Yes and no. I wasn't able to source a stiffer spring, so I designed and made a set of shorter links in the rear suspension. I've had good success with these on other bikes and the T12 is no different. The shorter links raise the rate of the suspension stiffening through its travel, accomplishing...

Thanks. I'll give that a try after putting a few miles on. Being so easy to change I'll see if I can get mine to stay clean.

Hi all. I did my second service on my new to me T12 With 20k kilometers on it today. In changing the final drive oil, I noticed the nice purple 75/90 synthetic gear oil I put in 5k ago had turned very gray. The drain plug magnet was pretty clean, but the color of the oil was a surprise. How...

Hi all. Has anyone found a supplier/ part number for a shock spring that's compatible with a '19 ES model? I've looked through the forum and found mention of springs that require custom shims and spacers, but no mention of anything directly designed for the T12 ES. Also the spring rates for the...

Hi Nate. Welcome from BC. From experience, I can tell you that the genuine Yamaha accessory skidplate is almost as durable as tin foil- duct taped to the bottom of the engine. About as useful as the sheet metal skid plate on a one ton 4x4. I'll either be doing some substantial welding and...

Hey guys. I pulled the spark plugs and had a look. Checked all the intake boots and connections. Everything looks great with no surprises. I drained the mystery gas and refilled it with fresh premium, and all seems well with no pinging. It was still pinging on my way to the gas station and...

Thanks guys. I'll fill it up with some good quality premium and give her nipples a good twist this weekend .

Thanks Don. It's only under load with moderate to heavy throttle. Under light throttle/load, it's quiet. Stock motor with no tuning.

Hahha ! Don't think I haven't thought of that with an exhaust.

Thanks Gunslinger. It's not popping on decel like it's a little lean on fuel. It's definitely a detonating/pre ignition sound. I'm an old muscle car guy and know the sound well ( like marbles in a glass jar). Causes I'm aware of are fuel with insufficient octane, carbon buildup in combustion...

Thanks. It might be worth having a peak at the plugs. I do have the maintainance records for the bike and the plugs were changed at 11k with cpr8eb9. I know detonation can also be caused by carbon buildup in the cylinder head, causing hot spots and/or high compresson, as well as the ignition...

Thank you for the feedback! I'm in British Columbia. Admittedly I don't have a lot of time on this bike and it's possible that it's just mechanical noise, but it sure sounds like pinging. I'll get some more time and fuel in it and see how it goes. I'm very impressed with it so far and looking...

Hello all! New guy here. I just purchased a '19 ES model with 15k kms on it,from a little old lady that only rode it to church on Sundays. I spent the weekend changing fluids and checking things over. I found a couple possible issues that I'd like to run by you guys. One that I think I've...
