The RG seized

[Kickaha]

You're kidding?

No I'm not good oil saves you money in the long run

Plus it's just as likely to fuck up with the nice stuff when you take Murphey's Law into account

In over 20 years of running two stokes (on and off ) and some a lot higher performance than a RG I haven't ever had a lubrication related seize using good oil

I've had a RG150 indicating 180kmh for reasonable amount of time with no problems, in fact it got thrashed for about a 200km round trip with no problems at all, so sitting on a indicated 140 for extended periods shouldn't be any problem at all

I was quite happy with the indicated 180km/h until F00T pulled up next to me, pointed at his speedo and signed out 1-5-0, then pulled a 2nd gear power wheelie into the distance

That's a bit odd... was the speedo saying 140? They get up to 180km/h @ 12,000RPM, but they are only doing 150km/h (very badly out speedo)... I had mine sitting at redline for about 10 minutes and I didn't have any problems with mine... what oil were you using? please don't say 'any old service station 2t oil'... I used to run mine on either R2 or TTS

I was running it at an indicated 170-175 but backed off waiting for the other lane to be empty so I could pass a car, then when I gunned it to pass the car it bogged down and the rear locked up. I would've been doing about 120-140

I do use cheaper stuff, Valvoline 'race' oil from Supercheap, $10 for the litre. Although for the last few months I was running it on some nicer Castrol semi-synthetic stuff that I got with the second RG (Jamezo gave me the lot since he didn't need it). Since then I had only used a litre and a half of the 'race' oil

On the great kiwibiker ride I had it at redline doing 150kph real speed and that was for a good hour. Didn't miss a beat and sounded great. I still do think it was a bottom end bearing finally dying, it does have 40,000kms on it

Yeah, still my budget didn't allow for much nicer stuff. I could've probably moved up to semi-synthetic at least

See above, I had run the RG for an extended amount of time before with no problem. That's why I gunned it this time thinking it was still capable of it (and to try keep up with my mates that have twice [and one guy with 4 times] the horsepower I had).

Something good has come out of this though. Being forced to take my bmx to school has made me loose weight

Yo Dan,

SImple advice on any engine Do not ring its neck out flat tack for 5 minutes you will have big bang,

And with a 4 stroke youl valve bounce it drop a valveinto the cylinder and fuck your piston barrels and heads

Sounds like you lean seized it....roll back to half throttle at lots revs, not much gas but still plenty of air flowing into there....NIP!!
Do'h tough luck man, better qual oil is ALWAYS a good idea....bet your getting sick of hear that thou huh?
Ah well, it was only a 150....roll bowl and arsehole them - they love it really!!

Dude, have you never watched and listened to a 600 race???
Rev limiters are there so they WON'T go above what a four-stroke engine can handle.
your more likely to knacker a 4-str by either; 1) revving it in neutral and flinging motor speed past rev limiter, throwing the valves into the pistons, or 2) backshifting and letting the clutch out so the back-torque spins the motor past what its cabable of - throwing valves into the pistons..... Thats why Ducati's Desmo system is so cool!! You don't have a spring that can only go so fast, you have a manual valve return.....revs are now limited by what the pistons and conrods can do

I hope i'm not talking too much shit - someone give me a bike to thrash!!
I'm just a dumb rider really...

This time was about 5 minutesof thrashing but I had previously gotten away with about half an hour at full throttle (on the KB ride). I didn't think much of it revving it this time

And that doesn't sound too good

Gosh, never even heard of that type of seizing

Yes I am getting a bit sick of it, I've already made my excuses and I'm sticking to them

At least I have a second engine, should still make it for one or two rounds in streetstock (more likely F3 due to the suspension upgrade)

Ooo, did some of those things accidentally on my CBR once. Tacho went straight past 20,000 and off the readings. Made a hell of a sound

When the RG is back running you can have a good ol' thrash on that. And I'm probably dumber than the lot of you guys on this site put together and then some

Off to catch the school bus!
