There are some hardened Genesis pinions being produced privately by a guy on ebay. I mailed him and he says if enough people want FunFactor steel pinions, he will do 14 tooth (1st gear) and 18 tooth (2nd gear) for $35 a pair, incl shipping.

I am running Genesis hardened steel spurs, 39 and 43 tooth (on cens optianal alloy 2 speed hubs), on my funfactor, and I am about to fit a .28 in it. Anyone with a big block, or thinking of fitting one, would be well advised to check out this setup.

Anyone else interested?

Do you have the part #'s for the "optional alloy two speed hubs" or a link to them?

Are 14/18 going to be the only options? That gearing is ok for the most part but for a shorter track or a grassy area, a 12/16 combo would be better.

Is this a UK only thing or are they willing to ship to the states also?

Glad to see you got your computer fixed and thanks for taking the time to find out I have been to busy lately to really do anything about it.

If the guy needs a bulk order to do the work, you can count me in. Sounds like a bargain, I have just bought another complete c/b which is my fifth so far!!

The guy selling/making the gears is based in Italy, for US$35 I believe he will sell u the pinions and ship them anywhere. He may have just meant to the US, but hey the UK is closer!

I asked for 14/18s Rolland as I reckon they will suit mine best with the .28. Other ratios should be possible, but again would require a bulk order. Im sure that if he put them on ebay he would get a good response, but we are just putting some feelers out to gauge interest.

I guess we could all come to a comprimise as to just what ratios we want, if enough people show interest - I only bash mine, so Im not too worried what we go for to be honest guys, I just gave him a number to get things rolling, so long as we stay within the boundaries of sensibility...

The alloy 1st gear hub is part number G84302-04 and the 2nd gear alloy hub is part number G84302-02. I got these numbers from cens page, www.cenracing.com - click on accessories, then 2 speed.

Thanks for the info. I am interested in the 14/18 combo. That size should also work well with the OS .18 motor even with maxx size tires if they are kept relatively small.
That .28 motor should be able to handle a 17 or 18 first gear. I have seen a Mammoth at the track with a 16 tooth first gear pinion and it had no problems. The gearing on the Mammoth is 13/47 in the diffs and 60/65 spurs and 11 plus pounds in weight so, with the 38/42's a larger first gear pinion could be used.

just be carefull rolland with the 14/18 and tmaxx wheels - it has a veracious appetite for standard cen clutches! and thats with a 47t spur. i had 2nd locked out... 1st was scary enough when the clutch actually grabbed - which was rare and short lived - ie 3-4 tanks per clutch!!!

u may be able to find lighter tyres that would help tho - but to give u an idea of the weight issue:
my imex romulins with ofna brick pins incl foams weigh in at 300g each, whereas my cen rally wheels and shumacher cut pins weigh 75g each!! kinda explains the speed of my rally... so that works out as 4 rally wheels n tyres are the same as just 1 tmaxx wheel n tyre!

apols, i have no cen mt wheels to weigh...

Thanks for the advice.
Stock MT2 wheel is 237 grams.
I haven't switched over to maxx wheels yet, I still haven't decided how I am going to do it. When I do I will have to re-gear again.
If I start to have problems with the clutch I have an XTM sliding clutch and flywheel that I know will hold up. I also have an Ofna aluminum 3 shoe setup that I can use but it will be hard on the bells.

anyone else?

i gotta give this guy a number sooner or later!
