LRP ZR .30 X competition (truggy) - Pull start conversion.

[Londoner]

Hi all,

I have an LRP Z.30R pull start on its way, id love to have bought the x competition version for the extra revs and bit of extra HP etc but its a bump start engine so its ruled out for our savages.

However, iv been doing some googling and just generally looking up info on the engine i bought and found this, i know its the same info as on the LRP site but i didnt think to compare part numbers between the two on their site and this has part numbers for both engines on one page together with a list of shared parts between the two http://aedownloads.com/press/in_022309_lrpengines.pdf

Both the engines share the same crank, crank case, con rod, burn room, bearings, wrist pin, o rings and hardware etc with the only differences being the cooling head (probably just different writing on the head) carb, piston, sleeve and backplate, now could i buy the X competition version and simply change the backplate from my pullstart version then add the pullstart itself and voila a higher revving slightly more powerfull LRP 30 X competition/pull start engine for our savages, or am i missing something here?

From what i can see this is very do-able, what you think?

Thanks for reading.

I was told they have the same crank

If that is true its back plate 1 way pull start done

I think thats all it is a matter of, according to those parts lists in my link are the same crank, crank case and all internals barring the carb, piston and sleeve which has 7 ports as opposed to 5 on the pull start.

So, id assume then that it would also be possible to convert the pull start engine into X version by swapping over the piston sleeve and carb, as the burn rooms are the same part No i don't think that swapping the cooling head would make any difference, they look identical except one says X competition the other spec 2.

Though of course it would be easier and cheaper to buy the X version together with the pullstart backplate, one way and pullstarter.

yea its just more ports on the other sleeve. IDK if ebay chop shops are parting them out yet but look into it. You can get the parts cheap

 

[Londoner]

Yea dollar hobbies on ebay did have broken up .30 spec 2 engines for a while but not anymore, I'm sure there will be more chopshops doing them soon though.
