sleeper06 Posted March 1, 2016 Report Share Posted March 1, 2016 Start the bike with rad cap off, if it sparays out you got a compromised head gasket or oring . More than likely it's an air leak of some sort. If someone has a pressure test kit it couldn't hurt Quote Link to comment Share on other sites More sharing options...
JasonB Posted March 1, 2016 Author Report Share Posted March 1, 2016 Someone suggested I ditch the overflow bottle and run a line to my boot so I know when it's overheating or spitting coolant cause it's hot. That it won't be spitting coolant unless it's right before the point of hurting the motor and should be shut off. So I did that And it's just dribbling out the line non stop when the motor is running, I assumed it would lose some of the coolant to find a happy level with the coolant bottle removed from the system but it's just dripping out almost non stop. Just riding for 10 minutes I got the temp up to 245 on the gauge I have at the water outlet at the head. I lost a small amount of coolant looking into the rad it's about 3/4" below the opening for the cap so maybe only a few ounces? It seems to be slowly dribbling out whether it's hot or still warming up to operating temps. I ran it earlier with the cap off the rad, it was fine ( not shooting out) but the level slowly raised over a few minutes as it got hot. If I had a bad o ring on the head I would be losing coolant whether it was hot or not right? Quote Link to comment Share on other sites More sharing options...
JasonB Posted March 1, 2016 Author Report Share Posted March 1, 2016 once it cools down; pop the radiator cap and start it; see if the water is circulating. It could have melted or broke the water pump gear or impeller. If it has sat a long time, the radiator could be clogged. When you pop the radiator cap off, look in the radiator and see if the passages are blocked at all. Head gasket or oring could be bad which would cause a problem too. Good luck, Let us know what you find out. With the cap off I can't tell the the fluid is circulating at all. It looks still. The radiator is one of those brand new oversized set ups and it gets hot as hell so I have to believe the motors circulating coolant through there. The water pump is a new high flow billet set up and it looked fine when we had the motor apart a month ago. Quote Link to comment Share on other sites More sharing options...
Sheedawg28 Posted March 1, 2016 Report Share Posted March 1, 2016 Check if your fuel line is bubbling up and has bubbles if you have a line that you can see through and check. With t bouncing around the choppy sand you could be getting pockets of air into the carb. Also if it's an o-ring in your cool head you'll see one side or both spitting out whiter than normal and little bits of water at the ends of them. You can also take your spark plug out and smell it or see that it's wet. Quote Link to comment Share on other sites More sharing options...
Strm Trpr Posted March 1, 2016 Report Share Posted March 1, 2016 So, you're not seeing any flow with the cap off? Are you still running the plastic water pump gear? Sometimes people break those plastic gears when slipping the clutch cover back on. Quote Link to comment Share on other sites More sharing options...
JasonB Posted March 1, 2016 Author Report Share Posted March 1, 2016 We stuck the stock radiator back on in place of the oversize unit. It had some aluminum shavings on the cap and we just figured it was a good idea to swap back to stock and see how it did. Headed out for a night ride to see how hot it gets Quote Link to comment Share on other sites More sharing options...
JasonB Posted March 1, 2016 Author Report Share Posted March 1, 2016 Ran real good for the night ride, I think the oversized rad might have had some blockages or issues cause the bike ran awesome out there tonight. Will update tomorrow after more runs. Quote Link to comment Share on other sites More sharing options...
hoppedupandcutdown Posted March 1, 2016 Report Share Posted March 1, 2016 I'm guessing your cap wasn't sealing on the new rads neck 1 Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted March 1, 2016 Report Share Posted March 1, 2016 Note to self, i'm going to make sure my china radiator doesnt have this issue. Quote Link to comment Share on other sites More sharing options...
hoppedupandcutdown Posted March 1, 2016 Report Share Posted March 1, 2016 Also good to always wipe the schmutz out of the inside of an old cap. Quote Link to comment Share on other sites More sharing options...

Will update tomorrow after more runs. Sounds like you may have found your problem. Excellent! Now go enjoy that nice warm sand. Make a few passes for all of us up here in winter country. We're hoping the snow is all gone by the time St. Anthony opens on April 1. Quote Link to comment Share on other sites More sharing options...
Strm Trpr Posted March 1, 2016 Report Share Posted March 1, 2016 Man, I'm glad it wasn't your water pump gear. I've always wondered about those chinese radiators. Might be worth hooking up a shop vac or compressed air and blowing thru it to see if shavings fly out... Quote Link to comment Share on other sites More sharing options...
bluebanshee98 Posted March 1, 2016 Report Share Posted March 1, 2016 I'm not sure which one he got but the cheap oversized radiators I have got on eBay over the years never had any issues Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted March 1, 2016 Report Share Posted March 1, 2016 I've put many ebay rads on many bikes. Never an issue. This is the first issue I've heard of. Other then slight fitment issues. But all usually resolved pretty easily. Quote Link to comment Share on other sites More sharing options...
hp2000 Posted March 1, 2016 Report Share Posted March 1, 2016 eBay radiators work great haven't had issue here either. I'm more inclined to say this guy has a jetting issue for sure. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
