Photos of all my MC-54-250 improvements

[na1x]

Hi everyone. Well it's time to share all my work. I now have an almost perfect scoot. Here are all the low cost improvements I made.
Photo 1 and 2 are just general photos.


The next photo shows where I added the all important voltmeter.The cost was $14.00

The next photo shows the six inches of windshield I made from a piece of acrylic that I shaped with a heat gun and fastened with cyanacrolate.. ( WHAT A DIFFERENCE ). Almost no wind noise now. Total cost $3.29

The next photo shows the 25A full wave bridge rectifier and heatsink I added instead of the supplied under spec heatsink/diode to correct all the battery charging problems.

Next shows the fuse block I installed instead of the mickeymouse one that came with the scoot. This alone made quite an improvement in the charging circuit because of much less resistance.Total cost $2.49.

Next is the aux/charging receptacle I added. Total cost $6.99.

Next photo shows the charging voltage with all accessories, high beams, fan, and radio all running.This is the way it should be.

And the last photo shows the baffle I made to really improve the audio from the stereo system while traveling at higher speeds. Made from black mat board, the cost was $2.00

Well this should give you guys some cool ideas.

Happy Scootin, Joe

Loved your post! I also have an MC 54 and was particularly interested in the volt meter. Where did you get it and how did you hook it up? Actually, it would be great if you posted some details of your improvements over on the tips and tricks forum (where you obtained the parts and how it was done). Great pictures BTW. Thanks.

Hi there Tom.
I got the voltmeter from EBay. Also, JC Whitney has them. Made by Sunpro. I got the 12v from the vol/on-off control that turns the radio on and off on the left side of the panel, ( or tap the ignition switch ), and the negative could be any green wire for the ground.
I also put a drop of red paint on the gauge's lightbulb, so the color matches the rest of the guages whin illuminated at night.

I like the mods you have made to your new scoot. For me, playing around with it is half the fun! I have a mental list of similar things for my new Linhai 300 but am just enjoying the ride for now. Did quite a bit to my previous two scoots and seemed to be burned out for a while.

In pic #5 is the the 25A full wave bridge rectifier and heatsink the silver box beside the battery?
These are all really cool bikes! But My concern is the fact that there appears to be no such thing as an air-cooled 250, and most of the water cooled china-bikes seem prone to overheating.

250cc air cooled scooters are available. Look how many air cooled motorcycles are out there that are much larger than 250cc, and they run fine. However there is something to be said about a water cooled 250cc scooter. ( AWESOME ). And this JMStar of mine does not run hot at all, and the fan cycles properly, except on a really hot day. I still never see over half scale on the guage.
