Hi,
I'm hoping some of you experienced guys can give me a hand with a few Lazer questions please seeing as I've just got hold of one. It's what is at least predominantly a ZX-R but not convinced it is totally ZX-R.
1. Bit confused on the layshaft as it has the little one-way unit on the opposite side to the spur and have read about this being replaced to get permanent 4wd but can't find a reference to how that's done.
2. Rear UJ's are worn out (fronts are okay). It looks like the Optima re-re might fit and then it can take the screwed on hex - or is there better option?
3. What exactly is the advantage of the blue Pureten steering? It looks more solid, but is that it? Looks like they're hard to find too...
4. Might fit the ZX-S shell as I prefer the look of it, but can anyone confirm if on the Kamtec version the undertray kicks up at the edges? i.e. the bodyshell side pods don't sit as low as the chassis (like the Optima Mid shells)
Thanks for any help.
