Thanks for the reply.
When you filled with coolant and did the side-to-side tipping, are you filling into the radiator only, not the expansion tank;
and also are capping the radiator when doing the side-to-side tipping and rechecking fluid level after the tips?

No. No oil in coolant or coolant in oil. And no coolant smoke out the tail pipe.
I took the radiator in to the radiator shop for them to give it the treatment.
I'll look into the head if the radiator clean out doesn't do the fix.

Were you finding coolant in the oil?

Thank you for your reply.
I can understand a leak causing the overheating, but why is the overflow tank "overfilling" and draining, or are you suggesting that the cooling system is over filled?

My 2006 GV250 with 28K miles is overheating.
What I am finding is that I am loosing coolant.
All is well until about 40 minutes and 25 or so miles.

What I am finding is that the coolant reservoir tank (the plastic one accessible from the front cover), is over filling and coolant is being dumped out via the overflow tube. When I start out I have it filled to the mid point as viewed through the gap in the dash area when I end the ride overheating, the reservoir tank is full.

I have been trying to fix this for a bit of time now and can' make any sense of it.
I have checked hoses and replaced hose clamps making sure there are no leaks.
I tested the radiator caps pressure and it is good. Couldn't test the systems pressure as the testers cap wouldn't fully lock on.
Tested the thermostat and it is good. The thermo switch seemed questionable (fan worked sometimes, but when really hot it wouldn't come on.) It also measured as a closed switch when fan was on but other times wouldn't close when engine was into four and 5 segments on the dash. I took it out and measured it in boiling water and it measured in the meg ohms. I ended up bypassing it with a switch and run the fan manually.

Also, I can let the machine run at idle for an hour and and it doesn't overheat (that was when I knew the fan sensor was working properly.)

Any help/ideas?

I usually get 12 to 18 months out of a battery.
Just recently my charging system went bad and it ended up being the stator had gone bad.
It was approximately 18,000 miles.

I replace my gear oil every or every other engine oil change, which is every 1000, or 1500 miles depending on how the timing falls and availability to do so. I know it doesn't need it that often but it's an easy job to do.

When I had my scooter in at about 15,000 miles, to replace the rear tire, I asked the service guy to check the belt and brakes. He said all were in good shape.

Thanks for the reply.
I planned on replacing with the 18g ones as you suggested here and in another thread.
I need to install a new belt, so figured now is the time.

Grandvista 250 / Roller weights question.
« on: August 04, 2014, 08:49:47 PM »
Sorry if this is a redundant question, but I did a search first and didn't see it anywhere.

When I go to buy roller weights, for example, http://www.partsforscooters.com/169-219_Dr_Pulley_Roller_Weights,
am I getting a qty. of six (6) weights in the purchase of qty. one (1) for $38.99 or one (1) weight, meaning I need to order qty (6) for total of $38.99 x 6 = ~$230.00? The picture shows six weights but no where does it say getting six.

Thanks

Edit: And are the sliding weights drop in replacements for the original roller weights, or do I also have to buy a new variator (holder) as well?
