Well,weather turned good and took both the 309 and the 240 out today,they are very different rides,only thing in common is the forward kick!The 309 fits me far better,feels more natural to ride. Of course the disc brakes and mono are great,but the main difference is the more forward weight bias plus the heavy flywheel effect. The 240 lifts the front without much input and the engine is snappier,but it may be geared lower(will check the sprockets when I clean 'em up tomorrow) The 309 needs a concentrated effort to pop up the front. Clutch action on the 309 in nice and light,I can use just one finger to ease it in and out. I was able to clean sections in my practice area that I was struggling on the twinshock. I will be competing on the 240 in the coming year and I'll prepare the 309 for a go at the senior class next year.This gives me a direction for tuning my 240 as it's the only trials bike I have ever ridden and don't really know what is best all on my own.
The 240 responds smoother down low(ain't nothin' wrong with piston port engines!) but It does have an OKO,both were running on last years fuel,no doubt stale as hell so I won't judge any tuning until I dump the old stuff into my Jeep and buy them something fresh(today was a clear the trails day,not a full playride day)
Yes,the 309 does have alot of piston rattle,Don't know what is considered normal for these,just what I've read on the net,she'll get a new one before riding her much more,I have no doubt she'll always be noisier than a 240 but if I put a new piston in her I'll have peace of mind.
