Plug Diagnosis and Oil Consumption (with pics)

Post by Desert_75 »

Hello all. Starting to ride the GT750 on short rides testing reliability issues. The bike has Jemco chambers and is jetted accordingly with Uni pods. I removed the oil pump and verified it worked prior to its initial start.

Here's a few pics of the plugs. They are a little darker than tan but look pretty good. (little bit of oil smeared on the tip).

Took her out for 30 minutes yesterday, I was pretty hard on her. Lots of hard accelerations (love the noise), minimal if any smoke once warmed up. I burned through 350ml of Motul 710 during the 30 minute ride, which I think is alot.

Any comments on oil consumption would be appreciated.

8) Hi,early road tests back in the day quoted about 250 miles to the pint (imp)
without doing a conversion...your consumption seems a little excessive ? lots of revs will make a difference of cause :shock: Plugs look a little rich,mine are similar in appearance,so nothing to worry about.
Cheers,
Roger

Thanks for the input. I admit I run it a tad rich on purpose so that's good you noticed that! As far as ripping the throttle, yeah I was on it ALOT. I'll try and take it out next weekend on a long ride and compare. I remember when I was a kid riding little 125 and 250 dirtbikes and a cap of oil per tank was all you needed. I guess these big 750 triples suck a lot more haha.
