gee wizzz
Riffer has a lil RG150 in his gargre. Battery is as flat as a pancake.
In neutral it will rev right up no issues.
In gear aparently it wont rev into the power band.
OTHER than the fact that he's used to riding a heap bigger 4 stroke bike so possibly aint wringing it out can you think of any other reason it wont rev.

Probabaly the Power valves. They are a unfortnate issue on the RG's. The centre's are probabaly buggered, repairable tho.
Is the bike pulling up to about 10-11 at a push, but not much more.
on the up
Yeah, that just about sums it up exactly.
Trust me, I know how to ring a bike out LOL.
Its not revving freely.
And I to my motorcycle parked like the soul of the junkyard. Restored, a bicycle fleshed with power, and tore off. Up Highway 106 continually drunk on the wind in my mouth. Wringing the handlebar for speed, wild to be wreckage forever.

Double shot!!
Dunno much about powervalves and stuff, but being a 2 stroke, the very first thing I would do is put some fresh gas and a new spark plug in it, and see what it had to say for itself.

I can come take a look if you want. Im no expert but have had many RG's apart, and back together. Most likely will be the powervalves.Originally Posted by riffer
Definetely sounds like the power valves, what luckily is a easy fix most of the time. But requires a good welder/machinst. Not worth buying new ones as they are 400$ or something stuipd.
Pete Jones does swaps where you swap buggered ones for new ones for X amount, way cheaper than new ones.
Powervalves make a massive difference, like over 50% more power between closed and open. Must inspect them every 5000km because they are a major weakness on the RG150's

gee wizzz
dont pull it appart unless its goin back together before sunday.

Going away. I take it your coming to get it/whatever. Might as well leave it till it gets to you then. Its a minimal thing to pull apart. Just take the radiator off and then the powervalve cover and ta da.
gee wizzz
Sorry dude I was tired last night--patroling the property for bike theives
ANYHOO Clivorus is picking the bike up monday I think and my lad is gonna be riding it in the carpark/pits at taupo track. SoI was just worried it wouldnt be back together in time

If you going to take it on the track, id strongly reconmend getting the power valves fixed. Its a realtively easy fix and you only have to take off one cover.
Bike should still be rideable although a little bit slower than it should be, but still be able to 100+
No worries. Hopefully i'll see you kid out there this year

So what exactly is involved in fixing it ?If you going to take it on the track, id strongly reconmend getting the power valves fixed. Its a realtively easy fix and you only have to take off one cover.

Hey mate ill send you the RG150 manual. Whats your email?
Well without seeing the powervalves i can't say, but the most probabale thing is that the centres of the powervalves have been flogged out.
However theres other things what can go wrong, ultimately they can fall down the cylinder and fuck the whole engine.
The actuator could be buggered as well and a number of other things.
If they are flogged out its a matter of welding the flogged part up, however they are hardened steel so you need a very good tig welder. A couple years ago i got Luke Jamesons one's fixed at my dads work, to a very good standard. (My dad owns a engineering company).
You can make a number of things up for em.
I'll try find you a picture to show you what im talking about.
If its his first time out there i wouldn't worry about it mate

it will only take about 10min to get to them... tops...
it is not a big job, but it NEEDS to be done, or you will be up for a new piston.... etc..
but i would REPLACE the batery first!
(after new plug and fuel )
make sure you increase the gear box oil by 100mls!!!!
and make sure when you ride/race it that 13k is seen on rev counter often... will keep things clear...
it in ANY doubt, PM Oyster, he has ALL the knowledge on these bikes
what a ride so far!!!!
on the up
Okay...
So far I have tried:
1. Recharge battery.
2. Replace petrol
3. Replace oily (but brand new) NGK BR7ES spark plug with new one
4. Cleaned out the carb
and the damned thing STILL won't rev over 11K.
I may have put you wrong before Tony - the bike is revving easier to 11K at idle than under load but it still won't go over those revs.
So it's looking like it's the powervalves. Is the actuator the box under the tank with electric leads going in and a cable coming out?
It's all back together again so no worries.
Hey - the back brakes are still a worry. That rear rotor will be lucky if it has 3mm thickness. It's so skinny the pistons don't stand a chance to retract so the pad is stuck against the rotor and the rotors getting a bit warm. You'll definitely have to get a new rotor.
And no - it ain't my shitty workmanship. Those pistons are polished to within an inch of their lives and the seals checked and rubberlubed before reassembly AND the pad edges and slides lightly lubed.
And I to my motorcycle parked like the soul of the junkyard. Restored, a bicycle fleshed with power, and tore off. Up Highway 106 continually drunk on the wind in my mouth. Wringing the handlebar for speed, wild to be wreckage forever.

is early on the brakes
I've had mine apart enough times now that I can have the seats,tank fairing muffler and cylinder head off within 15 minutes. Theres not alot to the set up. just need the right tools to repair the damage thats there.
As has been mentioned previously Oyster is a good man to deal with and turns things around like you needed them yesterday.
gee wizzz
thanks guys. I think Im actually happy it wont pull past 11k . He's NEVER ridden a road type bike so thattll keep him from being an eejut
That said the last owner only used the bike as a commutter so I wouldnt be suprised if it aint real gummed up in there
