Re: Problems getting a smooth launch
What John said, but I also wonder if your bike is running well otherwise. My LT developed a hesitation during launch a few years after I bought it.
I initially thought it was E10 fuel as it began to act up about the same time as my last gas station went to E10. However, when I had my bike apart for its clutch repair, I did several things and one of them cleared up the hesitation. The trouble is I am not sure which thing fixed it as I did several things that could have potentially been the problem. THe hesitation made smooth launches really challenging as the engine would bog as soon as the clutch began to engage. Any further engagement would stall the engine. It felt like I had a 120 cc engine instead of a 1200 cc one. I had to slip the clutch and blip the throttle to get enough RPM to launch. Once the hesitation problem was fixed, launches became pretty much a non-event again.
The things I did that might have impacted the hesitation:
1. Fixed the very leaky crankcase ventilation hose.
2. Thoroughly cleaned the carbon and varnish from inside the throttle bodies.
3. Replaced the oxygen sensor.
Do you feel any bogging or sluggishness in the engine during clutch engagement?
The dry clutch may have a little less friction zone, but it isnít that much different. I had only wet clutch bikes before the LT so I wasnít sure what a wet clutch really felt like after 11 years on the LT. However, last year I bought a KLR650 and now alternate between the two fairly often, sometimes in the same day. I personally think the wet vs dry clutch issue is much ado about nothing. My LT launches as easily as my KLR. The biggest difference between the two is that the wet clutch will take more abuse as it is cooled by engine oil which will remove the heat a lot faster than the air cooling of a dry clutch, particularly when the air is in an enclosed cavity.
