That would be greatly appreciated. Thanks.

I wonder why Honda changed that page in the 2016 manual? Mine says to use 10-30. No alternatives offered. No temperature-range chart.

What year is your Rebel? Any chance you could throw up the cover page to that manual showing model and model year? Thanks!

His signature indicates he has a 1987 Rebel 250.

Thanks. Yup. I did notice that.

I just wanted to confirm that the manual matches his model year. Buickguy posted a similar oil chart, but it actually has some different temperature ranges. His signature indicates that he too owns a 1987 Rebel. So I was wondering about the discrepency.

In any event, it seems possible that after 20 years Honda changed the oil spec. Maybe based on accumulated data? Or maybe they were just trying to save ink in later years.

Thanks for that.

So this info seems to be coming from a service manual dated 2006, as opposed to an owners manual for your 1987 Rebel. I suspect Buickguy's chart also came from a service manual.

I need to find the Honda/OEM service manual for my 2016. If it has similar guidance I would be comfortable switching to 10-40. I am (hopefully) doing the first oil change today at 500 miles but will stick with the 10-30 since I have not confirmed an alternative recommendation for my model year. Which gives me some pause since temps here are well into the 90s.

I still wonder if hard shifting when warm could be caused (in some cases) by the higher viscosity oils. Not saying every Rebel would experience this, just that some might be more sensitive to it.

My 1996-2008 Honda service manual recommends 10W-30. The engine didn't change after 2008, so it's applicable to the 2016 as well. If you stick with Honda's recommendations of changing the oil every 4,000 miles with 10W-30, I'll wager the engine isn't going to last as long as those with shorter change intervals with oils appropriate to the temperatures they operate in.

Ok so I had the bike out it still does it, shifting would start to get harder after about a mile and almost impossible to shift after about 5.5 or 6 miles, I didnt pay attention when it started getting tighter but at 7.4 miles I couldn't shift again.

Bike has 10-40 in it per the owners manual its heat related so I pulled out the infrared thermometer and got about 160 anywhere on the crank case I shot it at, about 260 on the cylinder head by the exhaust port and the head by the plug the side and back if the head and jug were all about 220. I dont know exactly where the trans is on these things to try to get a temp of the trans if possible.

So my mind is going to transmission oiling or lack there of and the trans is overheating possibly but not the engine? But I dont know how the boiling system on these is for the trans. I know my trail 90 there is a small hole that the oil gets to the trans that is known to get plugged up, anything like that on these things that I should be looking at/for before I finally bite the bullet and just take it to a shop?


I should add the bike has 1300 miles on it and those temps where taken after a long steep hill

Thank you for all the help

Michael

160 degrees doesn't sound too hot to me, but I've never measured the temperature on mine. The faster the bike moves, the cooler the engine will be. Here's an article on engine oil temps: https://www.hotrod.com/articles/engine-oil-temperature/

Never heard of a problem with transmission oiling on a Rebel, but there's always the possibility of a first time.

Since someone had moved the shift assembly as evidenced by the dots not aligning, I'm wondering if they didn't also move/adjust the linkage rod? If things aren't parallel, as shown in the earlier diagram, that could make shifting harder. But it still doesn't explain shifting going from good to terrible as the engine warms.

I'll go back to the linkage and make sure the arms are parallel, however in the picture I saw of the linkage the arm was at about 7 o clock which is where mine was. When I line the dot on the arm with the mark on the shaft it puts it at 6. If I get the arm and lever parallel with the adjusting rod, does it matter if they are in 5 6 or 7 oclock or is it straight line the dots up. I'm asking this because I have a metal plate in my left ankle and dont have full range of movement incase the dots put the shifter in a bad spot for me
