gl 1500 gears

Post by Freerider » Fri Nov 17, 2017 4:46 pm



Hi everyone new to the group just joined I have a 1500 gl 1988 trike with 79000 on the clock ever since I've owned the bike I've had crunchy gears I've had a complete clutch fitted a couple of thousand miles ago but that didn't stop it I thought it was just me crap at changing gears but it is OK when cold after start up they click in smoothly but as it warms up you get the occasional crunch sometimes quite a lot it's OK when changing down with a little revs I've changed the oil and filter regularly with the correct oil as specified I was told the 1500 is prone to clunky gear changes any help would be greatly appreciated thanks Brian

The 1500's are kinda clunky shifting by nature, but check out this link, it may help a bunch.

They say 98% of all Hardleys ever made are still on the road..... The other 2% made it home. :lol:

I've seen quite a few comments over the years regarding clunky shifting on the 1500s. Mine is a little such, but totally liveable. As shift smoothness is effected by engine oil, I finally settled on Mobil1 10w40 bike oil, after testing a few synthetics, as i am partial to synthetics. But, over the years, many have recommended the Chevron DELO 400 as the single smoothest shifting oil for a GL1500. There does seem to be somewhat of a consensus on that recommendation. I've never tried it, as it is not a synthetic, but if shifting is a prime consideration for you, you may want to try it.

I have shaft stabilizer, few months ago I changed oil to car oil. It made a huge improvement how soft and nice gears are now cold and hot. Never go back to mc oil.
I would try it, you may be surprised how good transmission feels...

Mobil super2000 10w-40. This viscocity don’t have those slipping reducers (wet clutch).
Other viscocoties have, so with this brand/model it must be 10w-40.
We don’t have Mobil 1 High Mileage available here what Admin mentioned (link in my prevoius post)
Now I have Delvac 15w-40 (diesel eng oil) in, but I’ll know that next spring when riding season starts.
Delvac is commonly used with mc’s what I’ve read on local mc forums. Always comments been positive how tranny works. Never seen any bad facts...

Look around to see what you can find for Diesel Synthetic oil, most of the Synthetic oils mentioned here (Shell, Chevron, Mobil) are oils designed for Diesel over-the-road trucks. Certainly there are brands available in the UK, and if you can find a stamp on the bottle that indicates JASO-MA certified there's no friction modifiers and your bike should be more than happy with them....

I've sent emails to both chevron uk and shell uk to ask if there is a uk equivalent to delo or rotella but have not had a reply a bit naff really will just have to look for a diesel oil and give it a try. I have changed the clutch fluid when the new new clutch was fitted so shouldn't be a problem there will let you know if I can find any oil also asked at my local auto parts supplier but they couldn't find a cross reference for the shell or chevron

I use U.S. Castrol GTX 10W40 car oil in my 88 and it shifts nice and smooth. Just getting ready to turn 70K miles. Not sure if it is the same stuff as the Castrol you get in the UK. I change it every 5K miles.

Hi I had a similar problem with mine. on a 89 Trike I removed clutch slave cylinder and cleaned it up. fitted new seals I also placed a small washer between the lifter rod and slave cylinder piston works fine just a small clunk now and then.

would recommend flushing out the fluid first
