297 lb at 15.5 hp at moderately high compression so it is still light and flickable along with a bit too peppy for a new or inexperienced rider. Be sure to use Premium Grade Fuel in it since it has almost an 11:1 compression ratio.
On letting the Kids ride it the your correct in saying no. Let them make those newbie mistakes on some clunker with battle scars on it where another blemish won't show and it won't have the power to get up to Interstate Highway speeds.
Check out the bargains from Leather Up if you do not have riding gear to match the potential of the bike. A minor mishap on a 50 cc can be something to be embarrassed about however at over 150cc and closing in on 300 lbs injuries are more likely to require hospital attention if you don't some mid level gear.

On a 200 if your getting sunburned you really need to review your safety gear since there should not be much skin exposed to the sun except parts of your neck and maybe a half inch or so of your wrists if the cuffs of your gloves don't overlap the sleeves of your riding jacket.
Clear weather here topping out at about 80 degrees until a rainy Monday arrives

Is the head gasket that came with the head a bit thicker?
You may have better results with the head gasket that came with the head.

After 5,000 miles is this the first long ride or warm day? If you overfilled it X months ago one would expect to have seen evidence of that some time ago.
If the clutch was slipping you would be getting higher than normal revs and lower top speed.
How fast were you going?

Have you been out in the rain or ridden through standing water lately?
How hot was the gear case or rear brake?
If the brake was dragging or the clutch is starting to slip it could cause this type of issue but there should have been heat and the smell of cooked gear lube along with cooked clutch pads/brake shoes.

Do not over torque as that could pull the studs from the engine case or crack the head. Time to pull and measure to see if the head is reasonably flat and the machining for the dowels seems adequate then Copper Coat the head gasket and try again. I have had some replacement heads come in with gas inclusions in the castings making them porous so coolant or oil seeps right through the casting.
If the head gasket was creased or deformed in any way that is one other thing that could cause it to leak. What type of head gasket was it? My Piaggio uses a spring steel gasket while others use a laminated composite gasket.

Another beautiful riding day here in Florida. Almost rode past the office and kept on riding today. Tomorrow will be a day of Tropical rain squalls and wind so I will be driving however looks like after that it will be riding weather every day through the weekend.

The only negative I see is Sym was under Carter Brothers in 2006 and the 250 was a new model so bleeding edge. When Carter Brothers appeared to have burned down their own warehouse in 2010 it tarnished the Sym Brand in the eyes of many.
Alliance/Lance has been nursing it back to health over the past few years now so today things are better than in the dark Carter Brothers years or prior to 2006(2004?) when Syms were Gray Market Bikes in the USA.
You roll the dice on one of the Dark Years or Gray Market bikes however those bikes can be had at bargain prices.

The Copper Coat would be the next step after verifying that the dowel pins are not too long. Sometime replacement heads are machined a bit shallow so shorter pins are required while other times the heads just are not flat and won't seat no matter what you do aside from haveing a machine shop true them up however the vender that sold the head should make good if its defective.

KBB is only $1,700 at a dealer with a warranty for a 2007 and they do not list any for 2006 so it could be an early production model. You know what they say, don't buy the first model year. If they had been making at least the engine for a while before that would be another matter but prior to 2007 I only see 50cc bikes listed by Sym.
Still about 5,000 miles on a 250 for $1,000 is tempting.

It's going to be 80 degrees again today. Start off in the morning before the sun rises with the liner in your jacket and a hour or so later you have to remove it because it so hot.
Took a nice ride to the beach yesterday.

You do not use RTV on a head gasket. Maybe on a base gasket but you would have to be extremely careful to not plug up the oil feeds to the head. For head gaskets you spray them with Copper Coat at best. Just spray the gasket and let it dry, don't bother trying to mask the cylinder or head and trying to coat those surfaces. I hang the head gasket from a light gauge mechanics wire from the upper timing cover bolt hole to ensure its not one with oil pressure or coolant near it. Helps keep the head and valves cooler to due to the increased heat transfer it provides. Apply a few coats without going too insane and let it tack off before installing. I will coat the gasket and let it sit overnight before installing it. www.permatex.com/products/gasketing/gasket-sealants/permatex-copper-spray-a-gasket-hi-temp-sealant/ |

Crankcase is part of the intake on a 2 stroke. If the shaft seals are going the bearings may be on their way out too.

Does that have a Bendix or a Sprague Clutch like a normal GY6? My 2007 Lance had a Sprague Clutch which are notorious for failing especially after a few kickbacks while starting. If the starter spins but does not engage the engine then this is the part that usually fails:  www.partsforscooters.com/164-15_GY6-_Starter_Clutch?sc=38&category=138718The starter is in constant engagement with the intermediate gear and starter clutch which is behind the stator on the GY6 150 so after draining the engine oil you have to remove the fan shroud, stator and right engine side cover to get to it. Here is a pretty complete video on how to replace a starter clutch that no longer engages: |
