Yeah. That might've been the problem in the first place and the problem I had after cleaning the valves. Hopefully Motomart should sort it all out

Got the RG back from Motomart. They de-coked the exhaust, fixed the powervalves (one was stuck open) and sorted out the jetting.

I haven't taken a proper ride on it yet, just rode it home. It does have a lot more power, it has a much smoother power delivery, it reaches redline faster and I don't need to shift down a few times before it gets moving. It does seem to sound tinnier now and it vibrates a lot more though. I could feel my nails rattling off.

It's meant to be running as good as it can now. The CBR was faster

The cbr has a few more horses than the RG.

Yeah, seems a bit unfair that they compete against the 150s in streetstock. I'm not a very good rider but the CBR gave me the advantage to fly ahead of some very good riders

It also has quite a few more kilo's to haul.

But it has an overall better power to weight ratio, I'm willing to bet.

Not to mention a far better spread of power. If you're lazy about keeping the revs up, expect to be blitzed by a 4/ 250.

I am just about to enter the wonderful world of RG150 ownership and I was wondering if there was any way of knowing if the power valves are functioning properly without taking the engine to bits?

I recently rode one I really liked but when I got to about 10000rpm in 2nd it was pissing and farting and didnt want to go any further? It had only just warmed up (on a coldish night), could this be the problem, or does it sound liek an expensive PV prob?

Any advice would be much apprecited.

Thanks for the offer mate, I will probably take you up on it when I bring it up to Aux. Found out my TR110 is gonna take a bit longer to get fixed so I will have to wait until next week to get the RG150. Damn parts coming from Japan taking so long!

Well it may not have warmed up yet. You should give it about 5 minutes standing still on idle before riding it. RGs run too cool over here as well since they were designed to run in Indonesia. Taping up a 3rd of the radiator will make the bike run warmer

Generally if theres a problem with the powervalves alone the engine will be smooth up to 8000rpm then the power will die and the engine will sound like its struggling, and when it eventually rises to 9000rpm it'll carry on screaming towards redline

I'm still no expert though, this is just some info I've picked up over the months I've owned my RG. By the way, I like the RG so much I'm buying another! Jamezo is selling me his wrecked one

The money will help him get an RGV

sweet news mate

the first step to being like me is owning the same number of bikes

**JeremyW** · 19th September 2006, 07:25

Thanks for the advice. I am quite looking forward to getting my mits on one

Jeremy- if you're referring to my bike you took for a ride last weekend then it would have still been cold when you tried revving the nuts off it. Hence the nasty spluttering sound!
