First post so hi all.
Now onto my problem(s)
I recently bought a 02 plate rs50, it wasnt running when I bought it but it was cheap enough to take a chance on.
I got it home and fired it up(took a while!)
It was smoking it's tits of so I presumed it was a headgasket and left it to idle for a few minutes, I topped up the coolant but that went all over the floor instead, I instantly turned the bike of and took the fairing of to check the problem assuming it would be a broken hose but nope.
Turns out the head was cracked, so I quickly scoured ebay for a new cylinder kit and ended up buying a 70cc kit, its only a cheap one but I bought the bike to sell on so no worries there.
New kit was fitted and although it took a while to fire up it did and idles fine with no scraping noises etc, however...
The bike is now overheating fairly quickly, I'm well out of the loop with bikes so this is where you boys come in.
It came with an open filter so I've bought a second hand airbox to go on and I've also got a 98 main jet to fit so once its run in it should have a fairly decent base setting but I need to be able to solve the overheating issue before I list it for sale.
Any ideas on where to start?
Bit of info to help you diagnose the problem....
2002 rs50 with an indicated 23k on the clock.
70cc kit fitted, rings are located fine and piston is not scraping.
Standard carb with open filter(i do have an airbox and 98jet to fit)
Aftermarket exhaust, its got an arrow backbox but the front pipe is battered with plates welded over so no idea on actual make(no washer)
Cant ride it due to not being licensed but I have rode it briefly and it dosnt stutter etc at all(not gone over 4kish yet tho)
Plenty of 2stroke oil and coolant is topped up but I havnt bled either yet(obvious first port of call but havnt had time yet)
Any help is much appreciated, btw im fine with spanners and can tackle any job its just knowing what to look for, I've been riding dirt bikes for well over 10 years and used to have a tzr125 as my road bike so I'm not new to them I just havn't messed with one in a good few years!
