NSR MC28 High temp on lower cyclinder

George1980sproth » Mon Jul 29, 2019 9:16 am

HI All

I am wondering if anyone can help me with an issue? I have a MC28 Sp Rothmans honda nsr 250 and the lower barrels runs hotter than the top one. I had an issue 2 years ago where I left the fuel on and it filled both Barrels. I removed the exhausts and cleared all the fuel but the water temp ran hot and was erratic. I put this down to the fuel destroying the head gaskets and the combustion entering the water spaces so I changed the following.

New plugs
head gaskets
fresh coolant
new air filter
cleaned jets in carb and checked floats
flushed fuel tank
checked thermostat operation
checked water impellor operation

I Have had the bike for a while and I know somethings not quite right there is slight white smoke from the exhaust too. I may change the plug again as it maybe faulty and should probably replace the exhausts gaskets. I can't think what other areas I can investigate. it may just need a good ride to get things going again but am too afraid to use it knowing there is an issue.

Can anyone help?

Thanks

Ian
