1 to 25:1 is a mere 2% of liquid by volume, sorry their explanantion would have had me ROTFL, and pointing out that their IQ was similar to the octane rating of standard petrol, besides that’s why they make alternative jetting.

Not sure that I agree about not riding 2T on the blacktop, I had RZ350 did tens of thousands of Kays on the road, without engine dramas, my RZ500s and rz640s the same never a siezure due to roadriding, only tuning stupidity ( :blush: ), and both my KTM300 and YZ250 do blacktop without a drama, although on the trailbikes I run at anywhere between 25-32;1 fuel oil ratio and on long downhill sections “blip” the throttle or hit the killswitch and fullthrottle at same time, never had an issue like you’re describing young XY.

Maybe someone shoulda given a few hints when selling you the smoker.

I also inrensely dislike loose sand MX tracks, as TB said they suk bigtime

Very apt for you too Moto, as the original Toranas were rebadged Vauxhal Vivas.

Holey shit!! I just googled my name and there is a dude in America with the same name as me, that killed his wife and her name is the same as my wife!!
And he did it in a town in North Carolina that I have been to!!

That is creepy. :blink:

1 in 100 men are sociopathic, in America 50 people a day are murder victims, and the FBI estimates there are 500 serial killers currently operating in the USA, looking at those Stats Mick I’d be worried if one of you hadn’t killed someone.

there’s actually articles on how not to be a murder victim.

again good deal Mr Rat, but too fast and probably too small (not engine but overall size)

I’ll tell him

Top buy TB, but probably too small in the height dept for this lad, if it was a senior adv be the ticket though.

Should move like ice cream at Bondi at that price tho’

[Bruce CurtisMember]

Mick not sure that a bargain is warranted (not strapped for a quid as it were), I indicated $1500 would see a beauty land at his door.

But I agree with you.
