Re: Pinging even with High octane Gas and Octane boost
I just purchased a new 2009 LT last Friday. I also own a Harley... an 03 Heritage Softail. I say that because I want to qualify the following statement and to give it some context.
Whenever I engage the LT in first gear, going from a dead stop, I find myself having to rev up the RPMs and remain in half-clutched position for quite a while longer than I would have expected in order to get the bike moving off the line. The LT seems to produce engine knock and seems to lull and lag if I do not do this. There is a narrow envelope of revving the engine and applying just a certain amount of clutch pressure to avoid this knocking while in first gear.
By comparison, the Harley is very forgiving. I can begin to release the clutch in very low RPM and if I notice the engine is lulling and sputtering, I can very quickly roll the throttle to correct the situation and get the bike moving. It is very forgiving and can be put in motion withouth paying a whole lot of attention to the amount of roll on the throttle.
I know that coming from a Harley, the entire interaction with the drive train is completely different and it may just be a case of me having to get adjusted to the new feel of the LT. Once I get up in RPMs and out of first gear, I don't "sense" anything unusual. If I roll the throttle in 4th or 5th between 3 and 4k RPM, the bike responds aggressively. But from a dead stop, this bike requires an inordinate amount of RPM to get it rolling, and it doesn't seem to have much oomph when starting out.
I'd just like to get some opinions from other LT riders. Does this sound like typical behavior for an LT? Do you find yourself having to rev up the engine to avoid what otherwise sounds like regular good old- fashioned engine knock? I know it's a big heavy bike, but it seems to require a good deal of precision on the throttle and clutch to get the bike moving without killing the engine.
Anyway, I'd really appreciate any feedback. I love the bike overall. It's a very sweet ride. It's smooth and quiet and it is the very antithesis of my Harley. It's also much kinder on my backside and doesn't rattle my teeth! Finally, next week I'll be returning to the dealer for their free 600 mile checkup and I'll mention this with the mechanics there and see what they have to say.
