Thermo bob
Hi all, I live in the uk and have read that it is a good idea to fit one of these thermo bob units, have you had any experience of fitting one ? Also if it is a good idea, where can I buy one or if anyone has got a kit for sale

I fitted one to my KLX250, no big deal, easy to do. I did it because the information made total sense, uniform temperatures around the cylinder versus the stock set up.
I'd recommend you see if you can get another KLR650 or KLX250 rider to go in with you if you have to buy new. Spread the shipping over a couple of units. I do it with the cam chain tensioners I sell. I can fit more than one in a box and only charge the rate it is for the box, so two tensioners spreads the charge over the two, three over three, up to five. That's what fits.

It will not add to cooling capacity in any way.
It's main benefit is to get coolant up to operating temperature for those that live in cold climates.

Pro Cycle also sells a thermostat bypass system that does the same thing

The Thermo Bob will help bring the bike up to temperature and keep it within a narrow temperature range.

The ability to pump some of the water around all the time improves the uniformity of the coolant around the cylinder, which will make the cylinder temp more consistent - aka no cylinder taper due to non-uniform thermal expansion.
Of course when the thermostat is wide open the thermobob does nothing, fluid flow is open to go.

Hi all, thanks for the replies, I just ordered one from the link supplied, thank you, The Thermo Bob came about from me looking at the over heating problem I had, bearing in mind I have only had the bike a week didn't realize there was no cooling fan, seems ok until in traffic and the needle heads up near the red but comes back down when moving, I have just purchased a fan off ebay so should have it installed next week.
