How much oil did you use to refill the engine? I suspect you will find the oil visible in the sight glass tomorrow morning. However, it is unusual that the oil didn't return to the sight glass within minutes.

I filled it to the full mark. If there is no oil indicated, I'll be calling CSC. Strange problem, indeed.

If you didn't measure the amount of oil, that's the problem. You didn't add enough oil to the engine. If you fill the oil to the proper level in the sight glass, then start the engine, the oil will be distributed to the nooks and crannies of the engine. Also, if you install a new oil filter, some of the oil will be distributed to that area. Therefore, you need to fill the oil to the appropriate level in the sight glass once again, run the engine, and keep doing so until the oil returns to the proper level in the sight glass within a few minutes of stopping the engine.

I simplify the process by measuring 1.7 quarts (55 ounces) of oil to add to the engine. Using this method, I know I have the correct quantity of oil. Of course, I verify the oil level is correct after running the engine, and checking the oil level in the sight glass.

Well, ok then. I'll be adding oil again tomorrow, but I believe I have around 1.5-1.7 in it now. If you dump all 55 ounces in, the oil will go above the fill line, correct?

Yes, the initial 55 ounces might fill the oil above the proper level in the sight glass. However, after you run the engine, and the oil is distributed throughout the nooks and crannies of the engine, the oil level will drop to the appropriate level in the sight glass.

You can certainly change the oil in the manner you employed. However, you need to continue adding oil, running the engine, and checking the oil level. You must repeat this procedure until the oil returns to the appropriate level in the sight glass within a few minutes of stopping the engine.

I find the job much easier to merely fill the engine with 1.7 quarts of oil. Repeated experience has proven this is the correct quantity of oil. The oil level doesn't have to be exactly precise. A little extra oil will not harm the engine, since it will be blown out the crankcase vent tube, pass through the oil separator, and collect in the clear tube at the left, front side of the engine. If you measure 1.7 quarts of oil, you will have enough oil to safely lubricate the engine, but not so much oil that it can't be safely removed by the crankcase ventilation system.

I fill 1.7 quarts of oil, and I don't have any oil collected in the tube beneath the oil separator.

If you ran the engine for a few minutes after adding engine oil, you certainly didn't burn much oil, especially with a new motorcycle. Therefore, if you don't have an oil leak, you didn't add enough oil.

I suggest you add oil to the appropriate level in the sight glass tomorrow morning. Then run the engine for about three minutes. After stopping the engine, wait about three minutes for the oil to settle. Check the oil sight glass, and repeat the procedure, if necessary, until the oil returns to the proper level in the sight glass.

Emergency terminated. It was a measuring error on my part. Nothing to see here. Move along...move along.

I see you got one of the fastest, orange bikes, and you mounted a J.C. Whitney Travel Trunk on it! The handguards look good, Huck.

My Taobao shipment which includes my upgraded LED headlight just arrived in San Francisco, and is heading over to customs.

Glad to hear that. I've shared that tip many times, and it's all thanks to the gentleman who shared it with me. I'll let him know.

I have noticed over time that my oil level has been rising. At first I thought I was just imagining it. But I think now it could be the case.

So I have set up some marks on the ground and selected a block of wood for under the side stand.

This combined with a small mark I have made on the oil level inspection window so I can accurately monitor the oil level each time I check.

This I did last week. Today I checked the oil level and It does seem to be starting to rise.

Also when I initially set this up I removed an amount of oil to gain the correct level. This oil reeked of fuel, I don't mean a small whiff of petrol, it totally stunk of the stuff.

Probably best if I order a new injector before I start ripping things apart

Thanks! I'm really enjoying it!
