685 kit advice: break-in and mods

[Marc]

Hey Ken is that a technical term "bam bam"? hehe Have a good one!

No thermostat on your Vette means no bam-bam temperature cycles. It just warms up slowly and steadily. As said below Wattman's engineering is sound. Ken

That s why your expensive car has the equivalent of t-bob. The KLR cooling system design was probably borrowed from an offroad bike which is ok for most riders who will probably never hit 20k miles on their klr650. > >Not shilling for wattman but I believe his engineering is sound. > > >From:DSN_KLR650@yahoogroups.com [mailto:DSN_KLR650@yahoogroups.com] On Behalf Of Marc >Sent: Thursday, September 29, 2011 12:44 PM >To: kaykuri; DSN_KLR650@yahoogroups.com >Subject: Re: [DSN_KLR650] 685 kit advice: break-in and mods > > >Well too bad about the issues (how many miles on your 08?) and congrats on the 685 (should be nice). > >I would follow their break in. >Side note- I babied my 08 (no 685) during break-in and changed oil/filter every 500 miles until their was no metal in the filter when opened up. (I always do this on every motor) and switched to a 16 front sprocket to keep rpms under 5000 (I noticed oil use when over 5K) I hope to 685 mine when needed. So far no oil usage, but I only have 10K on the motor. > >Not a big fan of the Thermo-bob. Don't see the need for it and it's another point of failure.

While it was open, I decided to go ahead and have the Schnitz 685 kit installed, mostly in the hopes of stemming the rather alarming rate of oil evaporation I had been experiencing (and which likely contributed to the unfortunate opportunity). > >Anyhoo... the fixes and mods should be complete any day now, and I would like to ask the group for the consensus on a few topics: > >1) Break-in. The Schnitz documentation (http://www.schnitzracing.com/manuals/KLR%20685cc%20Kit-Instructions.doc) recommends a regimen of phased break-in with lots of engine breaking etc. Or do folks favor the "ride it like you stole it" method nowadays? > >2) Schnitz recommends the thermo-bob mod. I have followed the debate here and elsewhere on the relative merits of the mod, but I guess what I am wondering here is whether Schnitz's forged piston (as opposed to whatever the OEM piston is) changes the math at all. > >3) Schnitz also recommends the PCV valve mod. Not even sure what this one is, though I vaguely recall reading about it.
