Hi all
Hoping someone's expertise here might help.
I just bought this bike last week from a friend who never used it ( only has 900miles on it). I ran it around the yard for a half an hour or so and it seemed to run fine but was a little hard to start on occasion. Well I took it deep into the bush yesterday and worked it pretty hard, and it seemed to run okay until I realized it started getting boggy at high end and getting hot and I couldn't here the fan coming on at all. I shut it down and checked my fan, fuses and cables and it all looked good but the fan still would not come on and the bike was clearly hot but I don't think over-heating yet but close.
So I stole the wires from the headlight and wired it up to my fan so I could at least get it cooling down. After I ran the fan for a bit I decided to try starting the bike, which it did but only after a lot of cranking and throttle feathering. Once started it did stay running so we drove out. When I made it back to the road I noticed that the bike did not want to run at high speed and lacked top-end power and wanted to backfire at high RPM but did seem fine at low speeds. Once I got the bike home I changed the plug that was pretty black, but it was still hard to start and didn't want to hit high speeds.
Now once the bike has cooled-off, it won't start. It does try but just won't do it.
I am heading back to the garage right now to check the valve clearance and likely clean the carb, but I was wondering if anybody had any ideas?
Thanks and sorry for the long post
