1: An affordable ignition timing module that is adjustable.

This seems to be A very much talked about subject for us who own/ride/mod our XR650L's...

A ready to install fuel injection system! I believe everyone would jump on that if it was under 1k. Better fuel economy, more horse power, less emissions and most of all never having to mess with a carberator ever again!

+1 on the EFI...

Although the timing module would IMO be cheaper.

6th speed would be nice

That wouldn't be too bad, but it would be a little hard to accomplish in 10 weeks. Although, I have yet to top out my 650R and I had to be doing at least 105 this weekend. I was cruising past cars on I-80, which was parallel to the road I was on.

A ready to install fuel injection system! under $1k. Better fuel economy,

EFI system that is bulletproof, properly pre-filtered so the mexican gas can't turn to sludge.

Electric start kits under $800

Direct injection sytem? Can you retrofit an engine to do this?

Stronger and lighter gears.

A head with a shorter stroke & shorter rod?

the efi could be very do able in ten weeks, especially if you have a group of people with some mechanical skills working on it. i will even give you some incentive, you figure it out and get it working, and i will purchase the first production model :cool:

A better airfilter for the XR650R. Seems like you can't ever get the thing to seal well, especially when in the desert silt.

Definitely not a 6th gear as i'd have to go WFO and it's already way fast.
The EFI is a cool idea,so's the rotating mass thingamabob.

{here's something simple}Adjustable fork caps for the preload on the springs.(Like the drz-s i had in 2000.)It's works good if your going to ride in the sand for a day.

How about some sort of clamp on, or bolt on heat sink(s) for the head on the 650L. They used to make caps with heat sinks on them that go where the valve inspection caps go. It seems many here have high heat issues with these bikes. Maybe some extended head fins that clamp on in sequence, or some sort of finned oil lines to act as a dual purpose oil line/oil cooler.
