I got it with the exhaust off the head. The cooling fan was already melted. When I re-attached the exhaust to the head the pipe interferes with the fan cover and barely skins the fan. Why is this?, How do I fix it? 157qmj  |

I of two possibilities , either the fan shroud has been replaced with one that is bigger the the stock one or the header has been replaced with an aftermarket one .

Or three, the quality of TaoTao is questionable at best. My EVO has some amazingly bad things like that going on. I keep plugging away fixing stuff then I find some new exciting challenge the next day.  I imagine an aftermarket header/exhaust will be the way to go to fix that. The problem is you never know until you try the parts on your scooter. - EDIT - I just noticed that might not be your TaoTao. Sorry about that. I'm just bitter about my scooter. lol  |

Lol , I I know what u mean . I know many aftermarket headers do not fit right atleast the high performance headers often need adjusted " bent or cut and rewelded at the flange ". I ve seen them touching he fan cover before but it seems to be pretty bad on that one . I just figured since it was off mAybe it had been replaced ?

Sometimes this happens with aftermarket headers, AND sometimes, even with factory parts, the combination of fan-cover, header and alignment is just off a little... It only takes a fraction of an inch here and there to cause such irritating things.
On 150's (I'm not familiar with the 50's) the "external" pipe on these headers is usually a "sleeve" around the "actual" smaller head-pipe, and you should be able to mark the area of interference, then, peen it slightly flat where it passes below the fan shroud, allowing a fraction of an inch clearance. Certainly worth a try, as it's easier (and free) than re-bending ANYTHING... Since bending ALSO starts a whole "domino-chain" of nothing fitting right, including muffler mounts, etc.
Once you get a little "wiggle-room" between the cover and pipe, you might also heat-wrap it to further protect the fan-cover. You can also cover the melted "hole" in the cover with some aluminum tape or similar heat-resistant material to keep the blowing air where it belongs... then paint the cover all one color just for appearance.
I never have liked the way these headers run BELOW the engine and ABOVE the frame. I tried several ways to run a header BELOW the frame on my old Xingyue 150 but to do so put the pipe in jeopardy of being the LOWEST part of the scooter to hit speed-bumps, etc. So... flattening of the outer pipe, heat-wrapping, total replacement with a custom part, etc. seems the best answer. I'd REALLY try flattening a "dimple" in the outer pipe first... If it works, it's the easiest solution.
Hope this helps,

The header for my high performance exhaust was off so bad that it ran the muffler right into one of the shocks .i don't like bending the headers so I cut the flange off that bolts to he head and slightly turned it and welded it back on .
