For the love of a tractor engine: The life and times of the 18R-G

[o_man_ra23]

Without the stroker, yeah you would have pretty low compression. My 8.3:1's have a noticeable rise in them. Flat tops would possibly work, but again, you are running rather low compression on that.

I'm not going for a turbo... just keeping it simple... but that itself may pose a challange.

Does anyone make oversized high compression pistons for these any more?

[JustenGT8]

flat tops give approx 7.5:1 with standard bore from memory.....the 2.4 stroker also has flat tops but with increased capacity it give more like 9.5:1

I'm not sure whether Toysport use the Kameari ones...

They used to have prices on the web, but don't anymore. Send them an email.

LC Engineering have pistons in stock for the 20R and 22R without valve reliefs. What are the most critical dimensions I need to be looking for to compare them with the 18R? Obviously bore is going to be the big one, what about gudgeon to crown height? and how will 10:1 for a 20R translate to an 18R? much the same?

I'm almost finished rebuilding my Step Sons RG and I have used standard 18R pistons with factory .040" O/S bore(was originally 9.7 comp).Runs 210 head with 40mm Solexs,Extractors and what seems to be a balanced crank.I have built other RG'S with 18R pistons and never really found that there was a problem.
In its original form before the rebuild which was caused from a loose gudgeon pin and a skirt missing off one piston it was performing very well reving freely all the way to 7500rpm.
So after I finish the rebuild I will keep ya's posted on what it performs like.
Cheers Brett.

my rg is simular to yours brett except it is .060" O/S. if you can get the solexs runnng nice it should be a good performer.

cheers

never herd of such a thing

Possibly a dumb question....but is an 18rc and 18rg clutch configuration the same or interchangable??

[RA35GT]

They are interchangeable.

[LT1986]

sexcellent....thanks...I need to get rid of my set up and its near new....taking up too much room..anyone interested? Non genuine Daikin unit...done 5000km of light duty on it. Im putting the box up for auction on Ebay since it has a 13b adaptor on it

ill chuck it up in the for sale area for future prosperity

(btw, sorry for peddling crap in the wrong forum....i can just see a 'why did you ask?' coming up)

I wouldn't say that to River, if he tells the 88, she might get upset

Hi,

Nahh, The 88 is cool. Like me, she understands there are the talented few who can tune Solex and have them singing sweetly, and the vast majority who can't.

what's so tricky about solex's? We had Dana's old hybrid running a 4.5kg flywheel and it idled (and ran) as smooth as silk with 40mm Solexs..

[Roscos]

All carby's can run smoothly it is just the clowns who tune them that make them run better. Some are better than others.
