Hi Guys,

Any of you Aussies out there looking for a Ryobi conversion ready to bolt in or conversion kits and /or individual parts to do your own conversion without having to source from the States send me a PM for a pricelist. I am doing Ryobi's mainly but can do Homelite or convert your engine (any brand generally). I have done a number of chainsaw conversions for myself so if you have a spare one sitting around why not get some use out of it.
My Ryobi 31cc conversions have a new ring and bearings. They turn a 18x8 two blade or 16x10 three blade prop at 7400 to 7600 rpm. I also offer electronic ignition version as well which tachs at around 8000 rpm.

Here's some pics. Enjoy.

cheers Tim

G'Day Tim, I realise your post goes back a bit but I was just wondering if you are still doing these conversions or still offering parts to do the job. I was given a near new Ryobi brush cutter and recently found out they make a great conversion to an RC engine.

Regards

I've used Tims parts on a Homelite and they are great. The workmanship is first class.

I have to agree I visited Tim over the weekend and picked up a couple of Kits for conversion.... A great help and top quality kit too....

Thanks again Tim

Mick

Tim sent me a price list and I was impressed with the prices ,especially the muffler.
I'll be getting all the bits from Tim as soon as I find me a 31cc. I found out the one I have is a 28cc . I'd rather the 31cc for that little bit more grunt.
My Dads neighbour is a Talon dealer who repairs and sells factory seconds. He also deals with other brands so he might be able to help me out. I'll have to speak to him and see what he can do.

Not sure what plane I'll put it all into yet, when I get the motor sorted I'll do some mods and tests to see what it can do.
That will give me a good idea of what I can put it into.
What planes are you guys flying with your Ryobi?

Don't forget to get a bigger carb, the standard one supplied with the 31cc will lean out at high revs and cook the motor.

As for your Talon contact, can you confirm if the Talon engines are the same as Homelite. A quick inspection shows them to be visually identical.

I hadn't even thought of a Homelite mainly because I have this Ryobi 28cc sitting here. But now that you mention it ,if that's the case with them being the same then I could be onto a good thing.
I'll find out what I can and post it hear A.S.A.P.

OK I've spoken to the Talon dealer I know and he told me although Talon and Homelite are very similar they are not the same. Some parts are interchangeable with the mentioned motors but not sure if a Homelite conversion kit would fit the Talon.

Interesting. Unfortunately I have more engines than I can realistically use at the moment and won't be buying a Talon just to compare parts.

Does your Talon dealer know anything about the GMC engines, they are also VERY similar to the Homelites?

The Ryobis, based on my limited exposure to them, then to be more powerful than the Homelite engines.

As an aside, I found the 30cc Homelite to be less powerful (rpm-wise) than the 25cc simply because the exhaust porting differs so much. More testing and measuring required, if/when I get time to do it.

He does repairs on all brands but he doesn't stock any of the GMC models.
One thing though, he told me that the 25cc homelite on the bench produces around the same RPM as the current model ryobi
31cc. But the ryobi has more room for improvement and he has tweaked a few and got around 9500 rpm mainly buy changing the muffler and carb. I asked him if it was safe to run a ryobi at that rpm and he said the one he tweaked is his own that he uses at home and is still running strong. He said the main issue with running at this rpm for extended time is heat build up which could cause damage to the bore. His is used as intended (As a Brush cutter) but don't know what sort of results we would get with an 18x8 prop. He said it's best kept at around 7500rpm according to manufacturer recommendations.

I've noticed myself the 25 and 30cc Homelite have different porting, enough that the 30cc with an otherwise identical configuration revs lower...

As for Homelite vs Ryobi I have compared both as equally as they can be. Same carb, same muffler, same prop adaptor, same prop.

Homelite 25cc will do 8000rpm
Ryobi 31cc will do almost 9000rpm

Note the Homelites generally use a 16x8 and the Ryobis a 18x8. In this case both engines used a 16x8 MAS.

Another common belief is that the Ryobis should not be run at high revs for extended periods, 8000-8500 being the reported redline. Looking at the rivetted stamped plate construction of the crank counterweight and connecting rod I would believe this.

Where can I find the convertion kit for my Ryobi 31cc?
