That`s a bit of a schoolboy error Jazzbutcher
To help you work out how much gap you need; I have 10 weight oil in my forks with no change in volume from factory, 12mm of (bike ) Sag, standard springs, and my forks have never compressed any less than 19mm away from the bottom casting.(and that was with the front wheel locked up and the bike standing on its nose.) You can tell from the state of my swing arm how that ended up. Whats important in this situation is not the oil weight or damping settings, but spring rate, preload,and volume of oil. These three will determine how far the fork will eventually compress and also the gap you will need above the mudguard/tyre.
Again I hope this helps. Regards Alastair.
Yeah, schoolboy error indeed, I only checked that it missed the mudguard.
I now know exactly how far the forks compress heh heh, so unfortunately I think the fan is too big (deep) to successfully fit in that space, shame as well as I found some brand new very similar SPAL ones pretty cheap. See above.
Looking for smaller one/s that I can fit elsewhere maybe a computer server fan as they're pretty good at air volume throughput & are a lot smaller. It's the heat that's the problem as most are plastic & working temps up to 70c.
Or I can as you suggested, pull air through the frame with one of the above fans, which means pulling warm air through the radiator fans unfortunately. At least that will speed the process up I guess.
We'll see, I'm not downhearted or anything as the process works ok, just a little pissed that I missed such a seemingly obvious problem.
Ah well, Thanks for the info. All the best Paul.
