    cam chain idler gear options

    Ok, so the rubber idler gears tend to be an issue, in digging around, I found metal ones for the cl 350's ext available. and apparently the CT70 ones are interchangeable 9 or a least usable) but still rubber. does anybody have a line on metal, toothed idler gears for the groms? preferably on a proper bearing?

    or does any body know if CL350 ones will work? found these on ebay, look promising.

    Its on a bronze bushing, right? (looks like it, at least) I dont see any issue using that, as the CB350 reved higher than the grom does.
    Although, at 115$ for the pair, i wouldnt be running out to buy them just as a test.

    Id personally prefer to stay in the nylon department, as it is self lubricating, but with oil right there, I could see the use of metal idlers.
    I think nd4spd said that the CRF70 used nylon/delrin/some other plastic rollers, and ive been meaning to get some, when mine go bad. I suspect one has, because after my rebuild, running at 8k+ was quieter than before, but now, the noise is back again. (strangely enough, it quiets down after 10k or so)

    nope the 350 ones are on a needle bearing. nylon is not self lubricating BTW, unless its designated as such. heat and chemicals break down the rubber wheels, the added tension just makes it worse.

    dont remember ever seeing a crf70 using a nylon / non rubber rollers. I think i was referencing the fact they (crf50/70) use a very similar cam chain tensioner setup, and that they make manual cam chain tensioners for them that could possibly be used for the grom setup.

    My valve train is NOISY, but thats due to the cam, finbro springs, and i think most of all, the nylon button (bolt) that floats on the top of the tensioner rod, it all kinds clacks together at idle, but when running its fine.

    FinBro just released an upgraded cam chain roller. Unsure of it's composition (looks like nylon), but I imagine it is likely a beefier OEM sourced part

    Needle bearings.. Now we're talking! The Finbro one is an improvement but it's still lacking real bearings for those that spin high rpms a lot

    Maybe a handy dandy machinist type fellow with a nice lathe could turn a high durometer skateboard wheel to fit with some abec 7's or something?
