upon closer inspection it appears to be leaking from the drain bolt. I took the housing off and the gasket looked good.   I peeled the old gasket off. it tore as it was stuck pretty good. So I made a new one. Was going to pull the pump off of case but the two hex head bolts were really stuck and I didn't feel like breaking them off at this time. so I put new gasket on and noticed when I tightened up the housing that the three allen head bolts were just a little bit long and the housing didn't tighten up real good so I ground a little off the end of the bolts and it snugged up good. I need to find the proper size copper crush washers for the drain bolt. I have not had a chance to run it yet and see if it still leaks. Roy |

Yes, I do have a pressure tester, but not needed. After I got it out in the drive and up where I can see without standing on my head I confirmed it is leaking at water pump housing. I am going to pull it off tomorrow and see what kind of seal it is. I don't know if it is gasket or o-ring seal, as I haven't had to tear into it yet. Hope it didn't do any damage to cylinder or head. If so I may upgrade to 74mm piston.

Last time I rode my magnum a head light bulb burned out. So I ordered bulbs. When they finally arrived I went out to change them. I noticed a puddle of fluid under the trike.I proceeded to take off the plastic to get to the coolant fill neck and noted that the coolant over flow bottle was empty. it wasn't running hot according to the gauge. so think it started leaking after I parked it. I took off the radiator cap and it was also empty. I am not sure where it is leaking from yet but appears to be water pump. Will have to get trike outside where I have room to work on it.

The only wrong kind of helmet is one that doesn't fit properly and not dot approved. Looks are secondary. That being said I like my GMax 54s. It fits me well and looks good.

perhaps the taper on crank and taper in in flywheel is not a good match. If not the flywheel will not tighten on shaft properly.

My 2010 magnum 300R has the forward/reverse shift lever on the left handle bar. A Lot of people said there's didn't work. With proper adjustment of the cable I don't have any problem shifting direction. I move shift lever and slowly give throttle to make sure gears are engaged.

Thanks guy's. I know you cant use a 6 pole stator with an 8 pole flywheel. Just wasn't sure on the 11 pole stator and didn't have time to test them today.

I have an 8 pole stator and plan on upgrading to an 11 pole. Can I use the same flywheel or do I have to change it also? They are the same size and look identical. I'm not sure on the number of magnets in the 11 pole flywheel though.

Not all HID's do that. The ones I had were one piece reflectors just like H/L beams. Yes, you are correct some hid bulbs are hi/low. Is yours the moving bulb type? Roy |

Does this Scooter have 4 lights total? With the kit you ordered you will need separate high beam lights. or use a projector housing with a mechanical device to redirect the beam. Hid housings us a solenoid to move a cutoff shield inside the housing.

Got a link to that hid kit?

That is some good information. I did a write up some time back about 50cc oil pumps.
There are two different oil pumps for a 139qmb engine. One pump uses a 47 tooth driven gear and a 22 tooth drive gear on the crankshaft. The second pump uses a 33 tooth driven gear and a 16 tooth drive gear on the crankshaft. The first pump turns at a ratio of 1:2.1363 and has internal gears that are 10mm thick. the second pump turns at a ratio of 1:2.0625 and has internal gears that are 8mm thick. The first pump has thicker gears and would move a greater volume of oil if both pumps turned at the same ratio. The drive gears on these two pumps are not interchangeable. I have taken the shaft out of a 47 tooth gear and machined the hub that was imbedded into the plastic gear off. I then bored the hole in the center of a 33 tooth gear and pressed it onto the machined shaft. The crankshaft I have has a 16 tooth drive gear and I can now use the pump with thicker gears turning at the faster ratio of 1:2.0625. This should increase oil flow volume and pressure. I have not tested this yet, but I will do a test on oil flow volume and pressure at given rpms for the two stock pumps and the pump with the modified gears.
I didn't get around to testing the pump but haven't had any oil issues.

Any body happen to know what size the radiator hoses are on the ice bear magnum? Figured I would ask here before tearing all the plastic off just to find out. I am thinking of putting a trail tech vapor on the magnum and need to know what size temp sensor to get.

An 18 pole is as good as it gets unless you go with a custom hand wound one I would think,,,looks like you have it covered,,,I'm surprised the 300 isn't awash in power with an 18 pole It should have plenty of juice. I tried to convert the head light to hid. 35w hid's consume less power than 35w halogen when heated up and light output is more than 55w halogen. problem is they pull aprox. 8amps to start bulbs. This is to much power for both lamps to start at same time. I got lazy and just put halogen bulbs back in rather than install separate switches and relays for each bulb. plus the projector housings are designed for halogen bulbs and not hid's. The will work but hid bulbs tend to cause glare in halogen projectors. H1 Hid bulbs are longer than H1 halogen bulbs. I have hid projectors, but these head light assemblies are a real pita to get apart. Probably will order stator and regulator. just to have spares. I like to have lots of spare parts. As I would rather ride than wait on shipping. Roy |

Ya. 11 pole stator going in. I already switched to led's when I did the efi. The magnum also already has led's. I found some 35w h1 bulbs for the low beam head lights. 35w h1 bulbs are hard to find. I Haven't looked for stator for the 300 yet. it has an 18 pole stator on it.
